Objectives: Chronic venous disease (CVD) is a prevalent pathology, and endothelial dysfunction is recognized as a core of its physiopathology. Flow-mediated dilation (FMD) is one of the most widely used tests for evaluating endothelial function. The aim of this study is to evaluate the influence of varicose vein (VV) surgery on FMD. Methods: A prospective study with patients with superficial CVD and saphenous incompetence on Doppler ultrasonography that were proposed for VV surgery. The FMD test was performed before and 6 months after the procedure. The operator performing the post-operative evaluation was blinded to the pre-operative result. Results: A total of 42 patients were included in the analysis. The median pre-operative percent change of FMD was 4.20% (±1.30) and the post-operative was 4.56% (±1.25) ( p = 0.819). Conclusions: Our findings do not corroborate the presence of an overall endothelial dysfunction prone to modulation by surgery. Nevertheless, further studies are needed to confirm our findings.

Tuberculosis is a prevalent infection worldwide, especially in low-income countries. Its manifestations are diverse, and although pulmonary affection is the most common presentation, aortic involvement has been described. When present, such involvement can ultimately result in aortic aneurysm. Tuberculous aortic aneurysm (TAA) is a rare clinical entity with few cases described to date. We present a case of tuberculous lymphadenitis with pseudoaneurysm of the abdominal aorta in an otherwise healthy patient.

Vascular access (VA) maintenance is challenging in complex dialysis patients, where patient-centered approaches are decisive. Arteriovenous grafts (AVGs) provide an alternative for those unsuitable for autogenous arteriovenous fistula (AVF). However, AVFs and AVGs are prone to complications such as stenosis, aneurysm, and thrombosis, leading to dysfunction and morbidity in these patients. This report focuses on the journey of an extraordinary longevity of a 15-year-old AVG in a 54-year-old female patient, detailing multiple interventions required to maintain its patency. The case also underscores the role of a multidisciplinary team in achieving long-term success.
