OBJECTIVE: Traumatic pseudoaneurysms are rare but life-threatening lesions. We
investigated the patients with these lesions to clarify their clinical
characteristics and therapeutic strategies and we also reviewed the literatures
on the treatment principles, possible options, and outcomes. METHODS: There were
a total of 8 patients who were treated with traumatic intracranial
pseudoaneurysms between April 1980 and January 2009. Medical charts and the
imaging studies were reviewed for analysis. The outcome was measured with
modified Rankin Scale (mRS) score at 6 months after treatment. RESULTS: All 8
patients were male and the mean age was 25 years old. Six of those were located
at the cavernous segment of the internal carotid artery (ICA) and the other 2 was
located at the M2 segment of middle cerebral artery. The causes of trauma were
car accidents in 6, penetrating injury through the orbit in 1, and slip down
injury in 1 patient. Massive epistaxis or hematemesis occurred in all patients
with a pseudoaneurysm at the cavernous and ophthalmic segment of the ICA. All 6
patients of the cavernous and ophthalmic ICA group showed favorable outcome of
mRS 0 to 1. The outcome of patients with middle cerebral artery pseudoaneurysm
was mRS 2 to 3. CONCLUSION: Upon prompt diagnosis and proper treatment planning,
it is possible to achieve favorable outcome in these patients. Lesions located at
the cavernous segment of the ICA favored endovascular treatment while those at
the middle cerebral artery favored surgical treatment.
