Pregnancy outcome in patients with Takayasu’s arteritis: cohort study and review of the literature

Abstract

Objective: The objective of this study is to investigate the clinical features of pregnancy in women with Takayasu’s arteritis managed in a tertiary medical center and review the literature in order to establish the course and recommended follow up and treatment for these pregnancies.

Materials and methods: Retrospective analysis of 20 pregnancies in 6 women with Takayasu’s arteritis. Patients were recruited from the high risk pregnancy clinics at Sheba Medical Center, where follow up included strict control of blood pressure and treatment of obstetric and disease-related complications.

Results: Mean maternal age was 29.3 ± 3 years. Thirty-six patients had both supra and infradiaphragmatic arterial disease, of them two had an abdominal aorta involvement and three out of six patients had an isolated supradiaphragmatic disease. Of 20 pregnancies, six pregnancies (30%) resulted in early spontaneous miscarriages, and one pregnancy was terminated at 17 weeks due to fetal anomalies. The remaining 13 pregnancies (65%) resulted in live births. Three out of 13 (23%) neonates were small-for-gestational-age. The most common complication was maternal hypertension affecting 8/13 (61.5%) pregnancies. Preeclampsia occurred in one pregnancy. Four out of 13 (30.7%) pregnancies necessitated preterm induction of labor due to obstetric indications or uncontrolled disease.

Conclusions: Although Takayasu’s arteritis is associated with pregnancy complications, tight preconception disease control, strict follow up, and targeted treatment of high blood pressure can result in positive pregnancy outcome.
