What is Leriche Syndrome?

Leriche syndrome is a vascular disease characterized by obstruction or narrowing in the lower part of the aorta, leading to a blockage of blood flow to the pelvic and lower extremity regions. This condition is characterized by the occlusion of the terminal branches of the aorta that supply the arteries of the legs.

The most common cause of Leriche syndrome is atherosclerosis, which involves the accumulation of plaque on the walls of arteries. These plaques can narrow the inner surfaces of arteries, obstructing blood flow. Other causes may include vascular inflammation, fibromuscular dysplasia of the vessel walls, and emboli (clot particles).

Symptoms of Leriche syndrome may include:

• Pain and numbness in the hip, thigh, and calf regions
• Leg pain that increases with exercise (intermittent claudication)
• Sexual dysfunction
• Cold or pale skin
• Weak or absent pulses
• Non-healing leg wounds or ulcers

Methods used for the diagnosis of Leriche syndrome may include:

• Physical examination
• Doppler ultrasonography
• Computed tomography (CT) scan
• Magnetic resonance angiography (MRA)
• Angiography

The treatment of Leriche syndrome can vary based on the patient’s symptoms, the severity of the obstruction, and overall health. Treatment options may include:

Medical Treatment: Medications may be used to improve blood flow and alleviate symptoms.

Endovascular Interventions: Minimal invasive procedures, such as angioplasty and stent placement, can be performed to open the blockage.

Surgical Treatment: Surgical revascularization or bypass surgery may be necessary for severe obstructions.

Post-treatment care involves the patient’s recovery after surgical intervention. This process may include follow-up appointments, blood pressure monitoring, pain management, and adjusting the level of physical activity. Additionally, lifestyle changes and managing risk factors are crucial components of post-treatment care.
