The Value Analysis of CT Diagnosis for Lumbar Spinal Stenosis/HU Xue-zhen,LI Zheng-jun,CHEN Hu,et al.//Medical Innovation of China,2014,11(28):123-126
【Abstract】 Objective:To investigate the value of CT diagnosis for lumbar spinal stenosis.Method:CT images of 77 patients with lumbar spinal stenosis were retrospectively analyzed.Result:The analysis in the 77 patients with lumbar spinal stenosis showed that there were 41 cases with lumbar intervertebral disc protrusion(among them 17 cases were L3-4,37 cases were L4-5,32 cases were L5-S1),21 cases with the left side,18 cases on the right side,23 cases were L3-S1 vertebral hyperplasia of small joints and inside,35 cases with the lumbar yellow ligament hypertrophy,both coexist in 19 cases,27 cases were lumbar disc with yellow ligament hypertrophy,15 cases with L3-S1 of lumbar posterior marginal intraosseous cartilaginous node(12 cases were L4) and 7 cases with L3-5 of vertebral compression fracture.L4-5 spondylolisthesis in 14 cases (including 9 cases were L4,9 cases were L5).Conclusion: CT examination can clear the reason,position,degree,scope of lumbar spinal stenosis,provide an important basis for the diagnosis of clinical.

腰椎管狹窄是指腰椎體及附件由于外傷、病變等多種原因引起椎管、神經(jīng)根管、椎間孔狹窄,并使相應(yīng)部位椎管內(nèi)的脊髓、神經(jīng)受壓引起的一系列臨床癥狀[1]。臨床表現(xiàn)為慢性腰痛、蹣跚步態(tài)、下肢感覺(jué)運(yùn)動(dòng)異常及大小便障礙等,以神經(jīng)源性間歇性跛行為主要特點(diǎn)。近年來(lái)報(bào)道較少,為了提高影像科醫(yī)生診斷水平,加深認(rèn)識(shí),本文回顧性分析77例腰椎管狹窄的CT表現(xiàn),現(xiàn)報(bào)告如下。
1 資料與方法
1.1 一般資料 選取本院77例腰椎管狹窄患者,男49例,女28例;年齡22~69歲,平均53歲;病史最長(zhǎng)3.5年,最短1個(gè)月。臨床表現(xiàn)為腰背痛、腰痛伴下肢放射性疼痛、下肢感覺(jué)障礙、間歇性跛行等。
1.2 設(shè)備及檢查方法 采用Brilliance CT(16 Slice)掃描機(jī)進(jìn)行檢查。患者取仰臥位,屈膝位,掃描范圍為L(zhǎng)3~S1椎間隙,層厚2.5 mm,層距2.5 mm,掃描線(xiàn)與椎體或椎間隙平行。掃描參數(shù)為120 kV,200 mA,成像矩陣512 mm×512 mm,軟組織窗和骨窗攝影。
2 結(jié)果
椎間盤(pán)突出41例(其中L3~4 17例,L4~5 37例,L5~S1 32例),伴有左側(cè)突21例,右側(cè)突18例。CT表現(xiàn):椎間盤(pán)中央型后突,偏左或偏右壓迫硬膜囊或同側(cè)神經(jīng)孔致中央椎管并同側(cè)根管狹窄;……
