Los Angeles neurosurgeon draws AVM patients from around the world

Patients with brain arteriovenous malformations and cavernous malformations are traveling to Los Angeles for surgery with Dr. Aaron Cohen-Gadol, who has treated more than 1,200 of these cases. The surge reflects how much experience can matter when patients are deciding whether a lesion is safe to remove or too risky to touch.

Why it matters: - Brain AVMs and cavernous malformations can rupture and cause life-threatening bleeding. - For many patients, the hardest decision is whether surgery is safer than leaving the lesion untreated. - Dr. Aaron Cohen-Gadol’s volume of more than 1,200 AVM and cavernous malformation surgeries gives patients a rare high-experience option.

What happened: - Patients are traveling to Los Angeles, including from other states and other countries, for evaluation and surgery with Dr. Aaron Cohen-Gadol. - Dr. Cohen-Gadol has surgically treated more than 1,200 AVMs and cavernous malformations during his career. - Dr. Cohen-Gadol performs surgery at Cedars-Sinai Medical Center and Saint John’s Health Center in Los Angeles. - Dr. Cohen-Gadol leads the ATLAS Institute of Brain and Spine.

The details: - AVMs are tangles of abnormal blood vessels where arteries connect directly to veins without the normal capillary network. - That abnormal structure leaves vessel walls fragile and vulnerable to rupture. - AVMs and cavernous malformations are rare, and many neurosurgeons see relatively few complex cases. - Each AVM has its own mix of feeding arteries, draining veins, and nearby brain tissue. - Surgical planning depends on identifying the safest path through that anatomy. - Dr. Cohen-Gadol is frequently sought for second opinions on lesions considered inoperable or too risky elsewhere, including deep brain lesions and those near critical neurological structures. - Dr. Cohen-Gadol has performed more than 7,500 complex brain surgeries overall. - Dr. Cohen-Gadol has authored more than 600 peer-reviewed publications. - Dr. Cohen-Gadol has refined more than 40 neurosurgical operations. - Dr. Cohen-Gadol founded the Neurosurgical Atlas, which the release says is used by more than 70,000 physicians and surgeons worldwide. - Dr. Cohen-Gadol received the Vilhelm Magnus Medal from the Scandinavian Neurosurgical Society. - The release describes that honor as sometimes considered neurosurgery’s equivalent of a Nobel Prize. - Dr. Cohen-Gadol’s office offers remote second-opinion consultations. - Patients can have imaging and angiography reviewed before deciding whether to travel to Los Angeles. - Patients can contact Dr. Cohen-Gadol’s office at (310) 626-1312. - More information is available on the company's announcement. - Social links listed in the release include Instagram and Facebook.

Between the lines: - The release frames experience as a key differentiator because AVM grading systems do not capture a surgeon’s individual judgment. - The pitch is aimed at patients who have already been told their lesion is inoperable or excessively risky. - Remote review lowers the barrier to a second opinion before a patient commits to travel. - The focus on high-volume surgery suggests the practice is positioning itself around cases other surgeons may decline.

What's next: - Patients with AVMs or cavernous malformations can seek either virtual or in-person consultation before deciding on treatment. - The release suggests some patients may travel to Los Angeles only after imaging review shows surgery is a realistic option. - Dr. Cohen-Gadol’s practice is likely to continue drawing referral traffic from patients seeking another opinion on complex vascular malformations.
