Summary
Carotid artery injuries, often from gunshot wounds, require careful surgical management. Preoperative arteriography and techniques like extracranial-intracranial bypass improve outcomes and reduce neurologic deficits.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Cerebrovascular Medicine
Background:
- Carotid artery injuries are significant surgical emergencies.
- A majority of these injuries result from penetrating trauma.
Purpose of the Study:
- To review the management and outcomes of carotid artery injuries.
- To evaluate the efficacy of preoperative arteriography and specific surgical techniques.
Main Methods:
- Retrospective review of 54 carotid artery injury cases treated between 1975 and 1979.
- Analysis of injury mechanisms, affected carotid artery segments, associated injuries, and treatment modalities.
Main Results:
- Gunshot wounds accounted for 78% of injuries; internal carotid artery was involved in 33%.
- Mortality rate was 10%, with 4% directly due to vascular trauma.
- Extracranial-intracranial (EC-IC) bypass was performed in 7 patients, with 86% achieving normal neurologic status.
Conclusions:
- Preoperative arteriography is recommended for optimal surgical planning.
- EC-IC bypass is effective for intracranial carotid artery injuries, reducing neurologic deficit risk.
- Carotid artery ligation is a suitable treatment for severe neurologic deficits.
