Transarterial embolisation of renal arteriovenous malformation: safety and efficacy in 24 patients with follow-up

Local recurrence of renal cell carcinoma that simulated multiple renal arteriovenous fistulas after laparoscopic partial nephrectomy: Report of a rare case

“…In the present case, however, the resolution of AVF symptoms was achieved without occlusion of all feeding vessels. This might be as a result of embolization of the specific bleeding foci within the whole AVF . It is also reported that the mean time to readmission with delayed hemorrhage as a result of AVFs and renal artery aneurysms was 16.8 days (range 9–30 days); however, AVFs were noted 3 months after laparoscopic PN in this case, which made the diagnosis of AVF as a true vascular malformation more questionable.…”

Nevertheless, the available data do not clearly define the association between initiation, timing or underlying etiological factors of AVFs.…”

Endovascular Treatment of 12 Cases of Renal Arteriovenous Malformations: The Experience of 1 Center and an Overview of the Literature

“…NBCA and Onyx are liquid embolic agents that can penetrate into the nidus of rAVMs to achieve complete embolization. 3,4 Ethanol is another liquid embolic agent. Hwang et al reported that congenital renal AVMs could be embolized with ethanol and coils effectively.…”

Use of angioembolization in urology: a review

“…These cases can be technically challenging for interventional radiologists as AV malformations often have high rate of blood flow. However, embolization techniques have been shown to be safe and effective in treating AV malformations, including those of congenital origin ( 35 - 37 ). Technical and clinical success rates vary from 67–87% ( 35 , 38 ).…”
