[Smooth muscle cell apoptosis in aneurysmal aortic lesion in the light of surgical treatment results].

Aortic aneurysm is a polyethiologic disease associated with high disability and perioperative mortality rate. The evolution of ethiopathogenesis of aortic aneurysm development is considered in the article. The findings of recent worldwide studies on immune status impact on the disease progress and the postoperative period are presented. All studies showed that 25% of patients had immune status disturbances accompanied by changes in the hemostasis system and high apoptosis index in blood serum and aneurysm tissue. Variants of clinical course of different aortic aneurysm forms and perioperative managements of patients aimed at prevention of possible complications are highlighted.
