EVAR — Endovascular Aneurysm Repair
EVAR (endovascular aneurysm repair) is a minimally invasive way to treat an abdominal aortic aneurysm — a balloon-like widening of the body's main artery in the abdomen — from inside the vessels, usually without opening the abdomen. This page explains EVAR in plain language: what EVAR is, why it emerged as an alternative to open surgery, who EVAR may suit, and why a good result depends on the right physician, the right product and the right procedure. Suitability for EVAR is always decided by the treating physician.
What is EVAR, in plain terms?
The aorta is the largest artery, carrying blood from the heart to the body. When the wall of its abdominal section weakens and bulges, this is an abdominal aortic aneurysm. EVAR supports that weakened area from the inside with a stent graft — a fabric-covered metal 'sleeve' — so blood pressure no longer pushes directly on the fragile wall. In an EVAR procedure the device is guided to the aneurysm through a thin tube from the groin, so a large abdominal incision is usually not needed. EVAR is used in appropriate patients and according to the manufacturer's instructions for use.
Why move from open surgery to a minimally invasive method like EVAR?
In traditional open surgery the abdomen is opened and the widened aortic segment is replaced with a graft — effective, but a major operation with a longer recovery. EVAR is performed from inside the vessels, so in suitable cases it can mean a smaller incision, a shorter hospital stay and a faster recovery. That is why, for many patients with suitable anatomy, EVAR has become an increasingly common option. EVAR is not right for everyone and requires regular imaging follow-up; the choice between open surgery, EVAR and surveillance rests entirely with the treating physician.
Who might EVAR be suitable for?
EVAR is considered when the aneurysm's location, size and vessel anatomy are suitable — for example an adequate proximal 'neck' and access vessels. The aneurysm's diameter, its growth rate and the patient's overall health guide whether EVAR, open surgery or watchful follow-up is the right path. This decision comes from the physician's detailed imaging and clinical evaluation; this page is educational only.
The right physician, the right product, the right procedure
The success of EVAR depends not on one thing but on the whole picture: the right physician (an experienced team selecting the right patient and planning the case), the right product (a reliable, correctly sized EVAR stent graft matched to the patient's anatomy) and the right procedure (careful preparation and technique). When these three come together, the benefit expected from EVAR is greatest. A mismatch — for example a device that does not fit the anatomy — can affect the outcome, which is why EVAR sizing and planning are so important.
Korvia's role: the right EVAR device, ready at the right time
A physician can choose the right patient and the right procedure — but that is not enough if the right product is not available and suited to the patient at that moment. This is exactly where Korvia comes in: Korvia brings EVAR-capable aortic stent-graft platforms (including Percutek Tycheseal) to Türkiye, supports the physician with EVAR device sizing and case planning, maintains on-site clinical presence, and keeps product availability continuous. So the physician can trust the 'right product, right size, right time' equation and focus on what matters most — the patient. For Korvia, EVAR is not just a device; it is a treatment ecosystem where the right product meets the right physician and the right procedure.
After EVAR: why follow-up matters
After EVAR, regular imaging follow-up checks that the stent graft stays in the right position and that the aneurysm sac is no longer under pressure. Sometimes blood can still leak into the sac (an endoleak); most of these are simply monitored, while some may need further treatment. Continuity of follow-up — and of the device and support behind it — is part of the same 'right product, right support' chain that Korvia helps keep unbroken in Türkiye.
Frequently asked questions
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.
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.
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 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 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.
How does Korvia provide clinical support to physicians?+
Through case planning, device sizing, procedural readiness and on-site clinical support alongside the physician.
