Unformatted text preview: and 10 Hypoplastic Tricuspid atresia. Usually with pulmonary atresia or stenosis. Underdeveloped RV. Common features are small RV with right-to-left shunting through an ASD causing cyanosis. right heart Imaging sequence of at risk infants (neonateor 99mTc-GH. If positive, ultrasound and or voiding cystourethrogram. Nuclear scan with 99mTc -DMSA to 3 years) for suspected pyelonephritis? Imperforate or ectopic anus Range from simple membranous anal atresia to arrest of colon as it descends through puborectalis sling. Fistula formation may occur to genital or urinary tract.

Infant GERNuclear imaged with Tc-99m sulfur colloid formula (best sensitivity) is best scintigraphy. Intussusception Generally occur a fter 6 months of age. Most are ileocolic and the cause is idiopathic. Treatment is water-soluble or air enema reduction. Contraindicationsto enema reduction: Free air, Signs of peritonitis. Recurrent intussusception occurs in 5% to 10% of cases. Unilateral hyperexpansion of body. Hilar lobes in children, common causes Aspirated foreign one or two nodes compressing bronchus. Hyperinflated lung findings Flattening or inversion of diaphragm. Widening of rib interspaces. Larger retrosternal and retrocardiac clear spaces.

MalrotationDuodenal-jejunal junction is not properly fixed by ligament of Treitz. Results in duodenal obstruction by peritoneal bands or twisting of duodenum (midgut volvulus). Meconium Aspiration Intrauterine fetal distress can lead to passage of meconium. Aspirated meconium particles cause obstruction of small peripheral bronchioles. Results in areas of subsegmental atelectasis and areas of overdistension. Coarse reticulonodular...
