title: Temporary vascular shunt for damage control of extremity vascular injury: A toolbox for trauma surgeons.
abstract: In an emergency, a general surgeon may be faced with the need to treat arterial trauma of the extremities when specialized vascular surgery is not available in their hospital setting, either because an arterial lesion was not diagnosed during pre-admission triage, or because of iatrogenic arterial injury. The need for urgent control of hemorrhage and limb ischemia may contra-indicate immediate transfer to a hospital with a specialized vascular surgery service. For a non-specialized surgeon, hemostasis and revascularization rely largely on damage control techniques and the use of temporary vascular shunts (TVS). Insertion of a TVS is indicated for vascular injuries involving the proximal portion of extremity vessels, while hemorrhage from distal arterial injuries can be treated with simple arterial ligature. Proximal and distal control of the injured vessel must be obtained, followed by proximal and distal Fogarty catheter thrombectomy and lavage with heparinized saline. The diameter of the TVS should be closely approximated to that of the artery; use of an oversized TVS may result in intimal tears. Systematic performance of decompressive fasciotomy is recommended in order to prevent compartment syndrome. In the immediate postoperative period, the need for systematic use of anticoagulant or anti-aggregant medications has not been demonstrated. The patient should be transferred to a specialized center for vascular surgery as soon as possible. The interval before definitive revascularization depends on the overall condition of the patient. The long-term limb conservation results after placement of a TVS are identical to those obtained when initial revascularization is performed.
