[Descending aorta perfusion through median sternotomy in primary repair of aortic interruption complex].

Circulatory arrest is frequently used in aortic arch reconstruction in pediatric cardiac surgery. However, risks of postoperative acute renal failure and neurological deficit can not be ignored. We performed primary repair of aortic interruption in one-month old girl. After commencing extracorporeal circulation with bicaval venous cannulae and with arterial cannulae into the pulmonary trunk and the innominate artery, the descending aorta was cannulated just superior to the diaphragm. The cannula in the pulmonary trunk was then removed. Arch reconstruction and closure of the ventricular septal defect were performed with continuous perfusion to the brain and the lower body. The extracorporeal circulation time and the aortic cross-clamp time were 117 min and 21 min, respectively. Postoperative renal function was excellent, and there was no finding of neurological deficit. Cannulation of the descending aorta is a simple and useful technique with safety, in arch reconstruction in infants.

Coronary artery bypass grafting via median sternotomy or lateral minithoracotomy.

OBJECTIVES: In order to evaluate the benefit provided through less invasive surgical techniques for the treatment of multivessel coronary artery disease, a prospective clinical trial was started. METHODS: Group 1 included 53 patients (38 males, 15 females, age 51-79 years, mean 62.8 +/- 6.1 years) receiving conventional bypass surgery, group 2 included 69 patients (59 male, 10 female, age 43-82 years, mean 61.9 +/- 8.6 years) receiving less invasive surgical procedure including minithoracotomy in combination with cardiopulmonary bypass. RESULTS: No perioperative death occurred in the whole series of patients. Time of operation was 267 +/- 61 min in group 2 and 162.9 +/- 53.6 min in group 1. Intensive Care Unit stay was 1 day for both groups and Hospitalization 6.9 +/- 6.0 for group 1 and 7.5 +/- 2.6 days for group 2. Perioperative bleeding was less in group 2 (P > 0.01). Back and chest pain assessment on postoperative day 3 showed less pain in group 2 (P < 0.05). Three-month follow-up revealed ischemia in stress electrocardiogram in two patients (3.8%) in group 1 and in 2 patients (2.9%) in group 2. Coronary angiograms confirmed the stress ECG findings. There was one (1.4%) redo operation in group 2 and two (3.8%) in group 1. CONCLUSIONS: Both techniques are equal efficient. Even though time of operation is longer in patients receiving less invasive procedure, intensive care unit stay and hospitalization is exactly as long. Patients receiving minimally invasive surgery bleed less and have less pain early postoperatively.

Minimally invasive parasternal approach to tricuspid valve avoids repeat sternotomy.

We report the case of a 68-year-old patient with severe tricuspid regurgitation who had previously undergone aortic valve replacement and right coronary artery bypass. We performed tricuspid valvuloplasty via the right parasternal route in order to reduce surgical trauma by avoiding resternotomy, trauma to the venous graft, and bleeding due to dissection of old adhesions. The patient's postoperative course was uneventful, and he was discharged home on the 7th postoperative day.

[Evaluation of cases of off-pump CABG with mid-sternotomy].

Off-pump CABG was utilized on patients who had multivessel coronary artery disease and other organ diseases. A total of 79 patients who underwent off-pump CABG were evaluated. Of these, 66 suffered from OMI and AP, 4 form AP, 6 from u-AP, and 3 from AMI. LITA was used in 75 cases, RA in 48, GEA in 45, RITA in 13, IEA in 3, and SVG in 38. Revascularization was performed at # 2 in 3 cases, # 3 in 11, 4 PD in 37, 4 PL in # 7 or # 8 in 79, # 9 in 27, # 12 in 51, and # 14 in 17. A time of 10.3 min was spent on LAD revascularization, 9.8 min on D 1, 10.2 min on Cx, anf 11.5 on RCA. Seven patients were transferred to on-pump beating CABG because of hemodynamic instability. One patients suffered postoperative CVA, and 2 had wound infection. Complete revasculization was accomplished in 78 patients, and hospital death was not reported.

[Early and long-term results of treatment for infected deep sternotomy wounds].

A retrospective study and follow-up was undertaken to determine the optimal treatment of poststernotomy wound infections. Between January 1990 and April 2000 mediastinitis developed in 62 patients following 7458 heart operations (0.83%). Median age of 50 males and 12 females was 59.1 +/- 9.1 years (27-77). Mediastinal infections occurred within 14.2 +/- 10.9 days (3-90) following cardiac surgery. Most common symptoms and clinical findings were purulent wound drainage or dehiscence (50%), sternal instability (46.7%) and fever (35.5%). Most commonly isolated pathogens were Staphylococcus aureus and coagulase-negative Staphylococci which alone or together with other Gram-positive bacteria caused nearly 70% of all infections. Following the exploration and radical debridement, the wounds in two patients were left to heal by open granulation, 26 patients were initially treated by closed mediastinal suction--or irrigation, and 43 patients were treated with muscle and/or omental flap transposition (34 primarily, 9 following the failure of other methods). Recurrence of infections occurred in 16 patients: 10 from the "closed treatment" group (38.5%) and 6 from the "soft tissue flap" group (14%). Nine patients died during the hospital stay. The mortality rate was 15.4% following the closed method (4/26) and 14.7% following the treatment with flap reconstructions (5/34). There were 6 late deaths, non-related to recurrent infection. Healed wounds were obtained in 96.2% of all patients. About one third of patients noted continuous or intermittent chest pain or discomfort in the closed and the soft tissue flap transposition group. 22.6% of patients claimed sternal instability and 9.7% shoulder weakness--each of them underwent muscle and/or omental flap closure. Abdominal hernias or bulges were present in 4 patients (12.9%) following the use of abdominal flap for wound reconstruction. These results suggest that early debridement and closed method would be successful when employed soon after cardiac surgery. When reexploration is delayed for any reason or obvious extensive involvement of bone or cartilage is present, the wound should be reopened, debrided and treated with muscle and/or omental flaps. Patients in whom closed method fails could probably treated with soft tissue flap transposition soon after the reoperation. Long-term results of closed mediastinal drainage or lavage and flap closure are favourable to open granulation technique regarding wound healing and elimination of infection.

Chronic osteomyelitis after sternotomy.

Two patients with chronic sternal osteomyelitis after an initially uncomplicated coronary artery bypass grafting (CABG) operation are described. Chronic osteomyelitis, caused in both cases by Pseudomonas aeruginosa, occurred six and four months after CABG respectively. Because chronic infection failed to respond to local wound care and medical therapy, more radical treatment was needed. Steel wires were removed and surgical debridement was performed. In one patient, an additional omental transposition was performed. In both cases radical debridement in combination with antibiotics successfully eradicated the infection.
