The interventional therapy is a 90 minutes procedure performed in local anesthesia. This procedure could guide a large quantity of stem cells into the target area.
In the beginning of the procedure, the area of catheterization needs to be sterilized. Then the doctor will apply local anesthetics.
A needle will be passed into the main artery, and a guide wire will be inserted through this needle. Then the needle will be removed. The catheter is guided exactly to the target area.
In order to show the area on the CT images, a radio-opaque contrast material will be injected into the blood vessel through this catheter. When absorbing the x-rays, the contrast agent will become visible, and then the inside of blood vessels is visualized for doctors to check if the catheter has reached the pancreatic artery as planned.
Stem cells are injected as long as the position is confirmed by angiogram.
At last, the catheter will be removed, and the patient needs to be observed for overnight.
Possible risks and complications
It is very rare for patients to have major complications after this interventional therapy. However, it is possible to have side-effects as bleeding, bruising at the puncture side, blood vessel damage, and allergic reaction to the contrast material.
