Distal AVF creation with marginal calcified radial artery: Multicentric experience of intraoperative intravascular lithotripsy.

Introduction: The first-choice vascular access to starting dialysis in patients with End Stage Renal Disease (ESRD) is autogenous distal arteriovenous-fistula (AVF) to spare vascular district avoiding proximal fistula complications. One of most significant exclusion criteria to create distal AVF is still now the presence of huge calcification of the feeding artery due to large numbers of early failure (EF) and failure in maturation (FTM). In recent years the possibility to use new devices able to deliver intravascular lithotripsy (IVL) to treat high calcified stenosis could be a possibility to recruit these marginal arteries to create distal AVF.

Continuous venovenous hemofiltration after coronary procedures for the prevention of contrast-induced acute kidney injury in patients with severe chronic renal failure.

Continuous venovenous hemofiltration (CVVH) is a renal replacement therapy that has been successfully used in patients with severe chronic renal failure to prevent contrast-induced acute kidney injury (CI-AKI). In this study, we present a consecutive experience using a new CVVH protocol that has also been applied to patients with acute coronary syndrome (ACS). CVVH was performed in consecutive patients with estimated glomerular filtration rate <30 ml/min/1.

[Prevention of contrast-induced acute kidney injury].

Contrast-induced nephropathy (CIN) is one of the most frequent causes of acute kidney injury in hospitalized patients. Its incidence depends on patient risk factors (chronic kidney disease, diabetes, cardiovascular diseases and older age) and procedure-related factors (high contrast dose, intraarterial administration). Chronic kidney disease, especially if associated with diabetes, is the main risk factor for CIN.
