中晚期肺癌动脉聚乙烯醇栓塞的疗效分析

Evaluation of the therapeutic effect of arterial PVA embolization for mid and advanced pulmonary carcinoma

目的探讨聚乙烯醇(PVA)颗粒动脉灌注栓塞治疗晚期支气管肺癌的近期疗效。方法对31例中晚期肺癌患者进行选择性支气管或肋间动脉造影,造影确定有富肿瘤血供动脉后行灌注栓塞术,先行将5-FU、阿霉素(THP)、顺铂灌注再用PVA颗粒经导管栓塞患侧供血动脉。结果31例患者中供血动脉以支气管动脉为主者21例,以肋间动脉为主者10例。治疗后临床症状改善率100%,且无严重并发症,有效率为80.6%(25/31)。结论PVA颗粒选择性栓塞治疗中晚期支气管肺癌具有较好的临床疗效,安全性高且并发症较少。

Objective To explore the therapeutic effect of arterial PVA perfusion embolization in o treating mid and advanced pulmonary carcinoma. Methods Thirty-one patients with pulmonary carcinoma in the mid or late stage diagnosed pathologically underwent selective angiographic studies of the bronchial arteries and intercostal arteries to provide information of the hypervascular feeding vessels, and then performed the perfusion with 5-FU, THP, DDP; followed by PVA grain embolization under fluoroscopic control. Results Abnormal tumor feeding vessels of pulmonary carcinoma were found deriving from bromehial arteries in 21 cases, and from intercostal arteries in 10. After arterial infusion of chemotherapy combined with embolization of PVA,alleviation of clinical symptoms was observed in all 31 cases （100%）without severe complication, The total effectiveness （CR plus PR） reached 80.6% （25/31 ）. Conclusions Arterial embolization of PVA is safe, effective with less complication for treatment of mid or advanced pulmonary carcinoma. （J Intervent Radiol, 2006, 15： 402-404）
