Cost-Effective Day Surgery for Arteriovenous Fistula Stenosis: A Viable Model for Hemodialysis Patients.
Med Sci Monit

Department of Nephrology, Beijing Haidian Hospital (Haidian Section of Peking University Third Hospital), Beijing, China.
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.

BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) encompasses a group of disorders ranging from hyperplastic to malignant lymphoid proliferations in the post-transplant period owing to immunosuppression, often in the setting of EBV transformation. PTLD is a rare complication of immunosuppression that, like lymphomas, can have a variable presentation based on disease localization. We report a case of PTLD mass effect at the porta hepatis for the first time in the literature, resulting in hepatic artery stenosis (HAS) and common hepatic duct obstruction.

Objectives: As is well known, plaque morphology plays an important role in the hemodynamics of stenotic coronary arteries, thus their clinic outcomes. However, so far, there has been no research on how the cross-sectional shape of a stenotic lumen affects its hemodynamics. Therefore, this study aims to explore the impact of plaque cross-sectional shape on coronary hemodynamics under mild or moderate stenosis conditions (diameter stenosis degree ≤50 %).

The Islamia University of Bahawalpur, Bahawalpur, Pakistan.
The present article focuses on the analysis of the two-phase flow of blood via a stenosed artery under the influence of a pulsatile pressure gradient. The core and plasma regions of flow are modeled using the constitutive relations of Herschel-Bulkley and the Newtonian fluids, respectively. The problem is modeled in a cylindrical coordinate system.

Objectives: Vascular access (VA) stenoses play a significant role in the morbidity of the haemodialysed population. Classifications for diagnosis, assessment and proposal of treatment strategies can be useful clinical and methodological tools. This review aims to present a comprehensive summary and propose further methodological approaches.
