Clinical Study On Surgical Treatment For Critical Limb Ischemia

Many diseases can result in limb ischemia, such as arterial occlusion, critical arteriovenous fistula, aneurism and so on. Of those diseases, arterial occlusion is the common cause of limb ischemia. Regarding the limb arterial occlusion, arteries in lower limb are easier to be occluded than in upper limb, leading to critical leg ischemia. In this study, we focus on the surgical management of critical lower limb ischemia.Critical limb ischemia (CLI) is a common problem. It is defined as chronic or acute on chronic ischemia that endangers the whole or part of a leg. This is a clinical definition which includes ischemic rest pain of more than 2 weeks duration, ischemic ulceration, or gangrene. Rest pain, ulceration and gangrene are often considered together with critical limb ischemia. Its incidence is estimated to be between 50 and 100 cases per 100.000 populations per year. Lower extremity arteriosclerosis obliterans (ASO) frequently results from arteriosclerosis, diabetes mellitus and thromboangitis obliterans, in which the diabetes mellitus and arteriosclerosis are the common causes .Thromboangitis obliterans often occurs in the population of cold place. Arteriosclerosis can happen in any arteries of lower extremity in both diabetic and hypertention patients, and cause multilevel lower limb arterial occlusive disease, even amputation.Arteriosclerosis is the major cause of lower extremity arteriosclerosis obliterans...
