Impact of COVID-19 on the surgical profile of vascular surgery patients at a tertiary hospital in Curitiba, Brazil.

Background: During the COVID-19 pandemic, healthcare services reduced the number of elective procedures performed. Vascular surgery patients are a group at risk of contracting severe forms of the infection, but are also susceptible to complications of their underlying diseases if they do not receive routine care. It is therefore necessary to understand the direct and indirect impacts and consequences of the pandemic on vascular patients.

Assessment of residual stumps 12 months after saphenectomy without high ligation of the saphenofemoral junction.

Background: Currently, the first-choice option recommended for varicose vein surgery is thermal ablation of the saphenous vein, but this procedure is not available on the Brazilian National Health Service (SUS - Sistema Único de Saúde). In an effort to improve results, surgical techniques have been developed to mimic the new technologies, without their high costs. The most prominent such method involves conventional saphenectomy, without ligation of tributaries.

Chronic venous insufficiency and graduated compression stockings: analysis of public health system patients' adherence to treatment.

Background: Chronic venous insufficiency (CVI) is a pathology of great importance due to its high worldwide prevalence, affecting up to 80% of the population. Its incidence increases with age and is more frequent in females. One of the most important treatment options is compression therapy and the main method employed is wearing graduated compression stockings, which is considered the basic treatment for CVI regardless of the patient's clinical classification.

Absence of right common carotid artery in a patient with common origin of the innominate artery and left common carotid artery.

A 50-year-old woman was referred to the noninvasive vascular laboratory for carotid artery evaluation because of a bruit in the neck. Color Doppler ultrasound examination demonstrated absence of the right common carotid artery and parallel internal and external carotid arteries originating at the brachiocephalic trunk. Computed tomography angiography further described anomalous anatomy, demonstrating a common origin of the innominate artery and left common carotid artery.

Background: Chronic venous insufficiency (CVI) is frequent and predominantly affects women, but there is a lack of information about saphenous vein reflux in the male population.

Objective: To identify different patterns of reflux in the great and small saphenous veins of men and correlate them with clinical presentation graded according to the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification.

Methods: A total of 369 lower limbs in 207 men with a clinical diagnosis of primary CVI of the lower limbs were evaluated using vascular ultrasound (VU).
