Direct stent implantation without predilatation through 5 French guiding catheter following transfemoral coronary angiogram: a feasibility study.
Direct stenting (DS) is accepted as reducing procedural cost and duration and 5 Fr guiding catheters as lowering peripheral vascular complications. We aimed to evaluate the feasibility and safety of both strategies. We retrospectively studied 150 consecutive patients treated with DS strategy using a 5 Fr femoral approach. A need for 6 Fr devices or balloon predilatation defined 5 Fr DS failure. Procedural success was defined as good angiographic result (residual stenosis < 30% and TIMI flow 3) without ischemic complications. A total of 161 out of 174 lesions were elected as suitable for DS. The success rate of 5 Fr DS was 87.6% (141/161 lesions). The procedural success rate was 92% (138/150 patients). The angiographic success rate was 96.3% (155/161 lesions). Other complications were six non-Q-wave MI and one repeat angioplasty for acute in-stent thrombosis. Only one major peripheral vascular complication occurred. Direct stenting through 5 Fr guiding catheters in selected lesions is safe and effective with a low incidence of peripheral arterial complications.
