[Pleural drainage in acute thoracic trauma. Comparison of the radiologic image and computer tomography]
1Radiologische Universitätsklinik, Abt. Röntgendiagnostik, Universitätskrankenhaus Eppendorf, Hamburg.
Purpose:
Estimation of chest tube placement in patients with thoracic trauma with regard to chest tube malposition in chest radiography in the supine position compared to additional computed tomography of the thorax.
Material And Methods:
Apart from compulsory chest radiography after one or multiple chest tube insertions, 31 severely injured patients with thoracic trauma underwent a CT scan of the thorax. These 31 patients with 40 chest tubes constituted the basis for the present analysis.
Results:
In chest radiography in the supine position there were no chest tube malpositions (n = 40); In the CT scans 25 correct positions, 7 pseudo-malpositions, 6 intrafissural and 2 intrapulmonary malpositions were identified. Moreover 16 sufficient, 18 insufficient and 6 indifferent functions of the chest tubes were seen.
Conclusion:
In case of lasting clinical problems and questionable function of the chest tube, chest radiography should be supplemented by a CT scan of the thorax in order to estimate the position of the chest tube.
