Laser recanalization was introduced and developed in Britain in the 19
80s in an attempt to deal with the limitations associated with the con
ventional technique of percutaneous transluminal angioplasty (PTA), Si
nce then, the use of this technique has decreased. This paper reports
the findings of a comprehensive literature survey and interviews with
a representative sample of British interventional radiologists on the
reasons for this decline, and suggests the likely future direction for
this technology. It has been determined that the main reasons for the
decline are improvements in conventional guidewire and catheter techn
ology, the high cost of the laser system, and the lack of evidence of
any improvement in results compared with conventional PTA, However, de
spite current disenchantment, the majority of radiologists questioned
felt that lasers could have a future role to play and that development
of these systems should continue.
