Background erasing digitized aortic angiography

The article was professionally consulted by Specialist Doctor I Tran Cong Trinh - Radiologist - Radiology Department - Vinmec Central Park International General Hospital. The doctor has many years of experience in the field of diagnostic imaging.

Digital scanning of the background will help detect abnormalities of blood flow early to diagnose and treat accurately diseases related to blood circulation, identify the correct location of damage in the body.

Digital subtraction angiography is an imaging method that combines X-ray and digital image processing to capture the vascular system in the body, while using minimally invasive techniques to Intravascular interventions without the use of invasive open surgery. The structure of the digitized background erasure angiography system usually includes: Display unit; X-ray generator; image acquisition unit; digital image processing unit.
The principle of digital erasure imaging system is to use fluorescence light together with X-ray to take angiogram at the locations that the doctor needs to explore before injecting contrast and after injecting contrast material into the vessel. blood to be taken. In addition, the digitized aortic system erases the background, and to clarify the vascular system, the computer will erase the background image.
Digital scanning of the background will help detect blood flow abnormalities early to diagnose and treat accurately diseases related to blood circulation, pinpoint the correct location of damage in the body.

Indications for digitalized angiography to remove background when:
According to professional requirements Chest trauma, suspected pulmonary vascular injury Tumors in the lung, mediastinum with suspected vascular invasion Congenital and acquired diseases of the system Pulmonary vascular preparation, for interventional radiology Contraindications for digital angiography with background erasure when:
There is no absolute contraindication to background digitized angiography Relative contraindications in the field Patients with coagulopathy, renal failure, allergy to contrast agents and pregnant women.

Digital background erasure angiography is an invasive imaging technique and carries a risk of complications. Before the scan, the patient must fast for 6 hours and do related tests. Here are the steps to perform a digitized aortic angiogram with background erasure:
Step 1: Place the patient on the imaging table, with an intravenous line. Then local anesthetic.

Step 2: Disinfect and anesthetize the puncture site and place the catheter into the vein. Insert a 4 or 5F catheter from the femoral vein, through the inferior vena cava to the right atrium, and then into the right ventricle.
Step 3: Inject contrast agent into the vessel. When the contrast agent enters the blood vessel, the machine will pick up the preset animation.
Step 4: After capturing the background image of the vascular system to be examined, the catheter and tube are pulled into the vessel lumen and then manually pressed directly on the needle puncture site, then ask the patient to lie down for 24 hours. hour.
