Abstract
Background: Vascular access site complications (VASCs) after endovascular interventions requiring a large-bore access are frequent and known to be associated with increased morbidity and mortality. Although balloon-expandable covered stents (BECSs) are increasingly used in such indications, their performance in this rather hostile territory is currently unknown. We aimed to evaluate the safety and efficacy of BECSs in common femoral artery (CFA) VASCs management. Methods: This is a national multicenter retrospective study of all patients who underwent BECS implantation of the CFA due to a VASCs after an endovascular procedure between January 2020 and May 2023 in major tertiary referral centers in Hungary. Operative data were collected and follow-up ultrasound examinations were performed. Our study is registered on ClinicalTrials.gov (NCT05220540) and followed the STROBE guidelines. Results: Of the 23 patients enrolled (13 females, mean age: 74.2 ± 8.6), technical success was achieved in 21 (91.3%) cases, with one perioperative death. After an average follow-up of 18.0 ± 11.4 months, another nine (39.1%) deaths occurred, and one was VASCs-associated. BECS occlusion was detected in one (4.3%) patient, being the only reintervention (4.3%) where revascularization was also achieved. Conclusions: Although BECS implantation for CFA VASCs is feasible with a relatively high technical success rate, the mortality rate is non-negligible. Until adequately evaluated, BECS implantation in such indications is to be used with caution, ideally only within the framework of a trial.
