TRANSARTERIAL EMBOLIZATION CONGENITAL RENAL ARTERIOVENOUS MALFORMATION AT HANOI MEDICAL UNIVERSITY HOSPITAL
Main Article Content
Abstract
Objective: To evaluate the effectiveness and safety of transarterial embolization (TAE) of congenital renal arteriovenous malformations (AVMs) using histoacryl and/or VXKL. Materials and Methods: A cross-sectional descriptive study on 11 patients with congenital renal AVMs were treated using histoacryl and/or VXKL via transarterial access was investigated for clinical presentation, imagine features, treatment methods and complications in Hanoi Medical University Hospital between February 2020 and May 2024. Results: 11 patients (5 women and 6 men; mean age, 50.6 y) with 8/11 gross hematuria, and 4/11 flank pain. Among the 11 patients, 8/11 AVMs had high-flow lesions. TAE was performed with histoacryl in 3 patients, VXKL with histoacryl in 7 patients, and VXKL in 1 patient. Technical success rate was 91% (10/11), and clinical success rate was 100% (11/11). Of the 11 patients treated, the infarcted renal areas were 2.1%–20.4% (mean, 9.8%). No complications were observed post-intervention. Renal function was normal in all patients pre - embolization and post – embolization. Conclusions: Embolization of congenital renal AVMs via transarterial approaches using histoacryl and/or VXKL was safe and effective and elicited good outcomes.
