Stent-assisted coiling is a specialized, minimally invasive technique used to treat wide-neck or complex brain aneurysms that cannot be safely treated with coiling alone. During this procedure, Dr. Parham Yashar, the best brain surgeon in Los Angeles, places a small, permanent stent inside the parent blood vessel across the neck of the aneurysm. This stent acts as a scaffold, holding the coils in place and preventing them from protruding into the vessel, which improves the stability and long-term success of the treatment.
As both an open and endovascular neurosurgeon, Dr. Yashar uses advanced imaging and meticulous technique to perform stent-assisted coiling with a focus on patient safety and aneurysm durability. This approach allows for precise treatment of otherwise high-risk aneurysms without the need for open brain surgery.
Stent-assisted coiling is typically recommended when:
Conditions commonly treated with stent-assisted coiling include:
General anesthesia is used for comfort and to ensure absolute precision during the procedure.
A catheter is inserted through an artery in the groin or wrist and guided through the vascular system to the aneurysm site using fluoroscopy.
A self-expanding stent is placed across the neck of the aneurysm within the parent artery, creating a barrier to support the coils.
Platinum coils are inserted through a microcatheter and packed into the aneurysm sac. The stent prevents the coils from slipping into the vessel and ensures they remain securely in place.
Once the coils are deployed and the aneurysm is sealed off from blood flow, the catheters are removed.
Stent-assisted coiling offers excellent long-term results for many complex aneurysms, with the benefit of a minimally invasive approach. Recovery highlights include:
In most cases, antiplatelet medication will be prescribed to prevent clot formation around the stent.
