完全穿刺技术在腹主动脉瘤腔内修复术中的应用

目的 探讨应用Perclose ProGlide缝合器完全穿刺技术行腹主动脉瘤腔内修复术的安全性和有效性.方法 2008年5月至2010年4月,36例腹主动脉瘤患者完全穿刺下行腔内修复术治疗.其中男性30例,女性6例;平均年龄68岁.所应用的支架型血管包括:3例Endurant,13例Talent,20例Zenith.18～24 F的鞘管预置两把ProGlide,14～16 F的鞘管预置单把ProGlide.缝合动脉切口时取出鞘管并将线结下滑收紧.统计技术成功率、相关并发症及手术操作时间.术后3、6、9、12个月及其后每年进行CT血管造影随访.结果 20例局部麻醉,16例全身麻醉.68条股动脉共应用128把ProGlide,其中38条股动脉各应用2把,8条各应用3把,2条各应用4把,20条各应用1把.63条股动脉(63/68,92.6%)技术操作成功,2条中转切开缝合,3条出现血肿,无需手术处理.平均随访时间(12±3)个月.1例于术后3个月出现无症状的动脉夹层.结论 完全穿刺技术在腹主动脉瘤腔内修复术中的应用是安全和有效的.由于可能需要切开缝合,建议在杂交手术室中操作.

Total percutaneous endovascular abdominal aortic aneurysm repair

Objective To determine the safety and efficacy of total percutaneous endovascular abdominal aortic aneurysm repair using the Perclose ProGlide suture-mediated closure system. Methods From May 2008 to April 2010, 36 abdominal aortic aneurysm patients were undergoue total percutaneous endovascular repair. There were 30 male and 6 female patients with a mean age of 68 years. Endografts used included 3 Endurant endogafts, 13 Talent endografts, and 20 Zenith endografts. Prior to insertion of the introducer sheath, two ProGlides were pre-set to 18 to 24 F access sites and one to 14 to 16 F access sites.At last, suture the arteriotomy by tying down knots of the ProGlide following removal of the sheath. Technical success, complications, and procedure and access closure times were evaluated. Follow-up protocol consisted of computed tomography angiograms performed at 3, 6, 9, 12 months, and annually thereafter.Results Twenty patients were operated under local anesthesia and 16 patients under general anesthesia. A total of 68 femoral arteries were closed with 128 devices. Thirty-eight vessels were with 2 devices, while 8 arteries required 3 devices and 2 arteries required 4 devices for hemostasis and an additional 20 vessels only required a single device. Sixty-three (63/68, 92. 6% ) vessels were closed successfully. Two vessels converted to open closure. Three vessels complicated with hematomas without surgical procedure. The mean follow-up was ( 12 ± 3 ) months. There was one asymptomatic femoral artery dissection 3 months after operation. Conclusions Total percutaneous endovascular abdominal aortic aneurysm repair is safe and effective. But it should be performed at hybrid operating room where can convert to open procedure if necessary.
