title: Bleeding after circumcision in a newborn receiving sildenafil.
abstract: This report describes a case of bleeding as a complication of circumcision in a 2-week-old infant being treated with sildenafil for persistent pulmonary hypertension of the newborn. The vasodilatory effects of sildenafil on the penile vasculature may have contributed to the postoperative bleeding in this patient.
