    Abstract:
    OBJECTIVE: The aim of this study was to assess the safety and effectiveness of upper extremity access (UEA) with percutaneous closure of the axillary artery (AxA) during endovascular treatment of thoracoabdominal aortic aneurysms with fenestrated and branched endografts. METHODS: Between January 2014 and 2017, 34 out of 37 patients (92%) required UEA during a staged branched and fenestrated endovascular approach. A percutaneous AxA (pAxA) approach was used in 14 consecutive patients (41%) with the off-label use of two Perclose ProGlide (Abbott Vascular, Santa Clara, Calif) devices. The results of patients who had received a pAxA access were analyzed; technical success was defined as successful arterial closure with no evidence of persistent bleeding or arterial occlusion requiring secondary interventions. Early (30 days) and short-term (6 months) success rates were recorded. The anatomic characteristics of the AxA of the entire cohort (34 cases) were studied. RESULTS: Primary technical success of pAxA was 100%; in one case, an adjunctive Perclose ProGlide device was used to achieve complete closure. No secondary open or endovascular procedures were required. At predischarge computed tomography, no intimal defects, pseudoaneurysms, or signs of bleeding were observed, and all patients were discharged without neurologic deficits related to the AxA puncture site. All 14 patients are alive at follow-up, and 9 of 14 patients completed a 6-month clinical follow-up with computed tomography examination; no late complications were observed at the site of UEA percutaneous repair. With regard to the anatomic characteristics of the AxA, the vessel diameters in the first and third segments were statistically different (P < .001) with a median difference of 1.5 mm (1.0-2.0 mm), with no differences between the right and left sides. The distance between the end of the first segment of the AxA and the origin from the aortic arch was statistically different between the right and left sides, with a median difference of 36 mm (17-50 mm). A positive linear correlation was found between the diameter of the AxA and the height of the patients. CONCLUSIONS: AxA is adequate in terms of both caliber and lack of calcifications as an access vessel for large-sheath catheterizations, and it might be considered an alternative UEA for complex aortic endovascular procedures thanks to its proximity to visceral target vessels. In this preliminary experience, percutaneous closure of AxA access with the Perclose ProGlide device is clinically safe and technically feasible with high rates of success.
