Activity Description

Arteriovenous malformations (AVMs) are abnormal fistulas between arteries and veins without an intervening capillary bed. High arterial flow directly into venous structures can lead to disruption of the venous walls and ultimately cause fatal hemorrhage. Intracranial AVMs are most commonly diagnosed during evaluation for an acute intracerebral hemorrhage but may be incidental findings uncovered during the assessment of conditions such as chronic headaches and seizures. Interventions for AVMs of the central nervous system are associated with increased mortality rates; risk stratification for surgical versus nonsurgical treatment is critical. 

Spinal AVMs most often present with progressive back and leg pain accompanied by neurologic deficits secondary to mass effect or ischemic injury; an acutely hemorrhagic presentation is also possible. Preventing the acute hemorrhage of a central nervous system AVM and subsequent neurologic injury requires an accurate diagnosis and the timely intervention of a multidisciplinary team.

This activity for healthcare professionals reviews the etiology, epidemiology, pathophysiology, clinical presentation, evaluation, and management of central nervous system AVMs. The activity also highlights the critical role of the interprofessional team in improving outcomes for patients with these congenital vascular lesions.


Target Audience

This activity has been designed to meet the educational needs of physicians.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Identify patients who may have a ruptured or unruptured arteriovenous malformation of the central nervous system based on their clinical presentation.

  • Determine the most appropriate imaging study for a patient with a suspected arteriovenous malformation of the central nervous system.

  • Apply the Spetzler-Martin Arteriovenous Malformation Grading System into clinical practice as a decision-making guide when determining the most appropriate intervention for a patient with an intracranial arteriovenous malformation. 

  • Develop and implement effective interprofessional team strategies to improve outcomes for patients with ruptured and unruptured arteriovenous malformations of the central nervous system.
