Distal outflow occlusion and extracranial-intracranial bypass represent a possible option for the surgical management of complex middle cerebral artery (MCA) aneurysm. A limitation of the distal clipping strategy combined to bypass is related to the difficulties in predicting intraoperatively the good blood flow supply to the brain territory distal to the aneurysm and the extent and speed of aneurysmal thrombosis. ⋯ We present the first report of a synergistic intraoperative utilization of ICG-VA and CEUS in studying parenchymal perfusion and aneurysm flow in complex neurovascular procedures.

Intracranial vascular infections of fungal etiology are extremely rare. Most cases occur in immunocompromised patients with invasive fungal disease, most commonly originating in the paranasal sinuses or the lungs. Granulomatous invasive rhinosinusitis, which is extremely rare in North America, has been reported to affect immunocompetent patients in most cases, and its causative strain has potential to invade the intracranial arteries. We present a rare case of basilar artery rupture and infarction secondary to granulomatous invasive rhinosinusitis. ⋯ Invasive fungal rhinosinusitis is more frequent nowadays owing to increased use of immunosuppressive therapies. However, it is still a disease that mostly affects immunocompromised patients. The development of new microbiologic investigation techniques has enabled the discovery of fungal diseases that can also affect immunocompetent hosts, such as granulomatous invasive rhinosinusitis. This is an extremely rare condition in North America, with very few cases documented in the last few decades.

Dural closure is a routine surgical step in neurosurgery. The benefit of suturing the dura to achieve watertight closure-with or without the use of dural substitutes-has been questioned in supratentorial craniotomy. We performed a retrospective study to examine the possible benefits and harms of suturing the dura compared with no dural closure and the occurrence of postoperative infection, cerebrospinal fluid (CSF) leak, and postcraniotomy headaches. ⋯ We found no difference in the occurrence of CSF leak, infection, or surgical site swelling between the closed and open groups. The incidence of postcraniotomy headaches was greater in the closed group, and the difference was statistically significant.
