Long-term durability and recurrence patterns after endovascular treatment for basilar tip aneurysms.
Treating recurrence after coil embolization of basilar tip aneurysm remains challenging even with the development of endovascular procedures. The present study evaluated long-term durability and recurrence patterns after endovascular treatment of basilar tip aneurysms. ⋯ Recurrence after coil embolization for basilar tip aneurysms is associated with large aneurysms and incomplete occlusion at initial embolization. Understanding the patterns of recurrence is useful for predicting recurrence and selecting treatment strategies.

The role of chemotherapy (CT) in the treatment of adult patients with medulloblastoma (MB) is unclear. The aim of this study is to compare the survival difference between adult patients with MB treated with and without chemotherapy. ⋯ CT improved CSS for adult patients with MB. With therapeutic advances, adult patients with MB might benefit from the use of CT.

The O-arm as an additional tool to confirm optimal ventricular tip position - a technical note.
Ventricular catheter placement can be a challenging procedure when treating patients with slit ventricles, despite the use of a neuronavigation system. ⋯ This short technical note describes an easy technique for using the O-arm to confirm the optimal ventricular drain position.

Although rare, intramedullary spinal cavernous malformations have a 1.4%-6.8% annual hemorrhage risk and can cause significant morbidity.1 Prior hemorrhage and size >1 cm are risk factors for future hemorrhage that, in addition to notable or progressive symptoms, may justify early surgical intervention.1,2 In this video, we present key steps in surgical management of a large, symptomatic thoracic cavernous malformation. A 56-year-old woman presented with worsening lower extremity weakness, imbalance, and difficulty ambulating. Strength was 3/5 in her right lower extremity and 4/5 in her left lower extremity. ⋯ Postoperatively, the patient had improved left lower extremity strength and stable right lower extremity strength but worsened dorsiflexion (1/5), which improved with rehabilitation. At 1-year follow-up, she had full strength in her left lower extremity and 4/5 in her right lower extremity, with mild paresthesias below T10. Consistent with prior series demonstrating low complication rates and good long-term neurological outcomes,2 microsurgical resection of selected symptomatic intramedullary spinal cavernous malformations can halt neurological decline and potentially improve neurological function.

Virtual learning has made neurosurgery education more available to medical students (MSs) of all stages than ever before. We aimed to evaluate the impact of on-site learning in order to assess whether a return to this method of teaching, when safe, is warranted for MSs of all years. ⋯ Neurosurgical education initiatives for MSs should continue to be developed. Hands-on neurosurgical training experiences for MSs serve as a valuable educational experience. Improvement in training models will lead to capitalizing on MS education to better improve readiness for neurosurgical residency without concern for patient safety.
