Percutaneous treatment of vascular access-site complications: a ten years' experience in two centres

The spread of percutaneous arterial catheterization in diagnostic and therapeutic procedures has led to a parallel increase of vascular access site complications. The incidence of these events is between 0.2-1%. A detailed analysis of injuries by type of procedure shows a higher incidence of injuries after therapeutic procedures (3%) than those observed for diagnostic ones (1%), due to the greater size of the vascular devices used and the necessity to frequently administer anticoagulant and antiplatelet therapy during procedures. The iatrogenic arterial injuries requiring treatment are the pseudoaneurysm, arteriovenous fistula, arterial rupture and dissection. Less frequent complications include distal embolization of the limbs, nerve damage, abscess and lymphocele. Moreover, the use of percutaneous vascular closure devices (VCD) has further expanded the types of complications, with an increased risk of stenosis, thrombosis, distal embolism and infection. Our work aims to bring the personal 10 years' experience in the percutaneous treatment of vascular access-site complications.
