[Pathogenesis and prophylaxis of venous thromboembolic complications at large ventral hernias].

Overall 188 patients undergone surgical treatment due to large postoperative ventral hernias are analyzed. It is demonstrated that venous hemodynamics at these patients before surgery is characterized by disorders of "abdominal-caval pump" function due to anterior abdominal wall destruction and low mobility of diaphragm's cupula. The recovery of their functions is the key point in prophylaxis of thromboembolic complications.
