椎管内肿瘤疼痛特点分析

Pain Characteristics of Intraspinal Canal Tumor

目的：通过对椎管内肿瘤疼痛特点的分析，建议将椎管内肿瘤患者出现的腰穿痛、造影痛、牵引痛、卧眠痛称为椎管内肿瘤楔压症。方法：对２４例椎管内肿瘤患者的临床症状进行了分析。结果：腰穿痛占３５３％，造影痛占７０６％，卧眠痛占７５％，牵引痛占１００％。结论：当肿瘤上、下方脑脊液的压力差增大时或椎管长度有变化时，肿瘤会发生移位，犹如木楔卡压一样，加重对神经组织的压迫。

The purpose of this study was to put forward a new concept,Intraspinal canal tumor wedge pressure syndrome.The syndrome consist of lumbarpuncture pain,myelography pain,dragging pain and decubitus pain.These types of pain are common manifestations of this syndrome.We suggest that the concept of intraspinal canal tumor wedge pressure syndrom is due to tumor shifted by increase of cerebrospinal fluid pressure difference or vertebral canal lengthens.The shift of intraspinal tumor gives rise compression of spinal cord or nerve roods and causes pains or paralysis.Therefore,the concept of intraspinal tumor wedge pressure syndrome may express characteristics of pains of interspinal tumor more accurate and is better guide significance for clinic diagnosis.
