PURPOSE: Short-term effects of round ligament varicosity (RLV) in pregnancy have been investigated in small-scale studies. The long-term effects are unknown. This study aims to evaluate the risk of groin hernia manifestation after RLV in pregnancy, to delineate possible risk factors and to analyze the natural course of pregnancy and post-partum period with regard to RLV.
METHODS: In a prospective analysis 28 pregnant women with RLV presented to the hernia clinic over 9 years. After clinical and ultrasound examination during pregnancy and publication of early results in 2013 a second structured follow-up was conducted. Demographic data, hernia-specific risk factors, comorbidities, pregnancy and birth-related data as well as post-partum period were documented without loss of follow-up. In these women, all pregnancies that occurred, including the ones without RLV, were analyzed.
RESULTS: Median follow-up was 68 months (11.4-104.9). Only one groin hernia was found. No risk factors could be identified. After uncomplicated childbirth complaints subsided spontaneously in all but one patient within 4 weeks. Recurrence rates in subsequent pregnancies are up to 89%.
CONCLUSION: Temporary RLV-induced dilation of the deep inguinal ring in pregnancy is not a common precursor for the development of inguinal hernias later in life. All findings support the theory that the hindrance of venous blood flow caused by the gravid uterus is an important contributing factor for RLV in pregnancy, which is self-limited but has a high risk of recurrence and is not an indication for surgery before or after delivery or for cesarean section.
