A Retrospective Analysis of Surgical Femoral Artery Closure Techniques: Conventional versus Purse Suture Technique.

Background: Different techniques have been reported for the exploration and repair of femoral artery (FA) in patients who undergo minimally invasive cardiac surgery (MICS) and endovascular aortic surgery. We used a modified approach alternative to the conventional technique (group CT) since May 2013, which specifies a shorter groin incision and diamond-shaped hemostatic purse sutures for arteriotomy closure without the requirement of cross-clamping (group PT [purse suture technique]) and evaluated early outcomes and the complication profiles of the 2 techniques for femoral access.
Methods: In our clinic, between May 2011 and December 2015, 503 FA cannulations were performed on 345 patients who underwent MICS (n = 109, mean age 64.1 ± 17.6 years, female/male ratio 71/38), endovascular abdominal aneurysm repair (n = 158, mean age 71.3 ± 10.2 years, female/male ratio 63/95), thoracal endovascular aneurysm repair (n = 50, mean age 65.0 ± 15.3 years, female/male ratio 15/35), and transaortic valve implantation (n = 28, mean age 80.8 ± 5.9 years, female/male ratio 13/15). A total of 295 FAs were exposed via mini incision and were repaired with the PT. We compared the duration of femoral closure (FC), wound infection, and vascular complications including bleeding hematoma, thromboembolic and ischemic events, pseudoaneurysm, seroma, surgical reintervention rates, delayed hospital stay for groin complications, and existence of postoperative local luminal narrowing (LLN) at the intervention site over 25% for both groups.
Results: FC time (CT 14.9 ± 3.16 min, PT 6.5 ± 1.12 min, P < 0.0001), bleeding hematoma frequency (CT 6.2%, PT 1.7%, P = 0.01), and prolonged hospital stay for groin complications (CT 14.9%, PT 3.4%, P < 0.0001) were significantly lower in the PT group. Rate of technical success (CT 80.3%, PT 87.4%, P = 0.03) and event-free patient (CT 66.1%, PT 77.5%, P = 0.03) were significantly better in the PT group. There were no differences between groups in terms of ischemic events, wound infection rates, development of pseudoaneurysm and seroma, surgical reintervention rates, and LLN of FA over 25% at 6-month duplex evaluation.
Conclusions: The comparison of the 2 approaches revealed the advantages of the PT in terms of bleeding hematoma and shortening in FC time and the length of hospital stay. We suggest performing a smaller skin incision for FA access and utilizing purse sutures, which allows completing the procedure without cross-clamping, thus providing a favorable approach and excellent comfort for the surgeon.
