Abstract：Objective To summarize the experience in diagnosing and treating intracranial multiple pseudoaneurysms with the help of DSA, CT and MRI images fusion combined with neuronavigation. Method The clinical data of 1 patient with traumatic intracranial multiple pseudoaneurysms were analyzed, including medical history, symptoms, signs, imaging examination, operative process and pathological results. Results The patient was a woman of 25 years and admitted to our hospital due to multiple traumas induced by a traffic accident. The preoperative DSA showed two intracranial pseudoaneurysms, which were on the second segment of the left anterior cerebral artery (A2) and pericallosal artery respectively. The pseudoaneurysm responsible for the cerebral hemorrhage was determined by preoperative DSA and CT images fusion. The pseudoaneurysms were accurately positioned by DSA and MRI images fusion. The complete resection of two aneurysms was achieved by one stage neuronavigatpr-assisted surgery. The postoperative pathological examination showed that the two aneurysms were traumatic pseudoaneurysms. Conclusions DSA and CT images fusion can help the surgeon to determine the aneurysm responsible for the intracranial hemorrhage. Inputting of DSA and MRI fusion images into the neuronavigation system is very helpful to surgery for the deep brain lesions which are not treated by endovascular embolization.
