Why do I Need a Mesenteric Embolization?
- You will have blood tests to check your blood clotting ability and kidney function.
- You do not need to stop eating before the procedure (unless you have surgery planned for the same day), but you must drink sufficient water.
- If you have severe kidney problems, you will be given intravenous fluids (one drip) for 6 hours, i.e. one hour before the procedure.
- Some pain relievers (non-steroidal anti-inflammatory drugs) may need to be stopped on the day of the exam for 24 hours; discuss this with the ward nurses.
- You will need to wear a hospital gown. The porters will pick you up from the room and take you to the X-ray department on your bed for the procedure
- You will be taken to the X-ray room where you will be asked to lie down on the X-ray table.
- If you are having a mesenteric embolization, a radiology nurse will monitor your blood pressure and stay with you throughout the procedure.
- The radiologist (an x-ray doctor) will inject a local anesthetic into the skin of your groin to freeze the area.
- You may still feel some pressure, but if you feel any pain during the procedure, tell the radiologist. You will be asked to lie down as still as possible.
- The catheter is then inserted into the artery in the groin and, using X-rays to assist, the radiologist moves the catheter to the correct position.
- X-rays are taken while the dye is injected through the catheter into the arteries. Sometimes the injection can cause a feeling of warmth for a while or the feeling that you have urinated.
- At this point, embolization treatment will be performed if necessary.
- When the X-rays are completed, the catheter is removed and a special sealing device is placed in the artery to seal the hole, or pressure is applied to the groin for about ten minutes to minimize any bruising.
- If you had embolization and are having surgery the same day, a small catheter called a sheath may be left in your groin as movement is restricted after removal.
Frequently Asked Questions:
It is a special X-ray of the blood vessels (arteries) in the abdomen to show where the artery is blocked or bleeding.
A decrease in blood flow can permanently damage the small intestine. Sudden loss of blood flow to the small intestine (acute mesenteric ischemia) due to a blood clot requires immediate surgery.
The mesenteric arteries take blood from the aorta and distribute it to a large part of the gastrointestinal tract. Both the superior and inferior mesenteric arteries arise from the abdominal aorta.
Computed tomography is useful in the diagnosis of superior mesenteric artery syndrome and can provide diagnostic information, including distances between the superior mesenteric artery and the aorta and duodenal distention.
Ischemia is potentially reversible if the cause can be treated and flow restored. Therefore, intestinal infarction is a surgical emergency that requires rapid diagnosis and surgical removal of the unviable intestine.
Tests used to diagnose chronic mesenteric ischemia include: Mesenteric duplex ultrasound allows your doctor to see how blood is flowing through the mesenteric arteries and if there is any blockage.
Mesenteric embolization is an established treatment for lower gastrointestinal bleeding. This study aimed to determine the outcome of angiography and embolization and their influencing factors.
