Abstract: | After biopsy (n=6) and nephrostomy (n=1) of three native and four transplanted kidneys, gross hematuria, hypertension, and deterioration of function necessitated performance of transarterial embolization. Angiography revealed five arteriovenous fistulas (AVFs), one pseudoaneurysm, and one arteriocaliceal fistula. Superselective catheterization was accomplished using 5 Fr standard diagnostic catheters and 3 Fr coaxial Tracker catheters. Four of five AVFs were embolized successfully by inserting unfibered (2 patients) and fibered (2 patients) platinum coils (diameters 2 mm and 4 mm, respectively). For one AVF, additional injection of butylcyanoacrylate was necessary. The pseudoaneurysm was embolized successfully by such injection, and the arteriocaliceal fistula was occluded using one unfibered 2-mm coil. Embolization stopped the bleeding in all patients. One week after treatment, renal function was improved in 5 patients and remained unaffected in 2. Superselective embolization using Tracker catheters and fibered microcoils is an effective, safe treatment of renal vascular lesions. |
