Background: The aim was to analyze the anatomic feasibility of the percutaneous axillary access (PAXA) using cadaverous models and then to analyze the complications associated with PAXA during Fenestrated or Branched Endovascular Aneurysm Repair (F/BEVAR) procedures.
Methods: Cadaverous models were used to analyze axillary pedicle after a PAXA on an initial anatomical investigation. A subclavian approach was performed after puncture to assess the injuries caused by the needle. Then, in an observational study, patients who underwent F/BEVAR using a PAXA between July 2019 and July 2021 were included. PAXA-related events and complications were monitored.
Results: Eleven dissections were performed on cadavers. The axillary vein was injured twice (18.2%); the puncture site on the axillary artery was found on the arterial proximal part, behind the clavicle. Fifty-three patients underwent a F/BEVAR using a PAXA. The mean (SD) age of patients was 74.5 (9.7) years. Most indications for endovascular repair were para-renal aneurysms (66%). Two Proglide® closure devices served to close arterial access in all procedures. Adjunct balloon inflation was used in 19 (35.8%) patients. There were 5 (9.4%) PAXA-related events included preoperative blush in 2 (3.8%) patients, axillary artery dissection in 2 (3.8%), and 1 (1.9%) axillary artery stenosis. Five patients (9.4%) had a postoperative axillary hematoma without need for additional surgical procedure. No PAXA-related complication was found after discharge (mean [SD] 11.7 [7.4] months following surgery).
Conclusions: Percutaneous axillary artery access was an efficient upper extremity access and associated with a low rate of PAXA-related events.
