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.

[Antithrombotic therapy after venous stenting].

Presented herein is a literature review considering the problems of using antithrombotic therapy after venous stenting. Described herein are the literature data according to which the authors give preference to anticoagulant therapy (low-molecular-weight heparins, vitamin K antagonists, direct oral anticoagulants). This is followed by considering the problems of duration of treatment depending on various clinical situations.

Diagnosis and surgical treatment of a persistent sciatic artery aneurysm.

The persistent sciatic artery is situated superficially in the gluteal region wherein it can be traumatized in normal daily activities: during a prolonged sitting position or while attempting to sit down. This leads to an early atherosclerotic lesion of the sciatic artery, to the development of aneurysmatic dilatation, and damage to the arterial wall. The present article describes a 72-year-old female patient presenting with a persistent sciatic artery of the left leg and a PSA aneurysm which consequently resulted in critical ischaemia of her left lower limb.

[Method of determining disease severity in women with pelvic varicose veins].

Background: Using assessment scales in clinical and research practice is one of fundamental reference methods of evaluation in human pathological states. Pelvic vein varicosity is an independent nosological entity within the framework of chronic vein diseases. Currently, the clinical methods of assessment in the aspect of a patient-oriented approach in this type of disease are largely understudied and still not duly defined.

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).
