Trans-catheter closure of a large aneurysm in coarctation of abdominal aorta

• Here, we are presenting a very rare case of coarctation of abdominal aorta where a transcatheter closure by a vascular plug of the feeding collateral to a large aneurysm has been done. To the best of our knowledge, this mode of therapy has never been described in persons with coarctation of abdominal aorta. • Aneurysms in patients with an abdominal coarctation are not well recognized. This is probably the only case being reported where transcatheter closure of the feeding vessel to the aneurysm has been successfully performed. • In this case, aneurysm was closed by a vascular plug only to prevent sudden rupture and death, and no attempt was made for stenting or dilatation of the atretic segment as the segment was long and no direct connection could be noted between upper and lower segments. The incidence of coarctation of the abdominal aorta is rare and the possibility of aneurysms in coarctation of the abdominal aorta is very rare compared to coarctation of the descending thoracic aorta. Thus, this case is being reported in view of the extreme rarity of the problem.
