Hi Everyone:rolleyes: Does anyone have any advice about Pneumataceles(Lung Cysts). MY son Corey who is still in hospital after 5 months(he was 3 months premature) may have to have one drained because it is continuing to grow and they do not want it to rupture. Is the procedure very dangerous? They are not very keen to do it in case he gets a Pneumothorax. Please can you tell me what the procedure involves? Thanks Catherine xxx
