Idiopathic intracranial hypertension (IIH) is characterized by headache, papilledema, visual field changes and tinnitus with elevated cerebral spinal fluid opening pressures on lumbar puncture. Left untreated, this condition can lead to permanent visual loss. Previous treatment modalities include medical management, therapeutic lumbar puncture and optic nerve sheath fenestration. ⋯ There was a technical success rate of 99% for the stent placement procedure with a total of nine complications (6%). At follow-up (mean 22.3 months), 88% of patients experienced improvement in headache, 97% demonstrated improvement or resolution of papilledema, 87% experienced improvement or resolution of visual symptoms and 93% had resolution of pulsatile tinnitus. In patients with IIH with focal venous sinus stenosis, endovascular stent placement across the stenotic sinus region represents an effective treatment strategy with a high technical success rate and decreased rate of complications compared with treatment modalities currently used.

Although most neurovascular diseases can be treated either by microsurgical or endovascular means, a subset of patients may require a combined approach. Patient transfer from the operating room (OR) to the angiosuite has been a fundamental drawback of this type of approach. ⋯ A combined endovascular and surgical approach conducted in a hybrid OR provides a new strategy for the treatment of complex neurovascular diseases.

Over the past several decades, checklists have emerged in a variety of different patient care settings to help reduce medical errors and ensure patient safety. To date, there have been no published accounts demonstrating the effectiveness of checklists designed specifically for the unique demands of neurointerventional procedures. ⋯ Use of a neurointerventional procedural checklist resulted in statistically significant improvements in team communication and a significant reduction in total adverse events, with uniformly positive staff feedback.

To report two cases of a rare cause of subarachnoid hemorrhage (SAH), including unusual presentation and an emerging and effective treatment option. ⋯ Rupture of aneurysms arising from basilar artery perforators is a rare cause of SAH and attention to this area should be part of an interventionist's search pattern. Aneurysms in this area may not be apparent in the immediate post rupture setting and delayed post hemorrhage angiography has a role in detecting this entity. Stent monotherapy may be effective in treating these lesions.
