Penile prosthesis surgery: review of ten-year experience and examination of reoperations.

Our ten-year experience from September, 1975, to December, 1985, with 417 penile prostheses in 290 patients is presented. Arteriosclerosis and diabetes mellitus were the two most common causes of impotence in our patient population. The Scott inflatable penile prosthesis accounted for the majority of all implants and all device failures. Complications leading to device failure and/or reoperation occurred in 36 percent of all prostheses. However, including repairs, 91 percent of patients were left with a functional prosthesis. Examination of reoperated patients showed an average increase in corporeal length of 1.67 cm with repeat prosthesis operations (p less than 0.001). No increase in incidence of prosthesis failure could be shown after multiple reoperations.

Closed transventricular aortic valvotomy for critical aortic stenosis in neonates: outcomes, risk factors, and reoperations.

BACKGROUND: Critical aortic stenosis (AS) in neonates necessitates urgent intervention for patient survival. The optimal treatment, however, continues to be controversial and still has high morbidity and mortality in many centers. This study examined our late outcome, risks, and reoperations after the treatment of critical AS in neonates. METHODS: Sixty-six neonates (47 boys and 19 girls) underwent closed transventricular aortic valvotomy for critical AS between 1978 and 2000. The mean age at the first intervention was 15.1 +/- 19.6 days (range, 1 to 78). Their weight ranged from 1.4 to 6.2 kg (mean, 3.5 +/- 0.9 kg). Sixteen patients (23%) had isolated critical AS and normal or dilated left ventricles, and 50 neonates (77%) had associated cardiovascular anomalies (ie, aortic annular hypoplasia, hypoplasia of the left ventricle, mitral valve abnormalities, and endocardial fibroelastosis, coarctation, or interruption of aorta). RESULTS: The hospital mortality was 29% (19 of 66). Kaplan-Meier 5- and 15-year survival was 61% and 58%, respectively. The operative mortality rates were 6% in neonates with isolated AS and 36% in patients with complex AS. The five risk factors significant for mortality on univariate analysis were (1) presence of endocardial fibroelastosis (p = 0.05), (2) presence of hypoplastic left ventricle (p = 0.003), (3) presence of associated cardiovascular anomalies (p = 0.04), (4) aortic valve annulus of less than 5.0 mm (p = 0.01), and (5) surgery before 1985 (p = 0.003). Of these five factors, only the presence of hypoplastic left ventricle (p = 0.001) and surgery before 1985 (p = 0.001) remain significant for mortality by multivariate analysis. At last follow-up (mean, 8.2 +/- 6.2 years), 36 of 47 of the long-term survivors were in New York Heart Association functional class I and II. Kaplan-Meier analysis showed 5- and 15-year freedom from aortic valve reoperation to be 83% and 60%, respectively. Univariate and multivariate analysis showed the presence of multilevel stenosis (p = 0.04) as the best preoperative predictor for the need for late reoperation in survivors. CONCLUSIONS: We conclude that critical AS in neonates continues to be associated with significant mortality. Reintervention such as surgical and balloon valvotomy are usually required within 10 years of initial surgery.

Reoperations on the ascending aorta and aortic root in patients with previous cardiac surgery.

BACKGROUND: First time operations on the ascending aorta are performed with low mortality, few complications, and excellent long-term results. Reoperations for aortic pathology in patients with previous cardiac surgery carry significantly more risk. Technical issues during the procedure, as well as age, preoperative New York Heart Association class, and perioperative renal dysfunction, have been shown to contribute heavily to worse outcomes. We analyzed our results with aortic reoperations with the intent of further reducing surgical risk through alterations in surgical technique or patient selection. METHODS: From July 1997 until October 2005, 147 patients having previous cardiac surgery presented with aneurysm or dissection of the ascending aorta or root. Perioperative data were retrospectively analyzed. Morbidity, mortality, and risk factors for these events were calculated. RESULTS: Eight patients expired (5.4%) after their reoperation. Significant (p < 0.05) univariate risk factors for mortality included age greater than 75 years (< 0.001), previous coronary artery bypass grafting (CABG) (< 0.008), cardiopulmonary bypass greater than 240 minutes (< 0.01), need for intraaortic balloon pump support (< 0.001), need for new CABG (< 0.007), postoperative cerebrovascular accident (< 0.032), and tracheostomy (< 0.003). Age 75 years or older (p < 0.025) was the only significant variable for death by multivariate analysis. A majority of patients (n = 87, 60%) required circulatory arrest to complete their procedure. However, neither arch involvement nor type of aortic root procedure was predictive of perioperative mortality. CONCLUSIONS: Surgery on the ascending aorta and root in patients who have had previous cardiac surgery can be performed with low mortality. Advanced age and significant coronary disease may negatively influence surgical results.

The Ross-Konno procedure in children: outcomes, autograft and allograft function, and reoperations.

BACKGROUND: The Ross aortic valve replacement with a modified Konno-type enlargement Ross-Konno procedure of the aortic annulus and subannular region allows an autograft aortic valve replacement for children with significant annular and subannular hypoplasia. The potential for growth and the proven durability of the autograft make the Ross-Konno procedure an ideal aortic valve replacement for this subgroup with multilevel left ventricular outflow tract obstruction. We reviewed our institutional midterm experience to assess autograft and homograft hemodynamics, and management after a Ross-Konno procedure. METHODS: Between 1995 and 2005, 14 consecutive children (mean age, 6.4 +/- 5.9 years; range, 1 month to 17 years) underwent the Ross-Konno procedure. All children had severe to critical aortic stenosis or multilevel left ventricular outflow tract obstruction. RESULTS: There was 1 early and 1 late death with a mean follow-up of 5.7 +/- 3.6 years. Actuarial survival at 10 years was 86%. Three patients underwent right ventricular outflow tract reoperation for conduit replacement for homograft dysfunction and one patient required redo aortic root replacement with a mechanical valves for progressive aortic insufficiency. Freedom from right ventricular outflow tract and autograft reoperation at 10 years is 77% and 92%, respectively. Aortic annular dilation was not observed in all patients. Univariate and multivariate analysis identified no risk factors for autograft or homograft valve-related reoperation. CONCLUSIONS: The Ross-Konno procedure is an excellent technique to treat complex multilevel left ventricular outflow tract obstruction in children with significant annular and subannular hypoplasia. The autograft demonstrated durability without development of aortic stenosis or progressive dilation and a low incidence of developing progressive aortic insufficiency. Enlargement of the aortic annulus appear to parallel somatic growth in most instances.

Impact of mitral insufficiency on reoperative coronary artery surgery in ischemic cardiomyopathy patients.

OBJECTIVE: To determine the impact of mitral insufficiency on survival after reoperative coronary artery bypass grafting (CABG) in ischemic cardiomyopathy patients. METHODS: We retrospectively studied 891 (Initial 708, Redo 183) consecutive CABG patients (1993-2002) with ejection fraction (EF) 35% or less. PATIENT CHARACTERISTICS: mean age=67.0+/-10.5 yrs, men=77.1%, EF=26.4+/-7.4%, mean CCS=3.47+/-0.73, mean NYHA=3.50+/-0.68. There were 180 (Initial 141, Redo 39) patients with 3/4+mitral regurgitation (MR). Late survival statistics of cohorts were compiled using National Death Index. RESULTS: At a mean follow-up period of 3 years, reoperative CABG with MR (Redo/MR+) survival was 41.7+/-9.2% (n=39), which was worse than reoperative CABG without MR (Redo/MR-) survival of 71.8+/-4.1% (n=144, P=0.0003), initial CABG with MR (Initial/MR+) survival of 68.5+/-4.2% (n=141, P=0.014) and initial CABG without MR (Initial/MR-) survival of 76.2+/-2.0% (n=567, P<0.0001). By multivariate analysis, congestive heart failure (P=0.029), 3/4+MR (P=0.044) were independent predictors of Redo late mortality. In contrast, renal failure on dialysis, stroke, no angina, age >65 yrs, absence of hypercholesterolemia, EF<26% but not 3/4+MR were independent predictors of Initial late mortality. In subset analysis, adverse impact of 3/4+MR on late survival was greatest in Redo with EF<26%. The 3- and 5-yr late survival were only 44.4 and 26.8% (P=0.041). Concomitant mitral valve repair (MVrep) was performed in 100 (Initial 75, Redo 25) patients. MVrep in Initial/MR+patients achieved similar late survival as Initial/MR- patients. MVrep did not produce the same late survival benefit in Redo/MR+ patients. CONCLUSIONS: (1) Mitral insufficiency has a greater survival impact on redo than initial CABG patients with ischemic cardiomyopathy. (2) Mitral insufficiency and congestive heart failure are the primary independent predictors of late survival following redo CABG. (3) Mitral repair has less neutralizing effect on late survival in redo than initial CABG patients.

Reoperation, myocardial infarction and mortality after transurethral and open prostatectomy: a nation-wide, long-term analysis of 23,123 cases.

OBJECTIVE: To analyse long-term rates of reoperation, myocardial infarction and mortality after transurethral (TURP) and open prostatectomy (open PE) in a nation-wide analysis. MATERIAL AND METHODS: Patients who underwent TURP (n=20,671) or open PE (n=2452) in Austria between 1992 and 1996 entered this study and were followed for up to 8 years. Actuarial cumulative incidences of reoperation (TURP, urethrotomy, bladder neck incision), myocardial infarction and death after 1, 5 and 8 years were calculated. Data were provided by the Austrian Health Institute (OBIG). RESULTS: Actuarial cumulative incidences of a secondary TURP after primary TURP at 1, 5 and 8 years were 2.9%, 5.8% and 7.4%; the respective numbers after open PE 1.0%, 2.7% and 3.4%. The overall incidence of a secondary endourological procedure (TURP, urethrotomy, bladder neck incision) within 8 years was 14.7% after TURP and 9.5% after open PE. The 8 years incidence of myocardial infarction was identical after TURP (4.8%) and open PE (4.9%). In parallel, mortality rates at 90 days (TURP: 0.7%; open PE: 0.9%), one year (2.8% vs. 2.7%), 5 years (12.7% vs. 11.8%) and 8 years (20% vs. 20.9%) was identical after TURP and open PE. CONCLUSIONS: This large-scale, contemporary, nation-wide analysis confirms the higher reoperation rate after TURP compared to open PE. We observed no excess risk of myocardial infarction or death after TURP compared to open PE.

Intraoperative parathyroid hormone assay and parathyroid reoperations.

BACKGROUND: The purpose of this study was to determine whether intraoperative parathyroid hormone (IOPTH) assay improved results of reoperations. METHODS: One hundred two patients with persistent/recurrent sporadic primary hyperparathyroidism underwent 108 reoperations (1996-2002). IOPTH was not used (n=58) from 1996-1998 (group 1). IOPTH was used (n=50) from 1999-2002 (group 2). Sensitivity and positive predictive value of IOPTH and its influence on surgical strategy were analyzed. A 50% decrease occurring 10 minutes after removal of parathyroid tumor was used to determine if all abnormal tissue had been removed. RESULTS: Groups 1 (58 patients) and 2 (50 patients) were comparable except for duration of follow-up. The cure rate was 84% (group 1, 87%; group 2, 82%, P=0.7). Hypocalcemia developed in 20 patients (permanent in 2 patients). There was 1 permanent vocal cord paralysis and 1 patient died of toxic shock syndrome. IOPTH successfully predicted cure in 44 of 49 patients (sensitivity, 90%); the positive predictive value was 90%. Values for parathyroid hormone level and the ratio parathyroid hormone/calcium at day 1 were at least as accurate as IOPTH in predicting cure. IOPTH was helpful in 1 patient but misleading in 4 patients. It failed to modify intraoperative strategy in most other patients. CONCLUSIONS: IOPTH testing was relatively reliable in patients with persistent or recurrent sporadic primary hyperparathyroidism, but the test unfortunately failed to improve the overall success rate at reoperation.

Reoperation of a recurrent temporal lobe epilepsy: a technical case report.

BACKGROUND: The indications for the reoperation of a recurrent temporal lobe epilepsy, the risks, and outcome have not been well documented. The invasive video electroencephalogram (EEG) monitoring and magnetic resonance imaging (MRI) techniques can reveal the residual tissues and their epileptogenic activity so that a reoperation decision can be made. CASE DESCRIPTION: A 30-year-old patient who had recurrent temporal lobe epilepsy and had undergone 2 operations at the same temporal region is presented. After both of these operations, approximately 6 months later, seizures relapsed. Postoperative neuroimaging studies showed residual mesiotemporal tissues at the operative site. The invasive video EEG monitoring revealed epileptogenic activity originating from these residual tissues. After all of these investigations, it was thought that a third operation was indicated, and the patient was operated. Postoperative course was uneventful. No postoperative deficit was observed. Pathological examination was reported as hippocampal sclerosis. He is seizure-free at his third postoperative year. CONCLUSIONS: Complete resection of epileptogenic mesiotemporal structures at the first operation can prevent the necessity for reoperation in defined cases. The MRI and invasive video EEG monitoring techniques can reveal the residual tissues and their epileptogenic activity in a recurrent epilepsy case.

Reoperation in patients with the short bowel syndrome.

The clinical courses of 53 adult patients with the short bowel syndrome (SBS) were evaluated to determine the incidence of and indications for reoperation. Mesenteric vascular disease (23 patients) and malignancy/irradiation (18 patients) were the most frequent causes of resection. Early reoperation was necessary in nine (17%) patients, primarily for intestinal complications. Twenty (53%) of the 38 patients leaving the hospital required a later abdominal procedure during the mean follow-up of 30 months (range: 2 to 108 months). Three (33%) of nine patients with ulcer disease had gastric resection. Six (21%) of 28 patients at risk for cholelithiasis developed symptoms. Four of these patients underwent cholecystectomy, and three others had a prophylactic cholecystectomy. Ten patients underwent ostomy closure or formation. Intestinal disease necessitated stricturoplasty (three), serosal patch (one), minimal resection (three), or takedown of an ileal conduit (one). Twenty-four (63%) of 38 patients with SBS received home total parenteral nutrition for a mean of 22 months (range: 2 to 105 months). Eleven patients required more than 1 vascular access procedure, and 4 had more than 3 procedures. Patients with the SBS frequently require reoperation for intestinal conditions, cholelithiasis, peptic ulceration, and vascular access. Prophylactic cholecystectomy and strategies for preserving intestinal length are important considerations in these patients.

Long-term follow-up of reoperative carotid surgery.

BACKGROUND: We examined our long-term results of carotid reoperation to identify risk factors for morbidity and secondary recurrence. METHODS: Medical record review revealed 27 patients had reoperative surgery for recurrent stenosis. Demographics, operative details, pathology, clinical outcome, and follow-up imaging results were reviewed. RESULTS: No neurologic deficits and no mortalities were noted perioperatively. Long-term follow-up (average 54 months) revealed an 85% 5-year and 29% 10-year estimated survival. The 5- and 10-year estimated neurologic event rates were 15% and 35%, respectively. These included 3 ipsilateral strokes and 1 ipsilateral TIA; only the TIA involved secondary restenosis. Follow-up imaging revealed a 21% incidence of secondary restenosis, occurring more frequently in patients with hyperlipidemia (P < 0.05) and previous contralateral endarterectomy (P < 0.05). CONCLUSIONS: (1) Reoperation provides long-term protection from stroke due to recurrent stenosis. (2) Secondary restenosis rates appear higher than those for primary surgery. (3) Hyperlipidemia and contralateral endarterectomy are risk factors for secondary restenosis.

[Usefulness of intraoperative 123I-MIBG during reoperation for malignant pheochromocytoma: a case report].

Intraoperative MIBG radionuclear scanning has been used to improve pathological foci localization and surgical accuracy in patients with neural crest derived tumors. This intraoperative detection has been reported in less than 10 patients during reoperation for pheochromocytoma. We report a case of 123I-MIBG intraoperative detection allowing to improve surgical resection quality during reoperation for pheochromocytoma. The use of intraoperative MIBG radionuclear scanning is helpful when reoperation for pheochromocytoma is performed.

Reoperative CABG using left thoracotomy: a tailored strategy.

BACKGROUND: Reoperative coronary artery bypass grafting (CABG) through a left thoracotomy is a challenging operation with no one dominant approach. We developed a tailored strategy for this difficult group of patients, integrating the currently available newer technologies for each patient indication. METHODS: Between October 1991 and October 1999, 50 consecutive patients underwent reoperative CABG through a left thoracotomy. Age was 65 +/- 9 years, 40 (80%) were men, and preoperative ejection fraction was 40 +/- 13. In 36 patients (72%) the left internal mammary artery had been placed to the left anterior descending coronary artery during the primary CABG and in 25 of 36 patients (70%) this left internal mammary artery-left anterior descending coronary artery graft was patent. The mean duration from previous CABG was 8.0 +/- 4.8 years. Three approaches were used: (1) conventional cardiopulmonary bypass using fibrillatory or circulatory arrest (n = 33, 66%); (2) Heartport endoaortic balloon occlusion (n = 4, 8%); and (3) off-pump beating heart techniques (n = 13, 26%). RESULTS: The off-pump CABG technique was used in the majority of recent patients and 1 (7.7%) had to be converted to cardiopulmonary bypass due to hemodynamic instability. When cardiopulmonary bypass was used its duration was 122 +/- 59 minutes and mean temperature on bypass was 24 degrees +/- 6 degrees C. In the 4 patients in whom the Heartport system was used, the median endoaortic occlusion duration was 49 minutes. Patients received an average of 1.4 grafts/patient. In 60 of 70 patients (89%) distal anastomoses were performed to an anterolateral coronary target. There were 3 of 50 (6%) operative deaths, 2 in the conventional group and 1 in the endoaortic balloon occlusion group. The mean length of stay in the 47 survivors was 7.8 +/- 3.9 days (median, 7 days). CONCLUSIONS: Reoperative CABG by left thoracotomy remains a challenging operation. Several techniques, including off-pump CABG, conventional cardiopulmonary bypass, circulatory arrest, and endoaortic balloon occlusion, should be in the surgeon's armamentarium to allow a tailored approach for each operation based on patient indications.

Reoperative homograft right ventricular outflow tract reconstruction.

BACKGROUND: Homografts are implanted in the right ventricular outflow tract (RVOT) of children, with the knowledge that reoperation might be required. We reviewed 14 years of homograft RVOT reconstruction to assess the feasibility of homograft replacement and to determine risk factors for homograft survival. METHODS: From February 1985 through March 1999, 223 children (age 5 days to 16.9 years) underwent primary RVOT reconstruction with an aortic or pulmonary homograft. Of these, 35 patients underwent homograft explant at the implanting hospital with insertion of a second homograft from 2 months to 13.3 years after the first implantation. The primary operation and reoperation patient groups were compared with regard to incidence of early death, late death, homograft-related intervention without explant, and homograft explant. RESULTS: Actuarial survival and event-free curves for initial and replacement homografts were not significantly different. Univariable analysis was performed for the following risk factors: weight (p < 0.0001), age (p < 0.003), homograft diameter (p < 0.0001), homograft type (p < 0.01), surgery date (not significant [NS]), gender (NS), Blood Group match (NS), and type of distal anastomosis (NS). Multivariable analysis of significant univariable risks revealed small homograft diameter to be a significant risk factor (p < 0.001) for replacement. CONCLUSIONS: The RVOT homografts eventually require replacement. Patient and homograft survival for replacement homografts is similar to primary homografts. Reoperative homograft RVOT reconstruction is possible, with reasonably low morbidity and mortality.

Single-stage reoperative repair of chronic type A aortic dissection using the arch-first technique.

BACKGROUND: Management of the enlarged, chronically dissected aorta after previous repair of acute ascending aortic dissection or after a previous cardiac operation may present a formidable technical challenge and the optimal method of management is not clearly established. METHODS: Twenty-one patients with chronic type A aortic dissection (mean age 57 years) underwent resection of the ascending aorta, the aortic arch, and varying segments of the descending thoracic aorta. Single-stage replacement with perfusion of the aortic arch first to minimize the duration of brain ischemia and a bilateral anterior thoracotomy (clamshell) incision were used. Fourteen patients had undergone previous repair of acute type A dissection. Seven patients had type A dissection after aortic valve replacement (3 patients) or coronary artery bypass (4 patients). Marked enlargement of the aorta distal to the left subclavian artery precluded a two-stage repair. The mean interval between the initial and reoperative procedures was 69 months (range, 5 to 249). RESULTS: There was 1 (4.8%) hospital death. Four patients required reoperation for bleeding. One patient required a right ventricular assist device that was successfully removed. Ten patients required assisted ventilation for more than 48 hours. All were successfully weaned from ventilatory support. No patient had a stroke or other adverse neurologic outcome. There has been 1 late death (mean follow-up 2 years). CONCLUSIONS: The single-stage, arch-first replacement technique is a safe and effective procedure for patients who require extensive reoperations for chronic expanding type A dissection.

Management during reoperation of aortocoronary saphenous vein grafts with minimal atherosclerosis by angiography.

The proper management of saphenous vein grafts showing minimal angiographic evidence of atherosclerosis at the time of reoperation for progressive atherosclerosis in the native coronary circulation or for severe atherosclerosis in other saphenous vein grafts is uncertain. Following the occlusion of vein grafts in 2 patients 7 and 12 years after operation but only 2 years after arteriography demonstrated no major abnormalities in the grafts, we adopted a policy of elective replacement of all saphenous vein grafts, irrespective of angiographic findings, when reoperation was necessary 5 or more years after the initial operation. Between July, 1984, and May, 1985, 16 patients had repeat coronary artery bypass grafting 6 to 13 years (mean, 9 years) after the initial procedure. Complete revascularization was carried out in all patients. In each, it included replacement of at least 1 saphenous vein graft showing no severe obstruction (less than 30% of the luminal diameter) and no (5 patients), minimal (8), or moderate (3) luminal irregularities by angiography. By pathological examination, 3 of the grafts had minimal, 5 had moderate, and 8 had severe atherosclerotic changes present. These changes were generally more diffuse than those observed by angiography. Because angiography underestimates the severity of the atherosclerotic degeneration in saphenous vein grafts and because of the propensity of the atherosclerotic disease to progress at an unpredictable rate, we recommend routine replacement of all saphenous vein grafts at the time of reoperation if done 5 or more years after the initial procedure.

Reoperation for aortic coarctation.

Reoperation for aortic coarctation has become common because of several factors: (1) increased physician awareness that hypertensive cardiovascular disease continues to threaten the prognosis of the patient following coarctectomy and that investigation in some symptomatic individuals after coarctectomy will demonstrate a residual or recurrent coarctation, even many years after the primary repair; (2) the widespread application of stress testing, which can reveal marked arm-to-leg pressure gradients not observed at rest, to the routine postcoarctectomy follow-up examination; (3) improved noninvasive aortic evaluation techniques, such as ultrasound; and (4) higher salvage rates among infants undergoing urgent coarctation repairs and the recognition that these children subsequently are at high risk for recoarctation. A surgical decision-making process characterized by flexibility provides maximum patient safety; no single reoperation technique can be applied in all situations. Individual circumstances may dictate recoarctation repair by resection with end-to-end anastomosis, tube graft interposition, aortoplasty, or tube graft bypass. The need for a temporary aortic shunt or partial left atriofemoral bypass to maintain adequate distal aortic perfusion pressure during the repair means that these methods must be available at all reoperations. Diligent efforts to repair all hemodynamically significant residual and recurrent coarctations are necessary if the natural fate of premature death is to be avoided for patients with these lesions.

Thoracoscopic operations on reoperated chests.

BACKGROUND: A previous operation is generally considered to be a relative contraindication to the minimal access approach. We reviewed our combined experience from three centers with video-assisted thoracic surgery on reoperated chests. METHODS: From September 1992 to December 1996, 2,477 patients underwent video-assisted thoracic surgery of whom 40 patients (33 men; age range, 9 to 78 years) had prior operations on the ipsilateral side of the chest: 23 after prior open procedures (22 thoracotomies, 1 median sternotomy) and 17 after video-assisted thoracic surgery. The second procedures consisted of bullectomy or bulla ligation (8), mediastinal and hilar mass biopsy (8), wedge lung resection (6), pericardial window (5), lung volume reduction (4), redo thoracodorsal sympathectomy (3), talc insufflation alone (3), decortication (2), and suturing of a pleural rent (1). RESULTS: Adhesions were noted in all patients ranging from minimal to strong fibrous adhesions. However, in only 2 patients (5%) were the procedures abandoned because of adhesions. Video-assisted thoracic surgery was safely completed in all other patients. There was no mortality or intraoperative complications and mean hospital stay was 5.1 +/- 3.2 days (range, 0 to 17 days). CONCLUSIONS: Video-assisted thoracic surgery on reoperated chests is feasible and does not carry a higher morbidity or mortality compared with first-time operations, even though it may be technically more difficult. Experience and clinical judgment, however, are required to select these patients for reoperation with video-assisted thoracic surgery.

Injury to a patent left internal thoracic artery graft at coronary reoperation.

BACKGROUND: The purpose of this study was to determine the prevalence, outcome, and operative strategies for patients having injury to a patent left internal thoracic artery (LITA) graft to the left anterior descending coronary artery (LAD) at coronary reoperation. METHODS: Of 655 patients with a patent LITA graft to the LAD undergoing coronary reoperation from 1986 to 1997, 35 (5.3%) sustained intraoperative injury to the LITA graft. RESULTS: Strategies to restore flow to the LAD included new saphenous vein graft to the LAD in 15 patients, saphenous vein graft to the LITA stump in 7, saphenous vein graft to the LAD and repair of the LITA graft in 6, and other strategies in 7. All or part of the LITA graft to the LAD was salvaged in 20 patients (57%). Fourteen patients (40%) sustained perioperative myocardial infarction, and 3 patients died (8.6%). The 3 patients who died all had stenosis or thrombosis of the graft to the LAD documented at autopsy. CONCLUSIONS: We conclude that (1) the prevalence of injury to a patent LITA graft is 5.3%; (2) a variety of techniques can be used to restore blood flow to the LAD; and (3) ineffective revascularization of the LAD in this situation is associated with operative mortality. At primary coronary artery bypass grafting, the LITA pedicle should be positioned in the left chest away from the posterior sternal table; this strategy may minimize the risk of LITA graft injury at coronary reoperation.
