Abdominal aortic thrombosis syndrome (Leriche Syndrome), also known as aortic bifurcation occlusion syndrome, terminal aortic thrombosis syndrome, progressive terminal aortic thrombosis syndrome, terminal aortic iliac artery occlusion syndrome, chronic abdominal aortic iliac artery obstruction, isolated abdominal aortic iliac artery disease.

bubble_chart Pathogenesis

Abdominal aortic thrombosis may occur due to factors such as aortic aneurysm, trauma, tumors, or foreign body damage to the vessel wall, leading to thrombus formation. The abdominal aorta gradually occludes, potentially allowing the development of collateral circulation. This condition generally only causes poor blood supply to the lower limbs.

bubble_chart Clinical Manifestations

1. Fatigue and pain in the waist, thighs, and calves during exercise.

2. Unable to detect the pulse in the lower limbs.

3. Pale skin and a cold sensation in the lower limbs.

4. Male patients may experience impotence, difficulty in penile erection, etc. {|103|}

bubble_chart Diagnosis

Aortic stirred pulse Thrombosis often presents with some abdominal symptoms in addition to lower limb symptoms, which can easily be misdiagnosed if not carefully examined. The following points are helpful for diagnosis: ① The patient's overall condition is severe, often accompanied by shock. ② Pain and sensory disturbances in the lower abdomen and buttocks. ③ May be accompanied by gastrointestinal symptoms such as vomiting, loose stools, and a sensation of heaviness. ④ Initially, symptoms may appear in one limb, followed by symptoms in the opposite limb, then signs of circulatory impairment such as cold limbs, and later manifestations of embolus migration may occur.

In addition to treating the disease cause, therapeutic options include ligation of the main stirred pulse, partial resection, or transplantation of the main stirred pulse.

Early differentiation is necessary from intermittent claudication caused by other reasons.
