Description
Summary:	Pelvic venous reflux may be responsible for pelvic venous disorders and/or lower-limb (LL) varicose veins. Ultrasound investigation with Doppler allows a complete study of the entire infra-diaphragmatic venous reservoir. The aim of this study was to guide and standardize the investigation of the pelvic origin of venous reflux in female patients with LL varicose veins. In this case-control study, we applied a comprehensive ultrasound investigation protocol, which involved four steps: (1) venous mapping of the lower limbs; (2) transperineal and vulvar approach; (3) transabdominal approach; and (4) transvaginal approach. Forty-four patients in group 1 (patients with LL varicose veins and pelvic escape points [PEPs]) and 35 patients in group 2 (patients with LL varicose veins without PEPs [control group]) were studied, matched by age. The median age was 43 years in both groups. The calculated body mass index was lower in group 1 (23.4 kg/m2) compared with the control group (25.4 kg/m2), and this difference reached statistical significance (P < .001). The presence of pelvic varicose veins (PVs) by transvaginal ultrasound was 86% in group 1 and 31% in group 2. Perineal PEPs were the most prevalent, being found in 35 patients (79.5%), more frequent on the right (57.14%) than on the left (42.85%) and associated with bilateral PVs 65.7% of the time. In group 1, 23 patients (52%) reported recurrent varicose veins vs eight patients (23%) in the control group (P = .008). Regarding the complaint of dyspareunia, a significant difference was identified between the groups (P = .019), being reported in 10 (23%) patients in group 1 vs one patient (2.9%) in the control group. The median diameters in the transabdominal approach of the left gonadal veins were 6.70 mm for group 1 and 4.60 mm for group 2 (P < .001). In patients with PVs in group 1, the median diameter of PEPs at the trans-perineal window was 4.05 mm. In the transvaginal examination, the mean diameter of the veins in the peri uterine region was 8.71 mm on the left and 7.04 mm on the right. The identification of PEPs by venous mapping demonstrates the pelvic origin of the reflux and its connections with the LL varicose veins. For a more adequate treatment plan, we suggest a complete investigation protocol based on the transabdominal and transvaginal study to rule out venous obstructions, thrombotic or not, and confirm the presence of varicose veins in the pelvic adnexal region.
