目的:探讨静脉动脉化手术治疗下肢血栓闭塞性脉管炎的治疗经验。方法:对31例下肢动脉广泛闭塞的血栓闭塞性脉管炎患者行静脉动脉化手术,严密观察手术前后肢体症状和体征的变化,总结治疗经验。结果:术后患肢症状和体征均明显改善,长期随访5月至8年(平均3.5±0.5年)转流静脉通畅,患肢血运均良好,均未行截肢手术。结论:静脉动脉化手术可以改善肢体远端血供,是治疗下肢动脉广泛闭塞较有效的方法。
Objective: To explore the experience of treatment of lower extremity thromboangiitis obliterans by venous arterial surgery. Methods: Thirty-one patients with thromboangiitis obliterans with extensive occlusion of the lower extremity underwent venous arterial surgery. The changes of limb symptoms and signs before and after operation were observed closely and the treatment experience was summarized. Results: The symptoms and signs of the affected limbs were significantly improved. Long-term follow-up of 5 to 8 years (average 3.5 ± 0.5 years) showed that the bypass veins were unobstructed and limb blood flow was good. No amputation was performed. Conclusion: Intravenous arterial surgery can improve distal limb blood supply, which is a more effective method for treating extensive occlusion of lower extremity arteries.
