Abstract W P53: Extracranial Traumatic Aneurysms Due to Blunt Cerebrovascular Injury

摘要: Background and Purpose: Traumatic aneurysms occur in about 10% of extracranial blunt traumatic cerebrovascular injuries (TCVI). The clinical consequences optimal management are poorly understood. Methods: A prospective systematic study TCVI at a Level I trauma center identified seven patients with 19 carotid or vertebral artery aneurysms. An additional six were followed outside the study. All treated aspirin 325 mg daily underwent follow up imaging beyond initial hospitalization. Endovascular treatment was reserved for demonstrating significant enlargement on follow-up imaging. Ischemic complications, aneurysm symptoms, appearance CT angiography (CTA) assessed. Results: cohort comprised 10.3% all TCVI. Two (15.4%) had an ischemic stroke. No patient experienced stroke new symptom following initiation antiplatelet therapy. Clinical radiographic CTA averaged 22.0 months (range 6.6-55.7 months). Ten 26 (38.5%) not visualized last CTA, 10/26 smaller, 1/26 (3.8%) unchanged, 5/26 (19.2%) larger. Saccular more likely to enlarge than fusiform (33.3 vs 11.8%). (both > 15 mm size) stenting. Conclusion: majority can be managed regimen serial have greater tendency grow when compared aneurysms. ![][1] [1]: /embed/graphic-1.gif
