Small vessel leg angiography for distal vessel bypass grafts

Abstract

To improve visualization of the small vessels for distal bypass grafting, arteriograms of the lower extremity were obtained in 187 patients by use of active warming of the extremities, selective distal positioning of the catheter for contrast agent injections, and intraarterial administration of tolazoline. With these techniques, satisfactory visualization was obtained for planning of operation, and in only one patient was an intraoperative arteriogram necessary before bypass grafts were placed.

Outcome of infrainguinal arterial reconstruction in women

“…All patients underwent angiography with specific attention to visualization of the distal extremity arteries according to techniques described previously by our radiology group, including selective catheterization, delayed filming, and use of intraarterial vasodilators. 15 Absence of a suitable distal target vessel was defined by the presence of small, unnamed contrast-filled vessels in the foot and distal leg, without contrast filling of the named tibial or pedal Vessels.…”

Calf Vessel Runoff Assessment in Patients Undergoing Femorodistal Bypass

“…Performing the contrast injection with the catheter in the ipsilateral external iliac artery will direct the bolus to that limb and considerably improve the distal views. Occasionally, it can be valuable to perform an antegrade puncture and catheterise the most significant infrainguinal run off vessel directly [29]. Vasodilation with either intraarterial glycerine trinitrate (100 mg) or papaverine hydrochloride (30 mg) or reactive hyperaemia may be used to further optimise distal views [30,31].…”
