Takayasu arteritis (TA) is an inflammatory vascular disease which may present as aortic pseudoaneurysms, 1 intramural hematomas (IMH), 2,3 and coronary ostial stenoses. 4 We present images of a patient with TA who presented with syncope and what appeared to be an IMH of the ascending aorta.A 62-year-old female presented with a syncopal episode, and was noted on echocardiography to have moderate aortic regurgitation, a moderate pericardial effusion, and thickening of the ascending aorta without a dissection flap suggestive of an IMH. A computed tomography (CT) angiogram showed what appeared to be hematoma in the ascending aorta consistent with an IMH (Figure 1).At the time of surgery, cardiopulmonary bypass (CPB) was established with aortic and bicaval cannulation. Following cardioplegic arrest with antegrade, crystalloid cardioplegia, the ascending aorta was transected. No hematoma was found but the aorta appeared thickened and fibrotic (Figure 2A, B, and D). The right coronary aortic valve leaflet was thickened and retracted. An ascending aorta and hemi-arch replacement with a #30 Hemashield Dacron graft was performed, during a 33-minute period of circulatory arrest at 20°C. The aortic valve was replaced with a #19 ATS mechanical heart valve prosthesis (Medtronic, Minneapolis, MN). The total crossclamp time was 66 min and the CPB time was 160 min. The patient tolerated the procedure well and had an uncomplicated postoperative course. The gross pathology revealed a thickened, fibrotic aorta (Figure 2D). Microscopic sections showed both acute inflammation with polymorphonuclear neutrophils and chronic inflammation with lymphocytes and multinucleated giant cells. The aortic valve had changes consistent with myxomatous degeneration.A follow-up CT angiogram 6 years following the surgery showed no further progression of TA in the arch or descending aorta (Figure 3).During the follow-up, the patient was placed on steroid therapy.
