Abstract Background: Prior research by the authors studied objective impact on medical students’ academic course, perceived cognitive load, quantified subjective feedback while teaching using AnaVu, a low resource stereoscopic projection system. The qualitative data from opinions, and comparative educational results reported undergraduate students following their participation in (AnaVu) monoscopic learning sessions are explored this study. This study was done to evaluate compare...
A 52-year-old male with right carotid body tumor underwent direct percutaneous glue (n-butylcyanoacrylate [NBCA]) embolization. Several hours later, he developed left hemiparesis from embolization of the polymerized cast. Migration during is presumed to occur only in liquid state, which may lead stroke or cranial nerve deficits. To best our knowledge, this first report delayed a treated hypervascular head and neck.
OBJECTIVE The aim of this study was to investigate the utility a heavily T2-weighted volumetric MRI sequence (3D sampling perfection with application-optimized contrasts using different flip-angle evolutions [SPACE]) in feeder localization spinal dural arteriovenous fistula (SDAVF). METHODS Patients who were diagnosed SDAVF and had 3D SPACE source images available for review identified from retrospective medical records. A total 16 patients identified, MR analyzed separately by 2 blinded...
In patients with acute ischemic stroke large vessel occlusion, various angiographic features are important in patient selection and predicting outcome.We evaluated like collaterals, clot burden score, recanalization, number of passes, intracranial atherosclerotic disease (ICAD) the functional outcome at 90 days.This was a retrospective analysis prospectively collected data 163 occlusion who underwent mechanical thrombectomy within 24 hours symptom onset. Angiographic were reviewed blinded to...
To date, very little study of the importance a volumetric T2-weighted MR sequence in evaluation spinal vascular malformations (SVMs) has been carried out.To determine utility and accuracy T2 compared with conventional diagnosis SVMs.Retrospective analysis all patients who underwent DSA for suspected SVMs was conducted. Conventional images were analysed presence flow voids parenchymal changes, characterized. The sensitivity, specificity, overall diagnostic these MRI diagnoses calculated.Of 89...
<h3>BACKGROUND AND PURPOSE:</h3> Volumetric high-resolution heavily T2-weighted imaging or time-resolved contrast-enhanced MRA is used in the detection and characterization of spinal vascular malformations, though inherent trade-offs can affect their overall sensitivity accuracy. We compared efficacy volumetric images malformation diagnosis feeder assessed whether a combined evaluation improved accuracy diagnosis. <h3>MATERIALS METHODS:</h3> Twenty-eight patients with malformations (spinal...
Abstract Background: The authors had earlier studied the utility of stereoscopic projection neuroanatomic three-dimensional models through AnaVu (a low resource system) on medical students. tool was developed by collaboration between anatomy teachers, radiologists, and visualization experts. Although preliminary results indicated advantages in learning, perspective end users tool, not known hence this study. Methodology: A cross-sectional study observational nature conducted where Faculty...
The authors had previously developed AnaVu, a low-resource 3D visualization tool for stereoscopic/monoscopic projection of models generated from pre-segmented MRI neuroimaging data. However, its utility in neuroanatomical education compared to conventional methods (specifically whether the stereoscopic or monoscopic mode is more effective) still unclear. A three-limb randomized controlled trial was designed. sample (n = 152) 2022 cohort MBBS students at Government Medical College,...
The preoperative localization of the feeder spinal dural arteriovenous fistula (SDAVF) could simplify diagnostic angiographic procedure. Localization by non-contrast-enhanced MRI-based techniques is an attractive option. However, usefulness such approach for evaluation SDAVF has not yet been reported.To study impact non-contrast localization, followed targeted angiography, in before endovascular intervention.Prospectively collected data were analyzed and level was localized preoperatively....
Abstract Scalp arteriovenous malformations (AVMs) are rare extracranial vascular that traditionally treated by surgical excision or combined endovascular-surgical approaches. We describe percutaneous treatment of scalp AVM, using a new liquid embolic agent, SQUID. Because its nonadhesive property, prolonged injection and complete obliteration AVM is feasible. The cast formed aesthetically appealing to the patient, it may obviate need for further excision. It could be considered as primary...

Abstract Infrapopliteal pseudoaneurysms are rare and usually occur secondary to trauma. Though there no consensus regarding the management of same, endovascular treatment has become an alternate option open surgical management. In this report, we describe two cases posttraumatic infrapopliteal involving crural arteries. Both were managed successfully with stent graft placement complete exclusion pseudoaneurysm. Our results show that grafting is a good alternative repair in pseudoaneurysms,...
Direct carotid cavernous fistulae (CCF) are often detected early and treated promptly resulting in a paucity of literature regarding its long-term evolution. We present case high flow post-traumatic direct CCF that was neglected for over 6 years presented with rare manifestation primary intraventricular haemorrhage. Occlusions the venous outlets likely resulted engorgement deep system. The segmental anatomy shunting basal vein is critical to clinical presentation may range from ganglia or...
To report the intermediate and long-term clinical angiographic outcomes of treatment complex intracranial aneurysms with flow diverter (FD) stents.A tertiary care centre from south India.Patients treated FD stents were retrospectively analyzed. The demographics, technical success, angiographic, recorded.A total 13 patients underwent treatment, in whom 11 procedures successful. cohort included large or giant recurrent following conventional endovascular treatment. Major morbidity was observed...
