Atelectasis is a common condition with lung cancer.
In our study, 36.8% of patients had atelectasis,
and 48.3% had atelectasis and obstructive pneumonitis.
Those results are in accordance with previous
findings (2,6,11). In pulmonary carcinoma, atelectasis
is usually developed due to endobronchial obstruction
but less frequently due to compression of tumor
or pleural effusion. It is known that vascular shunts
develop in atelectatic areas (12).
