Umbilical vessels pathology

Introduction

SUA — single umbilical artery.

Clinical signs

about 1% of singletons at term, up to 10 % of twins
common association with some malformations e.g. sirenomely, trisomy 18, 13, VACTERL
occult malformations (renal in particular) should be searched for in an otherwise healthy infant with SUA
association between low birth weight and SUA is controversial
