At present, the Department of Interventional Therapy of Guangdong Provincial People’s Hospital carries out minimally invasive interventional treatment of solid tumors of various systems of the body and interventional treatment of peripheral vascular diseases, deep vein thrombosis, varicose veins, herniated discs, liver and kidney swelling and other benign diseases. In particular, he has done many successful cases in tumor interventional treatment. Mr. Li, who loves traveling and sports, usually has intermittent abdominal pain, but did not pay enough attention to it. four months ago, he felt a swelling in the left lower abdomen when taking a bath, and went to the local hospital for examination, and the CT results showed that it was an abdominal aortic aneurysm with a maximum dimension of 9×10 cm. Mr. Li has a history of hypertension and takes antihypertensive drugs regularly. When the doctor told him: patients with abdominal aortic aneurysm should not exercise strenuously, strenuous exercise may lead to aneurysm rupture, especially for hypertensive patients, once the aneurysm rupture occurs, it can be life-threatening. This news was like a bolt from the blue for Mr. Li, who loves sports. Mr. Li went to all the major hospitals in Guangzhou, but he did not get a clear treatment plan. When he learned from the Internet that our interventional department had successfully treated several cases of abdominal aortic aneurysm, Mr. Li came to our department. After being admitted to the hospital and completing the relevant examinations, Lu Ligong, the director of the interventional department, immediately organized a consultation with the whole department and requested consultations with related departments such as the vascular thyroid abdominal wall hernia surgery and the anesthesiology department. Director Lu Ligong and the consulting physicians offered two sets of treatment options: surgery or interventional treatment. Considering the higher risk of surgery, the patient and his family decided on interventional treatment. At around 9:00 a.m., the patient was admitted to the interventional room. General anesthesia, angiotomy, and placement of a contrast catheter were performed, and the results made everyone gasp. The angiogram showed a huge tumor-like dilatation below the bilateral renal arteries. Such a huge hemangioma was at risk of rupture at any time. Director Lu Ligong led his assistant to operate carefully, searching for the vessels one at a time and imaging them one at a time. One at a time, he rotated the bulb one at a time, because the placement of stent is a delicate job, and incorrect position may isolate the renal artery and cause serious consequences. The ideal position for release was finally found. The postoperative angiogram showed that the aneurysm had been isolated by the stent throughout, with no lateral leakage or extravasation, and the stent was well attached to the wall, which brought a smile of satisfaction to the face of Director Lu Ligong and made the operation a success. After the operation, under the careful care of ICU and our department, Mr. Li soon recovered and was discharged from the hospital. On the day of discharge, he sent a beautiful flower basket to our department and said gratefully, “Thanks to Director Lu and all the medical staff of the interventional department, I can go to see the great country again.” Abdominal aortic aneurysm (AAA) is a common life-threatening degenerative arterial lesion, ranking 10th among the causes of death in men over 65 years of age. Studies have shown that its incidence is closely related to age, with an incidence of 25. 6 per 100,000 men over the age of 50 and 78. 3 per 100,000 men over the age of 70 in Asia, with the incidence in men being about 3. 5 times higher than in women. Most pre-existing abdominal aortic aneurysms are asymptomatic and difficult to detect on physical examination. Smoking, hypertension, family history of abdominal aortic aneurysm, and older men are all high risk factors for AAA. The traditional treatment for abdominal aortic aneurysms is surgical resection. The timing of surgery is extremely important, and studies have shown that the incidence of rupture of abdominal aortic aneurysms with a diameter of 5.5 to 6.0 cm within one year is 9%, that of 6.9 to 7.0 cm is 10%, and that of 7.0 cm or more is 33%. 90%. The ultimate goal of surgical treatment is to prevent rupture of the aneurysm. Surgery is generally considered for asymptomatic abdominal aortic aneurysms that are more than 5.5 cm in diameter or that increase in diameter by 0.6 to 0.8 cm per year, while more aggressive surgical management is required for patients with symptoms (back, abdominal, groin, testicular, leg pain, etc.). Parod performed the first endoluminal abdominal aortic aneurysm surgery using an artificial vascular stent in 1991, which received widespread attention and rapidly gained universal adoption. The currently accepted indications for EVAR are: ① A sufficient non-dilated zone between the distal abdominal aorta and the renal artery to allow proximal anchoring of the endovascular graft, i.e., the proximal aneurysm neck. The length of the proximal normal abdominal aorta needs to be determined by the characteristics of each graft, and the recommended length is 1. 0 to 1. 5 cm. ② Severe distortion of the proximal aneurysmal neck will not allow for endovascular intervention. In general, if the angle above the renal artery to the proximal tubercle is < 60°, the manufacturer will not recommend intervention despite the final decision of the maximum angle acceptable for the particular stent. ③If the site to be stented is the iliac artery, it must be morphologically adequate for endovascular device attachment. ④The caliber of the common and external iliac arteries must allow passage of the delivery sheath, or they must withstand balloon expansion to facilitate passage of the delivery sheath. ⑤ The degree of tortuosity of the iliac vessels must allow access of the delivery system to the abdominal aorta, and differences in the compliance and deployment of the delivery system of stent grafts may affect their eventual use in tortuous vessels. (6) The malformed vessel, especially the necessary submesenteric or collateral renal arteries, cannot be located in the segment of the abdominal aorta that needs to be excluded, and if these criteria are not met, it is possible that the intervention cannot be performed for technical reasons. Since the first EVAR was performed, endoluminal vascular techniques have progressed at a rapid pace. With increased operator experience, improved grafts, and related technical improvements, more and more patients will enjoy the convenience of endoluminal techniques. At the same time, as more randomized controlled trials and systematic reviews are completed, the results will more accurately and reliably guide clinicians in their clinical decisions.
