Arteriovenous Malformations

Arteriovenous malformation (AVM) of the parasellar region. (a) Axial T2-weighted MR image. (b) Coronal contrast-enhanced CT image. Multiple tangles of the arteries and veins are present in the right parasellar region, indicating feeding arteries and draining veins of an AVM.

  • Noninvasive vascular imaging—CT angiography (CTA) or MR angiography (MRA)—can be used to confirm the diagnosis and is mandatory in planning for stereotactic radiosurgery.


  • The gold standard diagnostic technique for diagnosis and surgical treatment planning is cerebral angiography.






      60.3 Clinical and Surgical Management






      • The individualized treatment of AVMs in the sellar region depends heavily on the location and architecture of the particular malformation.


      • Emergent surgical intervention may be required for ruptured AVMs. Medical goals include blood pressure control.


      • AVMs may be managed with multimodality treatment including endovascular embolization, surgical resection, and/or stereotactic radiosurgery [2, 3].
