Dynamic computed tomography angiography for noninvasive diagnosis of bow Hunter's syndrome: a case report.

The focus of this case report is to technically describe a noninvasive diagnostic evaluation of bow Hunter's syndrome using a dynamic computed tomography angiography protocol and discuss its advantages. In addition, we aimed to exemplify the quality of the study by presenting images of a 3D-printed model generated to help plan the surgical treatment for the patient. The dynamic computed tomography angiography protocol consisted of a first image acquisition with the patient in the anatomic position of the head and neck.

Incidence, diagnosis, treatment methods, and outcomes of clinically suspected venous thromboembolic disease in patients with COVID-19 in a quaternary hospital in Brazil.

Background: Prothrombotic states have been associated with viral infections and the novel Sars-COV-2 infection has been associated with elevated D-dimer levels, although no causal relation has been clearly established.

Objectives: This study presents an epidemiological analysis of manifest VTE episodes in a group of patients hospitalized because of COVID-19.

Methods: Medical records of patients who presented symptomatic deep vein thrombosis and/or pulmonary embolism in concomitance with confirmed COVID-19 were retrospectively studied.

Analysis of risk factors and diseases associated with atherosclerosis in the progression of carotid artery stenosis.

Objective: The objective of this study was to analyze the roles of demographic, clinical, and laboratory factors on the progression of atherosclerotic stenosis in carotid bifurcation. It was based on prospective information from records entered on a specific application form for follow-up outpatients at a tertiary university service.

Methods: Consecutive symptomatic and asymptomatic patients (n = 210) who had undergone more than one carotid duplex scan but no surgical intervention were selected for the analysis.
