Human anatomy is a three-dimensional subject that requires a clear understanding of the relationships between structures through the study of human cadavers, microscopic samples, and models. Objective: This study aimed to examine the attitudes and perceptions of students regarding teaching anatomy before and after the lockdown period and ways of improving the challenges they faced. Methods: This cross-sectional study was conducted at AL Imam University School of Medicine. Structured surveys were designed to understand students' attitudes and opinions towards offline versus online teaching of anatomy and suggestions to improve the online teaching process. Results: The mean attitude scores for the conventional lectures, seminars, and practical sessions were significantly higher. Students expressed positive attitudes towards the three teaching modules. Students agreed that themes related to computer skills and technical Internet infrastructure (71.55%) and administrative procedures (61.74%) are essential for improving the online teaching process. Conclusion: Conventional learning is the main target of student learning. Improvements in computer skills, technical Internet infrastructure, learning resources, staff communication, examinations, and development of blended learning will enrich the learning process, especially during the impending challenges.

On the other hand, final infarct volumes are predictive of outcomes. We sought to explore the relationship between final infarct volumes and outcomes in octogenerians with acute stroke due to M1 MCA occlusion treated with endovascular therapy at our institution. Methods: Retrospective analysis of an acute stroke endovascular database was performed. Inclusion criteria were acute M1 MCA occlusion and post procedural MRI allowing for final infarct volume analysis through an automated software application. Results: A total of 219 patients were identified of which 51 (23%) were 80 years or older. Median age in non-octogenerians was 65.5 versus 83 in octogenerians. Females were 51.8% versus 67%, respectively. Median admission NIHSS was 16 versus 17 (p=ns). Median final infarct volume was 43.6 cc vs. 43.3 cc (p=ns). Median time to treatment was 5.6 hours ver...

We sought to determine relationship between recanalization, clinical outcomes, and final infarct volumes in AIS patients presenting with middle cerebral artery (MCA) occlusion who underwent endovascular therapy and post procedure Magnetic Resonance Imaging (MRI). Methods: We identified 201 patients with MCA occlusion. Patients with other occlusive lesions were excluded. Baseline clinical/radiological characteristics, procedural outcomes (including Thrombolysis in Myocardial Infarction -TIMI scores), clinical outcome scores (modified Rankin scores - mRS), and final infarct volumes on Diffusion Weighted Imaging (DWI) were retrospectively analyzed from a prospectively collected database. Favorable outcome is defined as 90-day mRS≤2. Results: Successful recanalization (TIMI grade 2/3) was achieved in 83% and fa...

While final infarct volumes have been shown to correlate with outcomes in anterior circulation strokes, no such relationship has been described in basilar artery occlusions. We sought to determine the relationship between the volume of final infarction, location of infarction and outcome of clinical course in patients treated with endovascular therapy for basilar artery occlusion at our institution. Methods: A retrospective review of our prospectively maintained endovascular stroke database identified 103 patients of which 59 patients underwent post treatment MRI. Automated software was used to measure infarct volume. Results: Patients included in the study had the following features: mean age 61, mean NIHSS 20, female 24%. Successful recanalization (TIMI 2/3) occurred in 53/59 patients (90%). Infarcts were divided i...

The technique involves advancing a large bore catheter into the thrombus and manually aspirating through a syringe. We have previously reported our experience with nearly 200 patients, however most cases involved the use of an adjunctive device such as the MERCI retriever to facilitate clot disruption or advancement of the catheter through the tortuous carotid siphon. This selected case series represents those patients treated with MAT alone. Methods: The University of Pittsburgh acute stroke database was retrospectively reviewed to evaluate those patients presenting with a large vessel intracranial occlusion who were treated with MAT. The decision to treat was based on the amount of brain still considered at risk based on CT, CTP, or MRI, and not on time from onset. Patients were excluded if an adjunctive device was used to facilitate catheter advancem...

However, the importance of specific location of infarct within the MCA territory has not been described. We sought to assess the predictive value of specific topographic regions as predictors of outcomes in a homogeneous cohort of patients treated with endovascular therapy of M1 occlusive disease who underwent post procedure MRI. Methods: A retrospective review of our prospectively maintained single center endovascular database was performed. Automated software was used to measure infarct volume and the DWI ASPECT score was assessed by visual inspection using standard templates. Univariate and multivariate analysis was performed to determine predictors of favorable outcomes using each of the 10 regions as part of the ASPECT score as well as total ASPECT score. Results: 100 patients were identified. 56% were f...
