Cerebral angiographic examination - Hospital Medical Information



Justice
Cerebral angiography examination is cerebral vascular injection of contrast medium into and taken X-ray is a test to determine whether or not blood brain damage to the. A catheter is inserted into the femoral artery of the lower extremity or the radial artery of the upper limb and placed in the cerebral blood vessels. The cerebral blood vessels are seen clearly when X-rays are continuously taken for a few seconds while injecting the appropriate amount of contrast agent. In addition, in order to make only the cerebral blood vessels selectively visible, the computer can remove the peripheral shadows other than the cerebral vessels to produce a very vivid cerebral blood vessel image. Cerebral angiography tests are blood-brain tests (using magnetic resonance MR angiography ) or computed tomography (CT) brain angiography examination ( CT angiography and invasive putting foreign objects such as) and conduit, wire in the vascular contrast, may be consequent complications However, it is the most accurate method for the diagnosis of cerebrovascular disease.


Kinds
Common carotid artery imaging tests, carotid angiography examination, other tests carotid angiography, vertebral artery imaging tests

Inspection cycle
Only if there is neurological symptoms or suspicion of cerebrovascular disease on a computerized tomography ( CT ) or magnetic resonance imaging ( MRI ) scan.

Preparations
If the catheter enters the femoral artery , remove both skippings.

method of inspection
Conduit enters vessel the parts of the skin and peripheral vascular local anesthesia , and about 5 mm after adding the incision placed within a catheter in a blood vessel. The catheter is placed in the origin of the cerebral vessel to be examined via the aorta , and continuous blood vessel images are obtained by X-ray imaging at the same time as contrast injection into the catheter . After the test is completed, the catheter is removed and the catheter is inserted by hand for about 10 to 20 minutes. The time required for the patient to lie after the hemostasis depends on the use of anticoagulants and the use of a hemostasis aid, but is approximately 3 to 8 hours.

Time
Approximately 1 to 2 hours

Precautions
For accurate examination, do not move your head when you take a picture , and do not bend or move the leg or arm after hemostasis.

Impression of the head may be burning or blinking as the contrast agent is injected. This is because the natural reaction to be. You should not move your head when taking pictures for accurate examination. If you move the leg or arm after hemostasis, hematoma may occur. Do not move or bend your leg or arm for a fixed time.

Side effects / after effects
Bleeding at the site of the catheter can cause swelling or bruising, and if you become infected , you may need to take antibiotics or perform an operation. An allergic reaction caused by contrast media can lead to urticaria or severe dyspnea. The most serious complication is cerebral vascular permanent due to thrombosis and embolism of nerves as significant damage, or to say eonul from approximately 1% to 2% dubious attack is known to appear like.

Diagnostic disease
Cerebral Aneurysm , Cerebrovascular Stenosis, Stroke , Brain Arteriovenous Malformation , Brain Arteriovenous Fistula, Hypervascular Brain Tumor

Related Test Methods
Computed tomography angiography scan ( CT angiography ), magnetic resonance angiography scan ( MR angiography to determine the, etc.) are similar to tests and the exact diagnosis or treatment plan is the best test of the brain angiography examination.

Gout is associated with the accumulation of uric acid in the body. Uric acid is the final product of degradation caused by metabolism of a substance called purine, a component of nucleic acid, in the liver after the cell has reached its end of life and the nucleic acid has been liberated. Purine, a precursor to uric acid, is ingested through food. When purines are metabolized in the liver and become uric acid, uric acid is excreted in the urine via the kidneys. If you have gout, you should know and eat foods that have high purine content (liver, kidney beans, herring, mackerel, anchovy, etc.). Alcohol as well as diet are closely related to the occurrence of gout. Alcohol reduces the excretion of uric acid in the body, and drink with alcohol is said to increase the amount of uric acid in the blood because of the high purine content. Among beer, beer is known to cause gout attacks most commonly because of the presence of purine in beer. Regardless of the type and amount of alc...

Gout occurs when suddenly the toe, the wind only hurts (even graze 痛風 will feel severe pain enough to be very high expression). This is because leukocytes in the body are severely inflamed during the process of eliminating the uric acid crystals formed in the joints or around the joints. At this time, anti-inflammatory treatment should be started with ice fomentation. The most commonly used is oral anti-inflammatory (anti-inflammatory) agent. If these anti-inflammatory treatments are done early, most focal gout attacks are effectively treated. Gout attacks usually do not require anti-inflammatory treatment, but the inflammation gradually improves over time. However, without proper antiinflammatory treatment, arthralgia can last for weeks, so it is advisable to start anti-inflammatory treatment as soon as you have gout attacks. If the joint is still uncomfortable even though you think it has passed, you may still have symptoms because the severe inflammation has not co...

Cerebral aneurysm - Hospital Medical Information

Justice It refers to the case where the inner elastic layer and the middle membrane forming the inner part of the cerebral blood vessel are damaged and deficient and the blood vessel walls swell up to form a new intravascular space. More than 90% are found in the thick cerebral artery of the brain at the base of the brain called Willis ( circle of Willis ) and the rest are distal (the proximal part of the blood vessel near the heart , the distal part farther away, Which supplies blood directly to the brain ) occurs in the cerebral arteries, or in the arteries that are responsible for the larynx or horseshoe of the brain . Most cases are less than 10 mm in size but occasionally larger aneurysms may develop. More than 25 mm is referred to as a giant aneurysm. The aneurysm is divided into a cystic aneurysm, a pseudoaneurysm, and a dissecting aneurysm. Types of aneurysms Types of aneurysms cause The exact cause of the aneurysm is unknown yet. However , it is presumed that an...
