ABSTRACT
This article describes our approach and evidence-based evaluation of popliteal entrapment syndrome. Included is a technical description of our use of preoperative intravascular ultrasound for diagnosis and operative planning in combination with our utilization of intraoperative duplex ultrasound. This evidence-based, methodical approach enables not only the correct diagnosis of the type of popliteal entrapment, but more importantly, identifies irreparable injury to the popliteal artery that would necessitate operative arterial reconstruction prior to surgery.

Despite advances in resuscitation and surgical management of combat wounds, infection remains a concerning and potentially preventable complication of combat-related injuries. Interventions currently used to prevent these infections have not been either clearly defined or subjected to rigorous clinical trials. Current infection prevention measures and wound management practices are derived from retrospective review of wartime experiences, from civilian trauma data, and from in vitro and animal data. This update to the guidelines published in 2008 incorporates evidence that has become available since 2007. These guidelines focus on care provided within hours to days of injury, chiefly within the combat zone, to those combat-injured patients with open wounds or burns. New in this update are a consolidation of antimicrobial agent recommendations to a backbone of high-dose cefazolin with or without metronidazole for most postinjury indications and recommendations for redosing of antimicrobial agents, for use of negative pressure wound therapy, and for oxygen supplementation in flight.

During combat operations, extremities continue to be the most common sites of injury with associated high rates of infectious complications. Overall, â¼ 15% of patients with extremity injuries develop osteomyelitis, and â¼ 17% of those infections relapse or recur. The bacteria infecting these wounds have included multidrug-resistant bacteria such as Acinetobacter baumannii, Pseudomonas aeruginosa, extended-spectrum ß-lactamase-producing Klebsiella species and Escherichia coli, and methicillin-resistant Staphylococcus aureus. The goals of extremity injury care are to prevent infection, promote fracture healing, and restore function. In this review, we use a systematic assessment of military and civilian extremity trauma data to provide evidence-based recommendations for the varying management strategies to care for combat-related extremity injuries to decrease infection rates. We emphasize postinjury antimicrobial therapy, debridement and irrigation, and surgical wound management including addressing ongoing areas of controversy and needed research. In addition, we address adjuvants that are increasingly being examined, including local antimicrobial therapy, flap closure, oxygen therapy, negative pressure wound therapy, and wound effluent characterization. This evidence-based medicine review was produced to support the Guidelines for the Prevention of Infections Associated With Combat-Related Injuries: 2011 Update contained in this supplement of Journal of Trauma.

Endovascular therapy has become an accepted mode of therapy for lifestyle-limiting claudication, especially if the disease is confined to the superficial femoral artery (SFA). The standard approach to these lesions is from the contralateral femoral artery and crossing over the aortic bifurcation. In patients who have an aortobifemoral bypass (AFB), this technique is usually not feasible secondary to the angles of the graft. The authors report on their approach to a 60-year-old man with lifestyle-limiting claudication and SFA disease, and an AFB in place. They performed a retrograde approach to the SFA via a small above-knee popliteal artery exposure. They used the recently approved (in the United States) heparin-bonded VIABAHN for the revascularization via this approach, which would have allowed them to proceed to an open bypass procedure if they were unsuccessful in the same setting.

Fibromuscular dysplasia is a multifactorial arteriopathy that primarily affects small and medium-sized arteries. It is most common in the renal and internal carotid arteries. Pathological classification is based on the arterial wall layer most significantly involved. The natural history and incidence of asymptomatic disease is unknown. The most common lesions become symptomatic as a high-grade stenosis producing renovascular hypertension or as an embolic source for the cerebral circulation. Treatment is reserved for symptomatic lesions. Most simple lesions are effectively treated by catheter-based intervention. Surgical therapy is warranted for more complex lesions. Both produce durable, long-term results.

PURPOSE: To describe the successful use of percutaneous mechanical thrombectomy as an adjunct to thrombolysis for acute subclavian vein thrombosis due to venous thoracic outlet syndrome. CASE REPORT: A 40-year-old man presented with arm swelling due to acute subclavian vein thrombosis and venous thoracic outlet syndrome. Percutaneous mechanical thrombectomy with the AngioJet device and thrombolysis were used to restore venous patency. Immediately following operative thoracic outlet decompression, the patient experienced rethrombosis, which was successfully treated using percutaneous mechanical thrombectomy. After 6 months, the patient remains symptom-free, with a patent subclavian vein by duplex ultrasonography. CONCLUSIONS: Thrombus debulking or removal with percutaneous mechanical thrombectomy devices may reduce the amount or duration of thrombolytic therapy required, making treatment of venous thoracic outlet syndrome safer. Moreover, patients with recurrent thrombosis after thoracic outlet decompression may be safely treated with percutaneous mechanical thrombectomy, even when thrombolytic therapy is contraindicated.
