Template:Ischemic Stroke Cause
Ischemic stroke causes (87%)
- Thrombotic (80% of ischemic CVA)
- Atherosclerosis
- Vasculitis
- Vertebral and carotid artery dissection
- Often preceded by yoga, spinal manipulation, coughing, vomiting
- Polycythemia
- Hypercoagulable state (oral contraceptives, antiphospholipid antibodies, protein S and C deficiencies, sickle cell anemia)
- Infection
- Toxicologic exposure (cocaine, amphetamines, etc.)
- Embolic (20% of ischemic CVA)
- Valvular vegetations
- Mural thrombi
- Arterial-arterial emboli from proximal source (ex. amaurosis fugax -> emboli from a proximal carotid artery plaque embolizes to the ophthalmic artery, causing transient monocular blindness)
- Fat emboli
- Septic emboli
- Hypoperfusion
- Cardiac failure resulting in systemic hypotension
- Cryptogenic
- Cryptogenic Stroke (CS) is defined as an Ischemic stroke of obscure or unknown origin. Its causes are unknown. It is transitory or reversible.[1]
