Abstract
<p>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. </p>
Highlights
We write to report a case of pulmonary haemorrhage and baffle thrombosis post sinus venosus atrial septal defect (SV-ASD) repair diagnosed utilising a novel imaging protocol of contrast enhanced dynamic Pulmonary Computed Tomography Perfusion (PCT-P) scan
Operative findings revealed a SV-ASD of 2.5cm high in the atrial septum with anomalous drainage of the right upper and middle pulmonary veins into the lowermost portion of the superior vena cava
It was hypothesised that the pressure increase may have arisen at the time of initial operation subsequent to placement of the surgical clamp on the upper pulmonary artery, suddenly increasing the pressure and blood volume to the lower pulmonary arteries resulting in haemorrhage
