摘　　要：对经CT/手术证实的7例腰椎间盘脱出症(LDP)和9例椎管狭窄症(LCS)者进行3节段性(L_4,L_5,S_1)SEP研究,并与常规SEP进行比较。14例健康人为对照,结果表明:LCS者节段性SEP示多节段弥散性病损表现,常规SEP为异常。LDP者节段性SEP有助于定位定侧,常规SEP多为正常;这时,如果出现多节段性损伤的表现而常规SEP异常,则非单纯LDP而另有其它病损。Segmental (L4, L5, S1) somatosensory evoked potentials (SegSEP) were studied on 16 patients with lumbar disc heriation (LDH) or lumbar-canal stenosis (LCS), and compared with conventional SEP (SEP_L). 14 healthy volunteers were selected as controls. The main results showed: Multi-segmental abnormal patterns were present on those patients with LCS and SEP_L were all abnormal. In those patients with LDH seg SEP would be helpful to detect the location or laterality of the herniated masses. It is suggested that if seg SEP has shown multi-segmental damages or SEP_L abnormalilies the lesion would not be the simple LDH and in case of complication with another damages should be considered.
