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

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 em. 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.
