What is an Endovascular Aneurysm Repair?
An endovascular stent graft repair is a treatment for aneurysms of the descending (thoracic and abdominal) aorta. It is similar to the approach used for a cardiac catheterization of the coronary arteries. This procedure requires only small incisions in the groin. Then the surgeon inserts a catheter through the femoral artery in the groin and with the use of x-ray guidance and specially-designed instruments, the aneurysm can be treated from inside the aorta by inserting a tube, called a stent-graft.
The tube, or stent graft, is delivered through the catheter in a collapsed state and then expanded at the site of the aneurysm. The tube replaces and reinforces the diseased aortic wall, ensuring continuity of blood flow while preventing further expansion of the aorta, aortic rupture, and/or aortic dissection.
The potential benefits of the procedure include greatly reduced risk, a shorter hospital stay, and a more rapid recovery.
What is an Hybrid Aortic Procedure?
Not all aneurysms can be repaired by means of an endovascular stent graft alone. Hybrid procedures use endovascular stenting along with open surgery to take advantage of the benefits of both while minimizing the limitations and related risks of using either alone. Often, hybrid procedures can be custom designed for the patient in an effort to decrease size of the incision, duration of the procedure, and avoid the need to stop blood flow to the heart and/or brain. This is intended to improve recovery and ensure the best possible outcome for the patient.
