Eisenmenger's syndrome--True are all except:: (A) Pulmonary veins are not distended, (B) RV and LV walls come back to normal size, (C) Dilatation of central pulmonary artery, (D) Peripheral pruning of pulmonary arteries
Answer is B. b. RV and LV walls come back to normal size(Ref: Nelson's 20/e p 2242, Ghai 8/e p 428)In Eisenmenger syndrome, irreversible pulmonary vascular obstructive changes occur;There is mainly pulmonary arterial hypertension, so pulmonary veins are not distendedBecause of pulmonary hypertension, right ventricular hypertrophy occursChest X Ray shows that pulmonary vessels are enlarged in the hilar areas and taper rapidly in caliber in the peripheral branches (peripheral pruning).
