Vertebrobasilar insufficiency can be refractory to medical therapy. Surgical revascularization may augment posterior circulation perfusion. We present a 39-year-old with recurrent posterior circulation strokes due to bilateral vertebral artery occlusion and compromised collateral circulation. Patient underwent OA-V3 bypass via an extreme lateral infracondylar approach to restore vertebrobasilar perfusion. This skull base approach offers distinct advantages, utilizing a minimally invasive technique through a small retromastoid incision without intradural exposure and or need for an intervening graft.
