Purpose: The purpose of the paper is to report the clinical outcomes of 4 patients with ruptured abdominal aortic aneurysm (AAA) during (3 patients) or immediately after (1 patient) moderate-severe SARS-CoV-2 infection. We discuss COVID-19-related mechanisms which could impact AAA rupture., Patients and Methods: During the period of the pandemic (March 2020-May 2021), we performed surgery in 18 patients with ruptured AAA. Four patients were affected by moderate or severe SARS-CoV-2 infection (in 3 patients the rupture occurred during the infection and in 1 patient 3. months after discharge from the hospital). Two patients underwent open repair and 2 endovascular surgery., Results: No postoperative mortality and no major complication occurred. Rapid growth of the AAA in comparison with a previous Duplex scan was evident in all 4 patients., Conclusions: Family doctors and vascular surgeons should be aware about the possibility of AAA degeneration in patients with moderate-severe COVID19 infection. The risk is increased by steroid therapy which is essential in more advanced stages of the infection. In this clinical setting, endovascular repair is a valid choice.

Background: The aim of our study was to compare COVID-19- and not-COVID-19-related mortality rates in two Italian regions during the pandemic period when the same isolation rules and therapeutic approaches were introduced for all hospitals in Italy. Risk factors for not-COVID-19-related deaths during the pandemic were analyzed; we tried to assess a possible correlation between reducing hospital visits and "deferrable" vascular operations and the increased cardiovascular mortality not related to COVID-19 infection., Methods: We analyzed COVID-19- and not-COVID-19-related mortality rates in two Italian regions in the period January 2020-January 2021. We compared mortality rates during the pandemic period with those of the previous five years. We tried to determine the factors involved in increased mortality rates during the pandemic period., Results: Despite the same isolation rules for people and the same therapeutic approaches for hospitals, mortality rates did not increase in the region Lazio, where the pandemic was not severe. In the region Lombardy, the mortality rate was doubled in comparison with the previous years, and 50% of the increase was related to not-COVID-19 deaths., Conclusions: The increase in mortality rates for not-COVID-19-related deaths in the region Lombardy was connected to the generalized turmoil in the acute phase of an overwhelming pandemic, including diffuse stress, inadequate communications, reluctance to ask for medical help unless symptoms were severe, and unexpected inadequate number of health workers, hospital beds, and intensive care unit beds. Reduced hospital visits may have had a fundamental role., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Primary tumors originating within the wall of the arteries are rare and they frequently manifest late, making effective treatment a challenge. We describe here a case of Abdominal Aorta AngioSarcoma masqueraded as an infected EndoVascular Aortic Repair. The knowledge of this pathology from vascular surgeons and radiologist is crucial, because a prompt diagnosis and treatment can improve the prognosis., (Copyright © 2021. Published by Elsevier Inc.)

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection represents a serious threat to public health because it leads to a wide spectrum of clinical manifestations. The region Lombardia (Italy) has suffered from severe problems during the acute phase of the outbreak in Italy (March-April 2020). The aim of our analysis is to report the experience of the Department of Vascular Surgery of Pavia, including the learned lessons and future perspectives, considering that the COVID-19 outbreak is in its acute phase in other continents., Material and Methods: Single-center, retrospective, observational study based on extracted data from the medical records of all consecutive COVID-19 patients observed in our Vascular Department between March 1st and April 30th, 2020. We reviewed the records for demographic information, comorbidities, laboratory tests, and anticoagulation treatment at the time of hospital admission., Results: We observed an important reduction in elective and urgent interventions compared to the same period of the previous year; in parallel, we observed an increase in the diagnosis of deep vein thrombosis (DVT) in hospitalized patients, especially with severe infection. In our department, four infections were reported among health workers., Conclusions: The impact of the COVID19 pandemic on health-care delivery has been massive. A wave of vascular-related complications is expected. Regular SARS-CoV-2 screening, adequate protection, and quick reorganization of health-care resources are still needed., (Copyright © 2020 Elsevier Inc. All rights reserved.)

The 10-30% of iliac aneurysms involve the internal iliac arteries (IIAs), and their repair still remains a challenge. The endovascular techniques have become the treatment of choice in relation to the improvement of materials, techniques, and less morbidity/mortality compared with open surgery. Regardless of the use of open or endovascular surgery, the preservation of hypogastric blood flow is strongly recommended in the case of occlusion of the contralateral. We describe a case of the use over the instructions for use (IFU), of the GORE Excluder iliac extension for the total successful endovascular exclusion of a voluminous IIA aneurysm in chronic contralateral occlusion. This use over the IFU is applicable and effective in selected patients., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: The Lombardy region suffered severely during the acute phase of the coronavirus disease 2019 outbreak in Italy (Mar-Apr 2020) with 16,000 diagnosed coronavirus disease 2019-related deaths (49% of the total coronavirus disease 2019-related deaths in Italy). In the area surrounding Pavia during the critical stage of the outbreak (Mar-Apr 2020), 1,225 of the documented 4,200 deaths were related to coronavirus disease 2019 infection, with a mortality rate of 181/100,000 inhabitants and an increase in deaths of 138% compared with the same period during previous years. Our aim was to report the experience of the Department of Vascular Surgery of Pavia (Lombardy, Italy), including the lessons learned and future perspectives regarding the management of coronavirus disease 2019 patients who developed severe acute ischemia with impending lower limb loss or deep vein thrombosis., Materials and Methods: We carried out a retrospective data collection of coronavirus disease 2019 patients with severe acute ischemia of the lower limbs or deep vein thrombosis, which we observed in our department during the period March 1, 2020, to April 30, 2020. Primary outcomes of the analysis were postoperative mortality for all patients and amputation rates only in those coronavirus disease 2019 patients suffering from acute lower limb ischemia. Secondary outcomes were the prevalence of the disease among admitted coronavirus disease 2019 patients, and any possible correlation among inflammatory parameters, thrombolytic status, and the presence of acute ischemia or deep vein thrombosis., Results: We observed 38 patients (28 male) with severe coronavirus disease 2019 infection (6 with lower limb arterial thrombosis and 32 with deep vein thrombosis). The median patient age was 64 years (range 30-94 y). In the arterial group, 3 had thrombosis on plaque and 3 on healthy arteries ("simple" arterial thrombosis). All underwent operative or hybrid (open/endo) revascularization; 1 patient died from major organ failure and 1 patient underwent major amputation. In the deep vein thrombosis group, 9 (28%) patients died from major organ failure, despite aggressive medical therapy. In patients with simple arterial thrombosis and those with deep vein thrombosis, we observed a decrease in inflammatory parameters (C-reactive protein) and in D-dimer and fibrinogen after aggressive therapy (P <.001)., Conclusion: Our study confirms that critically ill, coronavirus disease 2019 patients who develop arterial and deep vein thrombosis have a high risk of mortality, but, if treated properly, there is an improvement in overall survival, especially in patients of 60 years of age or younger., (Copyright © 2020 Elsevier Inc.

Little or nothing is known about the correlation between the upper limb deep vein thrombosis (UL-DVT) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We describe the increased risk of UL-DVT in 3 patients with SARS-CoV-2 who require continuous positive airway pressure with a hood and the need for early adequate antithrombotic prophylaxis., (Copyright © 2020 Elsevier Inc.
