“…Five year mortality rate % FFS = 0 : Mild disease ; is seen without any of these factors 11,9% FFS= 1 : Severe disease ; presence of one factor 26% FFS ≥ 2 : very severe disease, two factors or more 46% In pre-operative evaluation of patients with CSS, pulmonary function tests (PFTs) in symptomatic patients are necessary to predict peri-operative and post operative pulmonary complications, our patient had been diagnosed with asthma for the last 8 years, but her asthma is usually well controlled with inhaled salbutamol and inhaled symbicort and the last asthma attack goes back more than 6 months.
