Intracranial arterial vasospasm is an important consequence of subarachnoid hemorrhage. In posttraumatic patients, this phenomenon is becoming increasingly recognized with noninvasive techniques that evaluate (1) vascular stenosis, such as transcranial Doppler (TCD) ultrasound, and (2) regional cerebral blood flow, such as single‐photon emission computed tomography (SPECT). A posttraumatic patient developed symptomatic vasospasm that was detected by TCD and SPECT and then treated with percutaneous transluminal balloon cerebral angioplasty, which improved the symptoms. The anatomical and functional results of angioplasty were evaluated also by TCD and SPECT, which showed a reduction in the severity of stenosis and improved blood flow, respectively.
