Transit-Time Flow Measurement in Evaluating the Graft Vessel Blood Flow During Coronary Artery Bypass Grafting
Coronary artery bypass grafting is a pivotal surgical intervention for the management of end-stage multi-vessel coronary artery disease.The intraoperative patency of the graft vessels is critical,as it directly influences the surgical outcome,postoperative safety,and long-term quality of life of the patient.Transit-time flow measurement(TTFM)has emerged as a valuable tool due to its ease of use and minimal invasiveness.TTFM is frequently employed to assess the efficacy of graft vessel perfusion during surgery,enabling the detection of abnormal graft vessel blood flow and providing an indication of graft patency.This,in turn,can enhance surgical quality,reduce the incidence of long-term graft occlusion,and improve patient prognosis.This review offers a comprehensive overview of the clinical application of TTFM in coronary artery bypass grafting,focusing on its utility in evaluating graft vessel blood flow and its implications for graft vessel patency.
