Abstract
Early thrombosed aortic dissection is a form of aortic dissection and includes the condition called aortic intramural hematoma. It was generally considered as surgical emergency. However, the optimal treatment strategy for acute type A intramural hematoma is becoming controversial after recent studies indicated more benign clinical course for this disease. We evaluated our strategy that integrated medical therapy, serial imaging, and timed surgery. We reviewed 34 consecutive patients who were admitted to our hospital for early thrombosed Stanford type A acute aortic dissection from 2006 to 2011. Medical therapy or timed surgery was offered on the basis of radiological findings. Emergency or urgent surgery was not considered for a hemodynamically stable patient unless the ascending aortic diameter was ≧50 mm or the thickness of the thrombosed false lumen was ≧10 mm. Follow-up computed tomography was performed to detect a potential progression to aortic dissection. During the average follow-up period of 24.3 months, there was no aortic dissection-related mortality. And aortic dissection-related event was not recorded in patients who had surgical repair; however, in patients who did not have surgery, 3 (8.8 %) surgical conversions were recorded due to aortic dissection progression during the follow-up period. Twenty-one patients (61.8 %) ultimately had surgical repair, and 13 patients (38.2 %) had complete medical therapy. The overall survival rate at 3 years was 86.5 %. Our strategy for the treatment of early thrombosed Stanford type A acute aortic dissection is reasonable, and the mid-term results were acceptable.
