摘要
目的探讨利用盆、腹腔多排螺旋CT(MDCT)研究卵巢静脉及卵巢血管蒂征(OVPS)对于女性盆腔肿瘤来源的诊断价值。方法选择2006年10月至2011年4月在本院临床诊断为妇科肿瘤的患者297例为研究对象。采取回顾性分析法,对其按照MDCT观察双侧OVPS结果,将其分为病例组(n=208,卵巢来源肿瘤累及侧卵巢)和对照组(n=386,非卵巢来源肿瘤累及侧卵巢+健侧卵巢)。采用MDCT测量双侧卵巢静脉的最大短径,以病理学检查结果为诊断金标准,对OVPS进行诊断性试验。结果①OVPS判断盆腔肿瘤为卵巢来源的敏感度、特异度、阳性预测值及阴性预测值分别为97.60%(203/208),92.75%(358/386),87.88%(203/231)和98.62%(358/363),准确率为94.44%(561/594),与术后卵巢组织病理学检查结果比较,差异有统计学意义(P<0.005);②单侧卵巢肿瘤患者的健侧与患侧卵巢静脉直径比较,差异有统计学意义(P<0.05)。结论 OVPS对于判断女性盆腔肿块是否来源于卵巢,或来源于哪一侧卵巢的定位价值高,而卵巢静脉直径判断盆腔肿瘤的定位诊断价值较低。
Objective To explore the use of the ovarian vascular pedicle sign（OVPS） as well as the diameters of ovarian veins to differentiate the fmales with a large pelvic mass on multidetector CT （MDCT）. Methods In our study, from October 2006 to April 2011, we elected 297 patients, who had clinical diagnosis of gynecological tumor in our hospital. We observed retrospectively whether there was OVPS or not in each case with MDCT,and divided into patient group （n= 208, the source of ovarian tumor involving the side） and the control group （n = 386, non-ovarian source of ovarian tumors involving the side ＋ the uninjured side）. We measured the diameter of bilateral ovarian vein with MDCT. The pathological results was served as the golden standard, and diagnostic test was performed for OVPS. Results①Compared with the pathological results, results show that the presence of OVPS on MDCT was statistically significant （P〈0. 005） to differentiate the source of the ovarian tumor, and the sensitivity, specificity, positive predictive value and negative predictive value were 97. 60 % （203/208）, 92. 75 % （ 358/386 ）, 87. 88 % （ 203/231 ）, 98.62 % （358/363）, and diagnostic accuracy rate was 94.44 % （561/594）. ② there was significant difference in the diameter of the ovarian veins between the mass side and contralateral side in the patients with an ovarian mass. Conclusion OVPS plays an important role in locating the source of ovarian tumor in females with a large pelvic mass. and the value of the diameter of the ovarian veins in differentiating ovarian origin or not was low.
