Diskography is commonly performed to investigate pain of suspected diskogenic origin. Although uncommon, diskitis is a feared complication of this procedure. We reviewed the incidence of diskitis and other infectious complications following diskography in a large busy outpatient practice and discuss technical aspects that may contribute to infection prevention.
We reviewed the electronic records of all diskograms obtained at our institution during a 12.25-year period, looking for all cases of procedure-related infection. All diskograms had been obtained by skilled and experienced procedural radiologists in dedicated spine-injection suites with specialized technical staff.
There were 12,634 examinations performed on 10,663 patients for a total of 37,135 disk levels. Of the disk levels, 5981 were cervical; 3083, thoracic; and 28,071, lumbar. Two cases of confirmed lumbar diskitis and no cases of either cervical or thoracic diskitis were seen in our series. No other infectious complications were found. The incidence of diskitis was 0.016% per examination and 0.0054% per disk level.
In skilled and experienced hands using proper technique, diskography is a safe outpatient procedure with an extremely low incidence of diskitis and other procedure-related infections.
椎间盘造影术常用于调查疑似椎间盘源性疼痛。虽然不常见，但椎间盘炎是该手术令人担忧的并发症。我们回顾了在一家繁忙的大型门诊机构中，椎间盘造影术后椎间盘炎及其他感染性并发症的发生率，并讨论可能有助于预防感染的技术环节。
我们回顾了在12.25年期间在本机构进行的所有椎间盘造影的电子记录，以查找所有与手术相关的感染病例。所有椎间盘造影均由经验丰富的专业放射科医生在配备专业技术人员的专用脊柱注射室进行。
对10,663例患者进行了12,634次检查，共涉及37,135个椎间盘节段。其中，颈椎间盘节段5981个；胸椎间盘节段3083个；腰椎间盘节段28,071个。在我们的系列研究中，发现2例确诊的腰椎椎间盘炎，未发现颈椎或胸椎间盘炎病例。未发现其他感染性并发症。椎间盘炎的发生率为每次检查0.016%，每个椎间盘节段0.0054%。
在技术熟练、经验丰富的医生手中，采用适当的技术，椎间盘造影术是一种安全的门诊手术，椎间盘炎及其他与手术相关感染的发生率极低。
