Intrapericardial isolation of the inferior vena cava through a transdiaphragmatic pericardial window for tumor resection without sternotomy or thoracotomy.

AIMS: The prognosis for patients with advanced tumors invading the inferior vena cava (IVC) is dismal and surgical treatments for these tumors are challenging. A surgical approach that avoids sternotomy and thoracotomy for tumors invading the IVC even to the level of the hepatocaval junction would be extremely helpful. METHODS: The intrapericardial IVC was isolated via a transdiaphragmatic pericardial window using a transabdominal approach. Hepatectomy was then applied via an anterior approach until the IVC was seen. Total hepatic vascular exclusion was achieved by clamping the portal triad, intrapericardial IVC and infrahepatic IVC. We removed the primary tumor, the liver portion involved and the tumor thrombi, with segmental resection of the IVC. Vascular continuity was reestablished using a 20-mm-diameter polytetrafluoroethylene graft. RESULTS: Four patients with tumors invading the IVC were treated with this method. All underwent gross en-bloc tumor resections and all survived. CONCLUSION: This method for the resection of IVC tumors could avoid emboli dislodging from the tumor thrombi, prevent the complications of sternotomy, cardiopulmonary bypass and shorten operative times.

Rapid serodiagnosis of Staphylococcus aureus surgical site infection following median sternotomy.

OBJECTIVES: To determine the sensitivity and specificity of a novel ELISA for the serodiagnosis of surgical site infection (SSI) due to staphylococci following median sternotomy. METHODS: Twelve patients with a superficial sternal SSI and 19 with a deep sternal SSI due to Staphylococcus aureus were compared with 37 control patients who also underwent median sternotomy for cardiac surgery but exhibited no microbiological or clinical symptoms of infection. A further five patients with sternal SSI due to coagulase-negative (CoNS) staphylococci were studied. An ELISA incorporating a recently recognised exocellular short chain form of lipoteichoic acid (lipid S) recovered from CoNS, was used to determine serum levels of anti-lipid S IgG in all patient groups. RESULTS: Serum anti-lipid S IgG titres of patients with sternal SSI due to S. aureus were significantly higher than the control patients (P<0.0001). In addition, patients with deep sternal SSI had significantly higher serum anti-lipid S IgG titres than patients with superficial sternal SSI (P = 0.03). Serum anti-lipid S IgG titres of patients with sternal SSI due to CoNS were significantly higher than the control patients (P = 0.001). CONCLUSION: The lipid S ELISA may facilitate the diagnosis of sternal SSI due to S. aureus and could also be of value with infection due to CoNS.

Median sternotomy versus thoracotomy to resect primary lung cancer: analysis of 815 cases.

BACKGROUND: We sought to determine if median sternotomy (MS) is an equivalent incision to thoracotomy (TH) in the treatment of primary pulmonary carcinoma. METHODS: We followed 801 patients undergoing 815 operations for primary lung carcinoma in a computer registry; 447 had MS, 368 had TH. RESULTS: Both groups were similar in preoperative risk assessment. Complete staging lymph node dissections were performed in 42% of MS patients and 17% of TH patients. Operative mortality (3.8% for MS, 3.3% for TH) and postoperative complications were similar. MS patients had a shorter postoperative hospital stay (7.5 days vs. 8.2 days). One hundred thirty-nine underwent pneumonectomy. Operative mortality was 12.5% for MS and 10.4% for TS (p = NS). Five hundred eighty-one underwent lobectomy with an operative mortality of 2.1% for MS and 2.0% for TH. Mean length of stay for MS lobectomy was 7.5 days compared with 8.5 days for TH (p = 0.06). Follow-up was 89% through 1998, comprising 1,339 MS and 1,463 TH patient-years. Survival for stage I at 5 and 10 years, respectively, was 51% and 34% for MS vs 54% and 32% for TH (p = NS). Survival for other stages was also similar. CONCLUSIONS: Median sternotomy provides more complete staging, shorter postoperative hospitalization, and better patient acceptance with equivalent operative and long-term survival when compared with thoracotomy. Concerns regarding increased wound infections in MS patients appear unfounded.

Manubrium-sparing sternotomy and off-pump coronary artery bypass grafting in patients with tracheal stoma.

The presence of a tracheal stoma in patients with previous total laryngectomy who require cardiac operations is associated with an increased risk of wound complications and tracheal injuries when a full sternotomy is used. The aim of this report is to describe a technique of manubrium-sparing sternotomy, which can be used in patients undergoing coronary artery bypass grafting without cardiopulmonary bypass.

Reversed-T upper mini-sternotomy for extended thymectomy in myasthenic patients.

A minimally invasive approach for extended thymectomy in myasthenic patients is described. Through an 8- to 10-cm midline skin incision with a reversed-T upper mini-sternotomy, an extended thymectomy was performed. The mediastinal fat was removed beginning from the diaphragm up to the thyroid gland, and to each phrenic nerve, laterally. Extended thymectomy through a reversed-T upper mini-sternotomy warrants complete excision of thymic tissue while allowing a short hospitalization and good cosmetic result.

A rational approach to wound difficulties after sternotomy: the problem.

One hundred fifty-one patients with mediastinitis after median sternotomy were treated by a single surgeon over a 6-year period. The infections were analyzed in regard to the depth of infection, time of presentation, and the mediastinal defect. Preoperative evaluations included computed tomographic (CT) scans, testing for sternal stability, and the level of contamination. Intraoperative evaluations included bone, inflammatory tissues, Gram stain, and cultures. Treatment options included rewire procedures (20 patients), immediate reconstruction (63 patients), or delayed reconstructions (88 patients). The issues of exposed prosthetic material, right ventricular laceration, long-term intravenous antibiotics, Candida infections, and reexploration of the healed mediastinum after flap reconstruction are discussed. The overall approach to postoperative healing difficulties after sternotomy is examined.

Ruptured thymoma causing mediastinal hemorrhage resected via partial sternotomy.

A case of a ruptured thymoma causing mediastinal hemorrhage and hemothorax that was electively resected by a partial sternotomy approach is presented. This case and others previously reported illustrate that a sudden onset of dyspnea and chest pain accompanied by acute mediastinal widening on chest roentgenogram in a previously healthy patient should suggest the diagnosis of a ruptured thymoma. An upper part sternotomy approach may be as safe and effective as a less invasive surgical procedure in resection of noninvasive thymomas, even if dense tumor adhesion exists.

A biomechanical comparison of three sternotomy closure techniques.

BACKGROUND: A biomechanical study of three sternotomy closure techniques (figure-of-eight stainless-steel wires, Pectofix Dynamic Sternal Fixation [DSF] stainless-steel plates, and figure-of-eight stainless-steel cables) was conducted to compare strength and stiffness variables in three clinically relevant loading modes (anterior-posterior shear, longitudinal shear, and lateral distraction). METHODS: All tests were conducted on polyurethane foam sternal models that simulate the properties of cancellous bone. Each model was divided longitudinally and reconstructed using one of the sternotomy closure repair techniques. Tests were performed using a materials testing system that applies a continuously increasing amount of force in one direction to the model until it catastrophically breaks. A total of six trials of each fixation type in each of three test groups were prepared and tested, for a total of 54 tests. Strength and stiffness variables as well as a post-yield analysis of failure were evaluated. RESULTS: Sternums repaired using the DSF plate system are a more rigid construct than sternums repaired using the stainless-steel wires or cables in the distraction and transverse shear modes and they are not significantly different from sternums repaired with wires or cables in the longitudinal shear mode. The DSF plate system offers a 25% improvement in resistance to failure (yield) compared to wires when a transverse shear force is applied to the model. The cable system had a higher resistance to failure than the wires in all modes although the differences were not statistically significant. Additionally, the DSF plate system provides substantial reduction of the implant's cutting into the sternal model under loading as evidenced by the post-yield displacement when compared with either cables or wires for the distraction and longitudinal shear modes. For the transverse shear mode, the cables or wires would completely fail at the load for which cutting begins for the DSF. CONCLUSIONS: Both the DSF plate system and the stainless-steel cable system offer important advantages over figure-of-eight wire for sternal closure.

Left ventricular assist device implantation via left thoracotomy: alternative to repeat sternotomy.

Repeat sternotomy for left ventricular assist device insertion may result in injury to the right heart or patent coronary grafts, complicating intraoperative and postoperative management. In 4 critically ill patients, left thoracotomy was used as an alternative to repeat sternotomy. Anastomosis of the outflow conduit to the descending thoracic aorta provided satisfactory hemodynamic support.

Mitral surgery after prior cardiac operation: port-access versus sternotomy or thoracotomy.

BACKGROUND: In reoperation for mitral valve disease, minimally invasive Port-Access (PORT) is a new alternative to standard median sternotomy (STER) or right thoracotomy (THOR); yet, the results of PORT in this setting have not been defined. The aim of this study was to evaluate the results of minimally invasive thoracotomy in reoperation for mitral valve disease. METHODS: Retrospective results are reported for three consecutive series of patients undergoing reoperation for mitral disease using either PORT (n = 60, 1996 to 2001), THOR (n = 37, 1985 to 1997), or STER (n = 155, 1985 to 1997). RESULTS: Red cell transfusion was 3 +/- 4, 14 +/- 13, and 12 +/- 12 units for PORT, THOR, and STER, respectively. Chest tube output was 352 +/- 361, 2048 +/- 3166, and 1683 +/- 3939 mL, respectively. Cardiopulmonary bypass times for these groups were 208 +/- 76 vs. 158 +/- 56 vs. 157 +/- 53 minutes. Thirty-day mortality was 0/60 (0%), 8/37 (22%), and 21/155 (14%), respectively. CONCLUSIONS: This early clinical experience suggests that PORT is an acceptable alternative to THOR or STERN in reoperation for mitral valve disease, with potential advantages of avoiding redo sternotomy and reducing the surgical incision. However, these benefits may come at the expense of longer cardiopulmonary bypass times.

Management of large aortopulmonary collateral arteries in patients with ventricular septal defect and pulmonary atresia: simultaneous ligation through median sternotomy during intracardiac repair.

Nine consecutive patients with ventricular septal defect (VSD) and pulmonary atresia associated with large aortopulmonary collateral arteries underwent primary repair with simultaneous ligation of these collateral arteries. The patients ranged from 1 year to 20 years old (average, 8.0 years). The average number of large aortopulmonary collateral arteries was 1.9 per patient. Arborization abnormality was found in 5 patients. The aortopulmonary collateral arteries were reached solely through a median sternotomy, with dissection of the posterior pericardium or anterior mediastinal pleura before or after the initiation of cardiopulmonary bypass. The immediate postoperative peak pressure ratio between the right and left ventricles was higher in patients with an arborization abnormality, but all ratios ranged from 0.60 to 0.87. There was 1 operative death. Postoperative transcatheter embolization for a residual large aortopulmonary collateral artery was required in 1 patient and pulmonary infarction of mild degree developed with spontaneous recovery in another. These results indicate the usefulness and safety of simultaneous ligation of large aortopulmonary collateral arteries through median sternotomy, even with an associated arborization abnormality.

Median sternotomy T incision for thymectomy in myasthenia gravis.

Controversy exists over the surgical approach for thymectomy for myasthenia gravis. Opinion is divided between transcervical thymectomy and transsternal thymectomy performed through a median sternotomy. A technique that combines the advantages of a small, cosmetic T incision with good visualization through a partial sternotomy is presented. We have utilized this technique in more than 35 patients during the past ten years with excellent results.

Curvilinear paramedian sternotomy.

A modification of the classic straight midline sternotomy incision is described. The technique involves performing the sternotomy in a curvilinear manner along both sides of the midline to create two sternal halves that interdigitate with one another. With such a configuration, malalignment is virtually impossible.

Upper rib fractures following median sternotomy.

First and second rib fractures occurred in 11 (16%) of 69 patients undergoing median sternotomy. Although 6 patients had no symptoms related to the rib fractures, 5 patients had postoperative chest, shoulder, and arm pain suggestive of angina pectoris or postpericardiotomy syndrome. The correct diagnosis of pain related to postoperative upper rib fracture may be made by direct visualization of the fracture on supine anteroposterior radiographs, elicitation of pain by palpation of the rib or motion of the upper extremity, lack of response to nitroglycerin, and negative electrocardiogram and cardiac enzyme levels. Upper rib fractures following median sternotomy are usually radiographically detectable within the first three postoperative days. Placement of the Ankeney sternal retractor with the upper blade in a lower position (fourth intercostal space) may reduce the incidence of this postoperative complication.

Repeat median sternotomy in pediatrics: experience in 164 consecutive cases.

One hundred thirty-eight children underwent 164 operations through repeat median sternotomy. Ages ranged from 4 months to 21 years (mean, 8.6 +/- 5.0 years). The technique consisted of opening the sternum with chisel and mallet, avoidance of sudden separation of sternal edges and blunt dissection, elimination of the electrocautery during lysis of adhesions, and judicious use of fresh blood and components. Several variables were analyzed comparing the initial and repeat procedures on each patient. Time from incision to bypass was an hour longer with the repeat procedure (174 +/- 45 minutes versus 96 +/- 37 minutes). Operative transfusions and postoperative bleeding (first 48 hours) were not significantly different between the two procedures. Cyanosis, however, significantly increased bleeding in both groups. There were eight injuries (5%) at reoperation. During sternal reentry in 2 patients, a tear occurred in a valved conduit coursing underneath the sternum. A right ventricular tear occurred in 1 patient while the sternal edges were being separated. Ventricular fibrillation was noted in 2 patients during lysis of adhesions with the electrocautery used early in the series. Intimal disruption occurred in two valved conduits during intraoperative manipulations. An aortic tear occurred and was repaired without cardiopulmonary bypass. There were 13 (8%) hospital deaths, all unrelated to the technique. We believe that the current approach can be a valuable alternative for surgeons dealing with repeat median sternotomy in children.

Submammary skin incision as a cosmetic approach to median sternotomy.

Median sternotomy is the incision of choice to allow access to the anterior mediastinum, heart, or both lungs. The vertical skin incision leaves an unsightly scar for many female patients. A bilateral submammary horizontal skin incision with dissection of a flap including the subcutaneous tissue and breasts allows exposure of the sternum so that a median sternotomy can be performed. Since November 1981, we have used this incision 40 times in female patients undergoing open heart surgery. The exposure of the mediastinum was excellent, and there were no difficulties in cannulating the ascending aorta for cardiopulmonary bypass. Complications associated with this incision are insignificant if close attention is paid to details.
