Aneurysmal subarachnoid hemorrhage (aSAH) has a high complications burden, with in-hospital mortality as the most devastating outcome. We aimed to develop and validate a risk score for early prediction of in-hospital mortality after aSAH. ⋯ Risk of in-hospital mortality after aSAH can be predicted with high accuracy using baseline characteristics. The novel risk score showed best diagnostic performance in the construction and validation cohorts and can aid in early prognostication and treatment decisions.

Ventriculoperitoneal (VP) shunt surgery is the primary treatment for patients with idiopathic normal pressure hydrocephalus (iNPH). This study compared the outcomes of VP shunt placement using electromagnetic (EM) navigation versus standard methods in patients with iNPH, focusing on catheter accuracy and postoperative complication rates. ⋯ The use of EM navigation in VP shunt placement for patients with iNPH improves catheter placement accuracy, reduces postoperative complications and shunt malfunction rates, and provides precise and individualized surgical treatment.

Revision surgery of microvascular decompression for hemifacial spasm: 2-Dimensional operative video.
Although microvascular decompression is highly effective for treating hemifacial spasm, cases of ineffectiveness and recurrence can still occur. Ineffectiveness is primarily due to missed neurovascular compression (NVC), whereas recurrence is most often caused by adhesion of Teflon pledgets (Chestmedical Co., Ltd., Shanghai, China), both of which may necessitate revision surgery.1,2 However, adhesions in the surgical area make revision surgeries more difficult. This video presentation includes 2 cases of revision surgery for hemifacial spasm (Video 1). ⋯ The second case involved a missed NVC, where the pledget was improperly placed between the artery and the cisternal portion of the facial nerve during the initial surgery, overlooking compression at the REZ, an error more common in less experienced centers. Subsequent decompression of the REZ resulted in full symptom relief. Our experience highlights the importance of thorough decompression of the REZ while ensuring the pledget does not come into direct contact with the REZ to prevent long-term adhesions and recurrent hemifacial spasm.
