Abstract:
OBJECTIVE:To summarize the application experience and clinical effect of radial artery in total arterial coronary revascularization (TAR) in elderly patients.
METHODS:Retrospectively analyzed the clinical data of patients who underwent TAR at the University of Hong Kong Shenzhen Hospital from July 1, 2020 to May 30, 2022. Patients were divided into ≥ 65-year-old group and < 65-year-old group according to age. The radial artery blood flow, diameter, intimal integrity and Allen test were evaluated by ultrasound before operation. The distal ends of radial artery were collected for pathological examination during operation. Coronary artery CT angiography (CTA) was examined postoperatively and follow up. The safety and reliability of ultrasonic assessment of radial artery and application of radial artery in elderly patients with TAR were summarized and analyzed.
RESULTS:A total of 101 patients received TAR, including 35 cases aged ≥ 65 years old, 66 cases aged < 65 years old; 78 cases used bilateral radial arteries, and 23 cases used unilateral radial arteries. 4 cases of bilateral internal mammary arteries. All the proximal ends of the radial artery were anastomosed to the proximal end of the ascending aorta, 34 cases were performed of "Y" grafts, and 4 cases were sequential anastomoses. There was no in-hospital death and perioperative cardiovascular events. Perioperative cerebral infarction occurred in 3 patients. 1 patients was reoperated for bleeding. Intra-aortic balloon pump (IABP) assistance was used in 21 patients. Poor wound healing occurred in 2 cases and healed well after debridement. Follow-up of 2 to 20 months after discharge showed no internal mammary artery occlusion and 4 radial artery occlusions; no major adverse cardiovascular and cerebrovascular event (MACCE) occurred, and the survival rate was 100%. There was no significant difference in the above perioperative complications and follow-up endpoints between the two age groups.
CONCLUSIONS:By adjusting the order of bypass anastomosis and optimizing the preoperative evaluation method, radial artery combined with internal mammary artery can obtain better outcome early in TAR, and can be safely and reliably applied to elderly patients.
