Subclavian steal-carotid recovery phenomenon due to innominate artery occlusion: Doppler ultrasound and digital subtraction angiography findings and endovascular treatment

To evaluate the feasibility and safety of the robot of endovascular treatment (RobEnt) in clinical practice, we carried out a cerebral angiography using this robot system. We evaluated the performance of application of the robot system to clinical practice through using this robotic system to perform the digital subtraction angiography for a patient who was suspected of suffering intracranial aneurysm. At the same time, through comparing the postoperative head nuclear magnetic and blood routine with the preoperative examination, we evaluated the safety of application of the robot system to clinical practice. We performed the robot system to complete the bilateral carotid artery and bilateral vertebral arteriography. The results indicate that there was no obvious abnormality in the patient’s cerebral artery. No obvious abnormality was observed in the examination of patients’ check-up, head nuclear magnetism, and blood routine after the digital subtraction angiography. From this clinical trial, it can be observed that the robot system can perform the operation of cerebral angiography. The robot system can basically complete the related observation indexes, and its accuracy, effectiveness, stability, and safety basically meet the requirements of clinical application in neurointerventional surgery.

Technical Considerations

Several studies have been published on the usefulness of MR angiography of carotid bifurcations and epiaortic vessels. Almost all of them were carried out with the Time-of-Flight technique, most of them using the 2D acquisition modality. These studies claim a good overall sensitivity and specificity by comparison to digital subtraction angiography, Doppler ultrasound or both in the demonstration of carotid clinically relevant stenosis, with a slight overestimation of the degree of stenosis, especially in the moderate and severe groups. Unlike Doppler ultrasound, distal cervical and proximal intracranial arteries can be relatively well evaluated by MR angiography. Nevertheless, MR angiography also has limitations, among the best known, difficult visualization of the origin of neck arteries, inaccurate depiction of vessel morphology in case of complex flow and unreliable quantification of the degree of stenosis have to be mentioned. To get the most of the diagnostic potential of MR angiography, imaging strategies and technical considerations have to be adapted to the morphological and hemodynamic particularities of the different segments of the supraaortic arterial structures.
