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.

Review Case Reports
Hybrid repair of symptomatic aberrant right subclavian artery and Kommerell's diverticulum.
An aberrant right subclavian artery (ARSA) with or without an associated Kommerell's diverticulum (KOD) is a rare vascular anomaly. Patients with an ARSA may present with a variety of symptoms, including rupture. Options for repair include open, endovascular, and a hybrid approach, with no clear consensus on which is best because of the rarity of the anomaly. We present 2 cases that underwent hybrid repair and a systematic review of the literature. ⋯ Hybrid approach to repair of an ARSA with associated KOD appears to be feasible, safe, and effective. Despite the poor quality and heterogeneity of the evidence available in the literature for this rare condition, we believe that this could be the preferred treatment option for an ARSA either with or without KOD.

Thoracic outlet syndrome (TOS) is a constellation of signs and symptoms caused by compression of the neurovascular structures in the thoracic outlet. These structures include the brachial plexus, the subclavian vein, and the subclavian artery, resulting in neurogenic (NTOS), venous (VTOS), and arterial (ATOS) types of TOS, respectively. The purpose of this study was to evaluate the outcomes of paraclavicular surgical decompression for TOS. ⋯ In our experience, surgical paraclavicular decompression can provide safe and effective relief of NTOS, VTOS, and ATOS symptoms. Functional outcomes were excellent or good in the majority of patients, with minimal complications.

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.

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.
