Preoperative renal artery infusion chemoembolization for intermediate-and advanced-stage renal carcinoma / 医学研究生学报

ABSTRACT

Objective:It is difficult to separate intermediate-and advanced-stage renal carcinoma,and in some cases even harder to totally remove it.This study aimed to assess the effect of the renal artery infusion chemoembolization on intermediate-and advanced-stage renal carcinoma before surgery.Methods: Twenty-seven patients with intermediate-or advanced-stage renal carcinoma accepted the Sandwich mode of selective bronchial renal artery embolization 3-7 days before surgery.Then we analyzed both the methods of embolization and surgery after intervention therapy.Results: All the patients were successfully treated by transarterial embolization.During the operation,renal artery pulsatility significantly decreased or even disappeared,with obvious swelling of the surrounding renal tissues but very little bleeding.Conclusion: Preoperative chemoembolization for intermediate-and advanced-stage renal carcinoma can improve surgical conditions,shorten the operation time,decrease bleeding and elevate the success rate.
