[Treatment of coronary bifurcation lesions with 6F-guiding catheter by transradial approach].

OBJECTIVE: To investigate the feasibility and safety in treatment of coronary bifurcation lesions with 6F-guiding catheter by transradial approach.

METHODS: Clinical data of 1258 patients who were treated with 6F-guiding catheter by transradial approach from Oct. 2003 to Feb. 2007 were reviewed. The most common approach in the treatment of bifurcations was one-stent technique on the main branch; if the side branch was large enough and the lesion was involved in the ostium and proximal part of side branch, two-stent technique was used.

RESULT: Of 295 bifurcation lesions, 204 were originally planed to be treated by one stent; but finally 2 side branches were provisional stented due to dissection in this group. Ninety-one cases were planed to use double-stent technique: 73 with crushing stent (46 step crushing, 24 modified balloon crushing, 3 reverse crushing), 5 with T-stent, 3 with Cullote-stent, 5 with modified V-stent, 5 with step kissing stent. There was no acute myocardial infarction or death occurred but 1 case was complicated with cardiac tamponade secondary from coronary perforation.

CONCLUSION: The treatment of coronary bifurcation lesions with 6F-guiding catheter by transradial approach is a feasible and safe procedure.
