    INPUT: Low lung volumes are present . Small left pleural effusion is relatively unchanged compared to the prior study . Left basilar patchy opacity likely reflects atelectasis . Suture material within the left lung apex is unchanged . Mild right basilar atelectasis is redemonstrated . There is crowding of the bronchovascular structures but no pulmonary edema is present . No pneumothorax is identified . There are no acute osseous abnormalities . Subcutaneous gas within the left lateral chest wall soft tissues has decreased in the interval .
