Surgical Management of Meningiomas Involving the Torcula, Transverse Sinus, and Jugular Bulb: A Technical Note and Review of the Literature.

Meningiomas that invade the confluens sinuum are rare and require extensive preoperative planning. Here, we describe the surgical and radio-oncological management of an aggressive large occipital meningioma invading the superior sagittal sinus, torcula, right and left transverse sinus down to the level of the jugular bulb in a 21-year-old female patient. Details of the surgical approach are presented to highlight the planned staged resection of this tumor at the level of the torcula to initially debulk the lesion while preserving venous outflow through the patent's sinus.

Pharmacoprophylaxis for Venous Thromboembolism in Spinal Surgery: A Systematic Review and Meta-analysis.

Objective: Venous thromboembolism (VTE) is a significant contributor to postoperative morbidity and mortality. Prophylactic regimens for VTE involve mechanical prophylaxis and pharmacoprophylaxis. This systematic review and meta-analysis aimed to determine the efficacy and safety of pharmacoprophylaxis in comparison with any nonpharmacoprophylaxis regimen for the prevention of postoperative VTE in patients undergoing spinal surgery.
