Introduction:
Pseudoaneurysms of the subclavian artery are a rare complication. Surgical treatment is necessary to prevent potentially lethal complications. This needs adequate planning in cases that require vertebral artery revascularisation.
Report:
A 56 year old man with multiple systemic comorbidities underwent endovascular treatment using a balloon expandable bare metal stent for symptomatic subclavian Steal syndrome. During follow up, computed tomography angiography (CTA) revealed a pseudoaneurysm in the proximal segment of the left subclavian artery. The patient had criteria warranting left vertebral artery revascularisation. The patient underwent scheduled hybrid surgical treatment involving transposition of the vertebral artery to the common carotid artery, endarterectomy of the internal carotid artery, and endovascular therapy for pseudoaneurysm exclusion; all were performed on the left side. The post-operative period was without incident. After 12 months the patient remains asymptomatic, with adequate exclusion of the pseudoaneurysm, and patency of the procedures.
Discussion:
Hybrid surgery could offer a secure, feasible, and less invasive option for treating subclavian artery pseudoaneurysms that require vertebral artery revascularisation.
