[Total percutaneous endovascular abdominal aortic aneurysm repair]

To determine the safety and efficacy of total percutaneous endovascular abdominal aortic aneurysm repair using the Perclose ProGlide suture-mediated closure system.

From May 2008 to April 2010, 36 abdominal aortic aneurysm patients were undergone total percutaneous endovascular repair. There were 30 male and 6 female patients with a mean age of 68 years. Endografts used included 3 Endurant endografts, 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.

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.

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.
