Zusammenfassung

Background: The quality of vascular care has significantly improved in part by the expansion of endovascular techniques for the treatment of symptomatic peripheral artery disease (PAD) in recent years. In Germany these are primarily provided by the three disciplines of vascular surgery, angiology, and interventional radiology (IR). However, the relative contribute of angiologists to the total number of cases performed is unknown. Patients and methods: In the present study, we analysed the respective contribution of vascular surgery, angiology, and IR to the delivery of endovascular revascularisations in symptomatic PAD in Germany based on the legally mandatory quality reports representative for the reporting year 2018. Results: Vascular surgery is the most common speciality reporting procedures in German hospitals (n=579; 25.1%), followed by IR (n=264; 11.5%), angiology (n=189; 8.2%) and cardiology (n=17; 0.7%). The combination of vascular surgery and IR was reported in 202 (8.8%), vascular surgery and angiology in 167 (7.2%) and angiology and IR in 65 (2.8%) hospitals, and 63 (2.7%) hospitals reported the combination of all three disciplines. Not every department performed catheter interventions. The analysis of procedures per centre revealed that angiology centres provided the highest numbers for both basic procedures and more complex techniques such as atherectomy, rotational thrombectomy, lithoplasty, selective thrombolysis or the use of re-entry devices. In total, angiology centres provided 24.4% of the total procedures or 23.9% of the so-called basic procedures as a surrogate for patient numbers. Conclusions: While each of the disciplines contribute significantly to the endovascular procedures, angiology centres perform more procedures per centre and more complex procedures than the other disciplines highlighting the important quantitative and qualitative contribution of angiology specialists to the care of vascular patients. The inpatient catheter interventional care of patients with PAD is still too rarely carried out in a multi-disciplinary manner in Germany.
