          Translated abstract

          Coronary angiography and percutaneous treatment of stenotic lesions have expanded in the last few years, due to availability of better diagnostic equipment. The femoral technique applied to this aims has prevailed, considering its efficacy, safety and wide acceptance. Since the beginning of this decade, an alternative access has been developed, in relation to miniaturization of the required elements to perform coronary diagnostic and therapeutic procedures. This new radial artery access is supported by multiple reports from many centers around the world that are increasingly using the technique. With this access it is possible to perform all the regular procedures done regularly through the femoral route. This case report illustrates a coronary angiography study through the radial access, followed by a stent implantation, through the same route.

          A randomized comparison of percutaneous transluminal coronary angioplasty by the radial, brachial and femoral approaches: the access study.

          This study sought to compare procedural and clinical outcomes of percutaneous transluminal coronary angioplasty (PTCA) performed with 6F guiding catheters introduced through the radial, brachial or femoral arteries. Transradial PTCA has been demonstrated to be an effective and safe alternative to transfemoral PTCA; however, no randomized data are currently available. A randomized comparison between transradial, transbrachial and transfemoral PTCA with 6F guiding catheters was performed in 900 patients. Primary end points were entry site and angioplasty related. Secondary end points were quantitative coronary analysis after PTCA, procedural and fluoroscopy times, consumption of angioplasty equipment and length of hospital stay. Successful coronary cannulation was achieved in 279 (93.0%), 287 (95.7%) and 299 (99.7%) patients randomized to undergo PTCA by the radial, brachial and femoral approaches, respectively. PTCA success was achieved in 91.7%, 90.7% and 90.7% (p = NS) of patients, with 88.0%, 87.7% and 90.0% event free at 1-month follow-up, respectively (p = NS). Major entry site complications were encountered in seven patients (2.3%) in the transbrachial group, six (2.0%) in the transfemoral group and none in the transradial group (p = 0.035). Transradial PTCA led to asymptomatic loss of radial pulsations in nine patients (3%). Procedural and fluoroscopy times were similar, as were consumption of guiding and balloon catheters and length of hospital stay ([mean +/- SD] 1.5 +/- 2.5, 1.8 +/- 3.8 and 1.8 +/- 4.2 days, respectively). With experience, procedural and clinical outcomes of PTCA were similar for the three subgroups, but access failure is more common during transradial PTCA. Major access site complications were more frequently encountered after transbrachial and transfemoral PTCA.

            Percutaneous transradial artery approach for coronary stent implantation.

            A new approach for implantation of Palmaz Schatz coronary stents is reported. We describe the technique and rationale of coronary stenting with miniaturized angioplasty equipment via the radial artery. This technique is illustrated in three patients. One patient underwent Palmaz Schatz stent implantation for a saphenous vene coronary bypass graft stenosis, the second patient for a restenosis in the anterior descending coronary artery after atherectomy, and the third patient for a second restenosis after balloon angioplasty in the circumflex coronary artery.

              Left radial approach for coronary angiography: results of a prospective study.

              Although radial approach has been shown to be feasible for coronary angiography, angioplasty, and even stent placement, there have been no prospective evaluations of ease and safety of left radial approach for coronary angiogram. We examined procedural duration and success as well as complications in 415 consecutive patients. Radial artery occlusion was assessed immediately post-procedure and at 2 month follow-up using echo-Doppler measurements. Procedure failure rate was 9%, mean time for sheath insertion was 4.7 +/- 4.7 min, and mean procedure duration was 19.1 +/- 8.2 min. No major complications occurred. Asymptomatic radial artery occlusion was noted in 71% of the first 49 patients, decreased to 24% in the next 119 receiving 2,000-3,000 units of heparin, and to 4.3% in the last 210 receiving 5000 (p < 0.05). Comparison with the femoral approach in the same laboratory suggested that the radial approach took longer, but provided similarly high-quality results without great difficulty in coronary cannulation. Hence, the left radial approach for coronary angiography (with heparin administration) allows immediate ambulation and may be especially useful for outpatients and when the femoral approach is not possible.
