Interview With Radiologist On Lucy Letby & Air Embolism

An anonymous general radiologist with decades of NHS experience and neonatal unit work presents a detailed radiological analysis of the air embolism diagnosis. Using the Lee and Tanswell 1989 paper's single published X-ray image, he explains what true intravascular air embolism looks like radiologically — a dramatic retrograde air-dancer pattern filling the inferior vena cava, renal veins and hepatic vessels — and argues this bears no resemblance to what was documented in the Letby cases. He describes CT cases from his own practice where significant volumes of air were accidentally injected during contrast procedures, and notes that patients survived without long-term harm even after 150ml of injected air, undermining the prosecution's theory of a lethal small-volume injection. He places the case in the context of radiology's evolution towards a culture of discrepancy-reporting and learning from error, contrasting this with the hospital culture at the Countess of Chester. He argues air embolism as a diagnosis in these cases is symptomatic rather than pathological — a surface observation, not a demonstrated mechanism.

Ray (anonymous radiologist)

When you have true venous air embolism, the X-ray shows something extraordinary — air filling the vena cava, the renal veins, the liver vessels. You do not miss it. It is not a subtle finding. That picture was not there in these cases.

Ray (anonymous radiologist)

I have seen one hundred and fifty millilitres of air power-injected into a patient by accident. They were intubated for two days and made a full recovery with no residual effects. The prosecution theory requires a tiny fraction of that volume to be lethal. The two things are not compatible.

Ray (anonymous radiologist)

Air embolism was the preferred diagnosis for sudden collapse. But preferred does not mean demonstrated. It is a symptomatic label, not a pathological finding. Nobody did the imaging that would prove or disprove it.
