Abstract

OBJECTIVE:

Percutaneous access during endovascular aortic repair has been shown to be feasible and safe using a suture-mediated closure device ("Preclose" technique) for closure of up to 24F introducer sheaths. The purpose of this study is to examine the late outcomes of those femoral arteries repaired in this manner.

METHODS:

The Preclose technique has been previously described. Briefly, the technique involves two Perclose Proglide devices deployed in the femoral artery prior to insertion of the large diameter introducer sheath and then closure of the arteriotomy by tying down knots of the Proglide following removal of the sheath. The medical records of all patients who underwent endovascular aortic repairs using the Preclose technique between December 2004 and August 2007 were reviewed. Follow-up protocol consisted of computed tomography (CT) angiograms performed at 1, 6, and 12 months, and annually thereafter. All Preclose patients who had at least a 6-month postoperative scan were included in the study. For each patient, the most recent postoperative scan was compared with the preoperative scan for evidence of any new anatomic abnormalities of the femoral artery such as dissection, stenosis, or pseudoaneurysm. Three-dimensional post processing with multiplanar reconstructions was also performed as necessary to confirm axial scan findings.

RESULTS:

A total of 292 patients underwent percutaneous endovascular aortic repairs (TEVAR-125, EVAR-167). Four hundred thirty-two femoral arteries were closed with 870 devices. Four hundred eighteen vessels were approximated with two devices, while 30 arteries required three devices for hemostasis and an additional four vessels only required a single device. Two hundred seventy-eight (64.3%) vessels were accessed with sheaths 18 to 24F. Four hundred eight femoral arteries (94.4%) were closed successfully with the Preclose technique. There were 100 patients (TEVAR-35, EVAR-65) who had adequate postoperative CT scan at 6-months or later. The mean follow up was 11.6 +/- 5.0 months. Of the 156 femoral arteries in these 100 patients repaired using the Preclose technique, there were 3 late complications in 3 patients, 1 asymptomatic femoral artery dissection, and 2 femoral artery pseudoaneurysms requiring surgical repair, resulting in a late complication rate of 1.92% (3/156).

CONCLUSION:

Percutaneous closure of femoral arteries after large diameter introducer sheaths using the Preclose technique has a low incidence of early and late complications related to the closure site.
