BACKGROUND: Injured phrenic nerve secondary to cardiac surgeries is the most common cause of @entity4589 ( @entity4589 ) in @entity1 . The aim of this study was to determine the risk factors for @entity4589 caused by @entity4297  corrective  surgeries in pediatrics. METHODS: This cross-sectional study, conducted in a 2-year period (2006-2008), included 451 @entity1 with congenital @entity299 admitted to the Pediatric Cardiac Surgery Ward of Imam Khomeini Hospital. The diaphragmatic function was examined via fluoroscopy, and the frequency of @entity4589 and its relevant parameters were evaluated. RESULTS: Of the 451 @entity1 , comprising 268 males and 183 females at an age range of 3 days to 204 months (28.2    33.4 months), 25 (5.5%) @entity1 (60% male and 40% female, age range = 15 days to 132 months, 41.2    28.1 months) had @entity4589 as follows: 48% unilateral right-sided and 36% unilateral left-sided. Additionally, 68% had @entity299 and 84% had @entity4589 following total correction surgery. The highest prevalence rates of @entity4589 resulting in @entity1269 were observed after arterial switch operation, Fontan procedure, and Blalock-Taussig shunt surgery, respectively. Thirteen (52%) of the 25 @entity4589 @entity1 underwent surgical diaphragmatic plication because of severe @entity649 and dependency on mechanical ventilation, and most of the cases of plication underwent arterial switch operation. The rate of mortality was 24% (6 @entity1 ). CONCLUSION: @entity4589 with a prevalence of 5.5% was one of the most common complications secondary to cardiac surgeries in the @entity1 included in the present study. Effective factors were age, weight, cyanotic @entity4297 , and previous cardiac surgery. Diaphragmatic plication improved prognosis in severe cases.
