A Patient with Bacterial Bilateral Cervical Aneurysms Who Responded to Endovascular Treatment

Abstract

Objective: We report a case involving a patient in whom endovascular treatment for bilateral bacterial cervical aneurysms led to a favorable outcome. Case Presentation: A 67-year-old male was diagnosed with bilateral bacterial cervical aneurysms during treatment for infectious endocarditis, and was referred to our hospital. Contrast-enhanced CT revealed aneurysms around the bifurcations of the bilateral carotid arteries. Antibiotic administration did not reduce the aneurysms, and endovascular treatment was performed. Stenting was conducted in the bilateral carotid arteries, and there was a marked reduction in the right aneurysm size. However, the left aneurysm was only transiently reduced and reappeared. Coil embolization was performed, leading to the disappearance of the left aneurysm. Conclusion: Endovascular treatment may be an option for bacterial cervical aneurysms.
