Neurology & Neurosurgery

Baylor St. Luke’s Medical Center collaborates with Baylor College of Medicine to revolutionize neurosurgical approaches, find innovative uses for technology, and navigate new frontiers. With some of the best brains in neuroscience, our team manages patient care today while developing new treatments for tomorrow.

Pioneers in Deep
Brain Stimulation

A pioneer in deep brain stimulation, Baylor St. Luke’s Medical Center offers the most advanced means of treating Parkinson’s disease and essential tremor. As of 2019, our neurology and neurosurgery program has performed more than 600 DBS implants and manages one of the largest groups of DBS patients.

Our image-guided, robotic DBS implantation system achieves the highest degree of precision available. We offer both conventional, microelectrode recording-guided surgery (during which the patient is awake for part of the procedure) and asleep, image-guided surgery (during which the patient is sound asleep the entire time). We maximize outcomes and minimize side effects by incorporating the latest intraoperative adjuncts and most sophisticated DBS systems, including those with directional steering capability.

In 2016, Baylor St. Luke’s Medical Center was one of the first hospitals in the country to use the Infinity™ Deep Brain Stimulation System, an advanced treatment option for patients with Parkinson’s disease and essential tremor.

And in 2019, we became the first hospital in Texas to use the Vercise™ Gevia™ Deep Brain Stimulation Systems, featuring the Vercise Cartesia™ Directional Lead by Boston Scientific.

“The additional features of this DBS system allow us to better tailor stimulation to each patient’s needs. Because every patient is different, this greater degree of control will be very helpful for individualizing therapy, which translates into better symptom reduction and fewer stimulation-induced side effects for our patients."

Our team is internationally renowned for employing DBS to treat severe psychiatric illnesses, especially OCD and depression. In fact, Baylor St. Luke’s was the first in the world to use the Medtronic Activa RC+S DBS system in a patient with severe, treatment-resistant OCD as part of an NIH-funded research trial. This system is unique in that it allows the clinician to stream real-time brain recordings from the device in addition to providing stimulation. Dr. Sheth and Dr. Wayne Goodman, Chair in Psychiatry at Baylor College of Medicine, collaborated in the trial.

Revolutionizing Tumor Treatment and Removal

As one of the most active pituitary centers in the nation with published superior surgical outcomes, we safely discharge over 90% of our pituitary surgery patients after just one night in the hospital. We utilize a multidisciplinary approach that combines patient management protocol with a less-invasive endonasal surgical technique in which surgeons enter through the nasal passage to remove the pituitary tumor. The patient management protocol emphasizes patient education, early mobilization, and scheduled inpatient and outpatient endocrine assessments that have been shown to decrease hospital stay, complications, and readmission.

The first in Houston to use CyberKnife^® technology to perform stereotactic radiosurgery in a clinical setting for the treatment of intracranial tumors, the Baylor St. Luke’s Medical Center team has built a legacy of advancing the standard of care with pain-free solutions. CyberKnife^® combines intelligent robotics and image guidance to provide a treatment that is so precise that radiation can be sculpted to small complexly shaped lesions near critical structure — including arteriovenous malformations, acoustic neuroma, trigeminal neuralgia, and ocular melanoma.

1st To Bring Applied Artificial Intelligence to Stroke Care in Houston

Baylor St. Luke’s Medical Center is the first in the Greater Houston area to partner with Viz.ai to bring its award-winning software that utilizes artificial intelligence to analyze images for suspected large vessel occlusion (LVO) strokes. Viz.ai is the first FDA-cleared computer-aided triage system.

As one of the leaders in stroke care in Houston and surrounding areas, Baylor St. Luke’s Medical Center continues its commitment to leverage the most advanced innovations to improve access to the most optimal treatments for patients who are suffering an acute stroke. Viz.ai solutions will allow Baylor St. Luke’s to further enhance the power of its stroke care team through rapid detection and notification of suspected LVO strokes and allow stroke specialists to securely communicate to synchronize care and determine the optimal patient treatment decision.

Stroke specialists with access to Viz.ai’s technology can potentially save critical minutes, even hours, in the triage, diagnosis, and treatment of strokes. Combining groundbreaking applied artificial intelligence with seamless communication, Viz.ai’s image analysis facilitates the fast and accurate triage of suspected LVOs in stroke patients and better collaboration between clinicians at comprehensive and referral hospitals. Viz.ai synchronizes care across the whole care team, enabling a new era of “Synchronized Care,” where the right patient gets to the right doctor at the right time.

“Viz.ai’s applied artificial intelligence solutions have been developed by top stroke clinicians and technical experts in the world, and we are excited to be able to bring these transformational technologies to Baylor St. Luke’s and our community,” said Dr. Chethan P. Venkatasubba Rao, medical director of the neuroscience ICU at Baylor St. Luke’s. “Before, we had to make decisions on the fly or quantify the images from the CAT scan, which is a laborious process that can take hours to complete. The Viz.ai software bypasses the guesswork and allows for early intervention, which results in improved outcomes for our patients.”

Viz.ai is transforming hospital workflow and synchronizing stroke care with a cloud-based artificial intelligence system that automatically analyzes CT scans for suspected LVOs. It alerts neurovascular specialists of suspected LVOs, enabling earlier imaging review and better collaboration between specialists.

Patient Story

Life-Altering Treatment for Patients With Parkinson’s Disease

Parkinson’s disease is the second most common degenerative neurological disorder after Alzheimer’s disease. Overall, as many as 1 million Americans are living with Parkinson’s disease, and approximately 60,000 Americans are diagnosed with the disease each year.

And while there’s no cure for this disease, a number of lifestyle changes and oral medications can help manage the movement and tremor problems associated with the disease. These medications may increase or substitute for dopamine, which people with Parkinson’s disease have low concentrations of, but over time, the benefits of these drugs frequently diminish, become less consistent, or become a burden in a patient’s life due to the often intolerable side effects, which include nausea, fatigue, among many more.

That was the case for Rudy Hardy whose symptoms became worse over time despite being on various medications to treat the symptoms. “I’d get very self-conscious about the tremoring and the balance issues,” said Rudy, who is also an avid sports photographer. “Last football season, I shot half of the season, but one day my legs were stiffening up on me. I just didn’t feel right on the field, and that was it.”

In a desperate search for answers after the medications made him very sick, he sought out a life-altering treatment at Baylor St. Luke’s Medical Center after hearing about a groundbreaking procedure: Deep Brain Stimulation. One of the most advanced therapies in the field, deep brain stimulation is a surgical treatment that consists of implanting a device that sends electrical signals to a targeted area of the brain responsible for body movement (also called motor symptoms) caused by Parkinson’s disease. The electrical impulses delivered by deep brain stimulation disrupt the abnormal activity that occurs in the brain’s circuitry, which is causing the symptoms.

There are three areas in the brain that can be targets for deep brain stimulation in patients with Parkinson’s disease. They are the subthalamic nucleus, the globus pallidus internus, and the ventral intermediate nucleus of the thalamus. Each of these areas plays a role in the brain’s circuitry that is responsible for the control of movement.

Dr. Sameer Sheth was the neurosurgeon who performed the procedure on Rudy over the course of two weeks. The goal of the first surgery was to implant the probes into the brain, and the second procedure consists of running the wires from the probes to the implanted battery in the patient’s chest.

“The results have been amazing. As soon as they turned it on, my right hand stopped tremoring. It’s unbelievable,” said Rudy of his experience with the DBS treatment.

Rudy is now retired from his career in law enforcement, but continues to be active in his professional career. He plans to return to Houston Community College in the spring of 2020 to teach Criminal Justice. He’s even considering reconnecting with his passion for sports photography since this activity has always given him so much joy.

Dr. Sheth and Dr. Ashwin Viswanathan, who also are associate professors of Neurosurgery at Baylor College of Medicine, were among the first group of doctors in Texas to use this most advanced version of deep brain stimulation, which includes extremely precise robotic surgery and the latest generation of DBS devices. By bringing these advances to their patients, they seek to make the treatment of Parkinson’s more effective for more patients.

Patient Story

Two-Stage Surgical Procedure to Treat Cervical Degenerative Kyphosis

The cervical spine refers to the portion of the spinal column that is within our neck. This portion of the spine needs to be flexible enough to allow us to turn our head from side to side and up and down but also needs to be strong enough to protect the delicate spinal cord and spinal nerves that travel through it.

If you look at the average person from the side, the neck appears to stand straight up and down. However, there is a normal curve called lordosis that helps keep the head and neck in perfect alignment. When injuries, deformities, or arthritis disrupt this head-neck harmony, it can cause something known as cervical degenerative kyphosis, which reverses the normal lordosis.

For about three years, Linda Cummings experienced firsthand the pain and other uncomfortable and unpleasant side effects of this condition. Her inability to extend her neck without manual assistance, even when she was asleep, worsened over time, interfering with her daily activities and quality of life.

The simplest of daily tasks quickly became challenging undertakings as a result of this condition. “I had resorted to using a towel to prevent my chin from touching my chest when being upright,” said Linda. “I used a walker to help with my balance, but I was still frustrated because I could not see things at normal eye gaze because I was constantly looking at the ground due to this chin-on-chest deformity.”

Imaging studies that were done at Baylor Neurosurgery Spine Clinic, an outpatient center that is part of Baylor St. Luke’s Medical Center, revealed a cervical spine deformity called “chin-on-chest.” She had multiple levels of stenosis, which refers to the narrowing and compressing of the space for the spinal cord or nerve branches in the cervical spine. Cervical stenosis is most frequently caused by aging and degenerative arthritis, but Linda’s stenosis was severe.

Due to the advanced stage of her deformity, Linda was identified as a candidate for a surgical spinal reconstruction that could be performed in two stages. Firstly, a C3-7 anterior cervical discectomy and fusion was performed, followed by a posterior approach for C6-T1 laminectomies, a C7 pedicle subtraction osteotomy, and C2 to T4 instrumented fusion. These surgical procedures were done after Linda underwent cervical traction, a process in which gentle stretching of the neck muscles allowed a temporary partial correction of her deformity, which aided in surgery.

“Large cervical spine deformity surgeries require a multidisciplinary team both in the operating room and the hospital. Our team was able to help this patient through her hospital course, and her surgery was very successful. She looks straight ahead now, rather than at the floor,” said Dr. Alexander Ropper of Baylor Neurosurgery. “Her neck pain and functionality improved dramatically after surgery.”

Cervical spine imaging revealed excellent correction of her deformity.
