开放手术观察腰椎间盘突出症溶核失败45例分析

目的 通过开放手术观察分析椎间盘髓核化学溶解术治疗腰椎间盘突出症失败原因。方法 收集溶核失败的腰椎间盘突出症45例行开放手术治疗。结果 术中见45例硬膜外脂肪完全消失，43例髓核未见溶解，2例髓核溶解呈糊状但未被吸收，21例伴有侧隐窝狭窄，15例突出物与神经根粘连，20例黄韧带增厚，2例椎管骨性狭窄，14例突出物钙化。结论 腰椎间盘突出症病变间隙合并有侧隐窝狭窄、神经根粘连、椎管狭窄、突出物钙化等，不是溶核治疗的适应证。     

颈椎前路钢板椎间融合器系统治疗颈椎间盘突出症

颈椎前路手术在颈椎间盘疾病中已广泛应用，手术方法主要为颈前路减压加椎间植骨融合术。但不管是早期的自体骨融合的颈前路手术，还是后来进一步发展的颈前路钢板以及椎间融合器技术，都存在着诸如融合失败率高、植骨块移位、塌陷、螺钉断裂、钢板松动等并发症，造成手术疗效不佳以致于二次手术。自2002年2月-2004年1月采用颈椎间盘摘除、颈椎前路钢板椎间融合器（PCB）系统内固定、植骨融合术治疗颈椎间盘突出症后均无前述并发症的发生，疗效满意，现报道如下。     

侧后方潜式减压术治疗下胸段椎间盘突出症

自1996年6月-2000年6月,共收治下胸段椎间盘突出症的病人16例,均行侧后方潜式减压髓核摘除术,效果满意,报告如下.     

Gd-DTPA-enhanced MR in thoracic disc herniations

Summary The Gd-DTPA-enhanced magnetic resonance findings in two patients with herniated thoracic intervertebral discs are reported. The first patient was a 56-year-old woman with a small subligamentous T6-7 disc herniation, slightly lateralized to the right. The second patient was a 51-year-old man with a central and right posterolateral disc herniation, including a large calcified fragment, at the T8-9 level. The nonenhanced MR examination revealed the presence of an extradural mass lesion in both patients, impinging upon the dural sac and compressing and displacing the spinal cord posteriorly. The lesion was slightly hypointense on both T1- and T2-weighted spin echo sequences. Following intravenous injection of Gd-DTPA in a dosage of 0.1 mmol/kg body weight, enhancement of the posterior longitudinal ligament was noted and triangular areas of contrast uptake were seen to occur in the epidural space above and below the herniated disc. At surgery, they were found to correspond to dilated and congested epidural veins.     

超声引导胶原酶治疗外侧型腰椎间盘突出症

目的探讨超声引导胶原酶治疗外侧型腰椎间盘突出症的疗效及安全性.方法在相应椎间盘突出的棘突间,旁开1.5～2.5cm处经皮穿刺,采用超声引导定位,穿刺成功后,先进行加压试验,再进行麻醉试验,无腰麻征象后,将胶原酶注入到突出的椎间盘内或周围.结果 231例病人出院时的优良率为92.21%,有效率为99.57%;随访1～5年的优良率为92.65%,有效率为99.58%.近期与远期疗效比较无显著性差异(χ2=0.129,P＞0.05).结论利用超声引导监测、定位,注射胶原酶治疗外侧型腰椎间盘突出症,安全性强、有效率高.     

小切口椎板间开窗治疗腰椎间盘突出症

目的　探讨小切口椎板间开窗髓核摘除术的疗效及适应证。方法　从 1998年 5月～ 2 0 0 1年 9月采用小切口椎板间开窗髓核摘除术治疗腰椎间盘突出症 72例。全部患者都有腰痛和一侧或双侧下肢疼痛及麻木。结果　获得随访 65例 ,随访时间最长 2 6个月 ,最短 6个月 ,平均 13个月 ,按Nakai标准评定治疗优良率为 93 .8%。结论　小切口椎盘间开窗髓核摘除术具有适应证较广、手术时间短、出血少、创伤小、手术优良率高、后期并发症少、不损害脊柱稳定性等优点 ,是治疗腰椎间盘突出症较为有效和可靠方法之一     

腰椎间盘突出症和马尾神经综合征

本文报告３２例腰椎间盘突出症导致的马尾神经综合征。除腰痛及坐骨神经痛外，本组所有病人均存在鞍区麻木和括约肌功能障碍。根据尿便功能障碍发作程度和持续时间，本组有四种不同的临床表现类型，预后差。异较大。脊髓造影具有诊断和鉴别诊断价值，应用Ｏｍｎｉｐａａｕｅ较Ｃｏｎｒａｙ安全。早期诊断和手术治疗，对括约肌功能、肌力和鞍区浅感觉最大程度地恢复甚为重要。     

Ebstein畸形82例心血管造影分析

报道我院1958～1992年期间的 Ebstein 畸形82例。平片表现可归纳为球型、方型和不典型4种心脏形态。介绍该畸形的心血管造影方法,所见征象和相应的病理基础。主要造影征象有:1.心脏膈面双切迹征;2.帆样征:3.房化心室:4.三尖瓣闭锁不全。本文结合文献对本病病理,X 线表现进行了系统的讨论,并着重突出了我们的观点。     

VASCULAR COMPLICATIONS OF ELECTIVE LOWER LUMBAR DISC SURGERY

Lower lumbar disc surgery is an extremely common operation from which vascular complications are reported rarely. However vascular injury can occur with perforation of the anterior longitudinal ligament. External haemorrhage is uncommon and the true cause of the patient's hypotension may be misdiagnosed. If the hypotension is severe or prolonged laparotomy is indicated, to prevent exsanguination and to effect a repair of the vascular injury. Alternatively, if the injury is missed, an arteriovenous fistula may develop; this diagnosis may be delayed for months or years. One case of severe haemorrhage following lower lumbar disc surgery is reported and a further 69 cases of similar arterial injury have been reviewed from the world literature.
