Introduction:

Multiple vascular compression aimed for transradial access have been developed. We aimed to compare the time required to achieve hemostasis in three different radial vascular compression devices.

Methods:

ST and non-ST elevation MI, unstable and stable angina as well as diagnostic coronary angiograms patients with transradial vascular access (TVA) in 2 centers were enrolled between June 2010-November 2010. Patients were divided according the TVA compression device (TAVCD) used. Group I received TR Band(tm) (Terumo, Tokyo, Japan), Group II received Neptuno(tm) (Biotronik, Berlin, Deutschland) and Group III received Finale(tm) (Merit Medical, South Jordan, UT).Patients were evaluated immediately after TVACD implantation and 24 hour post-procedure follow up.

Results:

60 patients were enrolled in this observational study (Group I = 22 patients; Group II = 18; Group III = 20). All patients demonstrated evidence of radial pulse after hemostasis. 28% developed a superficial hematoma (Group I, 31%; Group II, 30%; Group III, 22%). Pain at the access site was uncommon among patients in both immediate and follow-up evaluations, however, 3% (Group I and II) presented paresthesia immediately following the procedure that resolved by the 24-hour evaluation.

Conclusion:

In our study, all three evaluated radial compression devices successfully achieved hemostasis regardless of the slight alterations of mechanism, yet similarity in aim of non-occlusive compression. Group I (TR band) had a slight increase in compression time recorded but all groups required an approximate three hours to display no evidence of bleeding. None of the patients in the study presented major vascular complications. We consider that further investigation of radial compression devices as compared to manual compression are necessary to evaluate their advantages and may further simplify the procedure
