Zusammenfassung
Die evidenzbasierte leitliniengerechte antithrombotische Therapie von Patient:innen mit peripherer arterieller Verschlusskrankheit (PAVK) stellt seit langer Zeit eine Herausforderung im klinischen Alltag von Gefäßmediziner:innen dar. Erstmals wird 2023 eine Praxisleitlinie der European Society for Vascular Surgery (ESVS) erwartet, die sich explizit mit der antithrombotischen Therapie von Patient:innen mit Gefäßkrankheiten befasst. Viele Entscheidungen und Leitlinienempfehlungen wurden bisher auf dem Boden von Studien aus anderen Fachbereichen generiert, da keine geeignete hochwertige Evidenzbasis existiert. In den vergangenen Jahren sind innovative Studiendaten veröffentlicht worden, die neue Erkenntnisse, aber auch neue Herausforderungen eingeführt haben. Dieser Artikel gibt eine Übersicht über die derzeitige Studienlage und deren Praxisrelevanz. Speziell wird dabei auf die unterschiedlichen Behandlungsoptionen (konservativ, endovaskulär, offen-chirurgisch) und die diffizile Abwägung von Wirksamkeit gegen Sicherheit eingegangen. Die für und wider von Kombinationsendpunkten aktueller Studien werden ebenso diskutiert, wie der immanente Selektionsbias und das Risiko für schwere Blutungen. Gleichzeitig soll aber auch die derzeitige Versorgungsrealität einschließlich der Verschreibungspraxis dargestellt werden.
Abstract
The evidence-based guideline-compliant antithrombotic treatment of patients with peripheral arterial occlusive disease (PAOD) has for a long time been a challenge in the routine clinical practice of vascular specialists. For the first time in 2023 clinical practice guidelines of the European Society for Vascular Surgery (ESVS) that explicitly deal with the antithrombotic treatment of patients with vascular diseases are expected. Many decisions and guideline recommendations have been based on studies from other medical specialties as no suitable evidence base exists. Most recently, innovative studies were published that introduced more knowledge but also new challenges for healthcare professionals. This article provides an overview of the current study situation and its relevance in clinical practice. Thereby, it explicitly discusses the different treatment options (conservative, endovascular, open surgery) and the difficult balance between efficacy and safety of antithrombotic drugs. The advantages and disadvantages of composite endpoints of current studies as well as the inherent selection bias and risk for major bleeding events are meticulously discussed. Simultaneously, the current treatment reality including the prescription practice is also presented.
