简介:目的探讨桥小脑角疾病的相位平衡快速梯度回波(Balance-FastFieldEcho,B-FFE)序列MRI影像学特点,评价B-FFE序列对桥小脑角疾病的诊断价值.方法应用B-FFE序列对136例桥小脑角病变者(三叉神经痛131例、半面痉挛5例)进行MRI检查,观察桥小脑角神经、血管、肿瘤显像情况,并与手术中资料进行比较.结果131例三叉神经痛患者中,117例为原发性三叉神经痛,MRI显示有血管压迫者102例,术中证实有血管压迫者95例,行显微血管减压+神经梳理术;14例为继发性三叉神经痛,均为桥小脑角占位性病变,术后病理证实7例为胆脂瘤,2例为听神经瘤,5例为脑膜瘤;5例半面痉挛患者MRI显示有血管压迫,术中证实有血管压迫,并予以血管减压.结论B-FFE序列MRI成像能清楚显示桥小脑角区三叉神经、面神经与血管的关系及是否有占位性病变,对诊断、术前评估和指导治疗有重要意义.
简介:目的:评价Densiron68硅油作为眼内充填物的有效性及安全性。方法:回顾性分析2015-01/2016-01我院眼科因复杂视网膜脱离接受重硅油充填术的患者30例30眼。观察分析术前及术后的最佳矫正视力(BCVA)、眼压、视网膜复位情况及术后并发症等。结果:术前与硅油充填术后BCVA的差异,术前与取硅油术后3moBCVA的差异均有统计学意义(z=-2.198,P=0.028;z=-2.682,P=0.007)。平均术前眼压为16.067±4.025mmHg,硅油充填术后为20.233±8.007mmHg,差异有统计学意义(t=-2.913,P=0.005);而硅油取出术后眼压14.933±3.423mmHg,与术前眼压比较差异无统计学意义(t=2.635,P=0.430)。重硅油取出术后视网膜复位率90%,常见并发症为硅油乳化、并发性白内障。结论:重硅油Densiron68作为眼内充填物治疗复杂性玻璃体视网膜疾病有效及安全,但由于重硅油乳化率较高、术后易并发白内障,因此临床使用时应严格掌握适应证。
简介:目的:测量鼻泪管阻塞性疾病患者鼻泪管管径,分析患眼与正常眼之间、不同性别患眼之间、不同年龄段患眼骨性鼻泪管上、中、下口横向直径的差异,探讨鼻泪管横向直径与鼻泪管阻塞疾病的关系。方法:收集2014-04/2017-01于成都中医药大学附属医院眼科就诊的鼻泪管阻塞性疾病患者152例(患眼179眼,正常眼125眼),其中男25例(患眼28眼,正常眼22眼),女127例(患眼151眼,正常眼103眼),年龄4~87(平均53.44±16.06)岁。所有患者泪道冲洗后灌注30%碘海醇注射液,并立即行泪道计算机断层扫描(computedtomography,CT)检查,二维重建鼻泪管结构图,于斜冠状位上对鼻泪管及其临近组织结构进行观察,测量并分析患眼与正常眼之间、不同性别患眼之间、不同年龄段患眼之间骨性鼻泪管上、中、下口横向直径的差异。结果:患眼与正常眼之间、不同性别患眼之间、不同年龄段患眼之间骨性鼻泪管上、中、下口横向直径值差异均无统计学意义(P>0.05)。患眼和正常眼的鼻泪管上、中、下口横向直径之间比较,差异均有统计学意义(P<0.001),其中中口横向直径最小。结论:骨性鼻泪管横向管径不是形成鼻泪管阻塞的主要原因。
