Objective To investigate the impact of three kinds of palliative operation on the body and growth of pulmonary artery in patients with congenital heart diseases of diminutive pulmonary blood. Methods Clinical data was reviewed in 28 cases of congenital heart diseases with diminutive pulmonary blood who had been performed cavopulmonary connection （n = 9）, systemic-pulmonary shunt （n = 8 ）, and palliative reconstruction of right ventricular outflow tract （n=11）. The period between re-hospitalized and the first was 5-54 months （19.07±10. 06 months ）. Hematocrit （HCT）, hemoglobin （Hb）, percutaneous oxygen saturation （SpO2）, body surface area （BSA）, and pulmonary artery index （PAI） etc. were observed both before palliation and before the second operation. Results After the second hospitalization, there were 7 cases of death from hemorrhage, failure of circulation and extracorporeal circulation accident etc. The time of respirator, intensive care unit and total amount of dopamine in patients of palliative reconstruction of right ventricular outflow tract were longer and more than those in patients of cavopulmonary connection （P〈0. 05）. HCT, Hb before the second operation were decreased than thoes before palliative operations in all patients, SpO2, BSA and PAI increased significantly （P 〈 0. 01 ）. Before the second operation, BSA of patients with cavopulmonary connection, BSA and PAI of patients with systemic-pulmonary shunt, SpO2, BSA and PAI of patients with palliative reconstruction of right ventricular outflow tract were increased than those before palliative operations（P〈0. 01）. HCT of palliative reconstruction of right ventricular outflow tract was decreased（P〈0. 05）. Conclusion This results suggests that pulmonary blood of patients with congenital heart diseases of diminutive pulmonary blood can be increased, development of pulmonary arteries can be improved efficiently by systemic-pulmonary shunt and palliative reconstruction of right ventricle outflow tract, but it can not be found in cavopulmonary connection patients.
