Long-term results of carotid body tumours surgery and predictive analytics on metastatic disease and recurrence.

Objective: The determination of clinico-surgical predictors of carotid body tumour (CBT) metastasizing and/or recurrence.

Methods: Patients with CBT but without a history of its previous treatment who had received inpatient medical aid at a tertiary surgical centre during the period 2011-2021 were retrospectively reviewed to obtain baseline data. Primary endpoints of the study were CBT metastasizing and/or local recurrence after radical surgery (composite endpoint) and overall survival.

[Contrast-enhanced ultrasonographic study in patients with lower limb arterial lesions].

Background: The introduction into clinical practice of contrast-enhanced ultrasonographic examination made it possible to assess patency of tibial arteries and perfusion of crural muscles in patients with occlusive lesions of lower-limb arteries. These findings are important for planning optimal treatment policy and assessing efficacy of operative or medicamentous treatment.

Objective: The study was aimed at investigating a possibility of contrast-enhanced ultrasound examination for assessment of patency of tibial arteries and quantitative assessment of perfusion of crural muscles in patient with occlusive lesions of lower-limb arteries.

[Staged surgical treatment of a woman with nonspecific aortoarteritis and bilateral occlusion of carotid arteries].

Nonspecific aortoarteritis (NAA) is an autoimmune disease characterized by the development of an inflammatory process in large arteries such as the aorta and its branches and pulmonary arteries. Operative interventions for lesions of the aortic arch branches may be divided into extra- and transthoracic. Involvement of all branches of the aortic arch requires transthoracic interventions to be performed.

[Hybrid approach to treatment of a patient with a thoracoabdominal aortic aneurysm].

Described in the article is a clinical case report concerning staged management of a patient presenting with a thoracoabdominal aortic aneurysm. The first stage consisted in complete lower debranching with prosthetic repair of all visceral arteries and the right renal artery. The second stage was endovascular repair of the aortic aneurysm.

[Chronic venous diseases: valvular function and leukocyte-endothelial interaction, possibilities of pharmacotherapy].

This article provides a review of the literature focusing on the data elucidating the pathogenesis of chronic venous diseases from the positions of macrohaemodynamic (venous valvular function) and microcirculatory impairments. Presented herein are confirmations of the interaction between two important mechanisms, as well as the literature data concerning the role of the venous microvalvular structures and possible haemodynamic impairments in functional venous insufficiency. Also presented are substantiations in confirmation of the theory of leukocyte-endothelial interaction, forming the basis for contemporary understanding of the pathogenesis of chronic venous diseases.
