How should arteriosclerosis obliterans be treated?

summary

Arteriosclerosis obliterans is a disease in which atherosclerotic lesions involve peripheral arteries and cause chronic occlusion. Most of them were found in large and medium-sized arteries at the lower end of abdominal aorta. As a result of atherosclerotic plaque and its internal bleeding or plaque rupture, leading to secondary thrombosis and gradually produce lumen stenosis or occlusion, leading to limb ischemia and other clinical manifestations. How should arteriosclerosis obliterans be treated? Next, I'd like to share my views with you.

How should arteriosclerosis obliterans be treated?

General treatment: limit physical activity, keep the affected limb 20-30 below the level when lying in bed ° Slightly sagging position, and avoid direct heating; Quit smoking (smoking can cause vasospasm); Regular exercise should be done: the patient should walk under guidance to the distance causing claudication pain, but stop walking and rest until the symptoms are relieved. Then, walk again, exercise time is about 20-30 minutes.

Vasodilators: whether these drugs are effective for this disease remains controversial. In some cases, the decrease of arterial pressure and collateral blood flow or the diversion of blood flow to the healthy area of the proximal side of the lesion may reduce the perfusion pressure of the distal affected limb and aggravate the ischemic damage. Recently, oral pentoxifylline (400 mg, 3 times a day) was proposed to prolong the exercise time of the affected limb, increase the deformability of red blood cells and reduce blood viscosity.

Surgical treatment: in view of the segmental lesions, and mostly in large and medium-sized arteries, so about 80% of patients can be treated by surgery. The operation is suitable for patients with severe resting pain, progressive aggravation of symptoms and possibility of ulcer or gangrene. Lumbar sympathectomy can be used as an auxiliary surgical treatment to increase the skin blood flow of affected limb and promote the healing of skin ulcer. Most of the patients were treated with artificial blood vessel or great saphenous vein bypass grafting, or endarterectomy to dredge the blood flow to the affected limb.

matters needing attention

Diet should avoid thick taste. Staple food should be thick and thin, avoid alcohol, tobacco, strong tea and coffee. Obese people should cooperate with the treatment of weight loss, and exercise properly, so as to facilitate the movement of Qi and blood, such as Qigong, Taijiquan, aerobics and other activities. Usually should pay attention to keep warm, especially to avoid limb trauma infection, otherwise small trauma will cause limb gangrene.
