ABSTRACT
Objective To summarize the experience of applying transradial sheathless technique in treat-ment of bifurcation coronary lesions. Methods The clinical data on 39 patients with bifurcation coronary lesions who received transradial PCI using sheathless guide catheter produced by ASAHI or self-made sheathless guide catheter were retrospectively analyzed. Passing ability of sheathless guide catheter, success rate and complications of PCI were observed.Results There were 10 patients with left main bifurcation lesions, 29 left anterior descend-ing branch and diagonal branch bifurcation lesions. 33 patients were treated using sheathless of 7.5 Fr and 6 were treated by self-made sheathless guide catheter.PCI achieved expected goal.No catheter placement related complica-tions, cardiovascular or cerebrovascular events were observed in 39 patients in their hospital stay. Conclusions Transradial sheathless technique can be applied in of coronary lesions. Sheathless of 7.5 Fr is easy to use and has perfect passing ability.Sheathless guide catheter is effective,safe and highly practicable.Both procedures are worth of clinical application.
ABSTRACT
Objective To summarizes the experiences and technique of complex transradial percutaneous coronary intervention (PCI) using sheathless guide catheter (Sheathless Eaucath, ASAHI) for 60 patients with coronary heart disease. Methods Retrospectively analyzed the data from 60 patients received PCI using sheathless guide catheter. Results PCI were performed on a total of 60 patients with complex lesions. Angiographic success was achieved in 95.0%and failed in three patients with CTO. 7 patients were with left main lesions, and 32 patients were with bifurcation lesions(including 7 patients with left main lesions and 2 patients with CTO), and 13 patients were with CTO, and the other 17 patients were with tortuous and calcified lesions. Sheathless guide catheters of 7.5Fr were used for PCI in all patients, and all catheters successfully passed through the radial artery and were put in place. No other vascular complications associated with the use of the catheter occurred. Sheathless guide catheters were respectively JL(8 patients), PB(2 patients), AL(2 patients), and JR(1 patient) in 13 patients with CTO, and were respectively JL(8 patients), JR(6 patients), SPB(2 patients), AL(1 patient) in 17 patients with tortuous and calcified lesions. JL or JR were used in all 32 patients with bifurcation. Conclusions Use of the Sheathless of 7.5 Fr is safe and feasible, and allows complex interventions to be undertaken transradially with a high success rate.
