目的:观察经尺动脉途径介入治疗冠心病术后半年平板运动试验对心功能的评估结果,比较经尺动脉途径和经桡动脉途径介入治疗的可行性。方法:在10例患者中应用经尺动脉途径成功7例,其中5例为冠脉造影,2例为支架植入,与经桡动脉途径病例105例进行比较,并对两组患者中接受经皮腔内冠状动脉成形术(percutaneoustransluminalcoronaryangioplasty,PTCA)及支架植入者进行随访,同时应用活动平板运动试验评估患者心功能情况。结果:经桡动脉途径与经尺动脉途径穿刺及导管操作的平均时间犤冠状动脉造影(60±30)min,PCI(83±24)min犦差异无显著性意义。冠状动脉造影及支架植入的成功率经两种途径差异无显著性意义。7例患者中没有并发症发生,术后随访平板运动试验评价的心功能均得到改善。结论:尺动脉可作为另一个可行的冠状动脉诊断和治疗途径,同时可保留桡动脉用于做外科冠脉搭桥。经尺动脉途径介入治疗冠心病后通过活动平板运动试验检测发现,此种术式能显著改善患者术后的心功能。
OBJECTIVE: To observe the evaluation of cardiac function by six-month treadmill exercise test after interventional ulnar artery interventional therapy through coronary angiography, and to compare the feasibility of interventional therapy with ulnar artery and radial artery. Methods: Seven patients were successfully treated with ulnar artery in 10 patients. Among them, 5 were coronary angiography, 2 were stenting, and were compared with transradial route in 105 patients. Percutaneoustransluminal coronary artery angioplasty (PTCA) and stent-graft were followed up, and treadmill exercise test was used to evaluate the cardiac function. Results: The average time of transradial and transection approach and catheterization was no significant difference between coronary angiography (60 ± 30) min and PCI (83 ± 24) min 犦. The success rate of coronary angiography and stent implantation by two ways no significant difference. No complications occurred in 7 patients, and heart function assessed by the treadmill exercise test was improved after follow-up. Conclusion: The ulnar artery can be used as another viable approach to diagnosis and treatment of coronary artery. Radial artery can be reserved for surgical bypass. Interventional treatment of coronary artery disease by the ulnar artery pathways through the treadmill exercise test found that such surgery can significantly improve the patient’s cardiac function.
