A new vascular closure device for the transradial approach: the D Stat Radial system.
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.
