Hi, I’m Dr. Dharav Kheradia, a neurointerventionist with over a decade of experience in treating various vascular conditions, including brain aneurysms. Today, I want to discuss the exciting advancements in minimally invasive techniques for treating these potentially life-threatening bulges in the brain’s blood vessels.
Brain aneurysms occur when a weak spot in an artery wall balloons outward, creating a pouch. If left untreated, they can rupture, causing a hemorrhagic stroke, which is often fatal or debilitating. Thankfully, with early detection and advancements in treatment techniques, we can significantly improve patient outcomes.
Ruptured Brain Aneurysm

Aneurysm Treatment: Traditional Approach:
In the past, the primary treatment for brain aneurysms was open surgical clipping. This procedure involves making an incision in the skull, exposing the aneurysm, and placing a tiny metal clip at its base to block blood flow and prevent rupture. While effective, this approach is highly invasive, requiring general anesthesia and a longer recovery period.
Coiling Techniques:
Minimally Invasive Endovascular Coiling
Fortunately, minimally invasive endovascular coiling has emerged as a game-changer in aneurysm treatment. This technique involves accessing the aneurysm through a thin catheter inserted in the groin artery and navigated through the body’s blood vessels to reach the brain. Once positioned, soft, platinum coils are deployed within the aneurysm sac. These coils promote blood clotting (thrombosis), effectively blocking blood flow into the aneurysm and reducing the risk of rupture. This prevents blood from reaching the weakened area of the artery wall, thereby mitigating the risk of a potential rupture and bleeding in the brain.
Coiling offers several advantages over traditional surgery:
- Minimally invasive: This reduces the risk of complications associated with major surgery.
- Faster recovery: Patients typically experience shorter hospital stays and quicker return to daily activities.
- Improved visualization: Modern coiling techniques utilize sophisticated imaging tools, allowing for greater precision and safety during the procedure.
Advancements in Coiling:
The field of coiling is constantly evolving, with newer technologies further enhancing its effectiveness:
- Improved coil materials: Newer coils are designed to be softer and more adaptable, allowing for better packing and stability within the aneurysm.
- Balloon-assisted coiling: This technique utilizes a small balloon to temporarily widen the neck of the aneurysm, facilitating the placement of coils in wider-necked aneurysms.
- Stent-assisted coiling: For complex aneurysm shapes, stents (tiny mesh tubes) can be deployed alongside coils to provide additional support and prevent coil prolapse.
- Microcoils: These smaller coils are particularly beneficial for treating smaller aneurysms.
Flow Diversion Devices:
For complex or wide-necked aneurysms unsuitable for coiling, flow diversion presents a newer, promising approach. These specialized stents are placed within the parent artery, just above the aneurysm. By redirecting blood flow away from the aneurysm sac, they promote blood clotting within the pouch, ultimately leading to its closure.
Flow diversion offers several advantages:
- Effective treatment for complex aneurysms: This approach provides a valuable option for treating aneurysms previously considered untreatable with traditional coiling.
- Potentially higher long-term success rates: Studies suggest flow diversion may offer higher long-term success rates for specific types of aneurysms.
It is important to note that flow diversion carries unique potential risks compared to coiling, such as a slightly higher risk of stroke. However, experienced neurointerventionists carefully weigh the risks and benefits for each individual patient to determine the most suitable treatment approach.
The development of coiling and flow diversion techniques has significantly improved our ability to treat brain aneurysms with minimal invasiveness and faster recovery times. Ongoing research continues to refine these techniques and explore new advancements. However, early diagnosis remains crucial for successful treatment.
