Criteria for Carotid Atherosclerotic Plaque Instability.

Background: The study aim is to determine the criteria for carotid atherosclerotic plaque instability with the use of an advanced ultrasound technology, immunohistochemical analysis, and electron paramagnetic resonance (EPR) and assess their correlations with histologic results.

Methods: A total of 92 patients were included in the study and were examined by ultrasound duplex scanning and ultrasound elastography. Plaques harvested during carotid endarterectomy were obtained for histologic analysis, immunofluorescent assay, and EPR spectroscopic measurements.

Long-Term Results of Endovascular Treatment of Chronic Iliofemoral Venous Obstructive Lesions.

Objective: To evaluate the long-term results in endovascular treatment of iliofemoral venous obstructive lesions.

Methods: From January 2009 to March 2017, 75 patients were admitted for endovascular treatment of chronic obstructive lesions of the iliofemoral veins. Of these, 60 patients underwent stenting of postthrombotic obstructions and 15 patients stenting of nonthrombotic obstructive lesions of the iliac veins (May-Thurner syndrome in 11, for tumor-induced compression and cicatricial stenosis in 4).

Bacterial Communities Associated with Atherosclerotic Plaques from Russian Individuals with Atherosclerosis.

Atherosclerosis is considered a chronic disease of the arterial wall and is the major cause of severe disease and death among individuals all over the world. Some recent studies have established the presence of bacteria in atherosclerotic plaque samples and suggested their possible contribution to the development of cardiovascular disease. The main objective of this preliminary pilot study was to better understand the bacterial diversity and abundance in human atherosclerotic plaques derived from common carotid arteries of individuals with atherosclerosis (Russian nationwide group) and contribute towards the further identification of a main group of atherosclerotic plaque bacteria by 454 pyrosequencing their 16S ribosomal RNA (16S rRNA) genes.

Long-term results of the monocusp valve formation in the common femoral vein in patients with avalvular deep veins of the lower extremities.

Background: Aim of the study was to evaluate the long-term results of the monocusp valve formation in the common femoral vein (CFV) in patients with avalvular deep veins (ADV) of the lower extremities.

Methods: A total of 36 patients (24 women and 12 men) at the age varying from 37 to 58 years old were given surgical treatment during the period from 2008 to 2014. Six patients presented with congenital ADV, while the remaining 30 ADV had a consequence of the post-thrombotic lesion in the valves with the complete recanalization and manifested deep venous axial reflux.
