Abstract
Objective: Most previous reports on intramural hematoma of the aorta have focused on the initial episode. The purpose of this study was to clarify the long-term outcome of intramural hematoma of the aorta. Methods: Ninety-four cases of intramural hematoma of the aorta (41 type A and 53 type B) were reviewed. There were 69 male and 25 female patients, and their mean age was 66. 7 ± 8.7 years (range, 46-88 years). Results: Eleven (27%) of the patients with type A hematoma and 1 (2%) of the patients with type B hematoma underwent early surgical intervention. Others were treated medically, and the overall hospital mortality was 7% for patients with type versus 2% for patients with type B intramural hematomas of the aorta (P = .315). Twenty-three patients, 9 (22%) with type A and 14 (26%) with type B intramural hematomas of the aorta, underwent late surgical intervention during the follow-up period, and there were no hospital deaths. A total of 23 patients died during the follow-up period, including 6 of intramural hematoma of the aorta-related deaths (3 in the type A group and 3 in the type B group). The estimated freedom from intramural hematoma of the aorta-related events at 1 and 5 years was 70% ± 8% and 54% ± 11% for the type A group versus 73% ± 6% and 58% ± 8% for the type B group, respectively (P = .972). After excluding the nonintramural hematoma of the aorta-related deaths, the survival rates at 5 and 10 years were 80% ± 9% and 80% ± 9% for the type A group and 91% ± 8% and 81% ± 11% for the type B group (P = .211). Conclusions: Intramural hematoma of the aorta-related events occur equally in both types of intramural hematoma of the aorta. We recommend close follow-up for at least 5 years because most intramural hematoma of the aorta-related events occur during this period.
