Brain AneurysmsSurgery or minimally-invasive endovascular coiling techniques can be used in the treatment of brain aneurysms. It is important to note, however, that not all aneurysms are treated at the time of diagnosis or are amenable to both forms of treatment. Patients need to consult a neurovascular specialist to determine if they are candidates for either treatment.
Surgical TreatmentTo get to the aneurysm, surgeons must first remove a section of the skull, a procedure called a craniotomy. The surgeon then spreads the brain tissue apart and places a tiny metal clip across the neck to stop blood flow into the aneurysm. After clipping the aneurysm, the bone is secured in its original place, and the wound is closed.
Minimally-Invasive TreatmentCoiling Treatment In Aneurysm
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.
Coil Embolization Or Endovascular Coiling
During this procedure following steps are taken : -
- A small incision is made in the groin through which a tiny catheter is guided through an artery into the brain vessels.
- The catheter is guided carefully guided into the aneurysm
- Soft platinum are deposited through the microcatheter into the aneurysms.
- The coils confirm to the often irregular shape of an aneurysm. An average of 5-6 coils is required for each aneurysm.
- Coils will prevent blood flow into the aneurysm.
