Approximate Synonyms
  • Anomaly of cerebral arteriovenous system
  • Cerebral arteriovenous malformation
  • Congenital cerebral arteriovenous malformation (at birth)
Clinical Information
  • An abnormal connection between arteries and veins characterized by the absence of intervening capillaries in the brain. Signs and symptoms include headaches, bruit upon headl examination, seizures, and bleeding. When bleeding occurs, the signs and symptoms are similar to those in stroke.
  • Congenital vascular anomalies in the brain characterized by direct communication between an artery and a vein without passing through the capillaries. The locations and size of the shunts determine the symptoms including headaches; seizures; stroke; intracranial hemorrhages; mass effect; and vascular steal effect.
Present On Admission
POA Help
"Present On Admission" is defined as present at the time the order for inpatient admission occurs — conditions that develop during an outpatient encounter, including emergency department, observation, or outpatient surgery, are considered POA.
  • Q28.2 is considered exempt from POA reporting.
