ABSTRACT
Objective To evaluate the application of flexible thoracoscopy in the diagnosis of pleural effusion.Methods Thoracoscopy was performed in 20 pleural effusion patients in our hospital from May to December 2007.Biopsies were performed in 16 patients,not in the other 4 patients since difinite diagnosis had been reached before thoracoscopy.Results Rate of accurate diagnosis via thoracoscopy was 93.75%(15/16).Results Of biopsy were as follows:adenocarcinoma 8 cases,squamous carcinoma 1 case,adenosquamous carcinoma 1 case,malignant pleural effusion 1 case,tuberculous pleuritis 4 cases,malignant mesothelioma 3 cases,chronic suppurative pleuritis 1 case,failed diagnosis 1 case.Presentations of lesions under thoracoscope were as follows:diffused miliary nodules 10 cases(10/20),multiple mass 7 cases(7/20),fibrous compartmentation or conglutination 9 cases(9/20).There were no severe complications.Conclusion Flexible medical thoracoscopy is a safe and efficient method of etiologic diagnosis of pleural effusion.
ABSTRACT
Objective To probe into the angiographic signs and the variations of bronchial arteries for pulmonary tuberculosis or bronchiectasis with massive hemoptysis.Methods 25 patients with pulmonary tuberculosis and 15 patients suffered from bronchiectasis accompanied by massive hemoptysis were undertaken bronchial arterial embolization(BAE).All patients were embolized with gelfoam including 32 with spring coils in addition. Results 63 arteries demonstrated angiographic signs of hemoptysis in 40 patients.The immediate stanching rate was 92.5%(37/40). The bronchopulmonary shunt formation sign shown by angiograph was the major feature of tuberculosis(P=(0.0528)) and the enlarged tortuous arteries in bronchiectasis were more to be demonstrated than in tuberculosis(P
