How to recognize stent graft infection after endovascular aortic repair: the utility of 18F-FDG PET/CT in an infrequent but serious clinical setting.

Objective: To evaluate the diagnostic performance of F-FDG PET/CT in the detection of stent graft infection (SGI).

Methods: In a retrospective study, two nuclear medicine physicians have independently analyzed 17 F-FDG PET/CT examinations performed for clinical suspicion of SGI. The images were evaluated for the uptake pattern and intensity, and by the maximum standard uptake value (SUV), the target-to-background ratio with blood pool (TBR) and liver uptake (TBR) as a reference.

Percutaneous Mechanical Thrombectomy Using Rotarex® S Device in Acute Limb Ischemia in Infrainguinal Occlusions.

Purpose: To evaluate the effectiveness of percutaneous mechanical thrombectomy using Rotarex S in the treatment of acute limb ischemia (ALI) in infrainguinal occlusions in a retrospective study of patients treated in our institution.

Methods: In this study, we identified a total of 147 ALI patients that underwent mechanical thrombectomy using Rotarex S at our institution. In 82% of the cases, percutaneous thrombectomy was used as first-line treatment, and for the remainder of the cases, it was used as bailout after ineffective aspiration or thrombolysis.

[A rare case of mobile atherosclerotic plaque with a high embolic potential in the femoral artery].

Atherosclerosis is a diffuse disease which may lead to the development of unstable atherosclerotic plaque. Its rupture can result in acute ischemic event. The atherosclerotic plaques with a mobile component are typical presentations of such instability and patients with these plaques are at high risk of acute ischemic events.

Acute Digital Ischemia Associated with Closed Injury.

Injury of an artery has a significantly worse prognosis for the patient than a venous injury. Blunt injuries of lower limb digital arteries with the development of acute ischemia present a very rare phenomenon. A crush mechanism with a defect of the non-wetted surface of vessel's inner part and the development of subsequent thromboischemic lesion is essential for the development of ischemia.

[Deep calf vein thrombosis].

Isolated calf vein thrombosis in the population of patients with deep vein thrombosis is found approximately in 10 to 25 % of cases. We present 3 cases of calf vein thrombosis which occurred due to unusual causes. Specific characteristics of this form of thromboembolic disease are discussed and compared to proximal deep vein thrombosis with emphasis to symptoms, risk of complications, prognosis and therapeutic approach.

Magnetic resonance angiography, digital subtraction angiography and Doppler ultrasonography in detection of carotid artery stenosis: a comparison with findings from histological specimens.

Background: Patients' life expectancy, clinical symptomatology and the extent of carotid stenosis are the most important factors when deciding whether to perform carotid endarterectomy (CEA) in patients with carotid stenosis. Therefore, the accuracy of measuring carotid stenosis is of utmost importance.

Methods: Patients with internal carotid artery (ICA) stenosis were investigated by digital subtraction angiography (DSA), Doppler ultrasonography (DUS) and magnetic resonance angiography (MRA).
