Dr. Marc A Vanefsky has the following 2 specialties
- Neurological Surgery
A neurological surgeon is a physician who surgically treats disorders of the nervous system, which is comprised of the brain, spinal cord and nerves.
In addition to treating trauma of the head and spine, these doctors also treat disorders like epilepsy, aneurysms, hydrocephalus, Parkinson's disease, multiple sclerosis, stroke, spinal disc herniation, and spinal disease.
Neurological surgeons can perform surgical procedures on the brain, such as stereotactic surgery, microsurgery, endoscopic surgery, stereotactic radiosurgery, and endovascular image guided methods.
A neurologist is a physician who diagnoses and treats disorders of the nervous system which is comprised of the brain, spinal cord and nerves. These doctors do not perform surgery, but refer patients to neurological surgeons when they determine that surgical intervention is necessary.
Some of the conditions that neurologists diagnose and treat are epilepsy, aneurysms, hydrocephalus, Parkinson's disease, multiple sclerosis, stroke, spinal disc herniation, and spinal disease.
In addition to using diagnostic tests like MRI, CT scans, EEG and EMG, neurologists also employ neurological testing to gauge muscle strength and movement, balance, reflexes, sensation, memory, speech, and other cognitive abilities.

I suffered 2 (yes 2) brain aneurysms. I was given a 1% chance of survival. My family was advised to make funeral arrangements. Anyway, I had to be transferred to 3 different hospitals because there really aren't that many Neurosurgeons trained in coiling/clamping aneurysms at the Kaisers in my area. Luckily I was Blessed to be treated by Dr Marc Vanefsky. He had to perform 4 separate surgeries to correct the damage that was done after both aneurysms ruptured. After my surgeries, I had to learn to walk & talk again. Due to my brain trauma I had to spend quite a while in the hospital (mostly in ICU) then I saw Dr Marc weekly for follow-ups & to make sure I was progressing as expected. I constantly thank God every day he became my Neurosurgeon. He always gave me whatever time was needed & had the patience to take excellent care of me. He was completely & totally accurate in all he did to ensure I would return to as 'normal' as possible. He spent quite a lot of time with me & always answered my questions accurately & with patience. If I still had Kaiser Insurance I would still be going to him for my brain check-ups. Sadly, I have been deteriorating because the only doctors I see now are interns training at County hospitals. They try but are not quite 'there' yet. I am hoping Dr Vanefsky will be available when my insurance kicks in. Thank you Dr. Marc!!!
Our family was introduced to Dr Marc Vanefsky when my father was diagnosed with brain cancer. Our first impression was one of a professional medical doctor. That, however, changed rapidly. When we presented him the MRI scans (which we had to obtain ourselves), he advised that he could not determine the pathology (re: staging or grading) of the brain tumor until he performed a craniotomy on my father. He advised the mass was located in the left frontal lobe but that he would need to do surgery in order to determine whether it was malignant or benign. He also advised that the craniotomy would consist of him removing "as much of the tumor as possible without damaging surrounding brain structures" in order for my dad to stand a chance at the best possible outcome. After a two hour surgery, we received a call that the procedure was complete. After approximately two weeks of recovery, we had a follow-up appt. with Dr Vanefsky to discuss the results of the craniotomy, as well as the pathology. As he showed us the post-op MRI scans, he advised that what appeared to be tumor was actually where he had removed tumor tissue and that he had removed as much of it as was possible. I asked him directly if the areas he had just pointed out was tumor tissue and he advised it was "just empty space" and that the brain "would fill in on itself". We then had to make a separate appointment several days later to find out whether the tumor was malignant or benign. We waited in the exam room for approximately 30-40 minutes before being seen. As the appointment was made with Dr Vanefsky, we expected to see and discuss our next steps with him. However, he sent his Physician's Assistant in his place to deliver us the news that my father had about nine months to live. That experience was horrible; but to have that kind of news delivered by anyone other than my father's neurosurgeon was disgraceful. We were told he was "busy" with another patient & couldn't make it in to see my dad or our family! The final blow came when we had a second opinion and that doctor advised us that based upon my father's surgical scar and the post-op MRI scans, Dr Vanefsky had only done a biopsy (had not debulked the tumor) and that the "spaces" we were seeing in the scans were actually malignant tumor tissue. Yet another blow to our family as we realized Dr Vanefsky had lied to us on more than one occasion. I would NEVER recommend Dr Marc Vanefsky! His bedside manner was non-existent. He should not be a practicing neurosurgeon as his priorities are obviously elsewhere. I would advise very strongly against placing your trust and/or life in his hands. He is not capable and he showed our family a complete lack of interest in my father's care. Our experience with him was damaging and I would wish this doctor (I use that term very loosely) on no one. His incompetence is based upon the fact that he clearly does not care about his patients. He sees each of them as a number and another dollar on his paycheck. Stay as far away from this doctor as possible.
