Background: The transradial approach is associated with low complication rates. The D Stat Radial vascular closure system offers hemostatic pressure locally at the puncture site with residual venous flow.
Methods: We prospectively included 113 consecutive patients presenting between August 2006 and December 2006. Diagnostic coronary procedures were performed using 4 Fr or 5 Fr sheaths, while 6 Fr devices were used for PCI. In every case at least 5.000 IU heparin was given. Compression with the retention strap was planned for approximately 3 hours before the pad was fixed using a medical strip. All data were entered into a database after a two-dimensional ultrasound examination study of the puncture site.
Results: The mean age was 65 years (+/-SD 10.3), with 62% being male. Patients presenting with acute coronary syndrome amounted to 6.2%, where 5r F sheaths were usually used with these patients (64.6%). PCI was carried out in 21.2% of cases. The system was applied successfully in all patients. The mean duration of compression was 4.6 hours (+/-SD 1.4). Bleeding after removal of the system occurred in 18.6% of cases, which resulted in prolonged compression in 17.7%. A hematoma >5 cm was seen in 4.4% of the sample. Ultrasound examinations revealed closure of the radial artery in 6.2%.
Conclusions: We conclude that this new device operates efficiently, but bleeding occurred in 18.6%. Compression time should be extended to 6 hours.
