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.     

他汀类药物对肾脏疾病非降脂的保护作用

羟甲基戊二酰辅酶A还原酶抑制剂(3-hydrox-y-3-methylglutaryl Coenzyme A Reductase Inhibi-tors,HRI),又称他汀类药物,是最为经典和有效的降脂药物。近来大量的动物实验和临床试验表明他汀类药物对肾脏的保护作用无法单用降脂来解释,于是许多学者提出了HRI具有非依赖降脂的肾

颅内动脉瘤的血管内栓塞治疗

目的探讨应用电解可脱性弹簧圈(GDC)栓塞治疗颅内动脉瘤的临床效果。方法2002年6月-2004年6月我们采用GDC栓塞颅内动脉瘤126例(其中4例有2个动脉瘤,共130个)。前交通动脉瘤42个,后交通动脉瘤53个,颈内动脉瘤6个,大脑中动脉瘤10个,大脑后动脉瘤8个,大脑前动脉瘤6个,小脑后下动脉瘤2个;基底动脉瘤3个。按Hunt-Hess分级:Ⅰ级38例,Ⅱ级54例,Ⅲ级23例,Ⅳ级11例。必要时辅以篮筐技术、重塑技术、支架技术、双微导管或连环技术、蚕食技术。结果成功栓塞126例动脉瘤,其中103例为100%栓塞,21例为95%,2例为90%。12例在栓塞后6~18个月进行造影随访,所栓塞动脉瘤均未见复发征象。结论GDC栓塞颅内动脉瘤是安全、有效和微创的治疗手段。联合运用多种栓塞技术有助于减少术后并发症,提高治愈率。     

大鼠脑损伤局部谷氨酸的异常释放对乳酸含量变化的影响

目的探讨谷氨酸(Glu)在大鼠脑损伤局部的异常释放以及其对乳酸(Lac)含量变化的影响。方法采用大鼠局部脑损伤动物模型,分为对照组、损伤组、干预组。伤前15min干预组注射Riluzole(一种Glu突触前释放抑制剂),损伤组注射等容量的生理盐水,对照组仅开骨窗不损伤脑。应用微透析技术检测各组伤后不同时间透析液中Glu含量([Glu]d)及Lac含量([Lac]d)变化。结果[Glu]d及[Lac]d在伤后15min、30min和45min干预组明显低于损伤组(P<0.05),而明显高于对照组(P<0.05);在伤后60min,损伤组仍明显高于对照组(P<0.05)。伤后不同时间[Glu]d和[Lac]d变化呈显著正相关(P<0.01)。结论脑损伤后受损脑组织细胞液中Glu水平的升高是Glu神经元末梢大量释放Glu所致,并继而引起了Lac的含量升高。
