[Considerations when handling common acute intracranial vascular anomalies].

Conditions involving intracranial vascular anomalies are increasingly diagnosed, not least incidentally, with the increasing availability of neuroradiological investigations. Acute deterioration and development of symptoms due to a vascular condition could require neurosurgical intervention depending on the nature of the condition and status of the patient. On the other hand, asymptomatic patients with incidental findings require careful consideration and risk assessment when deciding on whether or not to treat the condition, and if so, how. In this review article we provide a summary of some of the most common neurosurgical vascular conditions and outline management considerations in both the acute and elective setting.
