title: [Staged bilateral VA embolization for SAH due to bilateral VA dissection: case report].
abstract: Vertebral artery (VA) dissections are uncommon, but are increasingly recognized as a cause of posterior circulation stroke in young adults. We describe a patient with bilateral VA dissection who presented SAH. The patient was successfully treated by proximal coil occlusion of the bilateral vertebral arteries in two stages. In the treatment of SAH due to bilateral VA dissection, it is important to estimate the status of the treated vessels or contralateral vessels by follow-up angiography. Staged bilateral proximal VA occlusions should be considered in the case of recurrent VA dissection or progressive aneurysm enlargement.
