[Development and clinical use of blood microfilters]

Special microfilters made on the basis of meshy and not woven materials were used for the prevention of microembolic complications in hemotranfusions and perfusions. The results of testing and clinical use of the filters in patients during and after extracorporal perfusions following operations on the open heart are described. The advantages of not woven materials over meshy material for the filtration are shown. The postoperative course in 184 patients after the application of blood microfilters is analyzed. The positive effect is shown.
