Background: We evaluated the incidence and history of arteriovenous fistula (AVF) after kidney biopsy and assessed the use of superselective embolisation for treatment.
Methods: Case report of a 10-year-old boy with nephrotic syndrome. Renal biopsy (RB) in this patient was complicated with AVF. Immediately after RB was undertaken, microscopic haematuria was observed, within 48 hours after the biopsy life-threatening haematuria due to pseudoaneurysm started. Renal angiography was carried out, which demonstrated a hyperthrophic aberrant artery in the region of the bottom pole of the left kidney, from which blood was instantaneously flowing through a high-flow arteriovenous fistula (AVF).
Results: Embolization was carried out using small platinum coils (MWCE-18S-3/2, -18S-4/2, -18S-5/2TORNADO Embolization Microcoil) and the tissue adhesive Histoacryl.
Conclusions: The technique of superselective embolisation using coaxial catheter is a safe method in the treatment of post biopsy AVFs and pseudoaneurysm (Fig. 3, Ref. 6).

Introduction: Arteriovenous (AV) fistula creation is the most common surgical procedure for providing vascular access for haemodialysis in patients with chronic kidney disease (CKD). The functioning of fistula dictates the quality of dialysis and the longevity of patients. The most common circumstances that require surgical takedown of AV fistula are thrombosis and rupture.

Objective: This retrospective, single centre, comparative effectiveness study aimed to compare the long term outcomes of percutaneous arteriovenous fistulae (pAVF) and surgically created arteriovenous fistulae (sAVF) created in the proximal forearm for haemodialysis access.
Methods: Data were reviewed from a prospectively maintained database on patients who underwent pAVF or sAVF creation from September 2017 to September 2023. A total of 217 pAVFs (61 WavelinQ and 156 Ellipsys) and 158 sAVFs were analysed.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.

BACKGROUND For patients with end-stage renal disease, arteriovenous fistulas (AVFs) are often used for hemodialysis, but stenosis can impair their function. Traditional inpatient procedures to address AVF stenosis are effective but resource-intensive, prompting the need for alternative approaches like day surgery to optimize care and reduce costs. This study evaluated the feasibility of a day surgery model for AVF stenosis treatment in maintenance hemodialysis (MHD) patients, aiming to develop a cost-effective and high-quality care model.

: The autologous arteriovenous fistula (AVF) is the preferred choice for vascular access in patients with end-stage kidney disease (ESKD) undergoing maintenance hemodialysis. However, in the long term, the primary patency of AVF is suboptimal, with an AVF failure of approximately 30% in one year. The aim of this study is to examine how the pre-operative baseline levels of interleukin-6 (IL-6) affect long-term AVF failure.
