Closed dislocation of the knee with complete popliteal rupture is an uncommon injury. It requires prompt recognition and treatment to prevent limb loss. We describe a case of acute ischemia caused by complete knee dislocation with rupture of the popliteal artery that was successfully repaired with superficial femoral artery transposition. To the best of our knowledge, this is the first reported clinical experience of the use of an arterial autograft for revascularization of traumatic popliteal artery rupture.

Case Reports
Endovascular stent-graft treatment for a traumatic vertebrovertebral arteriovenous fistula with pseudoaneurysm.
The rarely occurring vertebrovertebral arteriovenous fistula (VVAVF) is characterized by abnormal direct communications between the vertebral artery or its branches and the neighboring venous system. We present our experience using a stent graft to occlude a chronic, traumatic VVAVF. ⋯ The fistula and pseudoaneurysm disappeared immediately. After 9 months, the patient remained asymptomatic with a patent stent.

Indications for anterior thoracolumbar spine interbody fusion have expanded because of safe and expeditious surgical exposure that can be provided by the approach surgeon. In our practice, previous anterior interbody instrumentation, multiple disc level exposure, patient age, and body habitus are not surgical deterrents despite the potential for increased complications. The arterial and venous complications of anterior spine exposure have been well documented; however, the purpose of this study is to document the incidence of other complications, such as deep vein thrombosis (DVT), lymphedema, seroma/hematoma, wound infection, and hospital readmission and to determine whether outcome is influenced by the factors mentioned above. ⋯ The overall incidence of nonvessel injury complications after anterior thoracolumbar spine exposure is low. Redo anterior spine exposure and redo disc exposure cases, including those that require hardware or artificial disc removal, can be performed safely. Multidisc level exposure is, however, associated with an increased incidence of lymphedema, wound infection, and hospital readmission. Patients with BMI >30 kg/m(2) should be approached with caution because there is a significantly increased rate of DVT, wound infection, and hospital readmission.

We report 2 patients with symptomatic aortic aneurysm and serologic evidence of acute Q fever with positive Coxiella burnetii PCR in blood/tissue. This suggests a role for acute Q fever in aneurysm progression. Diagnostic testing for Q fever infection in patients with symptomatic aneurysms in Q fever areas is recommended.

Traumatic transection of the thoracic aorta is a life-threatening complication that most commonly occurs after high-speed motor vehicle collisions. Although such injuries were previously treated with open surgical reconstruction, they are now more commonly being treated with endovascularly placed stent grafts. Unfortunately, most stent grafts are designed for treating aortic aneurysmal disease instead of traumatic injury. Further refinements in stent graft technology depend on a thorough anatomic understanding of the transection injury process. ⋯ In this contemporary series from a large trauma center, 91% of patients are anatomically able to be treated with a stent graft that does not require coverage of the left common carotid artery. Most patients have an aortic diameter that falls between 21 and 26 mm in diameter, as well as a short segment of injured artery. Centers interested in emergently treating aortic transections are able to do so while maintaining a limited stock of stent grafts that can be used to treat the majority of the population.
