Abstract
Objective: To discuss the effectiveness of femoral-femoral artery bypass grafting combined with transverse tibial bone transporting in treatment of lower extremity arteriosclerosis obliterans (ASO) or combined with diabetic foot. Methods: Between March 2014 and June 2016, 9 patients with lower extremity ASO or combined with diabetic feet were treated with femoral-femoral artery bypass grafting and transverse tibial bone transporting. All patients were male, aged from 63 to 82 years with an average of 74.2 years. The disease duration of ASO was 1.5-22.0 months (mean, 10.5 months). All cases were severe unilateral iliac arterial occlusion, including 5 cases of the left side and 4 cases of the right side. There were 7 cases with superficial femoral and/or infrapopliteal artery disease. There were 7 cases of ASO and 2 cases of ASO combined with diabetic foot (Wagner grade 4); all the ASO were grade Ⅳ according to Fontaine criteria. All patients had rest pain before operation, and the ankle brachial index was 0.24±0.12. In femoral-femoral artery bypass grafting operations, artificial blood vessels were used in 7 cases and autologous saphenous vein were used in the other 2 cases. The tibial bone transverse transporting began on the 8th day after operation by 1 mm per day and once per 6 hours; after transported for 2-3 weeks, it was moved back. The whole course of treatment was 10-14 weeks. Results: The incision of tibial bone transverse transporting was necrotic in 1 case, and healed after dressing change. There was no obvious complication at the orifice of the needle. The other patients had no incision complication. The granulation tissue of foot wound was growing quickly after tibial bone transverse transporting, and the wound was reduced after 2-3 weeks. All the 9 patients were followed up 12-32 months (mean, 19 months). The ankle brachial index was 0.67±0.09 at 2 months postoperatively, which was significantly higher than that before operation ( t=17.510, P=0.032). All the feet ulcer wounds healed and the healing time was 6.7-9.4 weeks (mean, 7.7 weeks). During follow-up, color Doppler ultrasound or CT examination revealed grafted blood vessel patency. The external fixator was removed at 12-14 weeks after operation. One case died of sudden myocardial infarction at 14 months after operation, and there was no lymphatic leakage. The patency rate of femoral-femoral bypass was 100% at 1 year after operation. The tibial transverse bone grafting healed with tibia at 4-6 months after operation. At last follow-up, the effective rate was 100%. Conclusion: Femoral-femoral artery bypass grafting combined with transverse tibial bone transporting is an effective method in the treatment of lower extremity ASO or combined with diabetic foot.
