Objective: To present our experience of the endovascular treatment of subclavian artery aneurysms (SAAs) and analyze the clinical manifestations, imaging findings and treatment outcomes.
Methods: In this retrospective study, nine patients with SAAs underwent endovascular stent placement in our center between July 2011 and June 2016. Clinical features, imaging findings, treatment outcomes and follow-up results of these SAA patients were retrospectively analyzed.
Results: Nine patients were diagnosed with SAAs by computer tomography angiography (CTA). Five patients underwent percutaneous endovascular stent placement in the subclavian artery. Three patients underwent endovascular repair of the SAAs with coil embolization and stent graft. One patient underwent stent graft implantation by the simultaneous kissing stent technique. Five patients had their symptoms relieved and thrombosis occurred in one case. The mean follow-up period was 17 months, ranging from 8 to 40 months.
Conclusion: For patients with SAAs, endovascular treatment is a feasible choice, with a high success rate, few complications and good clinical outcomes.
