What is the coil embolization?

coil embolization describes minimally invasive surgery to treat aneurysms and fistula in the brain. Through the catheter inserted into the weakness, small coils are led to the brain and separated from the catheter to block blood flow to aneurysm or fistula. One or more platinum coils are left in place to prevent aneurysm to prevent.

neuroradiologist or neurosurgeon usually performs a procedure in a hospital environment. The surgeon cuts a small slot in a weakness to access femoral artery. Using a dye to make the aneurysm visible in the computer image, the doctor stretches the catheter through the artery. As an aneurysm is approaching, the surgeon releases the coils from the catheter. The body produces a blood clot around the coils for blocking blood flow.

Aneurysm is a bulge or bag in the weak wall of the artery. The stretching could put pressure on tissues and nerves in the brain, causing paralysis. It can also crack, leading to a stroke or death. The coilembolization could be afterUsed after aneurysm rip to repair damage or before breaking as a preventive measure.

Aneurysm symptoms include headache, nausea or vomiting and upper back and neck pain. If these symptoms exist, doctors normally perform imaging tests to determine whether an aneurysm is present. The coil embolization is usually recommended when the patient cannot undergo brain surgery to prevent rupture.

fistula defines the opening between the veins and the arteries, which reduces the blood flow rich in oxygen into the brain. These abnormal gaps normally cause pressure in the eye, the main sign of glaucoma. Some fistulas cause dual vision, pain and unusual sounds in the ears such as humming.

There is an alternative option if the coil cannot be embolized due to the size or location of the aneurysm. If the bulge is relatively large or appears on the skull base, the ball OccluzE can work. This procedure uses inflated balloons to reduce blood flow. The process is similar to the coil embolization with the catheterization of the femoral artery.

The risks of the procedure are considered to be low, but stroke may occur during the coil embolization. When this happens, the patient may suffer from a weakness in his leg or arm. There may also be problems of speech and vision.

After the coil is located, patients remain flat for eight or more hours to recover the femoral artery. A day or two later they normally return home. After a few months, an angiogram can be performed to see if the coils remain in the position.
