Abstract:
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 hyper-tension,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;χ2=21.797,P<0.001).Patients with vascular varia-tion 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.
