目的　探讨布 加综合征下腔静脉病变类型与内支架选择的关系。方法　应用PTA及PTSA治疗BCS186例 ,术前应用彩色Doppler常规检查。选择内支架按以下要求 :①内支架直径应超过下腔静脉病变远端扩张处直径 1.0cm ;②有下腔静脉血栓者 ,选择两组支架 ,一组压血栓 ,一组扩张病变 ;③为避免肝静脉开口受压 ,可选择改良血管内支架。结果　收治的 186例患者中 ,149例行PTA ,48例行PTSA(包括 11例PTA后复发者 ) ,11例患者有不同类型并发症 ,余患者随访 1～ 10年疗效良好。结论　依据BCS病变类型准确选择不同内支架疗效良好 Objective To investigate the relationship between the type of inferior vena cava lesions and the choice of stent in Budd-Chiari syndrome. Methods PTA and PTSA treatment of 186 cases of BCS, preoperative color Doppler routine examination. Select the stent within the following requirements: ① stent diameter should be greater than the diameter of the distal dilatation of inferior vena cava 1.0cm in diameter; ② Inferior vena cava thrombosis, choose two sets of stents, a group of thrombosis, a group of dilated lesions; ③ To avoid the opening of the hepatic vein compression, can choose to improve the stent. Results Among the 186 patients treated, PTA was performed in 149 patients and PTSA was performed in 48 patients (including 11 post-PTA recurrences). Eleven patients had different types of complications and the remaining patients were followed up for 1 to 10 years. Conclusion According to the types of BCS, different stents were selected accurately
