Abstract：Objective To explore the influencing factors associated to the development of pulmonary arteries in patients af-ter systemic-pulmonary shunt. Methods A retrospective study was performed on 142 patients that underwent systemic-pul-monary shunts in the General Hospital of Shenyang Military Command from January 2009 to June 2015. After 6 months,the pulmonary artery index( PAI) of patients was observed. Results All 142 patients received follow-up for mean 11 months ( ranged from 6 to 36 months) . During the follow-up period,the pulmonary artery and its branches of all the patients had dif-ferent levels of development. Among them,93 patients(65. 5%) underwent the second repair operation while the other 49 patients(34. 5%)were still waiting for the next operation. After 6 months,the total pulmonary artery index increased from a mean value of(124.5 ±24.6)mm2/m2 to(177.1 ±33.3)mm2/m2,and the difference was statistically significant(P <0. 01). PAI rate of change was 0 to 129. 8%,and the mean rate was(39. 7% ± 24. 1%). The age,disease,and large-main pulmonary collateral arteries( MAPCA) number and operation method were independently related factors affecting pulmonary index change rate. The age and operative method were the independent influencing factors of the second repair operation. Conclusion The age and operative method are the major influencing factors. If the patients undergo the systemic-pulmona-ry shunt as soon as possible,they will have more probability to undergo the second repair operation.
