Robot-Assisted Neurovascular Intervention

Exclusion Criteria15

• Patients who have undergone surgery within 4 weeks prior to study participation or have not fully recovered from surgery.
• Patients who are pregnant or breastfeeding.
• Patients with existing or anticipated vasospasm, bleeding, or severe atheromatous disease.
• Patients allergic to contrast agents used in angiography.
• Patients with renal failure.
• Patients with a history of cardiac events, such as myocardial infarction or superior vena cava (SVC) syndrome, within 3 months prior to study participation, or with existing heart disease.
• Patients unable to cooperate due to difficulty in expressing intent to the extent that the procedure cannot proceed.
• Patients with severe or life-threatening comorbidities that could significantly affect symptom improvement or render the procedure unbeneficial.
• Patients with non-life-threatening comorbidities that prevent proper follow-up for treatment.
• Patients with an ASPECTS score of 0-2 on a pre-treatment non-contrast CT.
• Inability to perform femoral puncture within 60 minutes of completing CT angiography (if CT perfusion is performed, it must be done after CT angiography).
• Absence of a femoral pulse.
• Cases where vascular access is highly challenging, with an anticipated time exceeding 90 minutes from CT angiography to reperfusion.
• Patients suspected to have cerebral artery dissection or atherosclerosis as the cause of stroke.
• Patients where the intracranial occlusion is determined to be chronic based on clinical history, prior imaging, or clinical judgment.
