PURPOSE: To compare chronic pelvic pain outcomes after pelvic venous embolization in patients with pelvic venous disorders with and those without iliac vein compression.
MATERIALS AND METHODS: Patients with pelvic venous disorders who underwent pelvic venous embolization at a single center were retrospectively reviewed. The patients were categorized into iliac vein compression group and non-iliac vein compression group. Chronic pelvic pain control and chronic pelvic pain-free survival were compared between these 2 groups. Risk factors for noncontrol chronic pelvic pain were analyzed via logistic regression. Deep vein thrombosis (DVT) of the lower limb was examined in the iliac vein compression group after the intervention.
RESULTS: Among 102 collected patients, iliac vein compression was identified in 51 patients (50.0%). The iliac vein compression group was younger (35.7 years [SD ± 6.7] vs 43.6 years [SD ± 12.1]; P < .001) and had more lower limb involvement (18 of 51 [35.3%] vs 6 of 51 [11.8%]; P = .009). Chronic pelvic pain control rates (noniliac vein compression group, 40 of 51 [78.4%]; iliac vein compression group, 42 of 51 [82.4%]; P = 1.00) and chronic pelvic pain-free survival rates (P = .941) did not differ significantly between groups. Preinterventional visual analog scale score (adjusted odds ratio [OR], 0.37; 95% CI, 0.21-0.67; P < .001) and lower limb involvement (adjusted OR, 7.49; 95% CI, 2.10-26.68; P = .002) were independent predictors for noncontrol chronic pelvic pain. No DVT of the lower limb was found at the 1-month follow-up in 47 patients with iliac vein compression.
CONCLUSIONS: In patients with pelvic venous disorders and concomitant iliac vein compression but without severe lower limb venous disorder, primary venous embolization alone, without iliac vein stent placement, appears to be safe and effective.
