An infrarenal abdominal aortic coarctation

Abstract

We describe a case of infrarenal abdominal coarctation in a 44-year-old woman who presented with severe uncontrolled hypertension. She had no signs of lower limb ischemia with normal distal pulses. Electron beam tomography revealed abdominal aortic coarctation extending from the superior mesenteric artery to the inferior mesenteric artery with a diameter of 9 mm. Also, at the level of coarctation, the aortic branches including the renal arteries were in a serpentine shape.

“…The possible etiology may be developmental defects or a response to infection and inflammation. There may be associated Takayasu's arteritis, neurofibromatosis, and Williams's syndrome [1, 5, 13, 15]. In our series, four of the patients had acquired abdominal coarctation of aorta secondary to a localized atherosclerosis, with onset of the symptoms in middle age.…”

“…Abdominal aortic stenosis is extremely rare, with an overall incidence ratio of 1/62500 in an autopsy study [5]. It is often with occlusive diseases of the visceral and renal arteries in most of the cases [10–12].…”

“…Coarctation of the abdominal aorta is an uncommon disease in which different etiologies and treatment methods have been reported. There are a few life threatening sequelae of untreated disease, such as uncontrolled hypertension from chronic renin‐angiotensin activation, gastro‐intestinal tract ischemia, lower limb ischemia or emboli, renal failure, aneurysm rupture, cardiac hypertrophy, and arrhythmia [1–11].…”

Atypical infrarenal aortic coarctation

“…Infrarenal aortic agenesis, atresia, or coarctation is an extremely rare vascular anomaly with an overall occurrence of 1/62,500 or <0.002%. 2 First described by Quain in 1847, 3 aortic coarctation, the narrowing and tapering of the distal aorta, often leads to uncontrollable hypertension and peripheral vascular disease. 4 Although the etiology of this pathologic entity is unknown, it has been proposed that this syndrome is a result of improper fusion of the distal aortas during the first month of embryonic development.…”

Middle Aortic Syndrome: A Case Report and Review of the Literature

“…Natural bypass of the aortic constriction is accomplished by development of collateral network from branches of the subclavian, internal mammary, intercostals, superior mesenteric and axillary arteries, to the inferior mesenteric, lower intercostal and lumbar arteries, the inferior epigastric branches of the femoral arteries and the superior hemorrhoidal pathways via the marginal artery of Drummond and arc of Riolan [15].…”
