[Complications during long-term control of the pressure in the pulmonary artery]

It is reported on two rare complications occurring in the pulmonary catheterisation with long-term control of the pressure of the pulmonary artery. In case 1 in confluenting bronchopneumonias the formation of an abscess in the region of the point of the catheter developed, in which case by the infusion therapy with very peripheral position of the catheter local lesions are very probable. In case 2 the catheter via an atrial septum defect passed into a pulmonary vein in PCA-position. A haemorrhagic infarction of the lung developed. In the two cases after removal of the catheter and adequate therapy the pulmonary complications healed.
