Surgical treatment of acute type A dissecting aneurysm, with preservation of the native aortic valve and use of biologic glue. Follow-up to 6 years.

We present an analysis of 59 patients operated on between 1983 and 1987 for acute type A dissecting aneurysm with aortic valve insufficiency. The ascending aorta was replaced with a Dacron tube, the layers of the dissection were unified with gelatin-resorcine-formaldehyde glue, and the natural aortic valve was preserved. Follow-up every 6 months was subject to actuarial analysis.
