[Permanent stop of renal circulation by embolisation with microspheres. Preliminary report (author's transl)].
The risk of tumor cell dislodgement during operative removal of carcinoma of the kidney is reduced by preoperative occlusion of the renal arteries. After the intraarterial injection of 250 mu microspheres a complete blockage of the intrarenal circulation was found in all three experimental animals for at least 2 hrs. In the other two dogs the blockage remained unchanged over 24 hrs. Subsequent experiments shall demonstrate that the simple embolisation technique using microspheres is more stable than other methods.
