ABSTRACT
BACKGROUND:
The aim of the study was to evaluate operative and long-term results after acute type A aorta dissection (AAAD) operation, in which complete resection of all dissected aortic segments (curative repair) was achieved.METHODS:
Among 205 consecutive patients operated on between 2002 and 2014 because of AAAD were 88 patients (42.9%), in whom the dissection did not extend into the downstream aorta. The distal extension of the dissection ended before the origin of the innominate artery in 50 patients of the study cohort (56.8%) or extended throughout the arch, necessitating a total/subtotal arch replacement to achieve a curative distal repair in 38 remaining patients (43.2%). The aortic root was involved in 52 patients (59.1%) and was repaired using valve-sparing repair (31) or replacement with a valve composite graft (21). Combination of root and open arch surgery was reported in 46 patients (52.3%).RESULTS:
Thirty-day and in-hospital mortalities were 3.4% and 5.7%, respectively. Survival was estimated starting with the operation and was 81.9% ± 4.5% and 56.6% ± 8.7% at 5 and 10 years, respectively. No patient required reoperation on the aortic root and/or distal thoracoabdominal aorta; however 2 cardiac reoperations were unrelated to the primary surgical procedure. Moreover, the freedom of aortic and/or sudden/unknown death was 100%.CONCLUSIONS:
Curative aortic repair can be achieved in a relevant share of AAAD patients and is mostly limited by the distal extension of dissection. This kind of repair is advisable, whenever possible, because it can provide very low risk of aortic complications and/or reoperations over time.
