1. Aneurysm:15th March 19822. CADA: 28th October 19833. AADA: 22nd May 1989


METHODS: From March 1982 to March 2012, 179 patients (112 males, age 56.4 ± 12.6 years) received an ET procedure (91 aneurysms, 88 dissections (47 acute)). The cerebral protection was done either by deep (till 1999) or moderate hypothermic circulatory arrest and selective antegrade cerebral perfusion (SACP, after 1999).RESULTS: Among AADA Patients, the 30-day mortality during the first-stage operation was 32% (15/47)Peri-operative stroke was 17% (n = 8/47). Postoperative recurrent nerve palsy was present in 13% (8/47).

The second stage completion is inevitable!

Aortic arch surgery doesn‘t always result in death !

Intra-operative BleedingMyocardial failure (?Long X-clamp time)Multi-organ failure
