Interventional Radiology - The Stroke Patient
The role of interventional radiologists in the management of stroke patients.
General - Cerebrovascular Incident (CVA)
In a cerebrovascular accident (CVA), there is an acute interruption of blood supply to the brain (due to occlusion or rupture). This is also known as a stroke. CVAs can be divided into two main groups:
- Ischemic CVA
- Blood flow is blocked by a thrombus (clot formed within blood vessels) or an embolus (clot/air bubble/fat particle formed elsewhere, dislodged, and eventually reaching cerebral circulation).
- Important causes: atherosclerosis, atrial fibrillation.
- Risk factors: hypertension, smoking, coagulation disorders, diabetes mellitus
- Hemorrhagic CVA
- Bleeding in or around the brain parenchyma due to a ruptured blood vessel. Hemorrhagic CVA can be further subdivided into intracerebral hemorrhages and subarachnoid hemorrhages (SAH)
- Important causes/risks: hypertension, cerebral amyloid angiopathy, anticoagulants, blood vessel anomalies, venous sinus thrombosis, vasculitis
