摘要
目的探讨MSCTA在腹部异位卵巢肿瘤起源诊断中的价值。方法回顾性分析经病理证实的以腹部肿块为主要表现的卵巢肿瘤患者28例30侧，采用VR血管生长技术（AV）进行供血动脉成像，MIP显示“卵巢血管蒂”（OVP）征，以手术结果为标准，判断肿瘤起源的准确性。结果28例30侧卵巢肿瘤患者中，最大径5．2～19．5cm，平均9．3cm。子宫动脉卵巢支（ROAU）、卵巢动脉（OA）显影率分别为96．7％（29／30）和56．7％（17／30）。29侧ROAU供血，1侧OA供血，16侧OA参与供血。肿瘤定位诊断敏感性为100％（30／30）。OVP发生率76．7％（23／30），定位诊断敏感性为85．2％（23／27）。结论MSCTA通过显示肿瘤由ROAU、OA供血及卵巢静脉（OV）引流，能准确诊断腹腔异位卵巢肿瘤。
Objective To investigate the value of MSCTA in diagnosing the origin of abdominal ectopic ovarian tumor. Methods Twenty-eight patients with 30 ectopic ovarian tumors that mainly manifested as abdominal lumps were evaluated with MSCTA retrospectively. Vascular three-dimensional reconstruction by VR based on add vessel （AV） and MIP was performed for all these patients after MSCT scanning. The origin of these tumors was judged by the feeding artery and ovarian vascular pedicle （OVP） sign. The result was compared with surgical findings. Results The maximum diameter of the 30 ectopic ovarian tumors ranged from 5.2 to 19. 5 cm with an average of 9. 3 cm. Of the 30 ectopic ovarian tumors, the ramus ovaricus arteriae uterinae （ROAU） and ovarian artery （OA） were demonstrated in 96. 7% （29/30） and 56. 7% （17/30） respectively. The feeding artery of the tumor was ROAU （29 cases） or OA （1 case ）, and OA participated in feeding the tumor in 16 cases. The accuracy rate of diagnosis of ectopic ovarian tumors according to the feeding artery was 100% （30/30）. According to OVP the accuracy rate was 85.2% （23/27） with an incidence of 76. 7% （23/30）. Conclusion By showing ROAU and OA as the feeding artery and ovarian vein （OV） as the draining vein, MSCTA can accurately diagnose ectopic ovary tumors in the abdomen.
