Background: High resolution CT scan (HRCT) and its score have an important role in delineating pathological changes and pulmonary functional impairment in patients with bronchiectasis. Aims: To assess pulmonary function tests (PFTs) in patients with cystic and cylindrical bronchiectasis. To correlate HRCT score with PFTs and systolic pulmonary artery pressure (SPAP) in both radiological types. Materials and Methods: A cross-sectional study of patients with bronchiectasis diagnosed by HRCT was conducted at King Khalid University Hospital, Riyadh, Saudi Arabia. PFTs, HRCT score and SPAP were measured in both types. Results: We studied 94 patients with bronchiectasis: 62 were cystic and 32 were cylindrical. Their mean age was 53.417.5 SD years. Forced vital capacity (FVC %) and forced expiratory volume in 1 second (FEV1%) were significantly lower in cystic patients ( P < .0001) compared with cylindrical and Diffusion capacity (DLCO %) was also significantly lower ( p < 0.01). In cystic group PaO2 was significantly lower and PaCO2 higher ( P < 0.0001). HRCT score was correlated with FEV1% (r= -0.51). HRCT score was significantly lower in the cystic group ( P =0.002)and correlated with SPAP ( r =0.23). Global HTCT score of 10.32.5 was associated with SPAP ≥40mmHg( P =0.011). Conclusion: Patients with cystic bronchiectasis have significant impairment of pulmonary physiology compared with cylindrical bronchiectasis patients. HRCT score correlated with PFTs and SPAP.
