Our aim was to reduce motion artefact during radiographic angiography and MRI of the lower limbs. The legs were immobilized using a bead bag with a filtered closeable valve. Air was removed by suction and the bag moulded into a rigid restraint. The bead bag is an effective, well tolerated and easily used immobilization device that is suitable for use in radiological imaging.

Transjugular intrahepatic portasystemic shunt (TIPS) is now considered as an option for the control of intractable variceal bleeding1. The high incidence of stenosis and occlusion (50 per cent significant stenosis at 6 months2) favours its use as a bridge to more definitive therapy such as surgical shunting or orthotopic liver transplantation (OLT). The specific difficulties presented to the surgeon by the metal stent have not been considered, although they have been reported anecdotally'. The surgical comp!ications of TIPS insertion have been reviewed.
