The protocols of the manipulation duration and the effect for TRA pPCI and TFA pPCI procedures were respectively compared, including the time of transradial artery puncture and the rate of puncture success at first time ; the time of guiding catheter engaging into target coronary ostium; the rate of patence in infarct related artery (IRA); total duration of manipulation and the successful rate.The incidence of complications such as bleeding, vessel injury,thrombi and embolism as well as the average stay of hospitalization between two groups was compared. The status and the incidance of vessel spasm were observed and the effect of medicine administration to prevent from and relieve the vascular spasm was evaluated. The time of Allen’s test before and after TRA pPCI , the inner diameter and the peak of blood velocity of the right and left radial artery were investigated with color Doppler vessel echography as well as the complications of radial artery were followed up 1 month after TRA pPCI procedure. Results Two cases in every TRA pPCI and TFA pPCI groups were crossed over each other because procedure of the transradial or transfemoral access was failure. One handred and six vessels (48 vessels in LAD,22 vessels in LCX and 36 vessels in RCA) associated with 28 vessels of total occlusion in TRA pPCI group and 102 vessels (51 vessels in LAD,18 veesles in LCX and 33 vessels in RCA) with 24 vessels in total occlusion in TFA pPCI group were angioplasticized . The successful rates of the first time puncture in access artery, the re patence IRA and pPCI were similar in TRA pPCI and TFA pPCI groups ( 93.4% vs 96.1% ;100% vs 100%; 96.2% vs 97.1% , P >0.05 ). There were no significant diffierence in the average time of puncture time of access artery ,engaging in target vessels of guiding catheters and the total procedure of PCI between the two groups ( 1.3 ±0.3s vs 1.2 ±0.3s ; 6.0 ±1.6min vs 5.8 ±0.9min ; 49.2 ±24.1min vs 46.5 ± 26.4min , P >0.05 ). The access artery complications such as bleeding ,hematoma and embolism as well the veneous thrombosis in TFA pPCI group were much more than those in TRA pPCI group(p< 0.01 ). Although slight artery spasm of 4.7% cases in TRA pPCI group was happened during the procedure of PCI , the procedure had being continued after administration of medicine to release the spasm. The time of Allen’s test ,diameter and the systolic velocity of blood in daul radial arteries were no significant change before and after pPCI.Conclusions The duration and effect by TRA pPCI for AMI with stable hemodynamics was similar to TFA pPCI. The complications such as of bleeding,vessel injury, thrombi and embolism by TRA pPCI were few, and it was unnecessary to discontinue the anticoagulation medicine. TRA pPCI might be selected as a access vessel for pPCI in AMI patients with stable hemodynamics.展开更多

This study evaluated feasibility of transradial PCI （TRI） and compared the immediate and followup results with transfemoral PCI （TFI） in bifurcations. Methods One hundred and thirty-four consecutive patients with bifurcations were treated with PCI in our hospital from April 2004 to October 2005. Of these, there were 60 patients （88 lesions） in TRI group and 74 patients （101 lesions） in TFI group. Bifurcations type was classified according to the Institut Cardiovasculaire Paris Sud Classification. Results TRI group had smaller stent diameter （（3.06±0.37） mm vs （3.18±0.35） mm, P=0.023） and postprocedural in-stent minimum lumen diameter （（2.62±0.37） mm vs （2.74±0.41） mm, P=0.029） than TFI, but there were not significant differences in in-stent subacute thrombosis rate （0% vs 1.0%, P=0.349）, target lesion revascularization （TLR） （0% vs 1.0%, P=0.349） following procedure and thrombosis （2.3% vs 1.0%, P=0.482）, in-stent restenosis （12.5% vs 10.9%, P=0.731）, in-segment restenosis （17.0% vs 14.9%, P=0.681）, TLR （10.2% vs 13.9%, P=0.446） and TLR-free cumulative survival rate （89.8% vs 86.1%, P=0.787） at seven months followup. No death was reported in the two groups. Conclusion Transradial intervention is feasible and appears to be as effective and safe as transfemoral PCI in treatment of true bifurcational lesions.展开更多
