摘　　要：To the Editor:The main cause for failed complex coronary lesions especially chronic total occlusion(CTO)revascularization is the inability of device delivery due to the lack of adequate guide support or the failure of guidewire manipulation,such as unsuccessful externalization of the retrograde guidewire and incapable reentry into the true lumen.Some devices and techniques have been used to deal with these problems,and the guide catheter extension system(GCES)is one of the effective solutions.
