ABSTRACT
Background: The treatment success of catheter-based ovarian vein embolization due to peripheral varicose veins and ovarian vein reflux (OVR) should be investigated in this clinical investagtion. Patients and methods: For this study, 95 female patients were identified over a 5-year period (beginning of 2006 to end of 2011) after catheter-based coil (+/- chemical) embolization of the ovarian vein due to peripheral primary or recurrent varicose veins and proven reflux in the ovarian vein. Treatment success was retrospectively assessed in 2014 by means of a structured telephone interview (n=60), clinical examination (n=56), duplex ultrasound (n=56) and magnetic resonance imaging (n=51) in patients who were willing to participate in the study. Results: After an average of 51.9 months, 95.2% of the 60 included patients were diagnosed with recurrent varicose veins by duplex sonography and 88.1% by clinical examination. In 15.2%, a new intervention was required due to clinical symptoms. The median recurrence-free time was 47.0±5.5 months. A significant improvement by therapy was reported for all subjective symptoms in both pelvis and legs. No significant correlation between radiological findings and complaints or between radiological findings and clinical recurrence was found. Conclusions: The medical history of female patients with peripheral varicose veins should obligatorily include the question of symptoms in the pelvis. An appropriate diagnostic should follow in order to prevent a possible overlook of a pelvic leak point. Only then an individually adapted therapy for symptom relief is possible. Catheter-based ovarian vein embolization is one optional safe procedure that leads to significant improvement of subjective symptoms but does not necessarily prevent recurrent varicose veins.
