Management of arterial hypertension occurring early after living donor liver transplantation in children: report of three cases and review of the literature.

Three pediatric patients with hypertension occurring early after liver transplantation are reviewed. The patients were all female, and underwent living donor liver transplantation at the age of 9 years, 1 month, and 7 months. The etiology of liver disease was cirrhosis due to biliary atresia in two patients and fulminant hepatitis in one patient. Antihypertensive therapy with calcium channel blocker alone was not effective. Blood pressure was eventually controlled after the administration of a beta-adrenergic blocker in addition to the calcium channel blocker to all patients. No end-organ damage was observed, except that two patients developed temporary left ventricular hypertrophy.
