Case Reports
OLIF combined with anterior fixation for lumbar synovial cysts with instability: a case report.
The optimal management of lumbar synovial cysts (LSCs) has always been controversial. Open or minimally invasive partial hemilaminotomy as a direct decompression approach has been widely studied, whereas to our knowledge, there has been no report of an indirect decompression method for LSC. ⋯ Indirect decompression surgery may be a new option for the management of LSC, especially in those with lumbar instability and that communicate with the facet joint. Further research with a larger and more comprehensive sample population is required.

Comparative Study
Post-embolization change in MRI contrast enhancement of meningiomas is a better predictor of intraoperative blood loss than angiography.
Preoperative embolization of meningiomas to reduce tumor vascularity and intraoperative blood loss remains controversial. Incomplete devascularization on angiography is not significantly correlated with intraoperative estimated blood loss (EBL). Magnetic resonance imaging (MRI) may provide a better assessment of devascularization and prediction of EBL. ⋯ Postembolization contrast-enhanced MRI is a better predictor of intraoperative blood loss during meningioma resection than postembolization angiography, which overestimates the degree of embolic devascularization. Postembolization preoperative MRI is warranted for optimal patient management.

Chronic subdural hematoma (cSDH) is an increasingly common condition due to the growing use of anticoagulation. Currently, there remains a lack of evidence to guide the optimal timing of anticoagulant reinitiation for stroke prevention in atrial fibrillation after cSDH evacuation. We aimed to better understand the perceived risks of hemorrhagic and embolic complications along with current practice patterns on restarting anticoagulation after surgical evacuation of cSDH. ⋯ There is considerable variation in current practice patterns and perceived risks of embolic and hemorrhagic complications with anticoagulation reinitiation after cSDH evacuation. These results demonstrate clinical equipoise that warrant further targeted investigation in large-scale randomized controlled trials.

Spinal hematomas are rarely associated with dengue syndrome and usually occur at the time of active dengue fever. Late presentation after recovery from dengue fever, intradural hematoma, presentation as a multiloculated cystic lesion with longitudinal extensive myelitis, and recurrence after surgery are rarely or not described. Due to the peculiar association of all these findings, we report this case to provide insight into the existence of such a rare presentation. ⋯ Spinal hematoma should be kept in mind in patients who present with neurologic complications after dengue fever. It can have an atypical radiologic presentation and may present with recurrent hemorrhage after surgery. Attention should also be given to delayed presentation of neurologic complications, which may develop even after weeks of recovery from dengue fever.

Cerebral edema is a major cause of morbidity in patients with severe traumatic brain injury (TBI). Intraparenchymal thermal conductivity-based probes that measure local cerebral blood flow can measure percent brain tissue water (%BTW) content, but such measures have been insufficiently characterized in patients with TBI. ⋯ %BTW may be a clinically useful, real-time measurement of cerebral edema in patients with TBI. It is closely associated with the serum sodium concentration and follows a characteristic temporal course with characteristic trajectory and stability over time.
