Leriche syndrome, also known as aortoiliac occlusive disease, is caused by atherosclerotic occlusive stenotic disease of the abdominal aorta and iliac arteries, with symptoms of proximal claudication. The hallmark triad of symptoms first reported by René Leriche for whom the syndrome bears his name is erectile dysfunction in males; diminished pulses; and claudication of thighs, hips, or buttocks.
Unknown; however, peripheral artery disease (PAD) increases with advancing age.
- Prevalence is unknown: 5–10% of patients with PAD
- Unique triad of symptoms (erectile dysfunction in males, diminished pulses, and claudication of thighs) appears in younger patients between 40 and 60 years, which are younger than for general PAD patients (1).
- Appears to be more common in males than females
Etiology and Pathophysiology
- Most common etiology is occlusive plaque in aortoiliac arteries. Cigarette smoking and hypercholesterolemia are two risk factors seen most commonly in patients with occlusive disease.
- Less likely to be associated with diabetes than typical patterns of PAD
- Main factors contributing to occlusive disease include arterial wall damage by hypertension, nicotine, lipid accumulation leading to plaque formation, and development of atheroma.
- A rare cause is Takayasu disease, which is a nonspecific arteritis that can lead to occlusive disease of the aorta.
