Transradial surgery appears effective for many neuroendovascular procedures

For years cardiologists have threaded hair-like surgical instruments through arteries in the wrist, as an access point to perform procedures on the heart. For procedures in the brain, however, neurosurgeons more commonly thread instruments through arteries at the groin – a transfemoral approach. In the largest cohort study to date, new research from Jefferson (Philadelphia University + Thomas Jefferson University) demonstrates that transradial surgery, done via the wrist, is safe and effective for a broad range of neuroendovascular procedures, and gives patients faster recovery with less procedural risk.

“Despite improved safety shown in large cardiology trials, transradial brain surgeries via the wrist are much less common,” says senior author of the study and neurosurgeon Pascal Jabbour, MD, Professor of Neurological Surgery and the Chief of the Division of Neurovascular and Endovascular Neurosurgery, and researcher at the Vickie & Jack Farber Institute for Neuroscience — Jefferson Health. “Neurosurgeons tend to prefer the transfemoral approach on which many of us were trained. But our research demonstrates that all kinds of neurological procedures can be done effectively and even more safely via the wrist.”

The results were published in the journal Strokeon July 17.

Dr. Jabbour and his team, including first author Omaditya Khanna, MD, retrospectively examined the medical records of 223 patients treated at Jefferson via the transradial route. The procedures included diagnostic angiograms, mechanical thrombectomies, AVM/AVF embolizations, coiling, stent-assisted-coiling, WEB device placement and flow-diversion treatments of cerebral aneurysms, and carotid stent placement.

A subset of 66 patients who had undergone both transfemoral (groin) and a transradial (wrist) surgeries were selected to complete a satisfaction survey to assess their preference. The majority of patients, 94 percent, said they preferred surgery via the wrist.

In addition, it is easier to ensure a blood vessel in the wrist has clotted, and so patients can go home shortly after surgery, rather than laying horizontally for 4-6 hours after transfemoral surgery.

Laying flat after certain kinds of brain surgery should be avoided in cases with high intracranial pressure, and yet it’s the best way to prevent groin and internal bleeds. For these cases surgery via the wrist is by far the safest option.”

One of the most compelling reasons to change practice, says Dr. Jabbour, is that it eliminates the risk of rare but potentially dangerous complications of post-surgical bleeds in the groin and retroperitoneal area, which can be difficult to detect. A pioneer in the field, Dr. Jabbour was one of the first neurosurgeons to perform brain surgery via the wrist and has continued to teach others this technique.
