Endovascular treatment of stenoses in a pediatric patient with incomplete aortic duplication, mesenteric ischemia, and renovascular hypertension.

Variations in abdominal aortic anatomy may have significant implications in various surgical procedures. We report here a pediatric patient with symptoms of chronic mesenteric ischemia, labile hypertension, and lower extremity claudication. Angiography revealed a partially duplicated aorta with the anterior aorta containing the splanchnic and renal arteries and the posterior segment perfusing the lower extremities. She was successfully treated with balloon angioplasty of two focal stenoses and is normotensive without abdominal symptoms at 1-year follow-up. To our knowledge, this is the first report of a successful endovascular intervention in a partially duplicated aorta.
