Isolated dissection of the abdominal aorta: Clinical presentation and therapeutic options

Abstract

Although the natural history of isolated abdominal aortic dissection has not been well defined, our experience adds to the understanding of this rare process. Because aneurysmal degeneration can occur, close surveillance is indicated if definitive treatment is not used initially. Patients with ischemic symptoms and those with intractable pain need intervention, the nature of which should be based on risk profile and aortoiliac anatomy.

Endovascular treatment of isolated abdominal aortic dissection and postoperative aortic remodeling

“…The choice of treatment was decided according to the patients' symptoms, signs, and the morphologic characteristics from the CT findings. Patients with following characteristics were indicated for endovascular treatment: (1) signs of aortic rupture, (2) visceral, renal, or limb ischemia, (3) persistent abdominal pain not relieved by observation treatment, (4) aortic diameter >3 cm, 8 and (5) a suprarenal IAAD. 9 Endovascular treatment mainly included placement of an aortic tube graft or bifurcated stent graft in the abdominal aortic true lumen.…”

Spontaneous abdominal aortic dissection treated by endovascular stent grafting: Report of a case

“…6 Because of its rarity, the natural course of a spontaneous abdominal aortic dissection is unknown, and the appropriate management has not been well defi ned. [7][8][9] In 2002, Mozes et al reported one case of infrarenal aortic dissection and reviewed another 41 previously published cases. 1 Eighty percent of the 42 patients were symptomatic including abdominal or back pain (48%) and acute lower extremity ischemia (17%).…”

Imaging of aortic abnormalities with contrast-enhanced ultrasound. A pictorial comparison with CT

“…Isolated abdominal aortic dissections are rare and are much less common than abdominal dissection associated with thoracic aortic dissection [30]. As with AAA, hypertension is believed to be a major risk factor for aortic dissection [31].…”
