Temporary vascular shunting used as a damage control adjunct in management of wartime extremity vascular injury does not lead to worse outcomes. Benefit from TVS is suggested, but not statistically significant. Injury specific variables of venous ligation, associated fracture, and penetrating blast mechanism are associated with amputation. Amputation-free survival after vascular injury in Operation Iraqi Freedom is 79% at three years. Further studies to statistically define any possible benefits of TVS are needed.

Femoropopliteal vascular injury remains a significant reality in modern warfare. Femoral injuries appear more prevalent than those in the popliteal region. Early results of in-theater repair are comparable with contemporary civilian reports and are improved from the Vietnam era. Rapid evacuation and damage control maneuvers such as temporary shunting and early fasciotomy assist timely definitive repair and appear effective.

Enlargement of excluded PAA after surgical treatment can cause compressive symptoms. Exclusion requires adequate vascular isolation to prevent late PAA enlargement, with proximal and distal arterial ligation best performed adjacent to the aneurysm. Vein graft enlargement occurs, but this enlargement does not adversely influence patency.

This report is the first to demonstrate the effectiveness of diagnostic and therapeutic endovascular capability in the management of acute wartime injury. Implementation of this capability has unique requirements related to imaging and a trauma-specific endovascular inventory. Once established, however, endovascular capability markedly expands the injury management armamentarium and, in certain cases, provides the preferred treatment.
