Common complications of endoluminal isolation of the abdominal aorta include endovascular fistula and stent migration. Intracavitary isolation of the abdominal aorta refers to the introduction of a stent-type artificial blood vessel into the abdominal aorta via the femoral artery, which expands to isolate the abdominal aortic aneurysm from the vascular lumen, eliminating the potential risk of aneurysm rupture or hemorrhage and restoring smooth blood flow to the abdominal aortic aneurysm. However, there are some complications associated with this procedure, such as internal fistula, which occurs when the stent does not fit completely into the aneurysm, causing blood to flow into the aneurysm cavity through the unconfined area and causing the aneurysm to continue to grow in size. If the fistula is mild, a blood clot may form inside the aneurysm and close it; if the fistula is severe, additional stents or spring coils may be needed to block the fistula. In addition, lesions such as cerebral infarction, spinal cord ischemia, renal artery occlusion, and ischemic colitis may occur; or stent migration or infection; or systemic inflammatory reaction due to placement, which may result in postoperative syndrome after endoluminal isolation of abdominal aortic aneurysm. It is important to note that there are risks associated with any surgical procedure, and it is advisable to follow the advice of a specialist in the treatment of the disease, and not to avoid delaying the condition due to possible complications.
