Cerebrovascular Accident by Dr. Lawrence S Siamuyoba - Department of Internal Medicine/Haemato-oncology

Description

This comprehensive lecture on cerebrovascular accidents, authored by Dr. Lawrence S Siamuyoba, Senior Registrar in the Department of Internal Medicine and Haemato-oncology, provides a detailed overview of stroke and transient ischaemic attacks (TIAs). The presentation begins by clearly defining key terms, differentiating between TIAs as transient deficits and strokes as lasting neurological impairments. It covers the etiology of TIAs, including cardiac emboli, carotid artery disease, and hematologic disorders, and outlines major risk factors such as hypertension, smoking, and diabetes. The lecture then details the two primary types of stroke: ischaemic (thrombotic and embolic) and haemorrhagic (subarachnoid and intracerebral). For each type, it explains the specific pathophysiology, characteristic clinical presentations—such as the gradual onset of thrombotic strokes versus the abrupt onset of embolic or haemorrhagic events—and the critical steps in diagnostic evaluation, emphasizing the role of CT imaging. Management strategies are thoroughly discussed, including acute interventions like thrombolysis for ischaemic strokes within the therapeutic window, blood pressure control, anticoagulation, antiplatelet therapy for secondary prevention, and the management of cerebral oedema. The material also addresses the specific medical and surgical approaches for subarachnoid and intracerebral haemorrhages. This resource is essential for medical students, postgraduate trainees in neurology, internal medicine, and emergency medicine, as well as practicing clinicians seeking to solidify their understanding of the rapid assessment, diagnosis, and evidence-based management of acute cerebrovascular events. It serves as a vital study and reference guide for mastering this critical area of clinical medicine. Review this detailed presentation to enhance your diagnostic and therapeutic skills in stroke care.
