Uterine leiomyoma (fibroids), which are often found in child-bearing age, can lead to complications in pregnancy and hence are considered to be of high risk.

Aims and Objectives To observe the effects of fibroids in pregnancy and look at associated maternal and fetal complications.

Methods A population-based retrospective study was conducted in a central London tertiary hospital. Women were identified from first Trimester Ultrasound scans (done between January and December 2011) database using search word ‘Fibroids’ and their pregnancy outcome noted from the local obstetric electronic system.

Results 201 women were identified, of which 42 did not deliver at our hospital, making final sample size 159. We looked into the incidence of preterm birth (PTB), low birth weight (LBW) babies (<2500 gm), operative delivery (abdominal and vaginal) and the occurrence of Postpartum Haemorrhage (PPH).

Among the 159 women, 13 (8.17%) delivered preterm (<37 weeks), while 4 (2.53%) had miscarriages. The occurrence of LBW was 16 (10.06%). Spontaneous vaginal delivery (SVD) occurred in 53 (33.33%) cases, instrumental vaginal delivery (forceps and ventouse) in 32 (20.12%) cases, and Caesarean section (CS) was performed in 70 cases (44.02%). The primary indications for CS included failure to progress in labour 11 (15.71%), fetal distress 15 (21.43%), previous Caesarean section 15 (21.43%), and malpresentation 12 (17.14%). Minor and major PPH were observed in 41 (25.78%) and 6 (3.77%) cases, respectively.

Conclusion We found pregnancies with fibroids to be statistically correlated with increased Caesarean section and PPH. These results highlight the necessity for good antenatal, intrapartum, and postpartum care for optimum outcome.
