Endovascular repair for acute aortic syndrome involving the descending aorta

Abstract

This review paper delves into the acute aortic syndromes, with a particular focus on those affecting the descending thoracic aorta, including acute type B aortic dissection (aTBAD), intramural hematoma (IMH), penetrating aortic ulcer (PAU), blunt traumatic thoracic aortic injury (bTAI), and ruptured aneurysm of the descending thoracic aorta (rDTA). These conditions present with sudden-onset symptoms such as severe chest or back pain, necessitating immediate medical attention. While traditional open surgical repair was historically the mainstay of treatment, advancements in endovascular techniques have revolutionized management approaches. Endovascular treatment offers advantages such as reduced operative time, blood loss, and hospital stay, making it a safer option for high-risk patients. However, it is crucial to carefully evaluate patients for endovascular suitability, considering the potential complications and risks associated with these techniques. This paper aims to provide an updated overview of acute aortic syndromes involving the descending thoracic aorta, analyze available therapeutic options, and review contemporary treatment modalities, shedding light on the technical aspects and considerations guiding clinical decision-making in this complex and life-threatening scenario.
