Infrarenal Abdominal Aortic Dissections

Abstract

Two cases of limited infrarenal abdominal aortic dissection are reported. One patient was treated successfully with medical therapy alone, which resulted in complete resolu tion of symptoms and obliteration of the dissection. The second patient continued to have pain and eventually required aortic graft replacement. Abdominal aortic dissection may be an entity different from thoracic aortic dissection.

Dissecting Aneurysm of the Infrarenal Abdominal Aorta: Report of a Case

“…13 Medical therapy is the initial treatment of choice when the patient is stabilized and the dissection has been identified. 1 For patients with persistent pain, a recurrent or progressive dissection, arterial insufficiency, and post-dissection aneurysmal development, surgical treatment is appropiate. A resection of the diseased segment with prosthetic graft replacement is reported to give the best results.…”

“…3 The wall of the abdominal aorta differs from that of the thoracic aorta, as it is avascular and thus much more prone to atherosclerotic lesions and aneurysmal dilatation than to dissection. 1 However, the factors predisposing to the development of an abdominal aortic A B the dissection can be identified only on a lateral view. 3 In the present case, digital subtraction angiography failed to reveal the intimal flap on an anteroposterior view.…”

“…Including the first reference to abdominal aortic dissection by Shekelton in 1822, Raymond et al have collected only about 70 cases having been reported to date. 1 We herein report a case of aortic dissection with aneurysmal dilatation (dissecting aneurysm) of the infrarenal abdominal aorta in a female patient who was 61 years old, and also discuss the diagnostic and therapeutic management of this rare disorder.…”
