Aorto-Iliac Occlusive Disease

TREATMENTS

What is aorto-iliac occlusive disease?

Aortoiliac occlusive disease, also known as  Leriche’s syndrome is an advanced and late complication of atherosclerotic vascular disease.it is a chronic disease resulting from progressive atherosclerotic and thrombotic accumulation. Patients can present with symptoms ranging from life-limiting claudication to limb-threatening ischemia requiring amputation.

Signs & Symptoms:

  • Claudication of buttocks and thighs.
  • Decreased or absent femoral pulses.
  • Erectile dysfunction.

Diagnosis:

  • Color Doppler.
  • CT angiography.
  • Conventional angiography

Role Of Interventional Radiology

While Indications for intervention include life-limiting claudication, rest pain and tissue loss, the goal of treatment involves re-establishment of inflow to the lower extremities and pelvis.

 

Angioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty (PTA) is employed in such a case. It is a  minimally invasive procedure to widen narrowed or obstructed arteries or veins. A deflated balloon attached to a balloon catheter is passed over a guide-wire into the vessel when the narrowed part is reached it is inflated to a fixed size. The balloon expands the blood vessel and the surrounding muscular wall, allowing an improved blood flow. The balloon is then deflated and withdrawn. A stent may be placed to assure patency. 
It is safe and well tolerated procedure with good results.
