RESUMO
To survey the results of operative outcome for aortic dissection. A retrospective study on 46 patients, admitted for operation in Shahid Madani Heart Hospital in Tabriz, Iran from 1994-2003. A questionnaire was used for collecting data. Statistical analysis was performed and was carried out through a descriptive statistical methods. We included 30 males [65%] and 16 females [35%]. Seven [15.2%] died in the operating room before surgery, while 39 patients [59% male and 41% female] underwent surgery. The mean age of patients was 48.9 +/- 2.3 years old. Pre-operative diagnosis was carried out by transesophageal echocardiography and angiography. All patients were operated in an emergency situation. In 42% of patients aortic valve replacement [AVR] with ascending aorta was replaced. In 24% only the ascending aorta was replaced, and in 10% the aortic valve was repaired with acute aortic dissection. In 10% of patients, the ascending aorta with aortic arch was replaced. Four patients [14%] had distal aortic dissection and replacement. Major complications were hemorrhage [31%] and respiratory failure [13.8%]. A total of 20.7% died in hospital, and only 21 patients [45.5%] could be followed for 10 years. Acute aortic dissection is a fatal disease. With early diagnosis and surgical intervention, we can save approximately 75% of patients with very good functional class and survival in the mid term
