Zusammenfassung
Die Lunge ist durch eine duale Gefäßversorgung charakterisiert. Die Existenz einer
bronchial-arteriellen Versorgung wurde bereits im 2. Jahrhundert von Galen vermutet.
Angiographische Studien zeigen, dass unterschiedliche Lungenläsionen eine unterschiedliche
Gefäßversorgung aufweisen. Mithilfe der Farbdopplersonographie können Lungenarterien
durch Ortslage, Flussrichtung und quantitative Spektralkurvenanalyse klassifiziert
werden. Dieser Artikel will die Pathophysiologie sowie Grundlagen der Farbdopplersonographie
von Lungengefäßen darstellen.
Abstract
Anatomically, the lung is characterised by a dual blood supply. The existence of a
systemic bronchial arterial supply to the lung in addition to the pulmonary arteries
was first described by Galen in the second century. From angiographic studies it is
known that pulmonary lesions of different aetiologies are characterised by differences
in arterial supply. Colour Doppler sonography makes it possible to classify pulmonary
arteries by location, flow direction, and quantitative spectral curve analysis. This
article will review pathophysiological and colour Doppler sonographic basics of pulmonary
vascularity.
