ENDOVASCULAR COILING IN INDIA
Endovascular Embolization or Coiling in India
Endovascular embolization, or coiling, uses the natural access to the brain through the bloodstream via arteries to diagnosis and treat brain aneurysms. The goal of the treatment is to safely seal off the aneurysm and stop further blood from entering into the aneurysm and increasing the risk of rupture or possibly rebleeding.
Endovascular treatment of aneurysms is a relatively new phenonmenon, originating in the 1980’s. Dr. Guido Guglielmi, an Italian doctor, and several other researchers, were the visionaries behind the GDG system, or coiling procedure. With the advent of this remarkable new treatment, some patients who were told they had inoperable aneurysms were now given hope and chance for survival. Other patients, because of advanced age, serious medical problems or other factors, could not undergo open brain surgery, so the GDC system became the alternative to their treatment.
Treatment in India
At the start of the procedure you will lie on your back. A trained neurosurgeon will then insert a hollow needle into the femoral artery located in your thigh. Using this needle as a guide, he will insert a thin tube called a catheter into your artery. Once the catheter is inserted, your surgeon will use it to inject a special material called a contrast dye, which will highlight your blood vessels and make them visible on an exterior X-ray monitor. Gradually, he will use the pathway marked out by the contrast dye to pass the catheter up your body through your aorta, past your heart, and up into the brain through one of the four arteries in your neck.
A small incision is made over the artery and a needle is used to puncture the blood vessel. A sheath (hollow thin tube) is then placed in the artery, which provides constant access to the artery. This catheter sheath usually remains in the artery for 24 to 48 hours after the procedure, so that further interventions can be performed, if necessary. Using a catheter (hollow plastic tube) over a guiding wire, the artery leading to the aneurysm is selected. The wire is removed and the catheter is used to inject a contrast dye into the blood stream in order to visualize the normal blood vessels as well as delineate the aneurysm.
Minimally-Invasive TreatmentCoil Embolization or Endovascular Coiling
Endovascular therapy is a minimally invasive procedure that accesses the treatment area from within the blood vessel. In the case of aneurysms, this treatment is called coil embolization, or “coiling”. In contrast to surgery, endovascular coiling does not require open surgery. Instead, physicians use real-time X-ray technology, called fluoroscopic imaging, to visualize the patient’s vascular system and treat the disease from inside the blood vessel.
Endovascular treatment of brain aneurysms involves insertion of a catheter (small plastic tube) into the femoral artery in the patient’s leg and navigating it through the vascular system, into the head and into the aneurysm. Tiny platinum coils are threaded through the catheter and deployed into the aneurysm, blocking blood flow into the aneurysm and preventing rupture. The coils are made of platinum so that they can be visible via X-ray and be flexible enough to conform to the aneurysm shape. This endovascular coiling, or filling, of the aneurysm is called embolization and can be performed under general anesthesia or light sedation. More than 120,080 patients worldwide have been treated with detachable platinum coils. Learn more about the development of detachable platinum coil technology.
