The new operation of abdominal aortic aneurysm with fenestration stent has good effect

Mr. Chen, 60, accidentally discovered a 6.2 cm abdominal aortic aneurysm in the hospital. The location of the aneurysm covers two renal arteries. Although the traditional stent can isolate the aneurysm without rupture, it will also cover the renal artery at the expense of its blood supply, leading to renal ischemia and renal failure, and finally the kidney must be washed. After careful evaluation by the cardiovascular surgery team of Taipei Rong General Hospital, it is considered that the patient can implement a new type of fenestration stent, which not only successfully treated the aneurysm of the patient, but also preserved the renal artery blood flow and sound renal function. The patient has been discharged successfully.

At present, the mainstream treatment of abdominal aortic aneurysm is to remove this annoying tumor through minimally invasive vascular stent surgery. (Photo/taken from Taipei Veterans General Hospital) Rola Chen, a cardiac surgeon at Taipei Veterans General Hospital, said that abdominal aortic aneurysm is like an untimely bomb. Traditional surgical treatment is often frightening because of the large wound. At present, the mainstream of treatment is to remove this trouble with minimally invasive vascular stent surgery. This kind of operation has flourished in recent ten years. Up to now, large-scale reports have confirmed that minimally invasive stent surgery for abdominal aortic aneurysm has satisfactory success rate and survival rate. Taipei Rong General Hospital successfully treated more than 500 cases of aortic aneurysm with minimally invasive stent surgery, accounting for 90% of all aortic aneurysm cases.

In the treatment of abdominal aortic aneurysm, if the scope of the aneurysm covers important branches, such as renal artery, superior mesenteric artery, internal iliac artery and so on. It often increases the complexity and difficulty of the operation. A few patients can't even achieve the purpose of treatment with minimally invasive vascular stent surgery, but need to remove the aneurysm with traditional highly invasive surgery.

Due to the rapid development of medical technology, in the face of this complex abdominal aortic aneurysm, the existing fenestration or bifurcation stent is specially designed to treat this abdominal aortic aneurysm covering important branches, which can not only achieve the therapeutic purpose of avoiding aneurysm rupture, but also preserve important vascular branches, avoid ischemia of important organs and preserve their functions, with a success rate of 100%. But at present, this kind of stent health insurance is not paid, and it is a self-funded project. If the future medical insurance bureau can fully cover it, it will benefit more patients.
