Microsurgical Management of Complex Meningiomas Involving Dural Venous Sinuses: Operative Techniques, Case Illustrations and Long-Term Outcomes in a Series of 70 Cases.

Background: Meningiomas involving the dural venous sinuses present unique therapeutic challenges. While gross total resection remains the mainstay of treatment for meningiomas, involvement of critical vascular structures may limit extent of resection and increase the risk of recurrence. Optimal management of meningiomas with venous sinus involvement has been discussed in the literature, with some advocating for subtotal resection with postoperative surveillance and radiation, if necessary, while others recommend total resection with reconstruction of resection of the involved sinus.

Current Indications, Trends, and Long-Term Results of 233 Bypasses to Treat Complex Intracranial Aneurysms: A Location-Specific Analysis.

We therefore sought to investigate the long-term results, current indications, and trends of bypasses for brain aneurysms.

Methods: We retrospectively reviewed bypasses performed between 2005 and 2022 to treat brain aneurysms.

Effect of Volatile Organic Compounds on Pulmonary Functions Among Paint Industry Workers of Unorganized Sectors.

Background Paint industry workers are constantly exposed to paints and organic solvents that contain a substantial quantity of volatile organic compounds (VOCs). Exposure to VOC emissions could result in pulmonary, neurobehavioral, and hematological consequences. Limited studies have been undertaken in India to assess the health consequences of VOCs among paint industry workers in unorganized sectors.

Ophthalmic artery reversal predicts contralateral body weakness symptoms better than carotid Doppler velocity-preliminary results.

Background: The measurement of blood velocity in the carotid artery has been the most popular noninvasive method of identifying and classifying carotid stenosis for half a century. Carotid stenosis is an indicator of elevated risk of stroke; anatomic revascularization reduces the chance of stroke by more than half. Controversy persists on how patients with severe carotid stenosis should be selected for anatomic revascularization.

High-Flow Bypass and Clip Trapping of a Giant Fusiform Middle Cerebral Artery (M1) Aneurysm: Technical Case Instruction.

Background And Importance: Giant intracranial aneurysms have a poor natural history with mortality rates of 68% and 80% over 2-year and 5-year, respectively. Cerebral revascularization can provide flow preservation while treating complex aneurysms requiring parent artery sacrifice. In this report, we describe the microsurgical clip trapping and high-flow bypass revascularization for a giant middle cerebral artery (MCA) aneurysm.

Orbitozygomatic Transsylvian and Subtemporal Transzygomatic Approaches for Clipping of Basilar Tip Aneurysms: 2-Dimensional Operative Video.

Indications Corridor And Exposure: The orbitozygomatic transsylvian approach is ideal for basilar tip aneurysms (BTAs) ≤15 mm located at or above the level of posterior clinoid process (PCP), whereas for larger, low-lying BTA's with fetal posterior cerebral artery (PCA), the subtemporal transzygomatic approach is preferred. Both approaches expose the basilar tip area and structures in the interpeduncular fossa from an anterolateral angle and the lateral angle, respectively.

Anatomic Essentials Need For Preoperative Planning And Assessment: Aneurysm size and level, brainstem perforators, and PCA size (fetal or not) should be noted preoperatively.
