Descrição

INTRODUCTION: Complications at the site of vascular access are the most common adverse events in cardiac catheterization. The use of small gauge catheters may reduce this risk and allow earlier ambulation, the main disadvantage according to some authors being inferior image quality. The aim of our study was to evaluate the safety and image quality of 4 French diagnostic catheters. METHODS: We performed a retrospective study of 1656 patients who underwent diagnostic cardiac catheterization with 4F catheters via the femoral artery between January 2006 and December 2007, and analyzed the complications during and immediately after the procedure. The quality of the films was assessed in 125 consecutive patients from this group, who were also followed up on average one month after hospital discharge. RESULTS: Cardiac catheterization with 4F catheters was technically possible in all cases. Patients were able to ambulate and were discharged from hospital on average four and six hours respectively after the procedure. Complications during or immediately after the procedure occurred in 5.8% of cases. In the subgroup with clinical follow-up, there was minor bleeding at the access site in 16.4% and hematoma in 14.4%; in the latter group, only one patient had major hematoma requiring therapeutic intervention. No other major complications were recorded and the patients resumed their daily activities on average 7 days after discharge. Image analysis revealed that most of the films were of good quality. Conclusion: The use of 4F catheters for diagnostic cardiac catheterization via the femoral approach enables rapid hemostasis and early ambulation, with a low incidence of complications at the access site. This type of catheter provides good quality images and there were no problems in their handling. 4F catheters are therefore a good option to consider for cardiac catheterization, especially when no therapeutic procedures are expected.
