METHODS A scoping review following the PRISMA Protocols Extension for Scoping Reviews was performed. Available full-text studies published in English (PubMed, Cochrane and EMBASE databases; last queried, 31 June 2022) were systematically reviewed and analysed. Data were reported as descriptive narrative or tables, without any statistical analysis nor quality assessment. RESULTS Fourteen retrospective articles were included. Seven articles studied the use of upper extremity access (UEA) during branched-fenestrated endovascular aortic repair, 3 studied the use of steerable sheaths and 4 included both approaches. A left UEA was used in 757 patients (technical success: 99%, stroke rate: 1–3%) and a right UEA in 215 patients (technical success: 92–98%, stroke rate: 0–13%). Seven studies (1066 patients) described a surgical access only (technical success: 80–99%, stroke rate: 0–13%), while 3 studies (146 patients) described a percutaneous access only (technical success: 83–90%, stroke rate: 3%) and lastly 4 studies compared UEA versus use of steerable sheaths from the transfemoral approach (TFA) (UEA: 563 patients, technical success: 95–98%, stroke rate: 1–8%; TFA: 209 patients, technical success: 98–100%, stroke rate: 0–1%). CONCLUSIONS Both UEA and TFA as cannulation approaches were associated with high technical success and low perioperative complications. Currently, there is a paucity of high-quality data to provide definitive indication. Optimal UEA in terms of side (left versus right) and approach (surgical versus percutaneous) needs further study.
