13th Annual Global Embolization Symposium & Technologies
Purpose : To evaluate the effectiveness of endovascular embolization as a therapeutic technique in iatrogenic renal vascular injuries.
Material and Methods : This work included 64 patients (50 males and 14 females) between the ages of 3 and 60 years (mean age 37 years) with suspected renal vascular injury after renal intervention. They were underwent angiography and percutaneous transcatheter arterial embolization using coils and glue.
Results : The source of bleeding was identified and embolized in 56 (87.5%) of patients (pseudoaneurysm=34, pseudoaneurysm with arteriovenous fistula=14, arteriovenous fistula (AVF) alone= 4 and extravasation=4).
Bleeding stopped in 54 of the 56 patients (96.4 %). In two patients (3.6%), recurrent bleeding occurred. Re-angiography and assessment was done and insertion of another coil was needed in one patient, while in the second one, glue was administrated. None of the patients underwent embolization required further surgical intervention. No significant immediate or delayed complications related to angiography or embolization was recorded.
Conclusions : Selective renal embolization is a safe and effective treatment for iatrogenic renal vascular injury with maximum preserve of renal tissue and function. Now it is considered the first treatment option in cases of the renal vascular injuries
