Patients Travel to Los Angeles for Brain Vascular Malformation Surgery from a Surgeon Who Has Treated Over 1,200

Dr. Aaron Cohen-Gadol has treated 1,200+ AVMs and cavernous malformations, including lesions other surgeons consider too dangerous to remove.

LOS ANGELES, CA, UNITED STATES, September 2, 2026 /EINPresswire.com/ — A brain arteriovenous malformation (AVM) is a tangle of abnormal blood vessels in which arteries connect directly to veins without the normal capillary network between them, leaving vessel walls fragile and vulnerable to rupture. For patients diagnosed with an AVM, the critical question is often whether removing it carries greater risk than leaving it untreated.

Increasingly, patients facing that decision are traveling across the country and internationally to be evaluated by Dr. Aaron Cohen-Gadol, a Los Angeles–based neurosurgeon who has surgically treated more than 1,200 AVMs and cavernous malformations during his career.

**Experience Built Over More Than 1,200 Cases**

AVMs and cavernous malformations are rare, and many neurosurgeons encounter relatively few complex cases during their careers. Dr. Cohen-Gadol’s experience places him among a small group of surgeons with extensive surgical experience treating these conditions.

Every AVM has a unique architecture of feeding arteries, draining veins, and surrounding brain tissue. Identifying the safest surgical pathway requires judgment developed case by case. Dr. Cohen-Gadol has built that pattern recognition through more than 1,200 vascular malformation surgeries.

He is frequently sought for second opinions on AVMs and cavernous malformations considered inoperable or excessively high-risk elsewhere, including lesions located deep within the brain or near critical neurological structures.

Dr. Cohen-Gadol is also one of a small number of neurosurgeons worldwide to receive the Vilhelm Magnus Medal from the Scandinavian Neurosurgical Society, an honor sometimes described as neurosurgery’s equivalent of a Nobel Prize.

As founder of the *Neurosurgical Atlas*, used by more than 70,000 physicians and surgeons worldwide, he has spent decades studying, refining, and teaching advanced neurosurgical techniques, including AVM resection.

**Why Surgical Experience Matters**

Surgeons classify AVMs according to factors including size, location, and venous drainage, which help estimate surgical risk. These grading systems, however, cannot account for the individual surgeon’s experience.

For lower-grade AVMs and many cavernous malformations, surgery in experienced hands can offer a high rate of cure, immediate elimination of future rupture risk, and a low complication rate.

Higher-grade and deep-seated lesions carry greater inherent risk. In these cases, extensive surgical experience becomes especially important because treatment decisions depend heavily on recognizing anatomy, selecting the safest surgical approach, and adapting during the operation.

“The technical literature will tell you how an AVM is graded, but it cannot tell you what fifteen hundred cases feel like in your hands,” said Dr. Cohen-Gadol. “Every one of these lesions is a little different, and a surgeon’s ability to recognize the safest plane through that anatomy is something you build one case at a time. That experience is what allows me to offer patients a genuinely low-risk path to a cure, even for lesions that have been called too dangerous to touch elsewhere.”

**Why Patients Travel for Treatment**

Dr. Cohen-Gadol has performed more than 7,500 complex brain surgeries overall, including more than 1,200 surgical treatments of AVMs and cavernous malformations.

He is widely sought for second opinions on vascular malformations labeled inoperable or high-risk elsewhere and has authored more than 600 peer-reviewed publications while refining more than 40 neurosurgical operations.

His practice also offers remote second-opinion consultations, allowing patients to have their imaging and angiography reviewed before deciding whether travel to Los Angeles is necessary.

**A Second Opinion Before a Plane Ticket**

Dr. Cohen-Gadol performs surgery at Cedars-Sinai Medical Center and Saint John’s Health Center in Los Angeles, where he leads the ATLAS Institute of Brain and Spine.

Both in-person and virtual consultations are available, allowing patients anywhere in the world to have their cases reviewed directly by Dr. Cohen-Gadol before making treatment or travel decisions.

Patients who have been told their AVM or cavernous malformation is inoperable, or who want another opinion from a surgeon with extensive vascular malformation experience, can contact Dr. Cohen-Gadol’s office at (310) 626-1312 or visit [www.aaroncohen-gadol.com](http://www.aaroncohen-gadol.com).
