lung perfusion spect: application in a patient with tetralogy of fallot and suspected pulmonary thromboemboli
a 22-year-old woman presented with acute left-sided pleuritic chest pain and dyspnea 6 days after surgery for revision of the stenotic central aortopulmonary shunt. she had a history of tetralogy of fallot (tof), pulmonary valve stenosis, ventricular septal defect and major aortopulmonary collateral artery. her waterston shunt was placed when she was 5 years old and stented and re-dilated after...
متن کاملPulmonary ventilation and perfusion abnormalities and ventilation perfusion imbalance in children with pulmonary atresia or extreme tetralogy of Fallot.
Xenon-133 lung ventilation and perfusion scans were done preoperatively after cardiac catheterization and cineangiocardiography in 19 children; 6 had pulmonary atresia with an intact ventricular septum and hypoplastic right ventricle, 4 pulmonary atresia with associated complex univentricular heart, and 9 extreme Tetralogy of Fallot. The four patients with discrepancies in the sizes of the left...
متن کاملPulmonary perfusion abnormalities and ventilation-perfusion imbalance in children after total repair of tetralogy of Fallot.
The pulmonary perfusion of 25 children who had total surgical correction of tetralogy of Fallot was evaluated by radionuclide perfusion scans. In addition, 18 had 133Xe ventilation studies. Eighteen of the children previously had palliative systemic-pulmonary shunts; 14 had aortic-pulmonary shunts (Waterston or Potts-Smith) and four had Blalock-Taussig shunts. Seven children had single stage to...

متن کاملAbsent pulmonary uptake on 99mTc MAA perfusion lung scan due to severe right-to-left shunt.
c 5 XTRAPULMONARY accumulation of Tc macroaggregated albumin (MAA) is rarely een on perfusion lung scan, and has been reported n less than 4% of a study population of nearly 380 atients.1 It occurs when the agent bypasses the ungs due to a right-to-left (R-L) cardiac or pulonary shunt, when it is shunted to the portal vein efore reaching the right atrium and ventricle of he heart, and when the ...
