Robot-assisted System Found To Be Feasible For Diagnostic Cerebral Angiography

Digital subtraction angiography remains nan golden modular for diagnosing cerebrovascular diseases, including intracranial aneurysms, arteriovenous malformations, and arterial stenosis. However, nan process requires operators to activity nether fluoroscopic guidance, resulting successful prolonged vulnerability to ionizing radiation. To reside this issue, vascular interventional robotic systems person been developed to let operators to execute procedures remotely from nan radiation zone.

In a study published successful Volume 12 connected January 30, 2026, successful nan Chinese Neurosurgical Journal, Dr. Yuanli Zhao, from Peking Union Medical College Hospital successful Beijing, China, and his squad evaluated nan objective information and efficacy of a domestically produced robot-assisted strategy (YDHB-NS01) for cerebral angiography. The study besides included a reappraisal of nan existent status, advantages, and challenges of robot-assisted exertion successful cerebrovascular interventions.

"The preliminary objective exertion demonstrates that nan YDHB-NS01 robot-assisted strategy is feasible for diagnostic cerebral angiography and shows early indications of information and comparable procedural capacity to those of accepted manual methods," quotes Dr. Zhao.

From May to August 2025, nan squad prospectively enrolled 25 consecutive patients who underwent robot-assisted cerebral angiography and 25 consecutive patients who underwent manual cerebral angiography astatine nan aforesaid center. All procedures were performed by a azygous neurosurgeon. The superior endpoints were method occurrence complaint and objective occurrence rate. Secondary endpoints included process time, fluoroscopy time, diligent radiation dose, opposition supplier volume, full angiography room time, instrumentality capacity evaluation, and complication rate.

All 50 procedures were successfully completed, resulting successful a 100% method and objective occurrence complaint successful some nan robotic-assisted and manual groups. All target vessels were intelligibly visualized and met diagnostic requirements.

The median process clip was importantly shorter successful nan robotic-assisted group than successful nan manual group: 27 minutes versus 38 minutes (p = 0.005). There were nary statistically important differences betwixt nan 2 groups successful fluoroscopy time, diligent radiation dose, opposition supplier volume, aliases full angiography room clip (all p > 0.05).

"There were nary differences betwixt nan 2 groups successful fluoroscopy time, diligent radiation dose, opposition supplier dose, aliases full angiography room time," Dr. Zhao reported.

The robotic strategy operated stably passim nan process without mechanical aliases strategy failures. Operator evaluations reported soft catheter and guidewire delivery, unchangeable manipulator fixation, responsive power handles, and bully unit feedback.

No complications occurred successful immoderate of nan 50 patients. There were nary puncture-related complications and operation-related complications, specified arsenic alloy spasm, injury, perforation, aliases thromboembolism. No neurological complications, including transient ischemic onslaught aliases ischemic stroke, and nary contrast-related adverse reactions. A learning curve was observed successful nan robotic-assisted group. The first 2 cases required longer process times and higher radiation doses, and nan consequent 23 cases showed much unchangeable procedural parameters.

Dr. Zhao describes this investigation arsenic a single-center post-marketing lawsuit series: "Given nan small, single-center cohort and nan exploratory quality of this study, larger multicenter controlled tests are required to corroborate these findings."

In summation to nan objective data, nan article includes a lit reappraisal summarizing nan improvement and objective exertion of various robotic systems successful neurointervention, including their reported method occurrence rates, procedural outcomes, and limitations. The authors statement ongoing challenges, including improving unit feedback, optimizing imaging integration, and enhancing compatibility pinch commercialized devices.
