Complicanze Tardive Non Comuni Della Venipuntura a Siti Costanti ( Buttonhole Technique,BH): Descrizione Di Due Casi Clinici

The venipuncture at fixed sites, known as buttonhole (BH), is an alternative cannulation technique of arteriovenous fistulae (AVF). The BH technique is becoming more and more common, and finds a favourable response among patients who describe it as less painful. Complications inherent with this type of cannulation are not more than the classic venipuncture at variable sites, with the exception of a higher incidence of sepsis. We here describe two clinical cases; of these, we highlight another type of local complication of which pathogenesis and clinical relevance could be correlated with the dysfunction of vascular access and sepsis.
