Arteriovenous malformations of the kidneys: ablation with alcohol

Cirsoid renal arteriovenous malformation treated by endovascular embolization with n-butyl 2-cyanoacrylate

“…Several embolic agents have been proposed and applied: autologous clot; gelatin sponge [8]; stainless steel coils and platinum microcoils [9]; alcohol [12]; and NBCA [10]. If the rAVM is supplied by one distinct arterial feeder, occlusion of this feeder with one of these materials will most probably ensure thrombosis of the nidus.…”

Renal Ablation with Absolute Ethanol for Nonfunctioning Hydronephrosis

“…It is recog nized to be useful as a palliative treatment to improve the quality of life of the patients with advanced renal cell carci noma, though the issue regarding improvement of survival time is still controversial [3][4], Ablative TAE-RA is also widely utilized for nonmalignant renal diseases aiming at occlusion of renovascular lesions such as arteriovenous malformations or fistulas [5], aneurysms [6] and uncon trollable renal bleeding caused by renal trauma [7] includ ing renal biopsy, PNS and percutaneous nephrolithotomy, and for control of hypertension in end-stage renal disease [9] and urinary fistula [10], Thus, TAE-RA has been shown to be safe and effective in ablation of the kidney in high-risk patients, preserving their quality of life.…”

Ethanol Embolization of Arteriovenous Malformations: Interim Results

“…With use of these agents, however, it is difficult to control the level of occlusion, and it has also been reported that lesions treated with isobutyl 2-cyanoacrylate and n-butyl cyanoacrylate can recanalize (10,11). Superselective catheterization or direct puncture of the nidus and the use of ethanol as a permanent embolic agent have shown good clinical and radiologic implications by improving AVM treatment with an acceptable risk of morbidity (12)(13)(14)(15).…”
