Classifications of haemodialysis vascular access stenosis: a scoping review.
BMJ Open
January 2025
Charles University Third Faculty of Medicine, Prague, Czech Republic
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.

Hemodialysis (HD) access for patients with end-stage renal disease is a steadily increasing necessity, and maintaining patency of native or synthetic fistulas can be challenging. The main physiologic changes of an HD access that cause it to fail are inflow or outflow vessel stenosis or access thrombosis. These are propagated by factors intrinsic to end-stage renal disease, altered hemodynamics from a fistula, and typically further exacerbated by associated comorbidities.

Pediatric Heart Lung Center and Section of Pulmonary Medicine, Department of Pediatrics, University of Colorado Anschutz School of Medicine and Children's Hospital Colorado, Aurora, CO.
Objective: To characterize clinical, hemodynamic, imaging, and pathologic findings in children with pulmonary arterial hypertension (PAH) and variants in SRY-box transcription factor 17 (SOX17), a novel risk gene linked to heritable and congenital heart disease-associated PAH.
Study Design: We assembled a multi-institutional cohort of children with PAH and SOX17 variants enrolled in the Pediatric Pulmonary Hypertension Network (PPHNet) and other registries. Subjects were identified through exome and PAH gene panel sequencing.
Case report: a case of masked subclavian artery stenosis in a haemodialysis patient.

Background: Subclavian artery stenosis is generally screened by a left-right brachial systolic blood pressure difference. However, subclavian artery stenoses are often underdiagnosed due to marginally identified symptoms. In dialysis patients, a relative or absolute contradiction of measuring blood pressure in shunt brachial artery may further limit the disease screening.

A 51-year-old man, with a history of cirrhotic portal hypertension and recurrent transjugular intrahepatic portosystemic shunt (TIPS) stenoses, presented with an acute gastro-esophageal variceal hemorrhage in the setting of an acute and massive thrombotic TIPS shunt occlusion. The clinical presentation was complicated by patient's severe, chronic thrombocytopenia which had precluded empiric anticoagulation previously for recurrent TIPS dysfunction. Following endoscopic treatment of the variceal bleeding, the CAT 12 Indigo aspiration system (Penumbra) was used to remove a large burden of thrombus from the TIPS, allowing successful re-stenting and restoration of blood flow through the TIPS.
