The Feasibility of Percutaneous Transradial Coronary Intervention for Saphenous Vein Graft Lesions and Comparison with Transfemoral Route

Methods: We examined 115 consecutive patients undergoing SVG PCI between January 2003 and December 2005 and compared the radial (51 patients) and femoral (64 patients) approaches. Results: Baseline demographics, lesion location, and clinical indication were similar in both groups. GpIIbIIIa inhibitor usage was high in the radial group (78.4% vs. 53.1%, P < 0.01). Angiographic success was similar in both groups, 96% in the radial group vs. 96.8 in the femoral. Total fluoroscopy time (18.59 +/- 12.23 vs. 20.45 +/- 12.9), total procedure time (52.1 +/- 29.5 vs. 43.90 +/- 23.31 min), and the use of total contrast volume (357.0 +/- 174.0 vs. 346.0 +/- 157.0 ml) were similar in the radial and femoral groups, respectively. In-hospital MACE (radial: 2 MI [4.0%] vs. femoral: 1 death [1.6%] and 7 MI [11.0%], P < 0.01) were similar in both groups. Access site vascular complications (radial: 2 [4.0%] vs. femoral: 10 [11.0%], P < 0.001) were significantly less in the radial group. Conclusions: The transradial approach for SVG PCI is feasible, safe, and as quick as the femoral approach. Procedural success is high with similar radiation and contrast exposure. In-hospital MI in the femoral group is high because of more-unstable patients. However, there are significantly lower vascular complications despite high use of platelet inhibitors in the radial approach. (J Interven Cardiol 2009;22:336-340).
