The mortality and morbidity associated with surgery for aortic root abscess is reportedly high. This is a review of our experience with radical resection of the abscess and reconstruction of the left ventricular outflow tract with pericardium. ⋯ Radical resection of aortic root abscess and reconstruction of the left ventricular outflow tract with pericardium is an effective method to eradicate the infection. These patients appear to have a relatively high risk of recurrent endocarditis.

Hemostasis is a significant problem in aortic surgery requiring profoundly hypothermic techniques. Aprotinin, a serine protease inhibitor, reduces blood loss in high-risk coronary and valve surgery, but its use in profound hypothermia is controversial. ⋯ This data does not support the adverse effect of aprotinin upon early survival. Although early reports were of concern, the role of aprotinin as an adjunct to hemostasis requires further investigation.

From October 1973 to December 1995, 251 patients (204 male, 47 female) aged from 10 to 75 years (mean: 46.6 +/- 15) underwent an ascending aortic replacement with a composite graft for: dystrophic aneurysm (AN), 168 cases (66.9%); chronic dissection (CD), 36 cases (14%); and type A acute dissection (AD), 48 cases (19.1%). Fifty-one patients (20.3%) suffered from Marfan's disease (25 AN, 17 AD, 9 CD). Thirty-seven patients (14.7%) had undergone a previous cardiac or aortic operation. The ascending aortic replacement was extended to the transverse arch in 31 patients (12.3%). A mechanical valve was used in 233 patients (92.8%). The classic "Bentall" technique was used in 87 patients (34.6%), the "button" technique in 121 patients (48.2%), the "Cabrol" technique in 26 patients (10.3%) and a "mixed" technique in 17 patients (6.2%). ⋯ Ascending aortic replacement with a composite graft is a safe procedure, especially when performed electively in patients with dystrophic aneurysm or Marfan's disease. The technique of coronary reimplantation has a significant influence of the long-term results, with the reimplantation of choice being the "button" technique. The "Cabrol" technique must be used when the "button" or the "Bentall" reimplantation is not feasible.
