Angioscopy has been used in the superficial femoral artery for many ye
ars, as well as in the control of vascular surgery procedures. It is m
ore reliable than angiography, which often misses such features as int
imal flaps, residual valves in ''in situ'' vein bypasses or persisting
thrombus after embolectomy. As fluid irrigation allows visualization
of the iliac arteries, and as smaller atraumatic fibres allow safe vis
ualization of the tibial arteries, new fields are opened for the use o
f angioscopy in peripheral vascular disease. This technique has been p
roved to be useful: (1) as a diagnostic tool, (2) as a control device
in new endovascular procedures (percutaneous angioplasty, atherectomy
and stents), and (3) as a therapeutic tool (thromboembolectomy, simpli
fication of bypass procedures). In a modern operating room, angioscopy
does not replace angiography, but these two imaging techniques are co
mplementary, as they help the surgeon to provide the patients with a l
ess invasive vascular surgery.
