1、髂股静脉病变腔内介入治疗器械优选方案,髂股静脉疾病严重降低患者生活质量,欧美国家多所临床中心已应用腔内介入技术进行治疗,工欲善其事必先利其器,何谓专业的髂股静脉支架,特性,规格,镍钛合金材质 激光雕刻 开环支架,14/16mm 直径 60/100/140mm 长度,We considered lumen diameter as follows: 24-mm IVC16-mm common iliac vein14-mm external iliac vein12-mm common femoral vein.,关于血管解剖直径的推荐,Stents were oversized 2 mm com
2、pared with contralateral healthy venous segment diameter.,良好的柔顺性至关重要,Horizontal direction of left common iliac vein resulting early in-stent thrombosis due to turbulent flow when single oblique stent placed,由于支架植入后的水平方向上髂总静脉血管倾斜，可能导致早期的血栓形成,良好的柔顺性至关重要,长期耐受前方髂动脉的搏动挤压,顺应髂静脉的生理弯曲,跨腹股沟韧带,金属抗疲劳性能,Zilver
3、Flex,支架能够受4亿次的搏动循环，支架上的支柱应无断裂，支架应保持一个完整性连接结果,非重叠支架在可扩张静脉径向负载、轴向负载、弯曲负载和May-Thurner负载条件下的疲劳：疲劳安全系数1.0,Zilver Vena,金属抗疲劳性能,合格,可扩张静脉径向负载：3.9 轴向负载：5.0弯曲负载（胯关节）：2.4 May-Thurner负载：4.2,合格,Zilver Flex,Zilver Vena,20 Patients treated for iliacfemoral venous obstruction between January 2011 and December 2012
4、were retrospectively. Stents extended into IVC in 9 patients and under the inguinal ligament in 13 patients.In comparison to the Wallstent, the Zilver Vena is able to be more accurately positioned, does not foreshorten, and utilizes a smaller sheath.,Iliofemoral venous stenting extending into the fe
5、moral region: clinical experience with the purpose-designed Zilver Vena stentG.J.OSULLIVAN,临床应用相关报道,支架定位不该成为困扰,支架定位不该成为困扰,东直门医院,左髂静脉闭塞病例，术中可见左髂总静脉开口处病变。予以Zilver Vena治疗,径向支持力的优势体现,平台,特性,Zilver 支架设计平台,独特设计使得其径向支持力远远大于同规格动脉支架,径向支持力的优势体现,typical appearance of a post thrombotic vein after axial phlebotom
6、y,the fibrotic scar tissue resulting from a long standing clot is surgically shaved from the vein wall.,径向支持力的优势体现,Occlusive lesions were found in 26 limbs (63%; occlusive/stenotic lesions ratio, 1.7:1). Overall procedure success was 95%. Success was achieved in all stenotic lesions. Two limbs with
7、occlusive lesions were not recanalized after three attempts.,通路系统的重要性,Endovascular treatment of iliofemoral chronic post-thrombotic venous flow obstruction,KCFW-8.0-38-RB,CXI-4.0-35-90-P-NS-0,HPWA-35-180,ATB5-35-80/120-14-4.0/2.0,器械搭配推荐,KCFW-8.0-38-RB,THSF-35-180-AES,ATB5-35-80/120-14-4.0/2.0,ZVT7-35-80-14/16-6.0/10.0/14.0,器械搭配推荐,Celect下腔静脉滤器,更长的回收时间窗更高的回收成功率更从容的溶栓选择,Thank for your attention,
