颅内出血性椎动脉夹层的治疗 总被引:2,自引:0,他引:2
目的探讨颅内出血性椎动脉夹层的治疗方法。方法回顾分析了2000-2005年40例出血性颅内段椎动脉夹层的治疗。其中支架辅助的弹簧圈栓塞33例,夹层段动脉闭塞6例,夹层近端主干动脉闭塞1例。结果手术无死亡病例。术后随访1-46个月,平均16.3个月。发现夹层动脉通畅,无夹层再出血,无新发后循环梗死。1例支架辅助弹簧圈栓塞患者夹层复发,行补充填塞弹簧圈。结论血管内夹层近端闭塞以及夹层段动脉闭塞是治疗颅内出血性椎动脉夹层的经典术式。支架辅助的弹簧圈栓塞治疗保留了载瘤动脉,避免了术后对侧椎动脉血流负荷量的增加;减少了后循环缺血的危险,扩大了血管内治疗出血性椎动脉夹层的手术适应证。本组结果显示支架辅助弹簧圈栓塞术并未增加夹层再通以及穿支动脉闭塞。本组经验初步表明支架辅助的弹簧圈栓塞是治疗出血性颅内椎动脉夹层的合理选择之一。 相似文献

本文用X线摄片的方法,对西宁地区胎龄为17—36周的60例胎儿脊柱的骨化及生长动态进行了研究。结果:1、提供了高原地区人胎儿脊柱长轴生长发育的资料。脊柱各段以胸段为最长,其次为腰、颈、骶段。2、计算出胎龄与脊柱各段长度间的回归方程,据此可以胎龄推算脊柱的长度,反之亦可以脊柱的长度估计胎龄。3、报道了颈、骶、尾段亿发骨化点出现顺序的规律。 相似文献

Summary Histological, ultrastructural and morphometrical observations on Clarke's column were carried out in 18 patients with sporadic amyotrophic lateral sclerosis (ALS) and 15 age-matched control subjects. Of the 18 ALS patients 6 had been on a respirator before death. Bunina bodies were found in the neuronal cytoplasm in 7 of the 12 non-respirator-supported ALS patients and in 3 of the 6 respirator-supported patients. The number of spheroids was significantly higher in the non-respirator-supported patients (P<0.01) than in the control subjects; however, the number in the respirator-supported patients was about equal to that in the controls. The number of neurons in Clarke's column in the non-respirator-supported ALS patients was not reduced, but in the respirator-supported patients they tended to disappear with time after respiratory support. These findings suggest that Clarke's column neurons are also involved primarily in the disease process in sporadic ALS. However, they may begin to disappear only after the patients require respiratory support.Supported in part by a research grant for CNS degenerative diseases from the Ministry of Health and Welfare, Japan 相似文献

Ten patients suffering from intramedullary pilocytic astrocytomas (WHO-classification: astrocytoma grade I) were investigated catamnesticly. Combined surgery and radiotherapy was performed. Seven patients received neutron irradiation postoperatively. In four cases the neurological symptoms were improved after follow-up periods ranging from 33 to 89 months. The three other patients died after 6 to 21 months. The autopsy findings of a 14 year old child are presented. Our results are compared with reports in the literature. In addition, long-term problems of the spinal column are discussed. It seems that the combined surgical and neutron therapy improves the prognosis of pencil gliomas. 相似文献

Summary A new gas-liquid chromatographic (GLC) determination of cholesterol sulfate (CS) and dehydroepiandrosterone sulfate (DHEAS) for a biochemical diagnosis of recessive X-linked ichthyosis (RXLI) is described. Although the GLC method for determination of CS is known to be more sensitive than the thin layer chromatographic (TLC) method, the former method has not been widely employed because of its complicated pre-purification steps. The present method allows us to measure the serum levels of CS and DHEAS without tedious purification steps such as multiple conventional column chromatography and preparative thin layer chromatography. Sulfated steroids are rapidly purified with a commercially available mini disposable cyclohexylsilane-bonded phase (CH) column, CH BOND ELUT, and the purified steroids after desulfation are converted to water-resistant tert-butyldimethylsilyl ether derivatives for the GLC analysis on dual 2 m glass columns packed with 2% XE-60 on Chromosorb W.By the present method, serum CS concentrations in RXLI patients were shown to be about 10 times higher than those in patients with ichthyosis vulgaris, carriers of RXLI, and healthy subjects. This method is more suitable not only for a biochemical diagnosis of RXLI but also for studies on the metabolism of sulfated steroids than the previous time-consuming GLC methods. 相似文献

In addition to estrogen widely used all over the world for the prevention of postmenopausal osteoporosis, calcitonin and vitamin
D derivatives are commonly employed to treat established osteoporosis at higher age in Japan. In order to critically assess
the usefulness of vitamin D derivatives and calcitonin alone or in combination on the advancement of vertebral deformity at
higher age, 32 osteoporotic patients with vertebral deformity with the mean age of 79 were randomly divided into 4 groups
with indistinguishable age and severity of the vertebral deformity. Group 1 served as the control without specific medications
for osteoporosis. Group 2 was treated with 10 units elcatonin (eel calcitonin derivative) injected intramuscularly twice a
week. Group 3 was given 0.75 to 1.5μg/day 1α (OH) vitamin D3 orally. Group 4 was given a combination of treatments used in Groups 2 and 3.
In the lateral X-ray film of the spine taken prior to the test and every 6 months thereafter, the shape of the vertebral body
T8 through L4 was monitored by measuring the anterior, central and posterior heights. Decrease of the vertebral height ratio; anterior
or middle height/posterior or adjacent intact posterior height, by more than 20% of the original value or from above to below
0.80 both appeared to be inhibited during administration of 1α (OH) vitamin D3. Such effect seems to be augmented by simultaneous administration of elcatonin. Actual decrease of vertebral height ratio
values and the per cent fall from the original value significantly less in Groups 3 and 4 than in Group 1. Development of
vertebral deformity assessed by the changes of the vertebral height thus appears to decrease during treatment with 1α (OH) vitamin D3 especially together with calcitonin in established osteoporosis. 相似文献

椎动脉型颈椎病血浆内皮素变化 总被引:45,自引:0,他引:45
目的:通过观察内皮素(endothelinET)在椎动脉型颈椎病患者血浆中的变化,探讨其在该病中的病理学作用和意义。方法:用放射免疫方法分别对30例正常人和30例患者、20例椎动脉减压术患者术前和术后的血浆内皮素测定。结果:椎动脉型颈椎病患者血浆ET含量(119.46±58.65ng/l)明显高于正常对照组(38.34±14.33ng/l);20例手术患者术后ET含量(50.84±21.67ng/l)明显低于术前ET含量(139.34±52.56ng/l),经统计学t检验有显著性意义(P值<0.001)。结论:ET可能是椎动脉型颈椎病发病中的重要体液因素之一,探讨ET抗体和特异ET受体阻滞剂将为治疗该病提供新的启示。 相似文献
