The values shown in the table represent mean ±SD, as well asthe number (percent) of cases within the respective group. Abbreviations: SD: standard deviation, LOV: left ovarian vein, ROV: right ovarian vein, PUV: parauterine vein, LRV: left renal vein, RRV: right renal vein, ILV: iliac veins, and IVC: inferior vena cava. The values marked with asterisks (*) were statistically significantly different compared to corresponding values in the P0AM group.
