Abstract
OBJECTIVE
To identify the effects of patient risk factors and pelvic venous reflux (PVR) patterns on treatment outcomes of Pelvic Vein Embolisation (PVE) for Pelvic Venous Disorder (PeVD).
METHODS
We performed a retrospective cohort review assessing population, intervention, comparison, and outcomes (PICO) for women undergoing PVE for PVR January 2017-January 2021. We identified 190 patients who had completed both questionnaires and who had given consent for their information to be used for research (Median age 46, IQR 40-52). The distribution of pathological pelvic venous reflux found on transvaginal duplex ultrasound (TVDUS) was analysed for all patients. Pre- and post-procedure symptom burden scores were studied using a standardised questionnaire protocol. We used inferential univariate non-parametric statistics to describe our data.
RESULTS
190 cases were reviewed; 62.6% (119/190) premenopausal, 11.1% (21/190) perimenopausal, 25.3% (48/190) postmenopausal and menopausal status not documented 1% (2/190). 10.1% (19/188) were nulliparous (average age 34 years; range 20-55 years). There was a statistically significant improvement in all symptoms and in the appearance of varicosities on TVDUS post-PVE (P < 0.05) of the ovarian vein plexus, uterus plexus, arcuate veins, vaginal wall, peri-urethral, peri-anal, haemorrhoids, labial and proximal thigh. The locations of veins requiring embolisation having demonstrated reflux were analysed; 82.8% (154/186) underwent embolisation of at least one internal iliac vein tributary and ovarian vein embolisation. Age, parity, menopausal status and previous laparoscopy did not affect symptom improvement (P > 0.05). No significant complications such as coil migration were observed.
CONCLUSIONS
PVE is an effective treatment for pelvic pain due to PeVD and its diagnosis should not be limited to multiparous women of childbearing age, as a significant proportion of patients who benefited from PVE were either nulliparous and/or postmenopausal.
