摘　　要：目的评估多层螺旋CT(MSCT)用于盆腔静脉淤血综合征(PVCS)患者病因学分析的可行性。方法回顾性分析明确诊断为PVCS的134例患者的临床和影像资料,分析PVCS的解剖学病因及比较2组患者有无血管变异的临床和影像学差异。结果134例患者中共发现血管变异69例,包括左肾静脉(LRV)远端发育不全37例、胡桃夹征22例、卵巢静脉(OV)变异6例、LRV变异2例、门静脉高压2例、盆腔动静脉瘘2例、左髂静脉压迫综合征、左肾旋转不良和左肾动静脉瘘各1例。余65例患者未发现血管变异。2组患者的左侧卵巢静脉(LOV)直径和反流程度差异有统计学意义(t=2.544,P=0.012;χ^(2)=21.797,P<0.001),存在血管变异者LOV直径更粗,反流程度更高;2组患者的年龄、症状、孕产次数和体质量指数(BMI)值等无统计学差异(P>0.05)。结论MSCT可以为PVCS的病因学分析提供重要参考价值,明确诊断有助于进一步的精准治疗。Objective To evaluate the feasibility of multi spiral computed tomography(MSCT)for etiological analysis of patients with pelvic venous congestion syndrome(PVCS).Methods The clinical and imaging data of 134 patients diagnosed with PVCS were analyzed retrospectively.The anatomical etiology of PVCS was analyzed,and the clinical and imaging differences between the two groups with and without vascular variation were compared.Results Among the 134 patients,69 had vascular variation,which included 37 distal hypoplasia of left renal vein(LRV),22 nutcracker phenomenon,6 ovarian vein(OV)variation,2 LRV variation,2 portal hypertension,2 pelvic arteriovenous fistula,1 left iliac vein compression syndrome,1 left renal malrotation and 1 left renal arteriovenous fistula.The remaining 65 cases showed no vascular variation.There were statistically significant differences in the left ovarian vein(LOV)diameter and reflux degree between the two groups(t=2.544,P=0.012;χ^(2)=21.797,P<0.001).Patients with vascular variation had wider diameter of LOV and higher degree of reflux.There were no statistically significant differences between the two groups regarding age,symptom,times of pregnancy and delivery and body mass index(BMI)values(P>0.05).Conclusion MSCT can provide important reference value for etiological analysis of PVCS,which is helpful for precise treatment.
