Vestibular schwannoma (VS) surgery requires appropriate patient selection, meticulous microsurgical technique and optimal post-operative care. Focused radiation is an effective alternative for the treatment of smaller VSs. For VS surgery to remain a reasonable option, surgery must be performed with a limited number of complications. Complication rates for VS surgery have increased over the last decade. This is likely due to (1) decreased surgical volume and as a result decreased microsurgical experience, (2) larger tumors undergoing surgery while smaller tumors are reserved for radiation, and (3) surgery for previously radiated tumors resulting in more difficult anatomic dissection. Appropriate management of complications is paramount. Herein, we discuss complications related to VS microsurgery and methods of avoidance. Specifically, we discuss the most frequently encountered complications, intraoperative monitoring and finally, methods of addressing these complications. With meticulous microsurgical technique, careful intraoperative monitoring and vigilant perioperative care one will ensure optimal patient outcomes.

Resection of a ventrally located ossified thoracic spinal meningioma: illustrative case.
J Neurosurg Case Lessons
January 2025
Division of Neurosurgery, Department of Surgery, Hospital Ignacio Pirovano, Buenos Aires, Argentina.
Background: Resection of calcified meningiomas in the ventral thoracic spinal canal remains a formidable surgical challenge despite advances in technology and refined microsurgical techniques. These tumors, which account for a small percentage of spinal meningiomas, are characterized by their hardness, complicating safe resection and often resulting in worse outcomes than their noncalcified counterparts.
Observations: The authors present the case of a 68-year-old woman with a ventrally located ossified meningioma at the T9-10 level, successfully treated via a posterolateral transpedicular approach.
Single-Stage Microsurgical Clipping of Multiple Intracranial Aneurysms in a Patient with Cerebral Atherosclerosis: A Case Report and Review of Surgical Management.
J Clin Med
January 2025
Department of Neurosurgery, "Carol Davila" University of Medicine and Pharmacy, 050474 Bucharest, Romania.
The management of multiple intracranial aneurysms presents significant clinical challenges, particularly when complicated by underlying conditions such as cerebral atherosclerosis. This case report highlights the successful treatment of a 66-year-old female diagnosed with three intracranial aneurysms located in the right middle cerebral artery (MCA), pericallosal artery, and M2 segment. The patient also had a history of systemic atherosclerosis and right-sided breast cancer, factors that increased the complexity of surgical intervention.

Soft tissue reconstruction in the lower limbs presents a significant challenge, particularly when addressing defects in the distal third of the leg, ankle, and foot. The reverse sural flap reliant on the perforating branches of the peroneal artery has emerged as a versatile option, offering a solution for patients for whom microsurgical techniques are not feasible. Despite its advantages, the procedure carries inherent risks, especially in populations with underlying conditions, such as venous insufficiency, cardiovascular disease, and diabetes, as well as in elderly patients, where the likelihood of flap necrosis is elevated.

Objective: To evaluate the surgical outcomes of delayed microsurgical clipping for ruptured intracranial aneurysms (RICAs) of anterior circulation.
Methods: This retrospective, cross-sectional study assessed the surgical outcomes of 50 patients who underwent surgical clipping for "ruptured aneurysms" with subarachnoid haemorrhage after the 21 post-bleed day, from May 01, 2022, till May 01, 2023, at the Department of Neurosurgery, Punjab Institute of Neurosciences, Lahore, Pakistan.
Results: The mean age of patients was 49.
A detailed analysis of the penile fibro-vascular assembly.

Microsurgical Potency Reconstruction Center, Shu-Tien Urology Ophthalmology Clinic, Taipei 10662, Taiwan.
Article Synopsis
- The study investigates the penile fibrovascular assembly to determine if it functions as an independent vascular compartment within the human body, addressing a gap in cardiovascular research.
- Researchers examined 23 male cadavers and analyzed extensive medical imaging and hemodynamic data to gain insight into the structure and function of the penile vasculature.
- Results indicate that the human penis contains a unique bi-layered fibrovascular assembly with atypical vascular patterns, challenging previous assumptions about penile venous drainage.
