- Discussion:
- perform arteriography for any projectile that passes thru anteromedial
quadrant of the thigh;
- because of the size of
common femoral artery, the femoral arteriogram
is the easiest to obtain;
- when placing the Cournand needle in common femoral artery in groin,
placement into a tributary must be avoided;
- when properly placed, there will be a return of blood flow with full
arterial pressure;
- to evaluate injury to superficial or
deep femoral artery, only small
amount of dye (25 to 30 ml) needs to be rapidly hand injected,
and the radiograph is obtained on completion;
- when vessels in question are the
popliteal or shank arteries, the
volume of dye is increased (50 ml) and the film is delayed 3 to 5
seconds after completion of injection;
- thin walled, 18 gauge, 5.23 cm Cournand disposable needle is inserted
either proximal (as in the common femoral artery for superficial
femoral artery studies) or distal (as in retrograde
axillosubclavian artery studies) to the area of suspected injury;
- depending on artery being evaluated, single rapid hand injection of
25 to 50 ml of 30 % meglumine diatrizoate dye is carried out
and a single radiograph obtained;

Vascular proximity: is it a valid indication for arteriography in
asymptomatic patients
