RADIOLOGY MCQ----OLIGAEMIA

341. Central cyanosis may be present within a few hours

 after birth in

a. tetralogy of Fallot

b. uncorrected transposition of great arteries (UTGA).

c. common atria and common ventricles 

d. PDA

e. persistent truncus arteriosus

434.All are causes of oligaemia except
A Ebstein's anomaly
b. Tetralogy of Fallot
c. Uncorrected transposition of the great arteries with atrial or venous septal defect
d. Uhl's disease

e. persistent truncus --Type IV

Table   -- INCREASED PULMONARY PERFUSION (PLETHORA)

Level of shunt	Anomaly
Atrium	Ostium primum defect[*]
	Ostium secundum defect[*]
	Sinus venosus defect
	Anomalous pulmonary veins[†]
Atrioventricular valves	Endocardial cushion defects
	Ostium primum defect[*]
	Muscular ventricular septal defect (VSD)[*]
Ventricles	Membranous VSD[*]
	Bulvar VSD[*]
	Double outflow ventricle
	Single ventricle
Aorta	Patent arterial duct[*]
	Aortopulmonary window
	Common arterial trunk (persistent truncus arteriosus)[†]
	Coronary artery-to-right heart fistula
	Uncorrected transposition of the great arteries with atrial or venous septal defect

*	Most common causes of plethora without cyanosis;
†	most common causes of plethora with cyanosis.

  -- DECREASED PULMONARY PERFUSION (ANOMALY)

Level of abnormality	Anomaly
Tricuspid valve	Tricuspid atresia
	Tricupid stenosis
	Ebstein's anomaly
Right ventricular outflow	Pulmonary infundibular stenosis (severe)
	Pulmonary valvar stenosis (severe)
	Tetralogy of Fallot
	Uhl's disease (right ventricular hypoplasia)
Pulmonary arterial	Pulmonary artery or trunk atresia
	Right or left pulmonary artery interruption
	Peripheral pulmonary artery interruption or stenosis
	Common arterial trunk (persistent truncus) (Type IV)
	Transposition (ventriculo-arterial discordance) with pulmonary valve stenosis
	Eisenmenger reaction (lung periphery only) REF -- Adam: Grainger & Allison's Diagnostic Radiology, 5th ed. CHAPTER 23 – Congenital Heart Disease: General Principles and Imaging
