Review Meta Analysis
Neurological complications after left subclavian artery coverage during thoracic endovascular aortic repair: a systematic review and meta-analysis.
Recent studies suggest an increased risk of neurologic complications after coverage of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR). The preventative role of preoperative revascularization of the LSA using carotid-subclavian bypass or transposition remains controversial. We assessed this increased risk and the role of revascularization by undertaking a systematic review and meta-analysis of the literature. ⋯ The risk of neurologic complications is increased after coverage of the LSA during TEVAR. Preemptive revascularization offers no protection against CVA, perhaps indicating a heterogeneous etiology. Revascularization may reduce the risk of SCI, although limited data tempers this conclusion. Improved or perhaps compulsory reporting to registries of a minimum data set may help further assess the exact etiology of these complications and identify a higher-risk subset of patients in whom revascularization might prove protective.

Review Case Reports
Vertebral artery stent graft for a chronic symptomatic vertebrojugular arteriovenous fistula.
A patient with a chronic, symptomatic V2 segment vertebrojugular fistula was successfully treated with a vertebral artery stent graft, with immediate tinnitus resolution. No early or late complications were observed, and at 45 months of follow-up, the patient remains asymptomatic with a patent stent graft. The existing literature on stent graft treatment of vertebrojugular fistula is reviewed.
