Abstract：

Objective To study the clinical characteristics and microsurgical skills of intracranial mirror-image aneurysm. Methods The clinical data and post-operative outcomes of 17 patients with 36 intracranial mirror-image aneurysms who underwent microsurgical operation were analyzed retrospectively. Results Thirty-five aneurysms were clipped directly and 1 did not give any treatment. One-time surgery was performed in 9 patients and 20 aneurysms were clipped. Two-stage operation was performed in the other 7 patients: 7 aneurysms were clipped in the first surgery and 7 in the second one. One patient received aneurysm clipping only in one side of the brain. CTA was performed again on 11 patients, noting that residual aneurysm neck of the 2 aneurysms existed in 23 clipped aneurysms, that the other aneurysms disappeared, and that the parent arteries were clear. GOS indicated that good surgical outcomes were achieved in 12 patients, light disability in 4 and severe disability in 1.Conclusion The surgical outcomes of intracranial mirror-image aneurysm performed microsurgical operation are predominance. Criminal aneurysms should be determined correctly and clipped firstly; and according to the sites and grades of the aneurysms and the patient's condition, good outcomes can be achieved by choosing one-time operation or two-stage operation.     

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.

Clinical characteristics of ruptured distal middle cerebral artery aneurysms: Review of the literature

Middle cerebral artery (MCA) aneurysms usually arise at the primary MCA bifurcation or trifurcation. Distal MCA aneurysms are rarely considered as sources of aneurysmal subarachnoid hemorrhage (SAH). It has been reported that ruptured distal MCA aneurysms are associated with head trauma, neoplastic emboli, arterial dissection, or bacterial infection. We experienced five cases of ruptured distal MCA aneurysms and evaluated their clinical characteristics. Retrospective analysis of aneurysmal SAH at Kobayashi Neurosurgical Neurological Hospital was performed from January, 2004 to December, 2014. Clinical characteristics of ruptured distal MCA aneurysms were analyzed using our database. Among 191 aneurysmal SAH patients, there were five ruptured distal MCA aneurysms. All patients did not have any specific medical problems such as infectious disease, head trauma, or cardiac disorders. The incidence of ruptured distal MCA aneurysm was higher than expected and was equivalent to 9.4% of the total ruptured MCA aneurysms. Strong male predominance (80%) and M2–3 junction aneurysm preponderance (80%) were observed. In addition, there were only two patients (40%) with intracerebral hematoma in our study. We reported five cases of ruptured distal MCA aneurysms. Although ruptured distal MCA aneurysms are thought to be rare as sources of aneurysmal SAH, the incidence of ruptured distal MCA aneurysm was 9.4% of all ruptured MCA aneurysms in our study. Ruptured distal MCA aneurysms should be considered as sources of aneurysmal SAH without intracerebral hematoma.     

儿童颅内动脉瘤的临床特征及治疗

目的 探讨儿童颅内动脉瘤的发病特点、影像学特征及其治疗策略.方法 对宣武医院神经外科及神经介入中心1985年10月至2008年5月共23例14岁以下(含14岁)儿童的24个颅内动脉瘤的发病方式、部位、大小等影像学特点、治疗方式及其结果进行回顾性分析.结果 儿童颅内动脉瘤占所有年龄组颅内动脉瘤的1.3%,男:女=1.56:1;24个动脉瘤中,16个位于前循环,8个位于后循环;14个属于复杂动脉瘤;以蛛网膜下腔出血为表现者11例;14例采用神经介入治疗,4例采用显微手术治疗,5例未行外科治疗,其中2例在随访过程中动脉瘤及载瘤动脉自行闭塞而自愈;1例死亡,1例因术前动脉瘤再破裂导致中度致残,其余21例结果良好.结论 (1)儿童颅内动脉瘤较为罕见,发病率男性高于女性;(2)颈内动脉及大脑中动脉是儿童颅内动脉瘤的好发部位;(3)与成人相比,巨大动脉瘤、夹层动脉瘤及后循环动脉瘤、感染或外伤性动脉瘤比例较高;(4)神经介入及显微手术都是治疗儿童颅内动脉瘤的有效方法,但对于复杂动脉瘤首选神经介入治疗,相当一部分动脉瘤甚至不得不采用载瘤动脉闭塞的方法治疗.     

大脑中动脉M1段动脉瘤手术治疗体会

目的探讨大脑中动脉M1段动脉瘤特点及显微手术夹闭的技巧和预后。方法总结我科20例不同级别大脑中动脉M1段动脉瘤,在不同时期均采用经翼点入路显微镜下行动脉瘤夹闭。结果动脉瘤均行夹闭,手术后死亡2例,病人发生颞叶大面积脑梗死;出院时格拉斯哥预后评分(GOS)优良10例,中度残4例,重度残3例,植物状态1例。结论大脑中动脉M1段动脉瘤预后差,致残率高,容易发生大面积脑梗死,早期手术及灵活的手术技巧以及术后高灌注和预防脑血管痉挛是改善预后的有效手段。     

微小破裂前交通动脉瘤的血管内栓塞治疗

目的 总结应用血管内技术治疗微小破裂前交通动脉瘤的经验和体会。方法 回顾性分析应用血管内栓塞治疗的22例破裂的微小前交通动脉瘤患者的临床资料、栓塞过程以及结果。结果 22例全部成功栓塞,每个动脉瘤应用1～3个弹簧圈,平均2个。18例完全栓塞,3例95％栓塞,1例瘤颈残留。术中未发生动脉瘤破裂出血。10例影像学复查未见动脉瘤复发。结论 选择合适的病例,血管内栓塞可以安全有效地治疗破裂的微小前交通动脉瘤。     

显微外科手术治疗前交通动脉瘤60例报告

目的探讨经翼点入路夹闭60例前交通动脉瘤的显微外科手术技巧。方法回顾性分析手术治疗60例前交通动脉瘤的临床表现、影像学资料及手术。结果术前DSA能清楚显示动脉瘤的大小、形状以及A1优势征的影像学表现。60例患者中出院时按GOS评分分为恢复良好者51例,中残3例,重残4例,死亡2例。结论大脑前动脉A1段发育不全与前交通动脉瘤的发生有较高的相关性;早期(3d内)行手术夹闭前交通动脉瘤能防止因动脉瘤再次破裂引起的直接死亡和病情恶化;熟练掌握显微外科手术技巧以及术中出现动脉瘤破裂时正确的处理方法,对提高手术成功率至关重要;术中清除脑池内积血,采用罂粟碱灌洗脑池,能减轻脑血管痉挛,改善预后。
