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.
Stanford Type A and Type B
Type A involves the ascending aorta and is typically managed surgically. Type B involves the descending aorta beyond the left subclavian artery and is often managed medically, with intervention reserved for complicated cases.
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
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.
