Dislodgement of coils during endovascular embolization of brain aneurysms is a potentially hazardous complication due to high risk for cerebral infarct and subsequent neurologic deficits or death. We describe a case of whole coil mesh dislodgement due to interaction between the coil loops and a temporary neck-bridging device struts and subsequent successful retrieval of a distally migrated coil into the left middle cerebral artery branch with direct aspiration technique. ⋯ Our case indicates that first-line direct aspiration technique is an atraumatic and effective procedure for coil retrieval when dislodged even in distal cerebral vessels, minimizing the chance for additional retrieval technique-related risks. Interventionists should be aware of coil dislodgment as a potential temporary bridging-neck device related complication.

Spinal surgery is taught and practiced within 2 different surgical disciplines: neurological surgery and orthopedic surgery. We have provided a unified analysis of spine-focused faculty at U.S. residency programs. ⋯ Neurological and orthopedic spine surgery showed similar patterns for the spread of faculty across academic ranks and trends in academic productivity. Marked gender disparity was seen in both neurosurgical and orthopedic surgery, with fewer female spine surgeons seen at every academic rank. Orthopedic spine surgeons had a greater mean fellowship number than did their neurosurgical counterparts, and a lack of fellowship correlated with lower academic productivity in orthopedic, but not neurological, spine surgery.

Use of a contralateral sublaminar endoscopic approach may minimize facet violation and better visualize the dura and cystic lesions during operation. The aim of this study was to introduce a surgical technique for contralateral sublaminar endoscopic removal of lumbar juxtafacet cysts using a percutaneous biportal endoscopic approach. ⋯ A contralateral sublaminar approach using percutaneous biportal endoscopy may be an alternative treatment for symptomatic lumbar juxtafacet cysts. This approach may minimize iatrogenic facet violation and traumatization of posterior musculoligamentous structures.

Surgical Outcomes and Comorbidities in Cushing Disease: 30 Years of Experience in a Referral Center.
Cushing disease (CD) is a rare, poorly understood entity. Our aim was to add our clinical experience of >30 years in a multidisciplinary specialized unit to the global knowledge of CD. ⋯ We observed slightly inferior cure rate after first surgery compared with moderately better relapse rates and time to relapse. Radiotherapy after surgery failure seemed to be more effective than CTSS; however, EETSS may be a valid alternative. Postoperative panhypopituitarism rate after first surgery was lower than expected; after radiotherapy, our results were comparable to other series.

Minimally invasive surgery of small skull base meningiomas is technically challenging. We report the role of endoscopic 5-aminolevulinic acid fluorescence guidance (e-5-ALA-FGS) for small and deep-seated anterior skull base meningiomas. ⋯ Endoscopic 5-ALA fluorescence guidance was shown to be feasible when resecting small and deep-seated skull base meningiomas via minimally invasive approaches. Based on this proof of principle, we encourage its evaluation for the middle or posterior fossa (e.g., internal auditory canal) and other difficult areas (e.g., behind neurovascular structures or the brainstem). The sensitivity and specificity of this method should be prospectively and systematically investigated.
