What is leriche syndrome?

Leriche syndrome, also known as aortoiliac occlusive disease or Leriche's syndrome, is a rare condition that occurs when there is a blockage in the abdominal aorta (the largest artery in the body) where it divides into the two iliac arteries that supply blood to the legs, pelvis and lower abdomen. This blockage can lead to reduced blood flow to the lower extremities.

Symptoms of Leriche syndrome include lower back pain, thigh and buttock pain, leg pain, weakness, and numbness. Sexual dysfunction in males may also occur due to inadequate blood flow to the penile arteries.

The cause of Leriche syndrome is usually atherosclerosis, a buildup of fatty plaques in the arteries. Other conditions that increase the risk of developing Leriche syndrome include smoking, high blood pressure, high cholesterol, and diabetes.

Treatment options for Leriche syndrome include lifestyle modifications such as quitting smoking, controlling blood pressure and cholesterol, and increasing physical activity. Medications such as blood thinners and medications to improve blood flow may also be prescribed. In severe cases, surgery may be necessary to bypass the blocked area or remove the blockage.
