Embolization is a way of therapeutically cutting off a supply of blood to a particular part of the body. This procedure can be used to prevent internal bleeding, stop the flow of blood to a tumor, treatment of aneurysms or to resolve abnormal connections between veins and arteries. Embolization is a less invasive way to address blood flow concerns than open surgery.
The benefits of embolization include:
- Less Complications – Given that this is a less invasive procedure than open surgery the risk factors are reduced for patients.
- No Surgical Incision – This procedure only requires a nick in the skin to insert the catheter and therefore no stitches are required.
- Brief Hospital Stay – Most people need to stay in the hospital only the night after the procedure. Normal activities can usually begin in approximately one week.
- Options When Surgery is Not Recommended – This method can be used to treat tumors and other vascular issues that can’t be removed surgically or would pose too great of a risk if surgery was attempted.
The procedure is done with the aid of x-ray imaging and a contract material so the blood vessel can be seen clearly. The doctor inserts a catheter into the blood vessel and moves it up to the area that needs to be treated. The catheter is a long, thin plastic tube that fits inside the vein or artery, it is approximately 1/8 inch in diameter so you can compare it to being smaller than a pencil lead used in a mechanical pencil. Once the catheter is positioned properly an embolic agent is inserted through the catheter and this synthetic material or medication is placed for the treatment.
Different types of embolic agents can be used depending on the size of the blood vessel and whether the agent need to be a permanent or temporary solution.
Embolization can provide treatment for a variety of medical needs, so discuss your particular situation with the doctor and they can answer your questions about the benefits and risks of their recommended course of treatment.
