Digital angiography in the pediatric patient with congenital heart disease: comparison with standard methods.

摘要: Digital subtraction angiography (DSA) permits high-resolution cardiac imaging with relatively low doses of contrast medium and reduced radiation exposure. These are potential advantages in children congenital heart disease. Computer-based DSA (30 frames/sec) conventional cutfilm (6 or cineangiography (60 were compared 42 patients, ages 2 months to 18 years (mean 7.8 years) weighing 3.4 78.5 kg 28.2 kg). There 29 diagnoses that included valvular regurgitant lesions, obstructive various shunt abnormalities, a group miscellaneous anomalies. For injections made at site distant from the lesion on right side circulation, mean dose was 60% 100% given during standard angiography. With close left 27.5% 42% dose. Radiation exposure for each technique markedly all age groups. A total 92 digital angiograms performed. Five studies suboptimal because too little injected; remaining 87 injections, resulted identical 81 instances (p less than .001 vs chance). The six failed confirm angiographically by cineangiography. We conclude usually provides diagnostic information equivalent available cineangiography, but requires considerably lower methods.
