What is EVAR?+
EVAR is the minimally invasive repair of an abdominal aortic aneurysm using a stent graft delivered through the vessels. Suitability depends on anatomical evaluation and physician judgement.
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.
What is endovascular aortic repair?+
Repair of the aorta from inside the vessel with a stent graft — a minimally invasive alternative to open surgery in suitable patients.
What is a stent graft?+
A stent graft is an endovascular device, a metal frame with a fabric cover, that supports a diseased aortic segment from within.
What is an aortic stent?+
An aortic stent / stent graft is designed to support the aortic lumen and re-establish blood flow; use is subject to manufacturer instructions for use.
How is an abdominal aortic aneurysm treated?+
Depending on size, anatomy and patient status, management may include surveillance, open surgery or endovascular methods such as EVAR. The decision rests with the physician.
How is a thoracic aortic aneurysm treated?+
In suitable cases, endovascular methods such as TEVAR or open surgery may be considered; selection depends on anatomical and clinical evaluation.
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 FEVAR?+
FEVAR is an EVAR technique for complex anatomy that uses a fenestrated stent graft to preserve renal and visceral branch vessels.
What is BEVAR?+
BEVAR uses a branched stent graft to perfuse side branches in thoracoabdominal anatomy; it is used in selected cases.
What is the fenestration technique?+
An approach for complex aortic anatomy where openings (fenestrations) in the stent graft keep branch vessels patent.
What is a branched stent graft?+
A stent graft with integrated side branches, designed to preserve branch vessels in thoracoabdominal and complex aortic anatomy.
What is Chimney EVAR?+
The chimney technique places parallel stents alongside the main stent graft to preserve branch vessels, used in appropriate cases.
What is an endoleak?+
An endoleak is persistent blood flow into the aneurysm sac after stent graft placement. Depending on its type it may require surveillance or further intervention, as assessed by the physician.
What areas does Korvia work in?+
Korvia provides solutions across cardiovascular, endovascular, aortic, peripheral vascular, interventional radiology and interventional cardiology.
How does Korvia provide clinical support to physicians?+
Through case planning, device sizing, procedural readiness and on-site clinical support alongside the physician.
Why should manufacturers work with Korvia in Türkiye?+
Korvia is a long-term, reliable Türkiye partner combining clinical discipline, field execution, market access and regulatory readiness.
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.
What is the difference between AAA and TAA?+
The difference is location: an abdominal aortic aneurysm (AAA) is in the abdominal aorta, while a thoracic aortic aneurysm (TAA) is in the chest. AAA is often treated with EVAR and TAA with TEVAR, depending on anatomy and physician evaluation.
