Aortoiliac occlusive disease

The Leriche syndrome (named after the French surgeon René Leriche ) is a complete occlusion of the aorta distal to the outlet of the renal arteries, usually before the bifurcation into the iliac arteries. The reasons for this can hardening of the arteries (atherosclerosis ), arterial wall inflammation (vasculitis ) and blood clots be (thrombosis / embolism). In all cases there is a constriction at the level of the bifurcation of the abdominal aorta in the pelvic arteries. Depending on whether the circulatory disturbance occurs suddenly or develops slowly, it comes to cold legs, pain, impotence, and wasting.

Symptoms

In an acute closure leads to a reduced perfusion of the lower extremities, which goes with the typical symptoms after six P- " Pratt " hand in hand. These are:

Pain pulselessness pallor paresthesia paralysis prostration

Pain pulselessness pallor hearing loss paralysis shock

In chronic circulatory disturbance (usually in the context of atherosclerosis ) leads to disturbances of bladder and Rektumfunktion and it comes to erectile problems to the impotence.

Treatment

To avoid permanent damage to the less served areas, a therapy must be initiated as soon as possible. Depending on the severity of circulatory disorders are either catheter procedures ( angioplasty) or surgery (bypass or Y- prosthesis ) into consideration.

The sudden restoration of blood flow ( sog.Reperfusion ) a so-called syndrome Postischämie is possible, which must be treated.
