Hemostasis after Trans Radial Intervention Division of Cardiology, Department of Internal Medicine Dongguk University Gyeongju Hospital Deuk-Young Nah, MD, PhD Hamon M, et al. AHA 2006 The primary goals of TRI Easy Hemostasis and Early Ambulation Two methods of hemostasis after TRI 1. Conventional compression 2. Patent hemostasis Hemostasis Manual Compression / Gauze / Coban Hemostasis HemoBand pressure pad The ideal hemostasis after TRI Ensure adequate hemostasis without compromising the integrity of radial artery circulation The ideal hemostasis after TRI Hemostasis Radistop Compression Assist Device Hemostasis RadStat Radial Artery Compression Device (Merit Medical) Hemostasis Terumo TR Band Hemostasis HEMO-STOP Transradial Transradial Compression Bracelet Aids Hemostasis This bracelet is designed to obtain a stable compression of the radial artery, which will allow an uninterrupted flow of blood sufficient to protect the vascular system, while assuring adequate compression to avoid hematoma and encouraging prompt hemostasis. The device will be released in April For more information: Hemostasis Midforearm Hematoma Radial artery occlusion (=RAO) 1.Incidence is 1-5% 2.95% of RAO occlusion are asymptomatic Factors in RAO 1.Vasospasm 2.Inadequate anticoagulation 3.Prolonged occlusive pressure 4.Radial Artery damage Access, Prolonged canulation Sheath-to-artery ratio > 1 Excessive compression pressure Radial artery occlusion 1.Thrombosis initiated by flow abnormality during the procedure. 2.Thrombosis propagated by occlusive hemostatic pressure 3.Organizing thrombosis leading to fibrotic obliteration Radial artery occlusion J INVASIVE CARDIOL 2009;21:101104 Radial artery occlusion Conclusions 1.Hemostasis after TRI is effective, cheap, and easier compared to hemostasis after femoral or brachial intervention. 2.Patent hemostasis to prevent radial artery occlusion is very important.
