Study: Terumo TR Band™ Hemostasis Device Reduces Radial Artery Occlusion by 56%

A new study, conducted by Dr. Samir B. Pancholy of Mercy Hospital in Scranton, Pennsylvania, shows that the concept of "guided compression" in transradial procedures can reduce radial artery occlusion by 56%, especially when facilitated by the use of the TR Band™ Hemostasis Device.
While infrequent (in the single digits), radial artery occlusion is a discouraging complication of radial artery access.
Although it is usually benign for the patient, it precludes future radial access. For example, if the radial artery occludes after a diagnostic catheterization, any subsequent PCI procedures must be done via the femoral artery.

But there are a number of methods for achieving hemostasis in a radial procedure. Pancholy looked at data from his own lab and saw that patients on whom he had used the TR Band, as opposed to the commonly-used HemoBand, had significantly lower rates of radial artery occlusion. So Dr. Pancholy devised a randomized clinical study to test the efficacy of the TR Band in preventing radial artery occlusion.
500 consecutive patients undergoing transradial catheterization were prospectively enrolled in the study. 250 consecutive patients received hemostasis by application of HemoBand (Group I) and the next 250 patients received hemostasis using the inflatable TR band (Group II). Radial artery patency was studied the time of application of the hemostasis device, at 30 minutes, 60 minutes and at 24 hour and 30 days using Barbeau’s test.
The results were that 28 patients in Group I (11.2%), developed evidence of early occlusion (at 24 h), compared to 11 patients (4.4%) in Group II (P<0.005).>
