【摘要】 本文对132例腰椎间盘突出、黄韧带肥厚进行了椎管造影与手术的对照分析。依手术所见,间盘突出分中央型、中央旁型、外侧型和极外侧型,黄韧带肥厚分为后侧部肥厚为主、外侧部肥厚为主、广泛肥厚和局限性嵴状肥厚。对每型的造影表现作了描述。本组两者合并发生率甚高,为80％。提出黄韧带后侧部≥6mm、外侧部≥5mm作为诊断肥厚的指标之一。在45例侧隐窝狭窄中,40例由黄韧带肥厚引起,其中35例神经根袖造影有改变,应予重视。更多还原

【Abstract】 A myelographic—surgical correlative study of disc protrusion and thickening of ligamentum flavum was done in 132 cases. According to surgical findings disc protrusion was devided into central, paracentral, lateral and extrem—lateral types. Thickened ligamentum flavum was classified into postero—lateral portion or lateral portion predominant and diffuse or local crest—like thickening. The myelographic appearances of each type were described. In this series the incidence of the combination of these two diseases was rather high (80%). Among 45 cases of narrowed lateral recesses 40 were caused by thickened ligamentum flavum and 35 showed changes of nerve root sheaths in myelography. We emphasize the importance of these findings. The authors consider that postero—lateral portion ≥6mm and lateral portion ≥5mm may be the criteria for the diagnosis of thickened ligamentum.更多还原
