Selective renal occlusion phlebography with a balloon catheter.

Technique of selective renal occlusion phlebography is described. For the temporary occlusion of the renal vein a Swan-Ganz or Dotter-Lucas balloon catheter are used. The balloon catheter is directed into the renal vein using a Desilets-Hoffmann or EDSLAB introducer. Occlusion of the renal vein is achieved by insufflation of 2-3 ml. air into the balloon of the catheter. Selective renal occlusion phlebography leads to optimal retrograde opacification of the renal venous system.
