Safety of percutaneous axillary artery access with a suture-mediated closing device for parallel endograft aortic procedures - a retrospective pilot study.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate the technical success of percutaneous ultrasound-guided access to the infraclavicular axillary artery with a suture-mediated closing device for patients requiring large-sized upper extremity access. PATIENTS AND METHODS: In 18 consecutive patients (17 male, one female, mean age 73.5 ± 9.6 years, range 52-88 years), artery accesses with the preclosing modification for chimney endografts was gained with 20 ultrasound-guided infraclavicular axillary. Retrospectively, the following endpoints were analysed technical success of percutaneous ultrasound-guided puncture of the infraclavicular axillary artery as well as introduction and deployment, primary successful haemostasis by preclosing, bailout procedures, overall complication rate including local vascular, cerebrovascular, and peripheral neurological complications. RESULTS: Ultrasound-guided puncture and preclosing procedure was successful in all patients. Mean sheath size was 9.4 ± 1.6 French. Ultrasound-guided puncture as well as introduction and deployment were successful in all patients (100 %). Primary successful haemostasis by preclosing was 70 % (14/20). Postclosing with one or two devices enabled successful haemostasis in another 15 %. Bailout stent graft implantation was necessary in three accesses (15 %), either by transfemoral (n = 2) or transbrachial (n = 1) route. Overall complication rate was 16.5 %, all of them were minor haematomas. CONCLUSIONS: Percutaneous ultrasound-guided infraclavicular axillary artery access with preclosing modification seems feasible and safe. The access related complication rate is low and complications can potentially be managed by endovascular means.
