Moyamoya disease is a rare cerebrovascular disorder that hinders brain blood flow, leading to an increased risk of stroke. At the Atlas Institute of Brain and Spine, located in Los Angeles, CA, we specialize in providing comprehensive care for this complex condition, particularly through surgical options like bypass surgery. With Dr. Aaron Cohen-Gadol, the founder and President of the Atlas Institute, who has performed over 7,500 complex brain surgeries, leading our practice, patients can expect world-class expertise in managing Moyamoya disease and its intricate treatment pathways.
Dr. Cohen took care of my son who had an AVM (Arteriovenous Malformation). Dr. Cohen recommended surgical removal, which was not what neurosurgeons we had seen before recommended. It was a shock, but he walked us through all the options and why he felt surgery was best.
Our son’s case was very complicated and Dr. Cohen was always kind, caring and compassionate. He successfully performed a very intricate surgery that removed the AVM and our son is doing so well! I can’t imagine having any other neurosurgeon!
How Moyamoya Disease Affects Brain Blood Flow
Moyamoya disease is characterized by stenosis of the internal carotid arteries, resulting in diminished blood supply to the brain. This reduction significantly raises the likelihood of stroke and other neurological complications. A nationwide study involving 18,480 patients with Moyamoya disease found that those who underwent extracranial-intracranial bypass surgery had a significantly lower risk of all-cause mortality compared to those who received nonsurgical treatment. Early diagnosis and intervention are crucial. Imaging techniques such as MRI are key in assessing the degree of vascular impairment and determining the most effective surgical options available to restore cerebral blood flow.
Explore Surgical Intervention Options for Moyamoya Disease
When it comes to treating Moyamoya disease, surgical revascularization is often the most effective approach. There are primarily two types of bypass surgeries: direct and indirect. Each type has specific indications and benefits depending on the patient’s unique condition. Understanding these surgical interventions is vital for effectively addressing the risks associated with diminished blood flow to the brain. Dr. Cohen-Gadol combines extensive experience, having mentored hundreds of neurosurgeons, with innovative techniques for optimal care.


Discover Direct Bypass Surgery Techniques in Neurosurgery
Direct bypass surgery is a technique that aims to quickly restore blood flow to the brain by connecting a donor artery to the affected area. This approach may be highly beneficial for patients with significant stenosis and a higher risk of stroke. Through meticulous planning and advanced surgical techniques, Dr. Cohen-Gadol and our experienced team aim to maximize patient safety and surgical effectiveness during these procedures. Research indicates that bypass surgery can reduce the risk of stroke recurrence in adult patients with hemorrhagic Moyamoya disease, highlighting the importance of timely intervention.
Learn About Indirect Bypass Surgery Benefits
Indirect bypass surgery, on the other hand, facilitates a more gradual restoration of blood flow by promoting the development of collateral circulation. This technique can play a pivotal role for patients whose condition requires a gentler approach. A study involving 25 patients treated surgically for Moyamoya disease found that 88.9% of adults undergoing bypass surgery had no neurological deterioration over a follow-up period averaging 27.7 months. Our practice emphasizes tailoring surgical options to fit the individual’s specific needs, ensuring personalized care throughout the treatment process.
