摘要
目的观察了解经皮腔内血管成形术(PTA)在治疗下肢动脉闭塞症腘下段病变中的可行性和短期效果。方法选取4例下肢动脉硬化闭塞症患者,对其7支腘下动脉的15处病变进行PTA治疗,观察术中及术后患者的临床和血管造影表现,并对其中3例患者进行短期(<12个月)随访。结果PTA技术成功率60%(9/15),PTA后放置支架6枚;术后1例出现骨筋膜室综合征而截肢;术后6个月的血管通畅率50%(3/6),血管病变复发率38.5%(5/13);1例于术后9个月余截除第一趾。结论在明确病变远侧流出道情况下,经皮腘下动脉腔内血管成形术对于严重下肢缺血的患者具有肯定的近期疗效。
Objective To explore the feasibility and short-term outcome of percutaneous transluminal angioplasty （PTA） as a primary treatment modality for high-grade lesions of the infrapopliteal arteries in critical limb ischemia. Methods Four cases with 15 lesions in their infropopliteal arteries were treated with PTA, the symptoms, intraoperative and postoperative DSA characteristics were retrospectively analyzed. Short-term follow-up were obtained in 3 cases. Results The technical success rate related to procedure were 60%, and 6 stents were placed after infrapopliteal PTA. One case was suffered from amputation due to development of osteofascial compartment syndrome. The primary patency rate and recurrence rate of 6 months after procedure were 50% and 38.5%, respectively. The amputation was performed in 1 case about 9 months after procedure. Conclusion Patients with critical limb ischemia could be beneficial from PTA in infrapopliteal arteries if adequate outflow were observed in DSA.
