Introduction: To evaluate the feasibility and safety of the Mynx vascular closure device (VCD) for arteriotomy closure after stent placement near the common femoral artery (CFA) access site. Methods: A total of 88 patients (73 men; mean age, 72 ± 9.2 years; 136 procedures) who underwent closure of CFA arteriotomy using the Mynx VCD after stent placement in proximal superficial femoral artery (SFA) with antegrade approach, or in common or external iliac artery with retrograde approach were retrospectively studied. Technical success and access site complication were evaluated. Body mass index (BMI), platelet count, international normalized ratio, prior history of ipsilateral CFA access, access direction, degree of CFA calcification, stent location and diameter, total procedure time, and sheath size were analyzed to evaluate their relationship with technical failure and development of bleeding complications. Results: Technical success was achieved in 94.9% (129/136) patients. The mean time to hemostasis was 0.7 ± 1.8 min. Technical failure was significantly associated with low BMI ( p = 0.001). Other variables presented no significant relationship with technical failure and development of complications. Ultrasonography on the day after the procedure revealed that 8 (5.9%) patients had hematoma. Conclusions: Mynx VCD for arteriotomy closure is feasible and provides hemostatic safety after stent placement near antegrade or retrograde CFA access. However, Mynx VCD may have a poor technical success rate among patients with low BMI.
