ABSTRACT

Bypass grafting from the ascending thoracic aorta to the common iliac artery was performed to manage proximal hypertension in a patient with atypical coarctation of the thoracic aorta. The patient's history was significant for an acute aortic thrombosis at the level of the diaphragm for which she underwent an axillo-bifemoral bypass grafting as an emergency operation. Although she was doing well following the initial bypass grafting, the second bypass grafting was required to treat proximal hypertension refractory to medical management. The axillo-femoral bypass graft had a smaller diameter and a longer subcutaneous distance, and the blood supply to the abdominal viscera may have been insufficient. The proximal hypertension was well controlled following ascending thoracic aorta to common iliac bypass, because the diameter (16mm) of the graft is larger than that of the axillo-bifemoral bypass graft (8mm).

ABSTRACT

Between December of 1989 and May of 1993, 7 of 338 patients (2.1%) who underwent median sternotomy for cardiac operations developed mediastinitis. All of these infections caused by Staphylococcus species. Six of seven patients with mediastinitis were successfully treated with debridement, irrigation and omental transposition into the mediastinum. Between December of 1989 and May of 1992, sterile bone wax was used as a hemostatic agent in 233 of these patients. Between June of 1992 and May of 1993 an argon beam coagulator was used in place of bone wax in 105 patients. The incidence of mediastinitis significantly differed in relation to whether patients received bone wax or not (7 of 233 patients who did (3.0%) versus none in 105 patients who did not (0%) <i>p</i><0.01). We conclude from this study that bone wax may be a promoting agent in postoperative mediastinitis, so the routine use of bone wax should be reconsidered.

ABSTRACT

An emergency percutaneous cardiopulmonary support system (PCPS) was employed 11 arrest victims (5 males, 6 females; mean age 59.3 years) refractory to conventional resuscitation measures. Cardiac operation was subsequently performed in two patients and coronary angioplasty in two. The 7 other patients continued on cardiopulmonary support by PCPS after successful resuscitation. Duration of support was 10.5±9.1 (mean±S. D.) hours, the flow rate was 2.5±0.7<i>l</i>/min, and PCPS was applied 5-70min (mean, 24.9min) following the onset of cardiac arrest. The entire intraluminal surface of PCPS device had been heparin coated, activated coagulation time was maintained about 150 seconds, with or without minimal systemically administered heparin. Seven of 11 patients (63.6%) were successfully weaned from the PCPS. The early survival (<30 days) was 6 patients (54.5%), and late survival was 4 patients (36.4%). We conclude that PCPS can improve survival in patient unresponsive to conventional resuscitation when instituted soon after cardiac arrest.
