Abstract: There are two approaches to treating pelvic congestion syndrome (PCS): (i) the keep-it-simple (KIS) approach, which involves embolising only the refluxing vein(s), typically the left ovarian vein (LOV) unless the right ovarian vein (ROV) or left/right internal iliac vein (IIV) tributaries are also refluxing; and (ii) the extensive (EXT) approach, which empirically embolises almost all of the LOV, ROV, and left and right IIV tributaries. The aim of this study is to determine whether the KIS approach can effectively treat PCS while minimising the number of treated veins and coils used, without the need for injecting sclerosing agents into pelvic veins or the use of occlusion balloons. This is a single-institution retrospective cohort study. Our records identified 154 women who underwent venograms for possible PCS, with the intent to proceed with embolisation. Refluxing veins were treated using the KIS approach, deploying minimal number of coils, 'sandwiching' sclerosing foam. Short-term follow-up was conducted at 6 weeks; long-term follow-ups (between 12 and 60 months) were conducted via an electronic survey consisting of 19 questions assessing pelvic pain/pressure, leg and back pain, fatigue, and bladder and menstrual symptoms. Fifteen women had negative venogram; 139 women had one or more refluxing veins on venogram. Most women (73%) required unilateral ovarian vein (OV) embolisation, 14% required bilateral OV embolisation, and 12% underwent pelvic vein embolisation. Most cases required only four pushable coils. Clinical success was 89% at 6 weeks and 84% at 1-5 years. A visual analogue scale reduction of 5.2 points (from 7.8 to 2.7) was achieved. There were no instances of coil dislodgement or other complications. The keep-it-simple approach, embolising only the refluxing ovarian and/or iliac veins, can achieve a successful clinical outcome for pelvic congestion syndrome. The extensive approach of empirically embolising all ovarian veins and internal iliac veins may not be necessary. This carries implications for potential savings in procedure time, cost and radiation dose.
