- W2355363024 abstract "Objective To study the clinical value of renal angiography and pre-operative renal artery embolization in advanced renal cancer. Methods A total of 36 patients with advanced renal cancer were definitely diagnosed by IVP,US,CT or MRI examination. A 5F Yashiro catheter was introduced into the femoral artery with Seldinger's technique under local anesthesia,abdominal aortagraphy and renal arteriography in both sides of kidneys were performed routinely to display the blood supplying arteries of tumor,thereafter,renal embolization was performed under superselective catherization for chemotherapeutic embolizingembolization group. Then the clinical effect was observed,the amount of blood loss and the operation time were recorded. All these results were compared with that of randomly selected 17 patients before surgical operation(control group) with advanced renal cancer admitted during the recent 3 years but without embolization. Results Angiography showed enlargement of arteries for supplying blood to renal tumor characterized with displacing branches and irregular twisting neo-vessels,some of which were reticular and encircled. Tumor vessels and tumor staining were seen. In only a few cases,the mottling blood reservoir and mini a-v fistula were found. The formation of cancer embolus were presented in renal veins and inferior vena cava during the venous and parenchymal phase. In embolization group,the amount of blood loss during operation was 0 ~ 600 mlmean 310 ml and the operation time was 60 ~ 150 min mean 90 min ,while that in control group were 0 ~ 1 600 ml mean 480 ml and 80 ~ 195 min mean 120 minl respectively. The amount of blood loss and the operation time in the embolization group were markedly less than that in the control group. In embolization group,the tumor mass softened,its surface looked pale and the peripheral superficial veins shrinked,the perivenal edema zone was formed and easy to strip. The post-operative pathological examination showed that in embolization group the amount of tumor cells were markedly decreased and the tumor cells presented with different extent of degeneration necrosis and liquifying. Conclusion The pre-operative embolization of target vessels is the most effective accessory treatment in advanced renal cancer,it can increase the resection rate,decrease the risk of operation and bleeding amount during operation." @default.
