To assess the validity of the Caprini risk assessment model (RAM) in risk stratification for deep vein thrombosis (DVT) and to investigate the diagnostic value of Caprini score combined with D-dimer in predicting DVT. ⋯ The Caprini RAM is an effective and reliable DVT risk stratification tool in patients with thoracolumbar fractures caused by high-energy injuries. Caprini score >8 or D-dimer >1.81 mg/L may predict the occurrence of preoperative DVT and the Caprini score combined with D-dimer exhibit better diagnostic performance.

Dural arteriovenous fistulas represent a distinct direct pathological connection between dural arterial feeders of the meninges to cortical veins or sinuses. Vascular supply of the meninges is provided by a series of named arteries-anterior, middle, and posterior meningeal arteries, with the tentorium provided by the artery of Bernasconi and Cassinari (anterior-medial) and the artery of Davidoff and Schechter (posterior-medial). This case is the first report in the literature of a lateral distal posterior cerebral artery supplying the meninges and contributing dural feeders to a Cognard type III/Borden type III dural arteriovenous fistula.

To present a retrospective review of a single-institute experience with bypass surgery of complex anterior cerebral artery aneurysm. ⋯ We established a simplified surgical algorithm for complex anterior cerebral artery aneurysms based on the geometrical and spatial relationship between efferent arteries. The reasons for bypass failure and hemorrhagic complication were also discussed.

This study aimed to demonstrate the utility of power tools and intraoperative neuromonitoring of percutaneous pedicle screw (PPS) insertion (so-called PPS monitoring) by SINGLE-position surgery (SPS) after lateral lumbar interbody fusion. ⋯ Similar to previous reports related to power tools in the prone position, the lateral decubitus SPS technique can also use power tools to save PPS insertion time. Furthermore, we suggest that the use of PPS monitoring may prevent erroneous PPS insertions by using intraoperative computed tomography navigation in advance.

Novel Dural-Splitting Operative Technique for Excision of Ventrally Located Spinal Meningiomas.
Spinal meningiomas are one of the frequently seen intradural extramedullary spinal tumors. They are almost always World Health Organization grade I, and a complete removal of the tumor can be curative. However, ventrally located spinal meningioma removal can be challenging due to the position in front of the spinal cord through a narrow corridor provided by routine dorsal approaches. Incomplete excision of the relatively inaccessible dural attachment can consequently lead to recurrence. We describe a safe and reproducible technique used to achieve Simpson grade I removal of ventrally located spinal meningioma. ⋯ Its novel interdural approach can be used for all ages and all spinal meningiomas.
