Revascularization for bilateral renal artery occlusion after umbilical artery catheterization.
The case of a newborn infant who became hypertensive and oliguric because of bilateral renal artery occlusion following umbilical artery catheterization is presented. Eventual treatment was by microsurgical placement of an aortorenal graft, with subsequent marked improvement in the patient's course. A scan and arteriogram at 1 year showed that the revascularized kidney was responsible for the patient's normal blood urea nitrogen and creatinine concentrations, but the renal artery had recanalized and the graft occluded. The role of umbilical artery catheterization in such catastrophes and the possible future role such microsurgical reconstruction could play in neonatal hypertension are discussed.
