Objective:
To assess stent implantation without previous dilation with a conventional balloon catheter to treat coronary artery obstructions, by using low profile guiding catheters and the transradial approach.
Methods:
The transradial approach is attractive due to the possibility of avoiding the trauma caused by the balloon, its shorter time of performance, reduced exposure to radiation, and the use of lower quantities of contrast medium than those usually required in this type of procedure.
Results:
The initial experience of direct stent implantation with low profile guiding catheters and the transradial approach was analyzed in 45 patients, whose mean age was 65 years. All procedures were successful, with no major complications in the in-hospital phase.
Conclusion:
The results obtained with the population studied proved that the transradial approach is safe, effective, and has very few risks of complications.
