PURPOSE: Robot-assisted, monoplane C-arm angiography systems designed for hybrid operating rooms represent an alternative approach to neuroendovascular procedures. Conversely, non-computer-assisted monoplane systems or conventional biplane systems in angiography suites are widely established. This study aims to evaluate the effectiveness, safety and efficiency of a robotic C-arm angiography system in performing neuroendovascular interventions, including cerebrovascular digital subtraction angiography (DSA), embolization of the middle meningeal artery (MMA) in subdural hematoma, and mechanical thrombectomy for vessel occlusion.
METHODS: All patients undergoing DSA, MMA embolization, or mechanical thrombectomy between July 2020 and December 2024 were retrospectively included. Procedures were performed using a monoplane robotic C-arm system (ARTIS pheno, Siemens Healthineers, Munich, Germany) in a hybrid operating room. Clinical data, procedural details, and imaging outcomes were analyzed. Radiation exposure was assessed by fluoroscopy time, air kerma, and dose-area product (DAP).
RESULTS: A total of 49 procedures were analyzed, including 28 DSAs, 6 MMA embolizations, and 15 mechanical thrombectomies. DSA and MMA embolization (EMMA grade ≥2) achieved 100% procedural success, while mechanical thrombectomies achieved successful reperfusion (mTICI ≥2b) in 93.3% of cases. Median procedure durations were 34.0 (IQR 18.0-45.0) minutes for DSA, 70.0 (IQR 28.0-126.0) minutes for MMA embolization, and 84.0 (IQR 67.0-106.0) minutes for mechanical thrombectomy. Median fluoroscopy times were 5.2 (IQR 2.9-11.5) minutes (DSA), 21.3 (IQR 8.8-36.5) minutes (MMA embolization), and 21.2 (IQR 18.5-42.9) minutes (mechanical thrombectomy). Median DAPs were 7262.5 (IQR 3867.8-11570.8) µGy·m² (DSA), 16135.5 (IQR 8244.2-18216.2) µGy·m² (MMA embolization), and 9875.2 (IQR 6524.3-18455.5) µGy·m² (mechanical thrombectomy). Additional 3D-angiography or cone-beam CT (CBCT) was associated with higher radiation exposure.
CONCLUSION: Basic neuroendovascular procedures can be safely and efficiently performed using a monoplane robotic C-arm in a hybrid operating room, achieving procedural success and radiation exposure levels comparable to conventional biplane systems.
