Surgeons successfully treat brain aneurysms using a robot

Summary: Doctors have successfully used robotic technology to treat brain aneurysms. The robotic system could eventually allow remote surgery, enabling surgeons to treat brain disorders that require surgery from afar.

Using a robot to treat brain aneurysms is feasible and could allow for improved precision when placing stents, coils and other devices, according to late breaking science presented today at the American Stroke Association’s International Stroke Conference 2020 . The conference, Feb. 19-21 in Los Angeles, is a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health.

Robotic technology is used in surgery and cardiology, but not for brain vascular procedures. In this study, Canadian researchers report the results of the first robotic brain vascular procedures. They used a robotic system specifically adapted for neurovascular procedures. Software and hardware adaptations enable it to accommodate microcatheters, guidewires and the other devices used for endovascular procedures in the brain. These modifications also provide the operator additional precise fine-motor control compared to previous system models.

“This experience is the first step towards achieving our vision of remote neurovascular procedures,” said lead researcher Vitor Mendes Pereira, M.D., M.Sc., a neurosurgeon and neuroradiologist at the Toronto Western Hospital, and professor of medical imaging and surgery at the University of Toronto in Canada. “The ability to robotically perform intracranial aneurysm treatment is a major step forward in neuro-endovascular intervention.”

In the first case, a 64-year-old female patient presented with an unruptured aneurysm at the base of her skull. The surgical team successfully used the robot to place a stent and then, using the same microcatheter, entered the aneurysm sac and secured the aneurysm by placing various coils. All intracranial steps were performed with the robotic arm. Since this first case, the team has successfully performed five additional aneurysm treatments using the robot, which included deploying various devices such as flow-diverting stents.

“The expectation is that future robotic systems will be able to be controlled remotely. For example, I could be at my hospital and deliver therapy to a patient hundreds or even thousands of kilometers away,” Mendes Pereira said. “The ability to deliver rapid care through remote robotics for time-critical procedures such as stroke could have a huge impact on improving patient outcomes and allow us to deliver cutting-edge care to patients everywhere, regardless of geography.”

“Our experience, and that of future operators of this technology, will help develop the workflows and processes necessary to implement successful robotic programs, which will ultimately help establish remote care networks in the future,” Mendes Pereira said.

The list of study authors and disclosures are available in the abstract. The work reported was funded by institutional sources. Single patient-use cassettes were provided by Corindus, a Siemens Healthineers Company.
