Abstract:
Objective To evaluate the efficacy and safety of super-selective renal arterial embolization (SRAE) for treatment of huge renal angiomyolipoma (RAML).Methods Data of 16 patients with huge RAML treated with SRAE were retrospectively analyzed.The clinical symptoms,tumor size,serum creatinine and complications were compared before and after SRAE.Results A total of 26 SRAE treatments were performed on 16 patients with huge RAML.The technical success rate of SRAE was 100％ (26/26).Seven cases (7/16,43.75 ％) received one SRAE treatment,whereas 8 (8/16,50.00％) required two SRAE treatments.Only one case (1/16,6.25％) received three SRAE treatments.The mean follow-up period was (16.60± 15.60) months.The maximum diameter of the tumor reduced significantly after SRAE at final follow-up than before embolization ([9.00±2.80]cm vs [12.60±2.40]cm,t=12.41,P＜0.01).The symptoms of flank pain and hematuria gradually relieved after SRAE.And there was no statistical difference of mean serum creatinine before and after SRAE ([76.00±14.90]μmol/L] vs [79.10±12.80]μmol/L,t=0.89,P=0.39).Fourteen cases (14/ 16,87.50％) experienced post-embolization syndrome including varying degrees of fever,local pain or nausea on 1-3 days after embolization.No serious complications occurred.Conclusion SRAE is an effective method for stopping bleeding of ruptured huge RAML,as well as relieving symptoms and reserving nephron.
