[Ascending Aorta and Aortic Arch - Endovascular Therapy Today and in the Future]

Pathologies in the region of the aortic arch may occur in isolation, but adjacent segments of the thoracic aorta - the ascending or descending aorta - are much more commonly affected. The first surgical procedures to treat the aortic arch were performed nearly six decades ago. Despite numerous improvements and innovations in the 20th and early 21st centuries, these procedures are still associated with relevant operative mortality and neurological complication rates. Endovascular techniques and modern hybrid procedures are increasingly expanding the therapeutic spectrum in the aortic arch, although the open surgical approach is currently still the gold standard. Endovascular treatment of aortic aneurysm was first performed in the early 1990s in the infrarenal abdominal aorta. It was not long before the first attempts at endovascular therapy were made for the treatment of the aortic arch. In 1996, Inoue et al. reported the use of the first commonly used endoprosthesis to treat aneurysms in the aortic arch. Continuous improvements and refinements in implantation techniques and also implanted material have resulted in endovascular therapy now being an increasingly important option compared to open surgical procedures in the descending thoracic and abdominal aorta and has partially replaced them as the gold standard. This review article aims to provide an overview of the prerequisites, results, but also limitations of endovascular surgery of the aortic arch.
