Sharp Needle Recanalization: A Salvage Procedure for Failing Arteriovenous Fistula Due to Tight Uncrossable Venous Stenosis

[摘要] A 33-year- old male presented with malfunctioning brachiobasilic arteriovenous fistula (AVF) due to short tightjuxta anastomotic stenosis (►Fig. 1). Access was gainedinto the AVF draining vein, and multiple trials to cross the chiobasilic arteriovenous fistula (AVF) due to short tightjuxta anastomotic stenosis (►Fig. 1). Access was gainedinto the AVF draining vein, and multiple trials to cross thetight stenosis using catheter and wire failed (►Fig. 2).Sharp needle recanalization was performed under ultrasound guidance, using 21G needle and wire to cross thistight stenosis (►Fig. 3a,b).
