Surgical Treatment of Metallic Foreign Body Embolization in the Middle Cerebral Artery: Case Report and Literature Review.

Abstract

Intracranial artery embolization cases caused by foreign bodies are extremely rare clinically. Twenty-four cases in total have been reported in the literature; among them, 20 cases were caused by firearms, and only 4 cases originated from nonfirearm injuries in daily life. We report a fifth case of foreign body embolization in the cerebral artery caused by nonfirearm injuries. We used microsurgery and successfully removed the metal piece that embolized the middle cerebral artery of a 30-year-old male patient in our center. Based on our experience, as well as on the premise that the surgical technique is mature and the medical facilities are well equipped, such patients should undergo embolectomy as soon as possible to avoid severe cerebral hemorrhage due to mechanical injury and vascular wall corrosion.
