颅内夹层动脉瘤血管内栓塞治疗

Objective To analyze the clinical features of intracranial dissecting aneurysm and summarize the experience of its endovascular embolization. Methods 16 cases of intracranial dissecting aneurysm were treated by endovascular embolization. Among these 16 patients, 3 patients were treated with single stent or double stent placement technique, 9 patients were treated with stent- assisted coil embolization technique, 3 patients were ball artery occluded using the balloon - assisted or coil - assisted technique, and 1 patient was treated by simple coil embolization. Results Out of the 16 patients, 9 cases were completely occluded ( including parent artery occlusion cases ), 3 cases were subtotally occluded, 4 cases were incompletely occluded ( including cases of stent implantation ). Followed up for 6 months to 3 years, in addition to 1 case of early death, GOS evaluation results were respectively: grade Ⅰ 8 cases, grade Ⅱ 4 cases, grade Ⅲ 2 cases, grade Ⅳ 1 case. Cerebral angiography was carried out in 8 follow - up patients. No recurrence was watched in 7 cases, aneurysm neck recanalization was watched in 1 case, follow up was continued. Conclusion According to different localization of intracranial aneurysm and different pathological features, different methods of endovascular embolization are selected. It is the safe and effective treatment of dissecting aneurysm.

血管内栓塞治疗颅内动脉瘤时间窗的临床评价

Objective To evaluate the effects of endovascular embolization treatment for intracranial aneurysms in different time. Methods To respectively analyse the clinical data of 165 cases of ruptured intracranial aneurysm treated by endovascular treatment. The patients were divided into 3 groups accrodding to the time of treatment, endovascular reatments were stated within 24 h in group A, 3 d in group B and after 3 d in group C. The outcomes and complications including rebleeding, vasospasm and hydrocephala of 3 groups were compared. Results The incidence of rebleeding, vasospasm and hydrocephala in group A and B were lower than that in group C ( P ＜ 0. 01 ). Vasospasm in group C was most severe. The GOS score was highest in group A and lowest in group C. Conclusion Endovascular embolization treatment is a safe and effective method for treatment of intracranial aneurysm. The timing of treatment is a major factor for technical success.

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.
