Recommendations:
- A long sheath (20-23 cm) allows free movement of the guide,
without making contact with the radial artery wall. This will reduce spasm during the
procedure, especially at the beginning of the learning curve, during which more guide
manipulations and exchanges may be required. Guide manipulations are easier.
The
disadvantage of a long sheath is a more difficult removal in case of radial artery spasm.
Therefore a sheath with a side port, to allow injection of spasmolytics, is recommended.
Sheaths with a lubricant coating or with side holes are being developed.
Many experienced transradial angioplasters are also using short sheaths with excellent
results. Some recommend the use of ultra-short sheaths (5 cm) to facilitate sheath removal
if the radial artery becomes spastic.
