Abstract
OBJECTIVE: This paper retrospectively reviews our experience with endovascular and hybrid treatments for subclavian artery aneurysms (SAA). METHODS: Seventeen patients with SAAs were treated at our center between July 2011 and October 2018. Clinical and follow-up data were extracted from the hospital records and retrospectively reviewed. We routinely use endovascular treatments and stenting or axillary-axillary bypass to treat SAA if vertebral artery blood flow requires restoration. Patients were followed up at 3, 6, and 12 months after their operations and yearly thereafter. RESULTS: Median follow-up was 30.5 months. In 6 patients, the SAAs involved the ipsilateral vertebral artery. Simple coil embolization was performed for 1 patient; endovascular covered stenting and coil embolization for 4 patients; and hybrid treatment for 1 patient. In 11 patients, the SAAs did not involve the ipsilateral vertebral artery. Hybrid treatment was performed for 1 patient; thoracic aortic stent implantation with coil embolization for 1 patient; and covered stent placement in the subclavian artery for 9 patients. Among the 9 patients who were symptomatic at presentation, 8 had relief of symptoms. Leakage was observed in 1 patient, but it stopped spontaneously. Stent occlusion occurred in 33% (3/9), but all were asymptomatic, and no interventions were necessary. CONCLUSION: Endovascular and hybrid treatments appear to be effective for SAAs with few complications and good clinical outcomes.
