Is proliferation activity significantly elevated in partially embolized cerebral arteriovenous malformations?
Increased proliferation activity in partially embolized AVMs supports a 'no-touch' strategy and clinical observation in high-risk AVMs and demands complete AVM elimination in treatable lesions.
Patients with unstable transient ischemic attacks immediately after onset of clinical symptoms are at high risk for subsequent stroke - they may benefit from Stroke Unit management and potential early thrombolysis once they develop strokes.
