Development of a predictive grading system for postoperative ischemia following middle cerebral artery aneurysm clipping.

The current study presents a single-surgeon experience with microsurgical clipping of middle cerebral artery (MCA) aneurysms and introduces a grading system to predict postoperative ischaemia. A retrospective analysis of 222 patients with 251 MCA aneurysms treated between 2015 and 2024 was conducted. Key factors, including aneurysm size, dome morphology, neck location, calcification, and rupture status, were evaluated to identify predictors of radiological infarction.

Preoperative coil localization for spinal surgery is accurate, safe and effective: a single-centre initial experience.

Objective And Study Design: This is a retrospective, descriptive study of consecutive patients undergoing novel preoperative pushable coil localization for spinal surgery, in order to evaluate its feasibility, safety and accuracy.

Methods: Consecutive patients who underwent pre-operative coil marking for spinal surgery at our institution from May 2018 to July 2021 were included. Data were collected for coil placement, accuracy, complications and fluoroscopy usage.

The utility of arterial spin labelled perfusion-weighted magnetic resonance imaging in measuring the vascularity of high grade gliomas - A prospective study.

Background: Dynamic susceptibility contrast (DSC) perfusion weighted imaging (PWI) currently remains the gold standard technique for measuring cerebral perfusion in glioma diagnosis and surveillance. Arterial spin labelling (ASL) PWI is a non-invasive alternative that does not require gadolinium contrast administration, although it is yet to be applied in widespread clinical practice. This study aims to assess the utility of measuring signal intensity in ASL PWI in predicting glioma vascularity by measuring maximal tumour signal intensity in patients based on pre-operative imaging and comparing this to maximal vessel density on histopathology.

Removal of Biomass and Nutrients by Weeds and Direct-Seeded Rice under Conservation Agriculture in Light-Textured Soils of North-Western India.

The escalating scarcity of irrigation water, transplantation of rice on light-textured soils and labour cost acted as major drivers for the transition towards direct-seeded rice (DSR) cultivation from the conventionally flooded transplanting system. Despite these advantages, DSR is a challenge in light texture soil due to heavy weed infestation and a slight decline in crop yield. The weeds compete for nutrients and have an adverse effect on the growth and yield of crops.

Early postoperative colonic ventriculoperitoneal shunt migration with trans-anal protrusion: A unique case report.

Introduction And Importance: Colonic ventriculoperitoneal shunt (VPS) migration with trans-anal protrusion remains uncommon. Patients may be asymptomatic, and diagnosis may only be made on visualization of the prolapsed catheter from the anus. This unique case of early post-operative trans-anal shunt protrusion highlight the possibility of this rare complication specially when shunt revision accompanies bowel surgery.
