腰升静脉狭窄致椎管内静脉高压综合征

Venous hypertensive myelopathy caused by narrowing of ascending lumbar vein

目的 探讨腰升静脉狭窄致椎管内静脉高压综合征的临床特点及诊治方法。 方法3例患者经选择性脊髓血管造影及经股静脉插管到腰升静脉造影证实狭窄部位后 ,用MAGIC B1微导管插入静脉狭窄处 ,反复充盈不可脱球囊扩张 ,消除静脉狭窄 ,恢复腰升静脉的正常血液回流 ,解除椎管内静脉高压。 结果 3例患者经上述治疗后随访 1至 2年 ,2例痊愈 ,1例症状减轻。 结论 腰升静脉狭窄是椎管内静脉高压综合征的病因之一 ,治疗应首选腔内血管扩张成形术。

Objective To assess the diagnosis and treatment of venous hypertensive myelopathy(VHM)caused by narrowing of the ascending lumbar vein. Method The data from 3 patients with VHM caused by narrowing of the ascending lumbar vein were analyzed retrospectively. Results Once the narrowed site of the lumbar ascending vein was determined by myelographic or angiographic technique, an undetachable balloon was introduced and advanced to the proximal part of the narrowed segment.Satisfactory results were obtained in these patients Conclusion Narrowing of the ascending lumbar vein is one of the causes for VHM,and endovascular balloon angioplasty is an optimal treatment.
