Abstract
- Total 32 cases of pulmonary atresia were diagnosed radiographically at Seoul National Uniersity Hospital fromMarch 1979 to August 1982. Some characteristic radiological findings were analyzed in chest PA andcineangiograhies. The resusls were as follows; 1. In the evaluation of chest PA, cardiomegaly was noticed in 16cases, dextrocardia in 8 cases, elevated cardiac apex in 7 cases and right-side aortic arch in 6 cases. Thepulmonary vascularties were mildly decreased in 20 cases, markedly decrased in 9 cases and decreased withreticular pattern in 3 cases. 2. As final diagnoses after cineangiography, pulmonary atresia was associated withTetralogy of Fallot variant in 17 cases, transposition of great vessels in 7 cases, single ventricle in 5 cases,tricuspid atresia in 2 cases and intact ventricular septum in 1 case. 3. The classification according to thepattern of pulmonary artery is main pulmonary trunk with PDA(Type Ia) in 10 cases, pulmonary arterial confluencewith PDA(Type Ib) in 10 cases, no pulmonary arterial confluence with PDA (Type Ic) in 5 cases, main pulmonarytrunk without PDA(Ttpe IIa) in 0 case, pulmonary arterial confluence without PDA (Type IIb) in 5 cases, and nopulmonary arterial confluence without PDA (Ttpe IIc) in 2 cases. 4. Pulmonary wedge venography was done andsuccessful in 8 cases. Among them, confluence between right and left pulmonary arteries was noticed in 5 cases. 5.Biventricular cineangiography and/or pulmonary wedge venography, if necessary, is essential for the accuratediagnosis of pulmonary atresia to demonstrate detailed anatomy of pulmonary artery.
