To determine the usefulness of CT-guided percutaneous drainage for the causative microorganism detection in patients with spondylodiscitis.
Data of patients who underwent CT-guided percutaneous drainage for spondylodiscitis from January 2014 to April 2022 were extracted from the radiological database of our hospital and investigated. The administration rate of antibiotics prior to blood culture and CT-guided percutaneous drainage (CTPD) were analyzed. The detection rate of microorganisms via blood culture and CT-guided percutaneous drainage were compared using the Mann-Whitney's U test with the SPSS software.
In this study, a total of 30 (20 male and 10 female) patients were analyzed. A total of 13 patients (43%) were administered antibiotics prior to blood culture. Of them, microorganisms were detected via blood culture in only one patient (7%). A total of 25 patients (83%) were administered antibiotics prior to CTPD. Of them, the causative microorganisms in 19 patients (76%) were detected. Overall, the causative microorganism could be detected in 24 out of 26 patients (92%) via CT-guided percutaneous drainage. There was a statistical significance in the detection rate of microorganisms between blood culture and CTPD (P = 0.004) in favor of CTPD.
CT-guided percutaneous drainage showed a high positive rate of microorganism detection in patients with spondylodiscitis regardless of antibiotic administration prior to the procedure. CT-guided percutaneous drainage can be a solution for the detection of the causative microorganism in spondylodiscitis patients who received antibiotics before obtaining any culture.
确定CT引导下经皮引流在脊椎椎间盘炎患者致病微生物检测中的效用。
从我院放射学数据库中提取2014年1月至2022年4月因脊椎椎间盘炎接受CT引导下经皮引流的患者数据并进行研究。分析血培养及CT引导下经皮引流（CTPD）前抗生素的使用比例。使用SPSS软件，通过Mann-Whitney U检验比较血培养和CT引导下经皮引流的微生物检出率。
本研究共分析了30例患者（20例男性，10例女性）。共有13例患者（43%）在血培养前使用了抗生素。其中，仅1例患者（7%）通过血培养检测到微生物。共有25例患者（83%）在CTPD前使用了抗生素。其中，19例患者（76%）检测到致病微生物。总体而言，26例患者中有24例（92%）通过CT引导下经皮引流检测到致病微生物。血培养和CTPD的微生物检出率存在统计学差异（P = 0.004），CTPD更具优势。
无论术前是否使用抗生素，CT引导下经皮引流在脊椎椎间盘炎患者中均显示出较高的微生物检出阳性率。对于在进行任何培养之前已接受抗生素治疗的脊椎椎间盘炎患者，CT引导下经皮引流可为致病微生物的检测提供一种解决方案。
