Juxta-anastomotic stenosis in the forearm native arteriovenous fistula: Open surgery or angioplasty?

Background: The juxta-anastomotic stenosis (JAS) represents the major complication of arteriovenous fistula (AVF) during the first months after the surgery and the approach to JAS can be surgical or radiological.

Methods: From 01/02/2016 to 31/12/2020, a total of 976 radiocephalic fistulas have been performed. The 15.

[Case Report: MPO-ANCA Associated Vasculitis After Pfizer-BioNTech COVID-19 mRNA Vaccination].

We report a case of MPO-anti-neutrophil cytoplasmic antibody ANCA-associated vasculitis, with pulmonary-renal syndrome, after the mRNA booster third dose vaccine Pfizer BioNTech against COVID-19 in 71-year-old Caucasian man with no specific past medical history. A kidney biopsy diagnosed ANCA-associated pauci-immune crescentic glomerulonephritis. Renal function and constitutional symptoms have been partially improved with treatment with dialysis, intravenous rituximab and steroid pulse therapy.

[IgA nephropathy and granulomatosis with polyangiitis-overlap: a rare coexistence of two glomerular nephropathies with remission after steroids and rituximab].

Granulomatosis with polyangiitis (GPA) is an ANCA-positive systemic vasculitis that mainly involves lungs and kidneys. This condition rarely overlaps with other glomerulonephritides. A 42-year-old man with constitutional symptoms and haemophtoe was admitted to the Infectious Diseases department, where he was subjected to fibrobronchoscopy with BAL (broncho-alveolar lavage) and lung transbronchial biopsy that showed histological signs of vasculitis.

Hemodynamic impact of VASQ device in vascular access creation.

Background: Native arteriovenous fistula is the preferred vascular access in term of functionality, efficiency and complication rate. Nevertheless, research continues to seek strategies to reduce the risk of neointimal hyperplasia and hemodynamic modification. The aim of the study was to evaluate the impact on hemodynamic of the VasQ device in arteriovenous fistulae creation.
