title: Case studies of patients successfully and unsuccessfully managed pre- and post-Fontan procedure.
abstract: As a result of advances and modifications in surgical procedures and the development of drugs for pulmonary arterial hypertension, many patients who have undergone Fontan procedures are able to enjoy good quality of life, without pulmonary arterial hypertension and severe complications. In Shizuoka Children's Hospital, drugs for pulmonary arterial hypertension have long been given to Fontan candidates and patients with established Fontan circulation to maintain sufficient pulmonary blood flow and suppress pulmonary arterial hypertension. We present three typical cases that were treated with anti-pulmonary hypertensive drugs before or after Fontan procedure. The first case had asplenia syndrome, and a single ventricle with major aortopulmonary collateral arteries. Anti-pulmonary hypertensive therapy permitted a Fontan procedure and maintained a good long-term quality of life. The second case was a Down syndrome patient who had progressive cyanosis after a Fontan operation. Anti-pulmonary hypertensive therapy improved cyanosis. The third case suffered from protein-losing enteropathy, for which all procedures and medical therapies were ineffective. Fontan candidates and patients with Fontan circulation have varied anatomical backgrounds and pulmonary properties. We must identify the conditions that lead to successful Fontan procedure and Fontan circulation correction, as well as conditions that result in failed Fontan procedure and poorly-controlled Fontan circulation.
