Abstract：

Objective To study the clinical characteristics, neuroradiological manifestations of mirror - image aneurysm of middle cerebral artery (MCA) and effects of microsurgical management.Method The clinical data of 9 cases with 18 mirror - image aneurysms of MCA which underwent microsurgical operation were analysed retrospectively. The mirror - image aneurysms of MCA were treated through the method of combining early - stage with select - stage operation and one - stage with two - stage operation. The operating principle was the ruptured aneurysm performed treated first and the unruptureed aneurysm performed treated second. Results Seventeen aneurysms were clipped directly and one aneurysm did not treat. Surgical outcome were good in 6 cases, light disability in 2 cases and severe disability in 1 case. Conclusions It can help to determine the responsibility aneurysm of ruptured aneurysms if the mirror - image aneurysm of MCA had been divided into Ⅰ model ( perfectly symmetry model ) and Ⅱ model ( in perfectly symmetry model). The surgical outcome were predominance if the mirror -image aneurysm of MCA performed microsurgical operation.

Objective To study the clinical features and surgical management of intracranial thrombotic giant aneurysms.Methods A retrospective study was performed for 11 patients with intracranial thrombotic giant aneurysms.The clinical presentation, clinical classification, surgical approaches and therapeutic efficacy were reviewed.Results The treatment included thrombectomy - aneurysm clip reconstruction in 9 cases, thrombectomy - aneurysm isolate in 1, and cervical internal carotid artery ligation in 1.The postoperative DSA or CTA showed that complete angiographic obliteration was achieved in 10 cases.Follow - up period was from 3 months to 6 months, the clinical outcomes of these patients were evaluated by Glasgow Outcome Scale grades.GOS of 8 cases were improved.There were minor deficit in 1 case, major deficit in 1 and one death.Conclusions The surgical treatment for intracranial thrombotic giant aneurysms is very difficult.It is a good method to occlude the parent artery temporally, eliminate intraaneurysmal thrombus and reconstruct parent artery.Intraoperative microvascular Doppler sonography (MVD) monitoring is helpful.     

Pediatric intracranial aneurysms——clinical characteristics and therapeutic strategies

Objective To assess the radiological characteristics and therapeutic strategies of intracranial aneurysms in children. Methods From our dedicated neurovascular databank of patients, we reviewed 23 consecutive children who had 24 intracranial aneurysms. There were 14 boys and 9 girls with a mean age of 9.09 years ( range 1 - 14 years ). Results Intracranial aneurysms in children ≤ 14 years constituted 1.3% of all intracranial aneurysms. Internal Carotid artery (ICA) and middle cerebral artery (MCA) were the most frequent sites for aneurysms. About 58.3% of the aneurysms were complex, including dissecting, pseudoaneurysm, giant and fusiform aneurysm. 1/3 of all aneurysms were located in posterior circulation. Only 1 case had multiple aneurysms in this case series. Almost half of all cases presented with subarachnoid hemorrhage and others presented with mass effect. 14 cases underwent endovascular treatment. 4 patients received microsurgical therapy. 5 cases did not receive microsurgical or endovascular therapy, 2 of them whose aneurysms spontaneously thrombosed during follow up. One boy with left vertebral artery giant aneurysm died after endovascular therapy owing to gradual thrombosis in basilar artery. Another child had poor outcome because of rerupture of aneurysm before operation. Whereas the majority had a favorable outcome. Conclusions Intracranial aneurysms in children had many clinical and radiological characteristics different from those in adults : ( 1 ) remarkable male predominance; ( 2 ) ICA and MCA were the most common sites for aneurysms; (3) high incidence of large, traumatic, infectious, dissecting and fusiform aneurysms. (4)For pediatric intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. Endovaacular therapy was the best choice for complex aneurysms.
