Cerebrovascular Diseases Flashcards
What is a stroke?
What is an ischemic stroke?
What is an hemorrhagic stroke?
What is a global cerebral ischemia/hypoxia?
What is a focal cerebral ischemia?
Where is the borderline for watershed infarcts?
What are the types of ischemic strokes?
-emboli infarctions
-paradoxical emboli
-thrombotic occlusion
-lacunar infarcts
What are emboli infarctions? How do they cause ischemic strokes?
What are paradoxical emboli? How do they cause ischemic strokes?
What is a thrombotic occlusion ?
What is a lacunar infarcts?(high yield)(lenticulostruate)
Discuss the gross morphology of infarcts
What happens up to 24. Hours after an infarct?
What happens between 24 hrs to 2 weeks. Hours after an infarct?
What happens after 2 weeks Hours after an infarct?
What does a cerebral infarct look like on histology?
What are the types of intraparenchymal hemorrhage?
What is subarachnoid hemorrhage?
Discuss hypertensive hemorrhage
What is lipohyslinosis?
What are the causes of non-hypertensive intraparenchymal hemorrhage?
What is the epidemiology of arterio-venous malformations?
What are the clinical features and complications of arterio-venous malformations?
Describe the gross anatomy of arterio-venous malformations
Whaat is microscopically seen in arterio-venous malformations?
What usually causes subarachnoid hemorrhage?
Describe the morphology of berry aneurysms
What are the clinical features of subarachnoid hemorrhage?
What investigations for subarachnoid hemorrhages ? Subarachnoid is highyield(basal cistern is highyield)
What are the complications of subarachnoid hemorrhages? Nolidipine is high yield, will need to know about ca+ channel blockers and it crosses the blood brain barrier)
