Vasospasm and resultant clinical deterioration caused by delayed cerebral ischemia (CD-CDI) are a considerable source of morbidity after aneurysmal subarachnoid hemorrhage (SAH). Although they are a relatively common cause of spontaneous SAH, AVM rupture and ensuing vasospasm are rarely reported. ⋯ Even in cases of SAH from AVMs, angiographic vasospasm after AVM rupture is relatively rare. We thus do not recommend empiric delayed angiography to assess for vasospasm in these patients. Nevertheless, it does remain a rare possibility and should be considered in those with CD-DCI.
