What is the interventional treatment for renal artery aneurysm?

The advantages of interventional treatment, through clinical cases, have improved the recovery rate of patients, with smaller wounds and less bleeding. These have helped patients with many types of diseases to get out of the shadow of the disease. What is the interventional treatment of renal artery aneurysm?

Renal artery aneurysms are not rare, accounting for about 19% of visceral artery aneurysms. 80% are unilateral, 17% are intrarenal, and 30% are multiple. The incidence is roughly the same for both sexes, and about 50% are diagnosed around the age of 50. Initially, it was thought that the incidence was extremely low, until the application of selective renal artery angiography revealed that it was not uncommon. The incidence is currently believed to be 0.1% to 0.3%.

The traditional treatment for renal artery aneurysm is surgery. The principle of traditional surgical treatment is to remove the aneurysm and maintain normal renal function. Methods include renal artery aneurysm resection combined with in situ repair, autologous vein or artificial blood vessel interposition transplantation or bypass; ex vivo hypothermic perfusion, renal artery aneurysm resection and repair, autologous kidney transplantation, etc.

In today's medical community, the treatment of renal artery aneurysms generally adopts minimally invasive interventional therapy, which is also a comprehensive treatment method for various cancers, and this technology is becoming more and more mature. Next, let's take a look at the process of interventional therapy for renal artery aneurysms.

1. Interventional therapy only requires a small incision to insert a thin tube into the blood vessel.

2. The characteristics of interventional therapy are: ① less damage, safe and easy; ② accurate positioning, rapid and certain therapeutic effect; ③ few side effects and complications.

3. The method of use is: usually at the base of the thigh, puncture the skin, insert a special catheter into the femoral artery, and then insert it into the abdomen.

4. Its main value lies in: 1. It can reduce the tumor mass, making liver cancer that was originally unresectable become resectable, or create conditions for other treatments such as argon-helium cryosurgery; 2. After liver cancer resection or cryosurgery, this method helps prevent recurrence.

In recent years, interventional therapy has partially replaced surgical methods and become the first choice for renal artery aneurysm due to its characteristics of less trauma, significant effect, simplicity and safety. The methods include aneurysm embolization and intraluminal isolation of covered stents.
