An artery coil head is a device that encircles an aneurysm. The main benefit of this procedure is the reduction of the artery’s wall pressure, a benefit that is usually not achieved with other procedures. However, it is not a solution for every situation. Read on to learn more about the procedure, its complications, and the placement of an artery coil head. You will also learn about the benefits and potential risks of this device.
Aneurysms treated with endovascular coiling
Until recently, endovascular coiling (EVC) was the most common treatment for aneurysms in the brain. The procedure can be effective in preventing the rupture of an aneurysm by isolating it from blood flow stresses. It also helps maintain the aneurysm’s wall integrity. Here’s how it works. A team of neurointerventional neurosurgeons and radiologists evaluate aneurysms to determine the best technique.
One of the major benefits of endovascular coiling over surgery is a shorter hospital stay and minimal risk. Endovascular coiling works by introducing a platinum coil inside the aneurysmal sac. This induces thrombus formation, slowing the flow of blood into the aneurysm and reducing the risk of rupture. The number of coils used varies depending on the aneurysm anatomy and the patient’s needs. The procedure is considered complete when thrombosis covers at least 30% of the aneurysm’s volume.
In the past, hemodynamics and aneurysm growth and rupture are intimately linked. Modeling hemodynamics in aneurysms treated with endovascular coiling allows the study of these factors and determine the parameters related to recanalization. The current study aims to develop a numerical model to predict the outcomes of neurosuite coiling. Current models have been validated by experimentation but they cannot predict a treatment outcome accurately.
Patients who undergo an artery coiling procedure need to be monitored for several hours after surgery. If the procedure is successful, patients may be discharged home the same day. However, if the aneurysm ruptures, they may be kept in the hospital for several days or even weeks. Patients are also required to follow strict guidelines regarding their activities for the first two to four weeks after the procedure. This includes no driving, lifting heavy weights, or swimming. After the procedure, patients must return to the hospital for a follow-up appointment and an angiogram three to six months later.
There is a chance that the coils may protrude into the aneurysm neck, which results in incomplete occlusion. During this case, a temporary balloon or stent may be inserted to push the coils back into the aneurysm. If the coils do not completely obstruct the aneurysm, blood can enter the residual neck, allowing it to re-grow. Although these complications are rare, the risk of aneurysm rebleeding is increased immediately following the procedure.
The signs of a successful artery coil head procedure are similar to those of other medical procedures. When a coil is in place, it guides blood through the aneurysm. If an aneurysm is wide, the coils may be guided by an inflatable balloon. The coil is released once it has achieved its desired position. The procedure may require a follow-up angiogram after three to six months.
In the coiling room, you will find large pieces of high-tech scanning equipment. A nurse will shave a small part of your groin, and a radiologist will insert a catheter through that incision into the main blood vessel in your leg. The catheter will then be guided through the other blood vessels of your body, to the brain or the aneurysm. A radiologist will then insert a stent at the end of the catheter.
While there are some risks associated with aneurysm coiling, these risks vary widely. They depend on the location, size, age, and health of the patient. You will be informed of all the risks prior to consenting to the procedure. The risks associated with coiling include stroke-like symptoms and speech problems. Nevertheless, they are small compared to the risks associated with more traditional surgical options. In addition, coiling is a safe and effective way to treat an aneurysm in the brain, which can save many lives.
