Objective To explore the application of extraction technology with radial artery in the high-flow cerebrovascular bypass surgery. Methods Thirty-two patients of high-flow bypass surgery with radial artery as a bridging vessel admitted to the Department of Neurosurgery, Tianjin HuanHu Hospital from January 2015 to June 2021 were enrolled retrospectively. The length, internal diameter, peak systolic velocity, end diastolic velocity, intima-media thickness and resistance index of radial artery were measured. The imaging data and medical records were also utilized to assess the safety and efficacy including surgery effect, postoperative complication and patency rate of the radial artery. Results No perioperative death was found in this study. Thirty-two patients had 32 bypass grafts. The average radial artery length was (20.20±2.06) cm. The average internal diameter of the proximal end was (2.41±0.28) mm, as the average inner diameter of the distal end was t (2.28±0.42) mm. These examinations combined with Allen’s test and angiography indicated that the radial arteries were selected with good patency and suitable for high-flow bypass surgery. In this study, the bypass technique had a 100% success rate. Postoperative and follow-up imaging findings demonstrated graft vessel patency. None of the patients had suffered ischemic stroke due to radial artery spasm. The muscle strength of forearm and wrist showed no drop compared with that before operation. Postoperative 4 cases showed injury symptoms of lateral forearm cutaneous nerve and superficial branch of radial nerve, and relieved within 3 months. Conclusions Application of extraction technology with radial artery in cerebrovascular bypass surgery was demonstrated good safety and efficacy. This technique with high-flow cerebrovascular bypass surgery has wide application prospects in the cranial base tumors, complex cerebrovascular disease and other fields.
