Comparison of controlled pressure belt -allowing mobilityto sandbags after percutaneous coronary intervention: pilot study

OBJECTIVES
We aimed to investigate the efficacy and safety of a belt mechanism (anjiobelt), which we developed recently and patented, which allows mobility after coronary operations and the application of adjustable pressure to the femoral artery.

STUDY DESIGN
Between October 2012 and April 2013, 189 consecutive patients undergoing percutaneous coronary intervention electively or due to acute coronary syndrome were enrolled. There were 96 patients in the sandbag group and 93 patients in anjiobelt group. Manual compression was applied to the femoral artery until reaching primary homeostasis. Then, a 4-5 kilogram sandbag or anjiobelt was placed. Mobilization was allowed in case of need in the anjiobelt group. Twenty-four hours after the procedure, superficial bruising in the femoral region, hematoma, pseudo-aneurysm, and arteriovenous fistula, as femoral artery complications, were noted using Doppler ultrasound.

RESULTS
Hematoma occurred more frequently in the sandbag group. Hematoma of <1 cm developed in 52 patients with sandbag and in 25 patients with anjiobelt (p<0.0001), while hematoma of 1-5 cm developed in 5 patients with sandbag and in 3 patients with anjiobelt (p<0.0001). Femoral artery pseudoaneurysm was seen in 4 patients (2 with anjiobelt, 2 with sandbag; p=0.975).

CONCLUSION
Anjiobelt significantly reduces the incidence of hematoma in comparison to conventional sandbag in patients undergoing percutaneous coronary intervention. Other complications of the femoral region in terms of efficiency and safety appear to be similar to those observed with sandbag. The main problems occurring in these patients due to absolute immobilization have been eliminated with the anjiobelt.
