Table 4.
The selected morphological and hemodynamic parameters of abdominal and pelvic veins found in second-step assessment with either CT-V or MR-V. The values shown in the table represent the mean (median) ±SD, or the number (percentage) of patients in the group, respectively.
| Parameter or Variable | Recurrence (n = 183) |
No Treatment (n = 352) |
|---|---|---|
| Diameter of LCILV (mm) (1) | 14.1 (14.5) ± 2.2 | 13.4 (13.5) ± 2.7 |
| Diameter of LRV (mm) (2) | 8.1 (9.0) ± 3.8 | 7.8 (9.0) ± 3.6 |
| Diameter of LOV (mm) (3) | 6.7 (6.5) ± 1.9 | 6.6 (6.5) ± 2.1 |
| Diameter of ROV (mm) (3) | 5.8 (5.5) ± 1.7 | 5.9 (5.5) ± 1.9 |
| Diameter of PUV (mm) (4) | 6.7 (7.0) ± 1.3 | 6.6 (6.1) ± 1.4 |
| Reflux in LOV | 125 (68.3%) | 231 (65.6%) |
| Reflux in ROV | 49 (26.8%) | 112 (31.8%) |
Abbreviations used: LCILV—left common iliac vein, LRV—left renal vein, LOV—left ovarian vein, ROV—right ovarian vein, PUV—parauterine veins; (1) measured below crossing with common iliac artery, (2) measured before crossing with superior mesenteric artery, (3) measured in lower (distal) 1/3 of the vein length, (4) the largest diameter observed.
