Zusammenfassung
Bei der Lungenperfusionsszintigraphie einer Patientin mit Vena-cava-superior-Verschluß fand sich eine deutliche MAA-Anreicherung in Teilen der Leber. Als Ursache konnte ein Kollateralkreislauf über Venen der Abdominalwand und eine rekanalisierte Vena umbilicalis ermittelt werden. Unter externer Bestrahlung von Lymphomen des oberen Mediastinums kam es zu einem raschen Rückgang des cavo-portalen Shunt-Volumens.
Summary
Lung perfusion scintigraphy in a patient suffering from superior vena cava obstruction showed distinct MAA uptake in parts of the liver due to a collateral blood flow through abdominal parietal veins and a recanalized umbilical vein. Radiation therapy of mediastinal lymphomas was followed by a rapid decrease of caval portal shunt volume.
