Aim:
Traumatic intracranial aneurysm (TICA) is a rare vascular lesion with various etiologies and a high mortality rate when diagnosed late. In this study, we present our cases of TICA, which we treated with flow-diverter stents due to different etiological factors.
Methods:
Clinical data were recorded for 8 patients: age, gender, etiological factors, aneurysm location, aneurysm type, rupture, main artery status, and postoperative complications.
Results:
75% (n:6) of the patients were male and 25% (n:2) female. Etiologically, there was intracranial tumor surgery in 3 cases (37.5%), fall from height in 2 (25%), road accident in 2 (25%), and blunt trauma in 1 (12.5%). Reconstruction used a flow-diverting stent in all cases. One patient experienced intraoperative iatrogenic rupture of the distal arterioles due to a microwire. Mean angiographic follow-up was 17.8 months (range, 6-32 months). During follow-up, none of the patients required renewed endovascular treatment.
Conclusion:
Traumatic aneurysm is a vascular lesion with high mortality when diagnosed late. In case of suspected vascular injury after trauma or intracranial surgery, further evaluation should be performed without delay. TICA can be safely treated with flow-diverter stents, conserving the main artery.
