Digital scan to erase the pulse background in the head, face and neck area

The article was professionally consulted by Specialist Doctor I Vo Cong Hien - Radiologist - Radiology Department - Vinmec Nha Trang International General Hospital.

Angiography of the head and neck area with digital erasure of the background allows to clearly see the structure of the arterioles of the face and neck region. Head, face and neck imaging helps to detect pathologies related to vascular malformations in this area.

Angiography of the head and neck area using a digital erasing machine is an imaging technique using iodinated contrast, which allows to show the structure of the arterioles and veins of the head and neck region. Normally, the head and neck area is supplied with blood from the external carotid and subclavian arteries. When pathology is detected, the head and neck area is supplied with blood by the basilar vertebrae or the internal carotid artery.

Angiography of the head, face and neck with a digital erasing machine is indicated in the following cases:
Diseases related to blood vessels of the head and neck such as pseudoaneurysm, arteriovenous catheterization. Assess the blood supply to the tumor in the head and neck area. Suspected trauma, invasive tumor causing bleeding, leaky blood vessels in the head, face and neck area. Assess collateral circulation. Serving electro-optical intervention.

Angiography of the head, face and neck by digitizing the background eraser is performed with the following steps:
Step 1: Anesthetize the patient by asking the patient to lie supine on the table, set up an intravenous line and then administer local anesthesia. General anesthesia can be given before the procedure with pre-anesthetic injection in cases where the patient is agitated, scared, and has no sense of cooperation (children under 5 years old). Step 2: Choose a location to insert the catheter. Most cases of head and neck angiography involve catheterization from the femoral artery and the technique used is Seldinger. If access from the femoral artery is not possible, alternative access is made from the axillary, brachial, or primary carotid or radial arteries. Step 3: Disinfect and anesthetize the needle puncture site, insert the catheter into the vessel. In head and neck angiography, it is necessary to perform angiography of the internal, external, and vertebral arteries. Depending on the location to be taken, the catheter is threaded to that location and contrast is injected with different amounts, pressures, and speeds. For the external carotid artery, the catheter is inserted into the external carotid artery and contrast is injected with an amount of 8ml, pressure 500 PSI, speed 3ml/s, continuous imaging and focusing of the skull in an upright position. and fully tilted. For the internal carotid artery, the catheter was threaded to the internal artery and contrast was injected with an amount of 10ml, pressure 500 PSI, speed 4ml/s, using a digital scanner to erase the background continuously and focus on the skull area. The brain is in an upright position, 45 degrees and fully tilted. For the vertebral artery, a special cannula Vertebral 4-5F is inserted into the left vertebral artery and contrast is injected with an amount of 8ml, pressure 500PSI, speed 3ml/s, continuous and focused imaging. The skull and the posterior fossa are in a straight position, 25 degrees, 45 degrees and completely tilted. For the subclavian artery, the catheter is threaded to the subclavian artery or scapula and injected with medication. Depending on the pathology, the technician can conduct 3D imaging. Step 4: Finish the process of capturing the head, face and neck with a digitizer to remove the background after meeting the requirements. Remove catheter and stop bleeding, apply pressure to the patient. To stop bleeding, apply pressure directly to the puncture site for 15 minutes, then apply pressure for 8 hours. If compression is not available, a special instrument can be used to close the access route. The results of the right head and neck scan show the structure of the cranial artery system, including the inside and outside the skull, which are the external and internal carotid arteries, the vertebral arteries, the anterior cerebral arteries, between and behind the sides. Thereby, allowing to detect damage if any.
Head and neck angiography by digitizing background eraser is a modern imaging technique, which can be used to treat vascular fistula, eye bleeding and head and neck trauma caused by or caused by accident.

Digital erasure of the head, face and neck is an imaging technique that requires a high level of experience of the doctor and the perfect coordination of the patient. In order to achieve high diagnostic efficiency, patients need to choose reputable addresses that have digital scanning machines to erase the background and have modern and standard medical equipment from which to have timely treatment.
