Gastrointestinal bleeding is a serious medical emergency, if not diagnosed and treated promptly, it can affect the patient's life. For cases of gastrointestinal bleeding that are not caused by varicose veins that are not indicated for medical or endoscopic treatment, the method of angiography and intervention of the lower mesenteric vessels with enhanced x-ray is the choice. choose optimal.
1. Imaging and intervention of inferior mesenteric vessels What is an enhanced X-ray?
Mesenteric angiography is the visualization of these arteries and their terminal branches on fluoroscopy or digital subtraction angiography (DSA). In the past, mesenteric angiography played a role in the diagnosis of angiogenic tumors, or vascular diseases involving the gastrointestinal tract. At present, these diseases are usually diagnosed by multislice computed tomography or high-force magnetic resonance imaging combined with dilatation of the intestinal loops with water, then mesenteric arteriography is often indicated in cases of bleeding digestive blood.

2. When is X-ray enhanced mesenteric vasculature and intervention indicated?
Gastrointestinal bleeding not due to varicose veins (usually in portal hypertension or hemorrhoids) that cannot be treated with medical therapy or endoscopic intervention. In some cases, it is necessary to diagnose vascular disease or vascular rich tumors that are not clear on computed tomography.

3. Contraindications of the method of angiography and intervention of lower mesenteric vessels with enhanced X-ray
There are no absolute contraindications. Relative contraindications in the case of patients with coagulopathy, renal failure or allergy to contrast agents (in these cases, contrast agents can be substituted but are very expensive and the image quality is not good). . In the case of severe gastrointestinal bleeding, the patient may be agitated or uncooperative, requiring anesthesia and medication to reduce irritation. Consider if the patient has stopped bleeding unless there is a vascular injury such as a pseudoaneurysm, dysplasia, or an arteriovenous catheter (as seen on computed tomography), intervention is needed because the patient is at risk of bleeding. blood again.

4. Steps for taking and intervening lower mesenteric vessels under enhanced X-ray
Location of puncture: Usually the right femoral artery, in case the right femoral artery cannot be entered (stenosis - occlusion ...), can poke the left femoral artery or brachial artery. Catheterization: Insert the catheter combined with the guide wire to hook into the superior mesenteric artery. Perform an extended scan from the artery to the return of the mesenteric vein. Repeat the operation with the inferior mesenteric artery. Detecting vascular lesions causing gastrointestinal bleeding Using micro-catheters inserted into the lesion site Obstruction with embolizing materials depending on the type of injury and the experience of the interventionist Detecting narrowing of blood vessels: conduct balloon dilation, then place the vascular support according to each specific case. After conducting imaging and intervention of the lower mesenteric vasculature with enhanced X-ray, the patient needs to be assessed the results and handle the complications, if any, to minimize the risk of future effects.
Scanning and intervening lower mesenteric vasculature with enhanced X-ray is a difficult imaging technique that requires expertise in performing the technique, and at the same time, this technique must be performed at medical facilities. has full facilities, modern machinery system, standard photography room. Therefore, in order to achieve accurate diagnostic imaging results, patients need to choose reputable addresses with x-ray machines and modern and standard medical equipment to perform, from which to direct treatment. timely treatment.
