A surgical treatment for frank rupture of acute type a small intramural hematoma
Abstract
A 71-year-old woman was admitted to the hospital due to cardiac tamponade. Computed tomography revealed that the diameter and wall thickness of the ascending aorta were 36 and 9 mm, respectively. An emergent ascending aortic replacement was performed uneventfully. The pathological findings indicated frank rupture of intramural hematoma.
The treatment of acute type A intramural hematoma (IMH) has been controversial. It is reported that initial medical treatment with blood pressure and pain control and repetitive imaging may be a reasonable option, particularly in the absence of aortic dilation (<50 mm) and IMH thickness <11 mm.1 A 71-year-old woman was admitted to the hospital due to cardiac tamponade. Computed tomography revealed that the diameter and wall thickness of the ascending aorta were 36 and 9 mm, respectively, indicating type A intramural hematoma (Figure 1A,B). An emergent ascending aortic replacement was performed, but it resulted in uneventful outcomes (Figure 1C–E). The pathological findings indicated frank rupture of intramural hematoma (Figure 1F). Acute type A small IMH is rare; however, physicians should be aware of this possible complication.
