ABSTRACT
Vascular trauma to the extremities is less frequently lethal and more commonly penetrating
than thoracoabdominal trauma. Arteriography is indispensable in the evaluation of
stable patients with hard physical findings or a positive finding on one of a growing
variety of noninvasive diagnostic modalities. However, it is not indicated in unstable
patients with obvious vascular injury and it is controversial when used in patients
with soft findings or simply a penetrating injury in close proximity to a major vascular
structure. Arteriography provides access for an increasing array of endovascular treatment
options. Embolization can effectively halt bleeding from small- and medium-sized arterial
branches where preservation of flow is not crucial. Covered stents and stent grafts
can successfully treat lesions in larger arteries where flow must be preserved, but
these are off-label uses where the short-term benefit of avoiding difficult or hazardous
surgical access must be weighed against disappointing long-term patency rates, especially
when a young patient is involved. Intra-arterial vasodilators can be very useful in
patients with critical ischemia due to arterial spasm and local low flow states resulting
from severe extremity injuries.
