  • APPLICATION OF ONESTAGE ARTERIOVENOUS SHUNT TO CIRCULATION RECONSTRUCTION FOR EXTENSIVE ARTERIAL ISCHEMIC DISEASE OF LOWER EXTREMITIES

    Objective To investigate the clinical effect of the one-stage arteriovenous shunt on the extensive arterial ischemic disease of the lower extremities. Methods The one-stage arteriovenous shunts in the lower extremities were applied to 90 patients with extensive arterial ischemic diseases, including arterial occlusive disease (AODs,62 patients) and thromboangiitis obliterans (TAOs,28 patients). By the retrospective analysis on the clinical materials and the follow-up of the postoperative patients, the immediate and the longterm surgical outcomes were summarized. Results During the hospitalization, 88 patients achieved a remarkable surgical effectiveness, with an immediate surgical effectiveness rate of 97.7% (88/90), but 2 patients failed in the operation and had to undergo amputation of the lower limb. Of the 72 patients who were followed up for 0.5-5 years after the arteriovenous shunt operation, 64 could have a sufficient blood supply to the lower extremities, with a longterm effectiveness rate of 88.9% (64/72); however, 8 patients had to undergo transplantation of the greater omentum or amputation of the lower limb. Conclusion The one-stage arteriovenous shunt performedon the lower extremities for an extensive arterial ischemic disease is a simpler and more effective surgical protocol for reconstruction of the circulation of the patient who is not suitable for the operation of arterial bypass.

  • Surgical Treatment of Primary Deep Venous Valvular incompetence of Lower Limb

    Objective To evaluate the surgical effects of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins stripping on primary deep venous valvular incompetence of the lower limb.Methods Seventy-eight patients (92 limbs) with primary deep venous valvular incompetence of the lower limbs received the operations of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins from 1997 to 2004. There were 65 males and 13 females, and their ages ranged from 32 years to 72 years (mean age of 52.5 years). The valvular reflux grades of these 92 limbs varied from Ⅲ to Ⅳ according to Kistner’s standard. A sleeve made from the stripped great saphenous vein was used in the indirect loop valvuloplasty of the superficial femoral vein. The early results of surgery were retrospectively analyzed. Results Pre-operative symptoms, such as edema, ulceration, pigmentation and heavy feeling of the performed limbs disappeared or were remarkably improved in 65 cases (76 limbs) after operation. Eight cases (10 limbs) had alleviative symptoms compared with pre-operative ones. Meanwhile, no improvement of symptoms was observed in 3 patients (4 limbs). Acute ilio-femoral vein thrombosis occurred in 2 patients (2 limbs), which manifested as more servious edema of the lower limbs than those before operation. The overall effective rate of surgery was 93.5%(86/92), and the complications rate was 2.2% (2/92). Conclusion Indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose vein stripping is an effective and convenient way to correct the primary deep venous valvular incompetence of the lower limb. The surgical indications of this disease should be emphasized strictly to assure the good outcomes.
