The COVID-19 pandemic forced neurosurgery residency application processes to adopt a virtual interview model. This study analyzes the trends in program and applicant residency match behavior due to virtual interviews. ⋯ Despite no change in the overall number of applications submitted per applicant, Black applicants submitted more applications virtually, suggesting potential benefits of virtual format for Black applicants. Interview format was strongly correlated to the use of perceived fitness by applicants in rank decision making. Virtual interviews provide major financial advantages to candidates and could help improve Black representation in neurosurgery. However, they impose limitations on ability access fitness.

Complex middle cerebral artery (MCA) aneurysms incorporating parent or branching vessels are often not amenable to standard microsurgical clipping or endovascular embolization treatments. We aim to discuss the treatment of such aneurysms via a combination of surgical revascularization and aneurysm exclusion based on our institutional experience. ⋯ Cerebral revascularization by bypass followed by aneurysm or parent artery occlusion is an effective treatment option for complex MCA aneurysms that cannot be safely treated by standard microsurgical or endovascular techniques. Double-barrel bypass consisting of 2 STA branches to 2 MCA branches yields adequate flow replacement in most cases.

This study explored the safety and feasibility of surgical treatment of spastic paralysis of the central upper extremity by contralateral cervical 7 nerve transfer via the posterior epidural pathway of the cervical spine. ⋯ Cross-transfer surgery of the contralateral cervical 7 nerve via the posterior epidural pathway of the cervical spine can effectively avoid the risk of nerve and blood vessel damage in anterior cervical nerve 7 transfer surgery; the nerve transfer distance is short, and nerve transplantation is not required. This approach may become a safe and effective procedure for the treatment of central upper limb spastic paralysis.

Temporal changes in the volume of chronic subdural hematoma (CSDH) following middle meningeal artery (MMA) embolization vary. We aimed to determine whether CSDH density on computed tomography is related to hematoma resolution following particle MMA embolization. ⋯ Rapid resolution of CSDH following MMA embolization was associated with low hematoma density at 1-week postembolization. Based on hematoma density on computed tomography at 1-week postembolization, a 1-month follow-up would be sufficient in cases of low density, but a 3-month follow-up would be required in cases of high-density hematoma. Larger studies and clinical trials are needed to confirm our findings.

Clip reconstruction of fusiform A1 segment aneurysm using lateral supraorbital approach.
Fusiform aneurysms of the anterior cerebral artery are a surgical rarity encountered only occasionally by a neurosurgeon.1,2 Seen most commonly in the vertebrobasilar territory, these aneurysms differ in pathophysiology and clinical presentation from their saccular counterparts. Arterial dissections and atherosclerosis are the leading causes of these aneurysms in young and elderly patients, respectively.3 Patients can present with symptoms related to mass effect/compression of adjacent structures or with ischemic symptoms apart from aneurysm rupture. Management of these aneurysms remains challenging owing to the lack of a distinct neck. ⋯ In Video 1, we present a case of fusiform A1 segment aneurysm in a 34-year-old gentleman and demonstrate how the aneurysm was clipped using a lateral supraorbital approach. He made an uneventful recovery with subtle right lower limb weakness. This video shows the technique and utility of a minimally invasive skull base approach for dealing with a fusiform anterior circulation aneurysm.
