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

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 2010.

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

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.
