    Abstract:
    OBJECTIVE: Subclavian artery aneurysms (SAAs) are uncommon but life-threatening, and a standard treatment approach has yet to be established. The current study aimed to assess the safety and efficacy of endovascular treatment for SAAs. METHODS: The clinical data of 18 SAA patients who underwent endovascular repair at 3 hospitals from January 2009 to December 2019 were retrospectively collected and analyzed. RESULTS: Eighteen patients (12 men and 6 women) with a mean age of 61 years were included. Six patients (33.3%) had a history of hypertension, and 5 (27.8%) had a history of chest trauma. Five patients (27.8%) were asymptomatic. Thirteen (72.2%) SAAs were true aneurysms, and the others (27.8%) were posttraumatic false aneurysms. Endovascular stent graft repair was performed in all patients without conversion to open surgery. The immediate technique success rate was 94.4%, with no postoperative death and only one case (5.6%) of endoleak that was observed on intraoperative angiography and later resolved spontaneously. All patients survived over a median follow-up time of 57 months. Follow-up imaging showed that all stent grafts remained patent, with no endoleak. CONCLUSIONS: Endovascular stent graft repair is feasible, safe, and effective for true and posttraumatic false SAAs and represents a promising treatment option for these SAAs.
