Treatment strategies for traumatic cervico-cranial pseudoaneurysms: A single institution experience

Limited clinical and angiographic data exists for patients with traumatic cervico-cerebral pseudoaneurysms. In this paper, we present our limited experience with various management strategies for traumatic cervico-cranial pseudoaneurysms.

We retrospectively analyzed 37 consecutive cases of traumatic pseudoaneurysms involving the cervico-cranial or the cerebral arteries diagnosed at our center from September 2009 to December 2014. The demographic data, etiology, clinical presentation, lesion location, treatment modality, and follow-up outcomes of these patients were reviewed. Among these 37 patients, 5 patients were treated by surgery, while 29 patients were treated by the endovascular approach and 3 received conservative treatment.

During the study period, 42 pseudoaneurysms were identified in 37 patients with a history of head or neck injury. Five patients underwent surgical exploration of the lesion with an uneventful postoperative course. Twenty-nine patients were treated by endovascular interventions with various embolization materials including coils, stents, detachable balloons, liquid embolic agents, and a combination of these agents. The angiographic follow-up imaging demonstrated complete exclusion of the aneurysm from the circulation with the patient being free from any additional neurological deficits.

Proper selection of an appropriate approach is essential to address the management of traumatic cervico-cerebral pseudoaneurysms. The treatment of traumatic cervico-cerebral pseudoaneurysms should be selected according to the location and the clinical features of the pseudoaneurysms. The endovascular treatment is a safe and effective modality and should be the first-line choice for treatment of traumatic pseudoaneurysms.
