Background: Aneurysms of the subclavian artery are usually the result of trauma, atherosclerosis, or thoracic outlet syndrome. Until the 90s, open surgical repair was considered the only therapeutic choice, exhibiting high complication rates. Since the first report of endovascular repair of subclavian aneurysms in 1991, promising results have been published. The aim of this review was to summarize all available data on subclavian artery (SA) true and false aneurysm stenting to reach conclusions regarding morbidity, mortality, and other procedure-related characteristics. Methods: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines. Eligible studies were sought in the Medline (PubMed), ClinicalTrials.gov, and Cochrane library–Cochrane Central Register of Controlled Trials (CENTRAL) databases through February 2017 using the following MeSH terms: “endovascular”, “hybrid”, “aneurysm”, “pseudo-aneurysm”, “pseudo-aneurysm”, “false aneurysm”, “arterial injury”, “subclavian artery”, “axillo-subclavian,” and “axillosubclavian artery”. The reference lists of eligible articles and pertinent reviews were screened for potential relevant studies. Results: Seventy-three studies encompassing data on 142 patients who underwent endovascular or hybrid SA aneurysm repair were deemed eligible. One hundred forty-seven stents and stent grafts were used. Median age of all patients was 56 years, and males comprised 46% of the study sample. Trauma was the most common mechanism of injury. Pulsatile mass or hematoma was the most frequent presenting sign. Pseudoaneurysms were the most frequent type of aneurysms, followed by true aneurysms. Most authors used self-expanding polytetrafluoroethylene-covered stents. Access was obtained by either brachial, femoral, or both arteries. Through-and-through technique was also used in angulated vessels. All-cause mortality was 10.6%, slightly higher to that already reported in literature and lower to the respective rate of the open repair. Reintervention rate was 8.5% despite the high 15.5% complication rate. Conclusions: Endovascular SA aneurysm repair is a technically feasible technique, useful in both elective and emergency cases. Although preliminary results quote its safety and efficacy, larger cohort studies are warranted to elucidate its benefit in treating SA aneurysms. © 2017 Elsevier Inc.
