Safety and feasibility of a novel vascular closure device in neurointerventional procedures.
This retrospective study evaluated the safety and feasibility of a new arterial femoral access closure device in neurointerventional procedures. The study includes all consecutive adult patients who underwent femoral arteriotomy closure with the MynxGrip™ closure device after Neurointerventional procedures performed between June and December 2012. All patients had a follow-up color Doppler ultrasound (US) within 48 hours after the procedure, which was independently interpreted by two experienced radiologists to evaluate for access site complications. Device success/failure, sheath size, ambulation time, and periprocedural complications were recorded. Fifty-five closure devices were deployed in 53 patients. There were 23 (43%) males and 30 (57%) females; age ranged from 22 to 84 years (mean: 52.1 years). Thirty of the 55 procedures (55%) were therapeutic and 25 were diagnostic interventions (45%). Sheath sizes used were 5F in 35 procedures (64 %) and 6F in 20 procedures (36%). The right femoral artery was accessed in 51 procedures (93 %) and the left in four procedures (7%). There was only one (1.8 %) minor periprocedural complication (small hematoma). Hemostasis was successful in 51 of the 55 procedures (93 %) with subsequent early ambulation. No device-induced complications associated with serious clinical sequelae were reported. In our small series, the MynxGrip™ femoral access closure device provided a safe and feasible way of closing the femoral artery puncture site after neurointerventional procedures with low minor complication rates and no major complications. Further large prospective randomized trials are necessary to evaluate the efficacy of the device.
