Obstetric management for pregnant women with Klippel-Trenaunay syndrome: A UK case report and review of the literature

Klippel-Trenaunay Syndrome (KTS) is a rare congenital vascular disorder characterized by extensive capillary and venous malformations that pose unique challenges during pregnancy. This case report discusses the successful management of a 34-year-old pregnant woman with KTS who had two caesarean sections, resulting in the birth of two healthy babies. Despite the lack of evidence-based guidelines for obstetrical management in KTS, a multidisciplinary team collaborated to devise a high-risk thrombosis management plan, involving the use of compression stocking and low molecular weight heparin prophylaxis. The patient's elevated risk of thrombosis, exacerbated during pregnancy, informed the decision of caesarean sections, aligning with finding that in most KTS pregnancies, this method of delivery based on obstetric indications and arteriovenous malformations is chosen. This case highlights the importance of systematic and patient-centered care, advocating for comprehensive obstetric management guidelines to address the unique challenges posed by KTS during pregnancy. Further research is warranted to enhance our understanding and refine guidelines for individuals with vascular abnormalities linked to KTS.
