Eisenmenger syndrome–True are A/E –
Pulmonary veins are not distended
RV & LV walls come back to normal size
Dilatation of central pulmonary artery
Peripheral pruning of pulmonary arteries
The characteristic pathological pulmonary vascular changes that develop in a patients with Eisenmenger syndrome are confined to arteries only and involve small pulmonary arterioles and muscular arteries (veins are not involved).
There is right ventricular hypertrophy (RV walls do not come back to normal size).
On x-ray there are dilated and prominent central arteries with rapid tapering (pruning) of the peripheral vasculature.
