Acquired Infrarenal Abdominal Aortic Coarctation: Treatment with Percutaneous Self Expandable Stent

Abstract

Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic resonance angiography of abdominal aorta, iliac and femoral arteries revealed local stenosis of abdominal aorta below the renal arteries (80% of luminal diameter). The length of coarctation was 3 cm. The patient was scheduled for percutaneous aortoplasty and stent implantation. Nintinol self-expandable stent was implanted. At 9 months clinical follow up no signs or symptoms of stenosis or diminished blood flow in lower extremities were found. Self-expandable stent is effective, easy to implant, and has good adaptation to the wall of aorta and can be considered in such cases successfully.
