Summary
Traumatic internal carotid artery aneurysms are rare but can cause severe bleeding. A microvascular anastomosis can prevent deficits when ligating the carotid artery is necessary.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Trauma Surgery
Background:
- Traumatic infraclinoidal aneurysms of the internal carotid artery (ICA) are rare vascular lesions.
- These aneurysms can result from craniocerebral trauma and may lead to delayed, life-threatening hemorrhage into the nasopharyngeal space.
Observation:
- Patients may present with delayed rupture bleeding months after the initial injury, often requiring acute ENT ward admission.
- Diagnosis is confirmed via angiography, which is crucial for assessing cerebral collateral circulation.
Findings:
- In cases of inoperable aneurysms requiring internal carotid artery ligation, extra-intracranial microvascular anastomosis offers improved protection against postoperative neurological deficits.
- Five patients with infraclinoidal aneurysms were successfully treated with this technique over five years, including two with traumatic aneurysms.
Implications:
- This surgical approach provides a safeguard against deficits in complex ICA aneurysm cases.
- The successful application of extra-intracranial microvascular anastomosis highlights its potential in managing rare traumatic ICA aneurysms.
