Abstract:
Background and objective: With recent advances in technology and miniaturization of equipment, the trans-radial approach has currently been advocated as an alternative method for coronary angioplasty. We tried to evaluate the feasibility of trans-radial coronary intervention (TRCI). MATERIALS AND METHODS: 138 Allen-positive cases (159 lesions) underwent TRCI with currently available devices. Mean age was 60.8 + 9.2 years and 67% were men. Clinical diagnoses were AMI in 49, unstable angina in 48, stable angina in 28, OMI in 9 and 4 cases of restenotic lesions. RESULTS: Technical success was achieved in 124 cases (89.9%). Among the 124 successful cases, left and right radial arteries were used in 93 cases (110 lesions) and in 31 cases (35 lesions), respectively. The size of the guiding catheter used for TRCI was 6 Fr in 100 cases (80.7%), 7 Fr in 21 cases (16.9%), and 8 Fr in 3 cases (2.4%). Stent implantation and rotational atherectomy were successfully performed in 75 cases (86 lesions) and 10 cases (12 lesions), respectively. The reasons of failure were puncture failure in 2 cases, guiding failure in 6 cases, guide-wire crossing failure in 4 cases who had chronic total occlusion, and suboptimal results in 2 cases. Major cardiac complications occurred in 3 cases, one case of each cardiac death, nonfatal myocardial infarction and coronary artery perforation. No major entry site complications were seen with only non-ischemic radial artery occlusions in 3 cases (2.8%). CONCLUSION: TRCI is feasible with currently available devices and is safe with a relatively acceptable procedural success rate and low complications.
