Background And Purpose: Long-term patency in untreated experimental aneurysms represents a critical attribute of any system proposed for the testing of aneurysm occlusion devices. Our purpose was to evaluate the long-term patency in elastase-induced saccular aneurysm models in rabbits.
Methods: Serial intravenous digital subtractive angiography (IVDSA) was performed in 20 elastase-induced saccular aneurysm models in rabbits 1, 3, 6, 9, 12, and 24 months after creation. Aneurysm dimensions, including neck diameter, width, and height, were measured and calculated from IVDSA images. Comparisons of the aneurysm sizes across time were performed by using the paired Wilcoxon signed rank test and the Friedman test.
Results: None of the 20 aneurysms showed spontaneous thrombosis at any time point. Mean dimensions did not change over time for any parameter. Mean aneurysm neck, width, and height were not significantly changed at interval evaluations of 1, 3, 6, 9, 12, and 24 months (P = .210; P = .413, and P = .405, respectively).
Conclusion: Long-term patency in elastase-induced saccular aneurysm models in rabbits is excellent. Aneurysm dimensions remain stable for as long as 2 years following creation.

Long Term Results of a Comparative Study of Percutaneous and Surgically Created Proximal Forearm Arteriovenous Fistulae.
Eur J Vasc Endovasc Surg

Department of Surgery, Division of Vascular and Endovascular Surgery, University of California, San Francisco, CA, USA.
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.

Background: Liver cirrhosis accounts for more than 90 % of portal hypertension cases, and the other cases are due to noncirrhotic portal hypertension (NCPH). Variceal bleeding is the most life-threatening complication of portal hypertension and its primary treatment is medical according to the Baveno VII guidelines. This review discusses the evidence on surgical portal decompression for adult patients with NCPH secondary to chronic extrahepatic portal vein obstruction (EHPVO).

Department of Surgery, University Hospital Centre Zagreb, Zagreb, Croatia.
Objectives: Brachial artery injury due to displaced supracondylar fracture (SC) of the humerus in children may present with pink pulseless hand (PPH), denoting a well perfused hand without radial pulse, or acute hand ischemia. Some reports state that brachial artery reconstruction is not necessary in children with persisting PPH, but the reports on long-term consequences such as intermittent claudications, growth retardation and ischemic contracture in children with pulseless hand are scarce and often misinterpreted. The objective of our analysis was to assess the long-term outcomes of children with brachial artery injury associated with SC fracture.

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.
