Endovascular repair of blunt extremity arterial injury: case report

Surgical revascularization is the standard treatment of complex blunt traumatic extremity vascular injuries. Limb salvage may be improved with minimally invasive endovascular therapies because of the ability to perform diagnostic and therapeutic intervention simultaneously. Two cases of acute limb-threatening arterial injuries successfully treated with percutaneous endovascular therapy are reported.

A skier suffered hemodynamic instability after shoulder reduction. An axillary arterial injury was suspected and confirmed with angiography. A covered stent successfully controlled the hemorrhage. A morbidly obese female sustained anterior dislocation of her left knee 7 years previously requiring repair. She developed recurrent knee dislocation with acute leg ischemia. Emergent fixation was performed followed by percutaneous angiography. Short segment thrombosis of the popliteal was noted. Wire recanalization of the thrombosed artery and stent placement restored 3-vessel runoff.

Endovascular therapy can offer faster, easier access to the extremity vascular injury facilitating revascularization and avoiding long incisions and dissections.
