[Prognosis of type A acute aortic dissection treated conservatively].
We examined 58 cases of type A acute aortic dissection treated from 2003 to 2005 in our hospital. Thirty-three patients were treated surgically and 25 patients were treated conservatively. Among the 25 patients treated conservatively, 13 patients had open false lumen, and were eligible for surgical therapy. Surgical therapy was abandoned however, for various reasons (stroke, advanced age, malignancy, renal disease, lung disease, or patient's reject). Thirteen patients (52%) treated conservatively died while only 1 patient (3%) treated surgically died. Patients with thrombosed false lumen had good prognosis while those with open false lumen or ischemic complication had poor prognosis. It is concluded that patients with thrombosed false lumen of type A acute aortic dissection could receive conservative therapy with surgical team's back up and close computed tomography (CT) follow up to detect recanalization and enlargement of the aorta.
