BACKGROUND: Acute aortic dissection is one of the most serious life-threatening conditions, with mortality during the first 48 hours reaching 50%.
AIM: To assess short and long-term effects as well as safety of surgical treatment of aortic dissection combined with aortic valve repair.
METHODS: The study group consisted of 57 patients (38 males, 19 females, mean age 47.9 +/- 13 years) with dissection of the ascending part of the aorta (type A aortic dissection) who underwent surgery in our institution between 1985 and 1999. Follow-up duration ranged from 2 to 16 years -- mean 6 years. Control transthoracic or transesophageal echocardiography was performed in 37 patients.
RESULTS: Early mortality was 21%. There were 12 perioperative deaths and 3 late non-cardiovascular deaths. Three patients underwent repeated surgery due to (1) aortic valve insufficiency, (2) pseudoaneurysm at the site of the anastomosis between proximal part of the vascular prosthesis and the aorta, and (3) fistula between aorta and right atrium.
CONCLUSIONS: Aortic dissection type A is more frequent in males than females. The main causative factor is hypertension. Early mortality is significantly higher in patients undergoing emergency surgery compared with elective procedures. Heart failure symptoms (NYHA class) improve postoperatively in the majority of patients. Aortic valve repair is effective and relatively safe, and is an alternative to the aortic valve replacement with coronary arteries reimplantation.
