Sheaths
The use of radial artery access for coronary intervention has grown in popularity worldwide. Its use reduces significantly vascular access complications when compared to the more established femoral artery access. Use of the radial artery however, is prone to development of spasm which can be painful to the patient and in severe instances prevent procedure completion. The use of radial sheaths is designed to minimise this complication. The Terumo radial sheath is a hydrophilic outer sheath with a side arm and comes with its own dilator. I have used both the 5F and 6F sizes. The pack comes with its own needle and plastic sheath and a hydrophilic wire. The recommended technique used for the Terumo kit is the 'back wall' puncture. As someone who is used to an 'open needle' technique for radial artery punctures, this was not initially intuitive but after 3 successful attempts I was happy to use the kit.

An excellent radial sheath that is let down by a bulky wire that is difficult to torque.
