Treat complex or wide-neck brain aneurysms without open surgery using advanced flow-diverting stents, or “pipelines,” designed for long-term protection.
Flow diversion is a cutting-edge, minimally invasive treatment used to manage complex brain aneurysms, especially large or wide-neck aneurysms that are not ideal candidates for coiling or surgical clipping. Instead of filling the aneurysm, this procedure redirects blood flow away from the aneurysm using a specialized device called a flow-diverting stent, such as the Pipeline Embolization Device.
During this endovascular treatment, Dr. Parham Yashar inserts the stent through a catheter into the artery and places it across the neck of the aneurysm. Over time, the diverted blood flow promotes natural healing as the aneurysm shrinks and the artery wall reconstructs itself.
Flow diversion offers durable results with a lower chance of recurrence, making it an excellent option for patients who need a long-term solution with minimal recovery time.
Flow diversion may be recommended by Dr. Yashar if:
Conditions commonly treated with flow diversion include:
You’ll be placed under general anesthesia for comfort and safety.
A catheter is inserted into an artery (typically in the groin or wrist) and guided through the vascular system to the aneurysm.
Dr. Yashar places the flow-diverting stent across the neck of the aneurysm to reroute blood flow and promote vessel healing.
Over the following weeks to months, the diverted flow reduces pressure inside the aneurysm, leading to gradual closure and wall reconstruction.
Flow diversion is typically well-tolerated and involves minimal downtime. Most patients experience:
This treatment is particularly valuable for patients seeking a durable, low-maintenance solution for brain aneurysms not suitable for traditional therapies.
For certain aneurysms, especially large or wide-neck ones, yes. Flow diversion offers better long-term outcomes and eliminates the need to fill the aneurysm with coils.
Though rare, risks include blood clots, in-stent thrombosis, vessel injury, or delayed aneurysm occlusion. Dr. Yashar carefully evaluates each case and uses pre-procedure imaging and blood thinners to minimize these risks.
The pipeline device is a permanent implant. It integrates with the blood vessel wall over time, becoming part of the artery’s structure.
In some cases, yes, especially if multiple aneurysms are located along the same artery segment. Dr. Yashar will determine the best strategy based on your vascular anatomy.
Unlike coiling, most patients do not require repeat procedures. Imaging follow-ups help ensure the device continues to perform as intended.
