血栓闭塞性脉管炎的腔内治疗

Objective To investigate the value of endovascular surgery for the treatment of thromboangitis obliterans (TAO). Methods Sixteen patients (18 limbs) with thromboangitis obliterans were treated by percutaneous transluminal plasty (PTA). Results Angiographic success on the limb basis was achieved in 15 of 18 treated limbs and the initial technical success rate was 83.34%. Doppler anklebrachial index (ABI) increased from 0.33±0.16 to 0.79±0.23 one week after PTA. The follow-up time was 2～24 months, the average time was 10.84 months. The 3-month, 12-month accumulated primary patency rate were 81.33% and 60. 23% respectively. Conclusion PTA is effective primary invasive treatment for thromboangitis obliterans yielding acceptable primary clinical success with a low complication rate and resulting in moderate long-term clinical patency and a high limb salvage rate.

AgNOR在膀胱移行细胞肿瘤分级中的应用

在40例膀胱移行上皮乳头状瘤及移行细胞癌Ⅰ、Ⅱ、Ⅲ级病变的石蜡组织切片上,采用AgNOR染色技术,进行了核仁组成区嗜银蛋白的研究。结果表明,除移行上皮乳头状瘤与移行细胞癌Ⅰ级间P>0.05,AgNOR计数无显著差异外,在Ⅰ、Ⅱ、Ⅲ三级移行细胞癌中AgNOR计数均有显著意义(P<0.01)。当对移行细胞癌进行分级遇到困难时,可能采用AgNOR技术对肿瘤分级的诊断具有辅助作用。     

经单鼻孔蝶窦入路显微手术治疗垂体腺瘤

目的：探讨经单鼻孔蝶窦入路显微手术治疗垂体腺瘤的手术适应证、手术技巧和临床治疗效果。方法：对20例采用该入路手术治疗的垂体腺瘤病人临床资料进行回顾总结。结果：全切15例,大部分切除3例,部分切除2例。14例视力、视野较术前有不同程度改善,3例月经恢复。结论：该手术入路是创伤较小,安全有效的治疗垂体腺瘤的手术方法。     

神经系统影像诊断学的新进展

近年来,随着计算机技术的快速发展,神经系统成像上涌现出许多新的技术,它们不仅能提供神经系统的形态学信息,亦可反映某些功能信息,从而提高了对疾病的认识和诊断水平。本文就当前神经系统影像诊断学上最受国际瞩目的一些新技术及进展,如脑血管成像、功能性磁共振成像、磁共振波谱技术等做了较为详实的介绍,并阐述了其应用现状及发展前景。     

门-体脑病:MR图象上基底节高信号病变

作者在16例肝硬化病人作了头部MRI和经动脉门静脉造影,以评价基底节病变和门-体侧枝血管的关系。男12例,女4例,年龄50～76岁。MR检查时病人均无神经精神症状,病例中不包括有神经精神症状,Wilson氏病和酒精中毒者。16例中见有4例门-体脑病,症状与失代偿性肝改变和肝性脑病不同。检查时神经精神活动正常,但后来有脑病发作,特征为情感及人格改变、精神紊乱、嗜睡、扑翼样震颤及高血氨,治疗3天～2周恢复。作者研究了MR T_1加权象基底节异常高信号和
