Ultrasound-Guided Deployment of a Plug-Based Vascular Closure Device in Femoral Arteries with Calcified Plaque or Stenosis

Abstract

From January 2019 to January 2020, 106 patients (age, 64.8 +/- 14.1 years; male, 63.2%) were included to retrospectively investigate the feasibility and safety of ultrasound-guided deployment of ExoSeal after femoral artery access. Baseline characteristics were not different except for age (P =.022), body mass index (P =.009), and diameter (P <.001) between the calcified plaque or stenosis (CS) group (n = 49) and non-CS group (n = 57). The overall technical and clinical success rates were 96.2% and 100%, respectively. The technical (CS group, 48/49; non-CS group, 54/57) and clinical success rates (100%), time to hemostasis (CS group, 3.21 +/- 0.54 min; non-CS group, 3.39 +/- 0.71 min), and complication rates (CS group, 1/49; non-CS group, 0/57) were not different between the 2 groups. ExoSeal seems to be safe to use under ultrasound guidance in the femoral arteries with CS.
