Objective:
To develop the principles for the treatment of traumatic intracranial aneurysms after combat damage to skull and brain.
Material And Methods:
There were 18 patients with traumatic intracranial aneurysms from February 2022 to the present. Of these, 15 ones had gunshot penetrating wounds of the skull and brain. In 3 cases, aneurysms developed after explosive injury. All patients underwent computed tomography (CT) of the brain, CT angiography of brain vessels and selective cerebral angiography. We analyzed nature of brain damage, trajectory of the wounding projectile and aneurysm location to determine predictors of traumatic intracranial aneurysms. Surgical treatment was performed in all cases.
Results:
Hemorrhagic manifestations were observed in 11 patients. In 4 cases, traumatic intracranial aneurysms were diagnosed before rupture. Blunt head injury was followed by subarachnoid hemorrhage in 2 cases and ischemic stroke in 1 case. Endovascular or microsurgical intervention was performed depending on location of aneurysm, clinical manifestations and severity of brain damage. In case of distal aneurysms, endovascular and microsurgical destructive interventions prevailed. At the same time, proximal aneurysms (within or below the circle of Willis) required reconstructive endovascular treatment.
Conclusion:
Traumatic aneurysms should be suspected in all patients with penetrating craniocerebral injuries. Follow-up is contraindicated for traumatic intracranial aneurysms due to high risk of hemorrhage.
