    Abstract Introduction: Chronic kidney disease prevalence has been increasing worldwide, with an increasing need to deliver an effective treatment. During the first months of the coronavirus disease 2019 (COVID-19) pandemic healthcare systems around the world were under stress. Therefore, the aim of this study is to report a single center experience with arteriovenous fistula (AVF) creation while also evaluating the impact of COVID-19.
    Methods: Procedures for AVF creation in a tertiary hospital between March 2017 and December 2020 were included in this study and their case records were retrospectively analyzed and data retrieved.
    Results: A total of 582 procedures were performed and a total of 568 accesses were created (506 being made pre-COVID onset and 62 post-COVID onset). The period between the referral to the vascular surgery consultation was significantly longer for the COVID group [18 (23) days vs 28 (44) days; p<0,001] while the period between the consultation to the surgery was significantly shorter [76 (77) days vs 40 (57) days; p<0,001]. This resulted in significantly less time between referral to surgery in the COVID group [103 (77) days vs 88 (55) days; p=0,008].
    Conclusion: The ability of hospitals to adapt their resources was paramount to mitigate COVID impact. In the institution where the study took place, the time from referral to consultation was increased significantly during the first months of COVID but the time from consultation to surgery was significantly reduced. Overall, these results show that there was a successful effort to expedite the creation of a vascular access.

    Abstract 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) (
    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.

    Abstract Chronic venous disease is a potentially prevalent and debilitating condition affecting millions of individuals, mostly in Western world. Predisposing genetic and environmental factors contribute to its development. However, the main etiology remains to be elucidated. An extensive literature search was conducted in Medline using the following key words algorithm: ("Chronic venous disease" OR "Chronic venous insufficiency" OR "varicose veins") AND ("endothelial dysfunction" OR "inflammation"). Besides being a multifactorial disease, it is now recognized that the hallmark of chronic venous disease pathophysiology likely remains in inflammation, possibly triggered by sustained venous hypertension and valvular incompetence. Shear stress changes are directly sensed by endothelial cells, leading to its activation and subsequent recruitment of leukocytes and release of proinflammatory agents. Dysfunctional endothelium has a pivotal role perpetuating the inflammatory cascade, with consequent pathological venous changes and chronic venous disease worsening. Endothelial dysfunction may be the central player in the link between varicose veins and deep vein thrombosis. In this article, we aim to analyze the crucial role of endothelial activation in the persistent inflammatory cycle that characterizes chronic venous disease.

    Abstract Background: In countries without organized population screening, incidental detection remains the major form of abdominal aortic aneurysm (AAA) diagnosis. Despite the presumed homogeneity in AAA prevalence, its rate of repair is highly variable, with Portugal treating 2 to 6 times fewer AAA per habitant than other western countries.
    Objectives: To evaluate the detection rate and monitoring of incidental AAA in a multicentre cohort from Portuguese hospitals.
    Methods: All abdominal CT scans performed in men ≥ 65 years old in three major Portuguese hospitals between January and June 2018 were selected for review. CT scans prescribed by the Vascular Surgery or Emergency Departments were excluded. Patients with previously known AAA were also excluded. Subjects with newly detected aneurysms were assessed for the two primary outcomes: the description of the finding by the radiologist in the written report; the effective follow-up recommendations by the prescriber of the CT or by the general practitioner (GP). Patients with newly found AAA that met criteria for monitoring or treatment and failed to be given guidance were contacted and included in surveillance programs.
    Results: Overall, 3292 abdominal CT scans were selected for review. A total of 133 newly found aneurysms were detected (4.2% prevalence in the cohort). Of those, 48 cases (36%) were not described by the radiologist in the written report. Further 42 patients (32%) were not successfully oriented by the ordering physician or GP, despite having had their AAA mentioned. Overall, only 32% (n = 42) of the newly diagnosed AAA were correctly identified and referred to monitoring.
    Conclusions: Incidental AAA is a common occurrence in in-hospital abdominal CTs. A significant number is not documented by the radiologist and the vast majority is not referred to monitoring. This could be a major reason for the low elective treatment rate of AAA in Portugal.

    Abstract Introduction: The parallel grafting technique (PGT) is a valuable alternative to prefabricated branched or fenestrated endovascular aortic repair. An often overlooked advantage of PGT is its unique adaptability to different anatomical challenges that might appear intra-operatively.
    Report: A 72 year old male patient presented with a 60 mm thoracic aneurysm, 59 mm juxtarenal abdominal aortic aneurysm, and 32 mm common iliac aneurysm (CIAA). Thoracic endovascular aortic repair plus endovascular aortic repair with bilateral renal artery chimneys and CIAA exclusion applying the sandwich technique was proposed. Because of unfavourable angulation it was not possible to achieve selective left renal catheterisation via axillary access. Changing to a femoral approach allowed successful retrograde catheterisation. The procedure ended with a chimney for the right renal artery and a periscope for the left renal artery. The final angiogram showed no endoleaks and renal and hypogastric patency. The patient was discharged three days after the procedure and remains under ultrasound surveillance after 40 months because of a small type two endoleak.
    Conclusion: When using a prefabricated branched device, the possibility of selectively catheterising a visceral branch often has no straightforward solution. However, parallel grafting is an extremely flexible technique, which was of paramount importance for the surgical outcome of the present case.

    Abstract Endothelial dysfunction is one of the earliest indicators of cardiovascular (CV) dysfunction, and its evaluation would be of considerable importance to stratify CV risk of many diseases and to assess the efficacy of atheroprotective treatments. Flow-mediated dilation is the most widely used method to study endothelial function. However, it is operator-dependent and can be influenced by physiological variations. Circulating biomarkers are a promising alternative. Due to the complexity of endothelial function, many of the biomarkers studied do not provide consistent information about the endothelium when measured alone. New circulating markers are being explored and some of them are thought to be suitable for the clinical setting. In this review, we focus on novel biomarkers of endothelial dysfunction, particularly endothelial microparticles, endocan, and endoglin, and discuss whether they fulfill the criteria to be applied in clinical practice.

    Abstract Objective: Ruptured abdominal aortic aneurysm (rAAA) is a lethal condition that requires acute repair to prevent death. This analysis aims to assess the nationwide trends in rAAA admission, repair and mortality in a country, Portugal, without national screening for AAA.
    Methods: rAAA registered in the hospital administrative database of the National Health Service and all nationally registered deaths due to rAAA based on death certificate data were analysed. Three time periods (2000-2004, 2005-2009, and 2010-2015) were compared in patients ≥ 50 years old to assess the variations over time.
    Results: A total of 2 275 patients ≥50 years old with rAAA were identified in the two databases from 2000 to 2015. The age standardised incidence of rAAA was 2.78 ± 0.24/100 000/year in 2000-2004, 3.17 ± 0.39/100 000/year in 2005-2009 and 3.21 ± 0.28/100 000/year in 2010-2015 (p < .001). When comparing the time periods 2000-2004 to 2005-2009, the age standardised rate of admission (n = 1460) increased from 1.57 ± 0.25/100 000/year to 2.24 ± 0.32/100 000/year (p < .001). The operative mortality rates decreased during this time period (from 55.3 ± 4.7% to 48.8 ± 4.7%, p < .001). In 2010-2015, the age standardised rate of admissions due to rAAA decreased (1.98 ± 0.22/100 000/year). Operative mortality remained stable (48.9 ± 6.2%). The rate of patient deaths outside the hospital decreased from the first to the second period (1.21 ± 0.10/100 000/year and 0.93 ± 0.29/100 000/year, respectively) but later increased (1.14 ± 0.22/100 000/year). This resulted in a higher overall rAAA related mortality in Portugal in the third period (2.20 ± 0.18/100 000/year, 2.21 ± 0.27/100 000/year and 2.26 ± 0.26/100 000/year in 2000-2004, 2005-2009, and 2010-2015, respectively, p < .001).
    Conclusion: Overall, the incidence of rAAA in Portugal has been stable over the past 10 years. The rates of admission, repair, and death due to rAAA repair seem to have reached an inflection point and are now decreasing. Mortality outside the hospital remains a matter of concern, warranting further planning of streamlined transfer networks and vascular surgical departments.

    Abstract A 59-year-old man was referred with complicated chronic type B aortic dissection. Despite the false lumen's being dominant in terms of caliber and limb perfusion, visceral arteries originated in a 9-mm true lumen. A staged approach was performed: open aortobi-iliac bypass with preservation of both lumens to the infrarenal aorta, with reinforcement of the aorta and anastomosis with Dacron (wrap technique); exclusion of the dissection by endografting all of the false lumen with three successive thoracic endoprostheses; and maintenance of true lumen perfusion using two periscopes with self-expanding nitinol stents. The patient remains asymptomatic after 1 year of follow-up.
