Intraoperative magnetic resonance imaging (iMRI) has been recognized as a useful adjunct for brain tumor surgery in pediatric patients. There is minimal data on the use of an offsite intraoperative magnetic resonance imaging operating theater (iMRI OT), whereby vehicle transfer of patients is involved. The primary aim of this study is to validate the feasibility of perioperative patient transfer to use an offsite iMRI OT for patients with pediatric brain tumor. Secondary objectives include the assessment of tumor resection efficacy and perioperative outcomes in our patient cohort. ⋯ In our local context, the use of interhospital transfers for access to iMRI OT is a safe and feasible option in ensuring good patient outcomes for a select group of patients with pediatric brain tumors.

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.

We have reported the surgical outcomes of an anterior column support procedure, the intravertebral cage augmentation technique for the osteoporotic spine. ⋯ The introduced technique is a valuable surgical option for obtaining anterior column support in osteoporotic patients with severely collapsed Kummel disease who require decompression and stabilization procedures using only a posterior approach.

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.

Dual versus single Antiplatelet Therapy in Carotid Artery Endarterectomy: Direct Comparison of Complications Related to Antiplatelet Therapy.
Dual and single antiplatelet therapies are routinely used in carotid artery endarterectomy (CEA). However, the efficacy and safety of these therapies are controversial. The present study aimed to comprehensively compare the clinical outcomes between dual and single antiplatelet therapies in CEA. ⋯ Based on current evidence, using single antiplatelet therapy in CEA may reduce operation time and the incidences of 30-day death, neck hematoma, major bleeding, and myocardial infarction without increasing the risks of transient ischemic attack, stroke, or a longer operation time.
