Clinical application of a vascular interventional robot in cerebral angiography

Abstract

BACKGROUND: Cardiovascular and cerebrovascular diseases have become the leading cause of death for people, and endovascular surgery has become the main therapeutic method. Robot technology would overcome some limitations of conventional surgery, and has good prospects. METHODS: A total of 15 patients received cerebral angiography assisted by a vascular interventional robot following preoperative examination, with approval from the hospital ethics committee and informed consent by the patients' families. RESULTS: Robot-assisted angiography was performed quickly and smoothly without surgical complications. The remote positioning accuracy was 1.05 ± 0.28 mm. The time staff were exposed to the digital subtraction angiography (DSA) machine was 0 min. The entire experimental process was mechanized and automated. CONCLUSION: This system achieved the preliminary purposes, including a reduction in radiation for the surgeons, facilitation of the application of interventional procedures, a decrease in operation time, and an improvement in operation quality.
