Periprocedural intracranial hemorrhage during Wingspan stent deployment. A, One patient’s blood pressure suddenly increased to more than 200 mm Hg after the microwire passed through the stenosis; cone beam CT showed SAH in the right sylvian fissure, and the procedure was terminated without stenting. B, One patient who underwent PTAS with a Wingspan stent achieved <30% residual stenosis. A routine postprocedural cone beam CT scan revealed SAH in the left sylvian fissure. CT = computed tomography; PTAS = percutaneous angioplasty and stenting; SAH = subarachnoid hemorrhage.
