What is an Endovascular Aneurysm Repair (EVAR)?

Endovascular Aneurysm Repair (EVAR) is a modern, minimally invasive procedure used to treat an aortic aneurysm, which is a weakened and enlarged area in the wall of the aorta, the body’s main blood vessel. If an aneurysm grows too large, it can rupture and cause serious internal bleeding.
In an EVAR procedure, doctors make small incisions in the groin and insert a special fabric-covered metal tube called a stent graft into the blood vessels. Using advanced imaging guidance, the stent graft is carefully positioned inside the aorta at the site of the aneurysm. Once in place, it creates a new channel for blood flow, reducing pressure on the weakened portion of the artery and lowering the risk of rupture.
Because EVAR is performed through small incisions rather than a large surgical opening, patients generally experience less pain, less blood loss, and a quicker recovery. Most people can return to their normal activities sooner compared to traditional open aneurysm surgery.
EVAR is not suitable for every patient, and the decision to perform the procedure depends on the size, location, and shape of the aneurysm, as well as the patient’s overall health. After treatment, regular follow-up scans are important to ensure the stent graft remains in the correct position and continues to protect the aorta effectively.

Types of Endovascular Aneurysm Repair (EVAR):

The type of Endovascular Aneurysm Repair (EVAR) performed depends on the aneurysm’s location and the structure of the patient’s blood vessels. Advances in endovascular technology have made it possible to treat both straightforward and highly complex aneurysms using minimally invasive techniques.
Standard EVAR: Standard EVAR is the most commonly used procedure for treating abdominal aortic aneurysms located below the arteries that supply the kidneys. A stent graft is placed inside the aorta to strengthen the weakened area and create a new pathway for blood flow, reducing the risk of aneurysm rupture.
Fenestrated EVAR (FEVAR): Fenestrated EVAR is designed for aneurysms that are close to important arteries supplying organs such as the kidneys or intestines. The stent graft used in this procedure contains specially created openings that allow blood to continue flowing to these arteries while effectively treating the aneurysm.
Branched EVAR (BEVAR): Branched EVAR is used for more complex aneurysms that involve major branches of the aorta. The stent graft includes built-in side branches that help maintain blood supply to vital organs while excluding the aneurysm from circulation.
Thoracic Endovascular Aortic Repair (TEVAR): TEVAR is a specialised form of endovascular repair used to treat aneurysms and other conditions affecting the thoracic aorta, the section of the aorta located in the chest. The procedure strengthens the diseased portion of the vessel and helps prevent potentially life-threatening complications.
Complex Endovascular Aortic Repair: Some aneurysms have challenging anatomy and require customised treatment strategies. Complex endovascular repair may involve advanced stent graft designs and specialised techniques to manage aneurysms that extend across multiple sections of the aorta or involve critical blood vessels.

Every aneurysm is different, and the most appropriate treatment depends on several factors, including the aneurysm’s size and location, the condition of the aorta, and the patient’s overall health. Detailed imaging studies help specialists determine the most suitable approach, ensuring safe treatment and the best possible long-term outcome.
