Preoperative arterial occlusion in renal tumors: 3 years experience

The authors describe their experience in preoperative embolization of 42 renal neoplasms. In all cases but one Gelfoam has been used for arterial occlusion with just a few and transient complications. Good hemostatic effect and décollement have been obtained irrespective of the diameter and vascularization of the tumor. To avoid late décollement difficulties and reduce the duration of clinical sequels the authors prefer, at present, to resort to surgery within 24 hours of embolization.
