Choriocarcinoma coexisting with or after normal pregnancy is extremely rare. To our knowledge, our case report is the first time cerebral mycotic pseudoaneurysms from choriocarcinoma have been proven angiographically. ⋯ Metastatic choriocarcinoma is rarely considered during a viable pregnancy but is almost always fatal if unrecognized. Early recognition enhances the chances of cure with chemotherapy. Arteriovenous malformations are typically considered in young women with intracerebral hemorrhages and have higher risk of rupture in pregnant women, but physicians should also be aware of metastatic choriocarcinoma and the development of mycotic aneurysms in peripartum women with intracerebral hemorrhages.

Recurrent symptoms of sciatica after previous surgical intervention is a relatively common and troublesome clinical problem. Percutaneous endoscopic lumbar decompression has been proved to be an effective method for recurrent lumbar disc herniation. However, the prognostic factors and outcomes of percutaneous endoscopic lumbar reoperation (PELR) for recurrent sciatica symptoms were still unknown. The purpose of this study was to evaluate the outcomes and prognostic factors of patients who underwent PELR for recurrent sciatica symptoms. ⋯ PELR is a safe and effective treatment for recurrent sciatica symptoms regardless of different primary operation type. Obesity, inferior surgeon level, and patient age older than 40 years were associated with a worse prognosis. Obesity was also a strong and independent predictor of re-recurrence sciatica symptoms after percutaneous endoscopic lumbar decompression.

Safe burr hole surgery for chronic subdural hematoma using dabigatran with idarucizumab.
Chronic subdural hematoma (CSDH) is a common intracranial hematoma. The number of patients who undergo anticoagulant therapy including a direct oral anticoagulant (DOAC) is expected to increase. Recently, idarucizumab, the antidote for dabigatran, which is a DOAC, has been developed. We successfully treated CSDH with dabigatran using emergency burr hole surgery and idarucizumab. ⋯ Dabigatran should be used for atrial fibrillation detected after head trauma. Emergency surgery can be safely performed for CSDH with dabigatran using idarucizumab.

Spaceflight and the associated gravitational fluctuations may impact various components of the central nervous system. These include changes in intracranial pressure, the spine, and neurocognitive performance. The implications of altered astronaut performance on critical spaceflight missions are potentially significant. The current body of research on this important topic is extremely limited, and a comprehensive review has not been published. Herein, the authors address this notable gap, as well as the role of the neurosurgeon in optimizing potential diagnostic and therapeutic modalities. ⋯ The microgravity environment encountered during spaceflight impacts intracranial physiology. This includes changes in intracranial pressure, the spinal column, and neurocognitive performance. Herein, we present a systematic review of the published literature on this issue. Neurosurgeons should have a key role in the continued study of this important topic, contributing to both diagnostic and therapeutic understanding.

Posterior-anterior spondylodesis is often used to stabilize the spine in various pathologies. The anterior procedure is often performed via thoracoscopy. It is unclear whether the anterior procedure should be performed immediately after posterior instrumentation or after the patient has convalesced. This retrospective study compared perioperative safety and morbidity in 1-stage versus 2-stage posterior-anterior fusion surgery with a thoracoscopic anterior approach. ⋯ One-stage stabilization was as safe as 2-stage stabilization and associated with shorter hospitalization. Greater pain after the 1-stage procedure, which resolved 30 days after surgery, reflects the fact that 2-stage patients already had pain relief when they underwent thoracoscopy.
