Comparative Analysis of Tailored Minicraniotomy versus Standard Pterional Craniotomy in the Treatment of Anterior Circulation Aneurysms: A Single-Center Case-Control Observational Study.

Introduction: Multiple minicraniotomies (Mct) have been proposed as alternatives to standard pterional craniotomy (Pct) for intracranial aneurysm treatment. These approaches offer limited surgical corridors and distinct working angles, posing challenges in addressing all aneurysm types with one method. We suggest a tailored Mct technique, comprising three minimally invasive approaches targeting anterior circulation aneurysm sites (middle cerebral artery, internal carotid artery, anterior communicating artery).

Comparative Efficacy of Percutaneous Laser Disc Decompression (PLDD) and Conservative Therapy for Lumbar Disc Herniation: A Retrospective, Observational, Single-Center Study.

Although percutaneous laser disc decompression (PLDD) has been proposed as an alternative to conventional surgery for lumbar disc herniation (LDH), we specifically propose it for patients with contained herniations where standard surgical intervention is not the first option. This study evaluates PLDD compared to conservative therapy as an early treatment alternative. : This retrospective observational study compared PLDD to conservative treatment in adult patients with contained LDH.

This report discusses a case where the dual-lumen catheter system, an innovative neurosurgical tool integrating continuous irrigation with drainage, was employed.

Pedicled multifidus muscle flaps to treat dural tears due to penetrating spinal stab wounds: Two case reports and a literature review.

Background: Penetrating spinal injuries occasionally lead to dural tears (DT) and cerebrospinal fluid (CSF) leaks that risk both infectious and neurological complications. Here, we reviewed two cases and the literature regarding the safety/efficacy and limitations of repairing traumatic DT utilizing pedicled multifidus muscle flaps.

Case Description: Two males, ages 73 and 50, presented with Brown-Sequard syndromes and DT/CSF fistulas attributed to knife-induced spinal injuries at the D3-D4 and D11-D12 levels.

Trascallosal bilateral transforaminal resection of a solid partially calcified colloid cyst: 2D operative video.

Background: Colloid cysts are benign lesions of the roof of the third ventricle, often diagnosed incidentally; sometimes they can cause hydrocephalus due to obstruction of the foramina of Monroe. Symptomatic cysts could be resected either microsurgically (transcallosal or transcortical) or endoscopically. Although both strategies are effective and have advantages and disadvantages, there is no consensus on the choice of the optimal approach.

Single thalamic localization of brain toxoplasmosis mimicking brain tumors: Radiological and clinical findings.

Background: Cerebral toxoplasmosis is a relatively rare disorder that usually affects immunocompromised patients. The most common scenario occurs among human immunodeficiency virus (HIV)-positive patients. In those patients, toxoplasmosis is the most frequent cause of expansive brain lesion and continues to cause elevated morbidity and mortality.
