Endovascular Therapy for Acute Type B Aortic Dissection

Type B acute aortic dissection (TBAAD) is a severe condition that requires urgent intervention to minimize complications and improve outcomes. Endovascular treatment has emerged as an effective approach for managing this challenging condition in acute complicated type B dissections or in case of high-risk features for later adverse event. This involves placing stent grafts to seal the tear, redirect blood flow, and promote clot formation. Endovascular treatment reduces mortality and complication rates, allowing for a faster recovery. The benefits of endovascular repair in complicated TBAAD have been extensively demonstrated, showing lower morbidity and in-hospital mortality (5%-8% vs 15%-30%) rates compared to traditional open surgery. This technique offers better control over the extent of the dissection, leading to improved patient outcomes and shorter hospital stays. It is essential to optimize antihypertensive therapy and provide proper patients education. Regular angio-CT scans should be done to monitor disease progression and ensure long-term success. Endovascular treatment has revolutionized the management of TBAAD by providing a less invasive, more effective approach, enhancing patient care and prognosis.
