盆腔淤血综合征右侧卵巢静脉动脉期显影及其意义

Arterial Phase Display and Significance of Right Ovarian Vein in the Diagnosis of Pelvic Congestion Syndrome

目的探讨盆腔淤血综合征(PCS)患者行多层螺旋CT血管造影(MSCTA)时右侧卵巢静脉(ROV)动脉期显影的意义。资料与方法搜集经临床及影像学检查证实且行MSCTA检查的43例PCS患者,采用容积再现血管生长、最大密度投影进行血管重建,分析ROV动脉期显影与汇入部位、左侧卵巢静脉(LOV)、盆腔引流静脉动脉期显影的关系。结果 ROV动脉期显影43例中,21例(48.8%)ROV作为PCS引流静脉,17例(81.0%)ROV汇入下腔静脉。19例(44.2%)ROV参与PCS的形成,ROV均开口于右肾静脉主干。3例(7.0%)为右肾静脉源性PCS,2例ROV开口于右肾静脉主干,1例开口于右肾静脉分支。结论根据双侧卵巢静脉及盆腔静脉显影情况,可以判断ROV作为PCS的引流静脉、参与或形成PCS。

Purpose To investigate the significance of arterial phase display of right ovarian vein （ROV） for patients with pelvic congestion syndrome （PCS） through multi- slice CT angiography （MSCTA） Materials and Methods Forty-three patients with PCS confirmed clinically who underwent MSCTA were involved in the study. Revascularization was realized via add vessel volume rendering technique and maximum intensity projection （MIP） and the relationships among ROV early development, location of converging vascular, development of LOV and pelvic draining veins were analyzed. Results Out of 43 cases of ROV early development during arterial phase, 21 cases （48.8%） took ROV as draining vein of PCS, among which 17 cases （81.0%） converged into the inferior cava vena. In 19 cases （44.2%）, ROV took part in the formation of PCS, all originating from the main right renal vein. Three cases （7.0%） were renal vein-derived PCS, among which two ROV originated from the main right renal vein and one from the branch of the right renal vein. Conolusion According to the imaging features of bilateral ovarian veins and pelvic veins, ROV, as draining veins, is associated with the formation of PCS.
