arterial reconstruction

The purpose of arterial reconstruction is to increase limb blood supply and reconstruct arterial blood flow channels, and to improve the consequences of ischemia. Treatment of diseases: hamartoma, small sweat gland, vascular hamartoma, diffuse mesothelioma, localized mesothelioma Indication Arterial occlusion. Contraindications Preoperative preparation Surgical procedure There are two surgical methods: 1 bypass bypass, suitable for occlusion of the main artery, but there are still smooth arterial access in the proximal and distal occlusion of the artery; for example, only the radial artery occlusion, can be used as a femoral artery, bypass artery bypass. 2 thrombectomy and endarterectomy, suitable for short-term arterial obstruction using the endometrial stripper, or open the arterial wall under direct vision, the thickened endometrium together with the thrombus, and then suture the arterial wall incision. For extensive arterial occlusion, ie, the distal three arteries of the radial artery have been occluded, the following procedures can be tried: 1 large omentum transplantation: the principle of surgery is to remove the omentum after the whole piece is cut and extended, the right movement and vein of the gastric retina are respectively matched with the femoral artery and saphenous vein, and the subcutaneous tunnel is pulled to the calf and deep fascia. Fixation, by establishing a collateral circulation to provide blood supply to the ischemic tissue. 2 stage venous and venous bypass: the principle is to first establish artificial arteriovenous fistula in the affected limb, intending to use the intravenous route to reverse perfusion to provide arterial blood for severely ischemic limbs; 4-6 months later, re-surgery ligation proximal vein. At present, although there are reports in the literature that different degrees of success have been achieved, whether the blood flow through intravenous reverse perfusion can meet the basic problems of tissue nutrition exchange needs to be further clarified; and the increase of venous hypertension and blood flow to the heart may cause serious consequences. Therefore, this method should be tried after careful consideration.
