Arterial Access Site Complications after Percutaneous Interventions with Special Regard to the Application of Vascular Closure Devices

Due to an increase in the number of performed endovascular procedures, the number of local access site complications is rising too. Used mainly for treatment of peripheral arterial disease and coronary heart disease, endovascular procedures are gaining importance. Access site complications include bleeding, haematoma, pseudoaneurysm, arteriovenous fistula and arterial thrombosis. Aiming to reduce immobilisation, length of hospital stay, costs and access site complications, vascular closure devices (VCD) were introduced in the mid 1990s, but current trials failed to demonstrate the superiority of these devices compared to conventional manual compression if it comes to access site complications. We retrospectively evaluated all patients who were treated surgically due to access site complications between 2001 and 2012 in our institution. In total, 522 patients needed vascular surgery to treat different access site complications. During this period, 90,538 percutaneous interventions were performed in our institution, leading to a total incidence of 0.58% of access site complications. Depending on the frequency of application of VCDs, patients have been grouped in groups A-C. With the more frequent use of VCDs, the incidence of access site complications increased and, in particular, ischaemic complications were seen more often. In conclusion, the application of VCDs to prevent access site complications is questionable and not justified when looking at published data.
