Aortic Dissection
Aortic dissection is a tear within the layers of the aortic wall that allows blood to flow between them. It is classified by the Stanford system into Type A and Type B, and management depends on type, complications and clinical evaluation.
What is aortic dissection?
In aortic dissection, a tear in the inner aortic wall creates a false channel (false lumen). It can be a serious, time-critical condition that is assessed and managed urgently by the treating team; this page is educational only.
Types of aortic dissection (Stanford and DeBakey)
Aortic dissection is classified to guide treatment. The Stanford system uses Type A (involving the ascending aorta, usually managed surgically) and Type B (beyond the left subclavian artery, often managed medically, with TEVAR in complicated cases). The older DeBakey system uses Types I, II and III based on where the tear starts and how far it extends. The type — together with any complications — guides whether surgery, medical therapy or TEVAR is considered.
The role of TEVAR
In complicated Stanford Type B dissection with suitable anatomy, TEVAR may be considered to cover the entry tear and support flow through the true lumen. The decision rests with the treating physician.
How Korvia supports dissection cases
Korvia supports aortic teams with TEVAR-capable stent-graft platforms — including Percutek Tycheseal — together with case planning, device sizing, procedural readiness and on-site clinical support in Türkiye.
Frequently asked questions
What are the types of aortic dissection?+
Aortic dissection is most often classified by the Stanford system into Type A (ascending aorta) and Type B (descending aorta), and by the older DeBakey system into Types I, II and III based on where the tear starts and how far it extends. The type guides whether surgery, medical therapy or TEVAR is considered.
When are endovascular methods used in aortic dissection?+
Particularly in complicated Stanford Type B dissection, TEVAR may be considered in suitable anatomy and with physician evaluation.
What is TEVAR?+
TEVAR treats thoracic aortic disease, such as aneurysm and dissection, with an endovascular stent graft. The indication is determined by clinical evaluation.
What is the difference between EVAR and TEVAR?+
EVAR targets the abdominal aorta, while TEVAR targets the thoracic aorta. Device selection depends on the anatomical region and clinical context.
