[Percutaneous recanalisation of chronic arterial occlusions (Dotter principle) with a new double lumen dilatation catheter (author's transl)]

Abstract

A modification of Dotter's transluminal recanalisation of stenoses and occlusions of the superficial femoral artery, and of stenoses of the iliac artery, is described. In this procedure the occluding material is compressed not by successive catheters, but by a catheter with a dilatable cover. This catheter consisted originally of a single lumen, but now has double lumen; one lumen accomodates contrast, or a guide wire or a stiff cannula, whereas the second lumen is used for filling the cover and the expandable segment. The procedure is described in detail. Results so far appear satisfactory; they are compared with the results which have been obtained during the last year with the single lumen catheter.
