Study Notes
Etiology of Ischemic Stroke
-
Thrombotic occlusion:
- Small vessel (lacunar) stroke
- Large vessel thrombosis
-
Embolic occlusion:
- Artery-to-artery: Carotid bifurcation, aortic arch, arterial dissection
- Cardioembolic: Atrial fibrillation, mural thrombus, myocardial infarction, dilated cardiomyopathy, valvular lesions, mitral stenosis, mechanical valve, bacterial endocarditis
- Paradoxical embolus: Atrial septal defect, patent foramen ovale
- Venous sinus thrombosis
- Subarachnoid hemorrhage due to vasospasm
