[Diagnosis and therapy of lung abnormalities: current status]

Malformations of the lung must be detected early before the onset of complications. Therefore invasive diagnostic techniques are increasingly being replaced by less complicated methods such as sonography, colour-coded Doppler sonography, DSA and CT. In certain cases, angiography and thoracoscopy should not be renounced. The use of these methods is preferred in combination with nonoperative techniques: embolisation in av-aneurysms, endoluminal endoscopic resection of congenital bronchial stenoses, stabilization of the bronchial wall in valve mechanisms or thoracoscopical resection of a cyst using fibrin glue to seal the area of resection. These endoscopical procedures are simplified by the application of laser. The smaller the child the more obvious it's advantages.
