Venous Baffle Thrombosis and Pulmonary Haemorrhage Following Atrial Septal Defect Repair Diagnosed Utilising a Novel Imaging Technique of Dynamic Pulmonary Perfusion Computed Tomography

Jason Nogic, Dennis Wong, Marcus Crosset, John Troupis


Perfusion Computer Tomography is becoming a more utilised technology in the diagnosis of vascular abnormailities in medicine. We report a case of pulmonary haemorrhage and baffle thrombosis post sinus venosus atrial septal defect (SV-ASD) repair in a 56 year old patient diagnosed utilising a novel imaging protocol of contrast enhanced dynamic Pulmonary Computed Tomography Perfusion (PCT-P) scan. This novel protocol facilitated the diagnosis and subsequent surgical thrombectomy and conduit repair, leading to full recovery of the patient where traditional computer tomography pulmonary angiography, bronchoscopy and surgical exploration did not reveal a diagnosis.
