We have previously reported that in women with a pelvic venous disorder secondary to pelvic venous insufficiency, 56% will present with an iliac vein stenosis (IVS) and ovarian vein reflux (OVR). The purpose of the present investigation was to determine whether women with combined disease can be treated using iliac vein stenting alone. A retrospective review of prospectively collected data at the Center for Vascular Medicine was performed. We investigated women with pelvic pain or dyspareunia secondary to combined IVS and OVR who had undergone stenting alone. The patient demographics, pre- and 6-month postoperative visual analog scale (VAS) for pain scores, stent type, stent diameter, stent length, and ovarian vein diameters were assessed. All patients had undergone diagnostic venography of their pelvic veins, left ovarian veins, and pelvic reservoirs and intravascular ultrasonography of their iliac veins. From May 2016 to October 2019, 82 patients with a pelvic venous disorder secondary to IVS and OVR were identified. The present data analysis focused on 38 patients with complete pre- and postoperative VAS scores and duplex scan stent patency data at 6 months. The pelvic and dyspareunia VAS scores at the initial and 6-month follow-up visits were as follows: 6.83 ± 3.19 and 4.24 ± 2.65 and 1.72 ± 2.01 and 0.05 ± 2.0, respectively (P ≤ .001). At 6 months, 29 of the 38 women (76%) reported complete resolution of all symptoms, 26 of 28 (93%) reported complete resolution of their dyspareunia, 5 of 38 (13%) reported significant improvement, and 4 of 38 (10%) reported no improvement. The average ovarian vein diameter was 6.7 ± 2.5 mm. The average stent size and length was 18.20 ± 1.6 mm and 92.41 ± 18.5 mm, with 25 placed in the left common iliac, 2 in the right common iliac vein, and 3 bilaterally. Of the 38 patients, 7 required reintervention (18%). An untreated pelvic reservoir was observed in 17 of the 38 patients (44%). One of the two with no response and six of the patients with improvement had OVR and an untreated pelvic reservoir. The remaining 10 patients with a pelvic reservoir had experienced complete resolution of their symptoms with stenting alone. Of the 38 women with pelvic pain secondary to combined IVS and OVR, 76% achieved complete symptom resolution with iliac vein stenting alone. Most of the women with a pelvic reservoir were asymptomatic and reported full symptom resolution after stenting alone. However, these data suggest that in some women
