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

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. 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. Hematoma occurred more frequently in the sandbag group. Hematoma of
