Definition n n Lesions of the cerebral vasculature develop such that blood flows directly from the arterial system to the venous system without passing through a capillary system. The arteriovenous (AV) shunt is the definitive characteristic of these lesions.
Pathophysiology The direct connection between the arterial and venous systems supplies a lowresistance shunt for arterial blood and exposes the venous system to abnormally high pressures. n This results in a system of enlarged feeding vessels, the tangled nidus of the AVM itself, and enlarged draining venous structures n
Etiology n AVMs are considered congenital lesions and are characterized by a failure of the embryonic vascular plexus to fully differentiate and develop a mature capillary bed in the affected area.
Clinical presentation n n n Hemorrhage (53%) ¨ Acute onset of severe headache ¨ May be described as the worst headache of the patient's life Seizure (46%) Headache (34%) Progressive neurologic deficit (21%) Hemorrhage is more likely to be caused by small lesions, while seizures are more likely to be caused by large lesions Pediatric patients ¨ Heart failure ¨ Macrocephaly ¨ Prominent scalp veins
Clinical presentation n n The annual risk of intracranial hemorrhages associated with AVMs is 2 -3%. The mortality rate associated with the initial bleed is 10%. The mortality rate associated with the second bleed is 13%, and the rate increases to 20% for each subsequent bleed. The incidence of new neurologic deficit occurring with each bleed is 50%.
Clinical presentation Approximately 7. 6% of patients with an AVM develop an aneurysm. n Alternatively, 1. 1% of patients with an aneurysm are found to have an AVM. n
Risk of hemorrhagic AVM Hemorrhage before n Increasing age n Deep brain location n Exclusive deep venous drainage n
Imaging studies n n n CT scan is the first imaging choice in an emergent setting MRI is the first imaging choice in a nonemergency setting (eg, workup of seizure, headache, or neurologic deficit). Magnetic resonance angiograms (MRAs) can reveal the anatomy of the AVM noninvasively but have lower resolution than conventional angiography. Cerebral angiography provides definitive diagnosis. CT angiography has improved dramatically and, in some cases, provides a less invasive alternative to catheter angiography
Treatment Endovascular neurosurgery n Surgery (craniotomy) n Stereotactic radiosurgery n Combination therapy n
