Vascular Access Challenges in Thoracic Endovascular Aortic Repair: A Literature Review.

Background: This review aims to comprehensively summarize access challenges in thoracic endovascular aortic repair (TEVAR) by describing vascular access routes, associated risks, outcomes, and complications.

Methods: A literature search was conducted utilizing the PubMed (Medline), Scopus, and Web of Science databases. Qualitative and quantitative data from selected studies are extracted and discussed according to available standards for narrative reviews.

Prevalence and Complications of Aberrant Subclavian Artery in Patients With Heritable and Nonheritable Arteriopathies.

Background: An aberrant subclavian artery (ASA) (or lusoria) is the most common congenital anomaly of the aortic arch (0.5%-2.2%; female-to-male ratio 2:1 to 3:1).

1-Year Results From a Prospective Experience on CAS Using the CGuard Stent System: The IRONGUARD 2 Study.

Objectives: The aim of this study was to evaluate the 1-year safety and efficacy of a dual-layered stent (DLS) for carotid artery stenting (CAS) in a multicenter registry.

Background: DLS have been proved to be safe and efficient during short-term follow-up. Recent data have raised the concern that the benefit of CAS performed with using a DLS may be hampered by a higher restenosis rate at 1 year.

Regional Survey in Lombardy, Northern Italy, on Vascular Surgery Intervention Outcomes During The COVID-19 Pandemic.

Objective: The characteristics and outcomes of patients undergoing vascular surgery hospitalised and managed in Lombardy are described with a comparison of patients tested positive for COVID-19 (CV19-pos) vs. those tested negative (CV19-neg).

Methods: This was a multicentre, retrospective, observational cohort study which involved all vascular surgery services in Lombardy, Northern Italy.

Differences in hub and spoke vascular units practice during the novel Coronavirus-19 (COVID-19) outbreak in Lombardy, Italy.

Background: To highlight differences in clinical practice among referral (hub, HH) or satellite (spoke, SH) hospital vascular surgery units (VSUs) in Lombardy, during the COVID-19 pandemic "phase 1" period (March 8 - May 3, 2020).

Methods: The Vascular Surgery Group of Regione Lombardia Register, a real-word, multicenter, retrospective register was interrogated. All patients admitted with vascular disease were included.

1-Month Results From a Prospective Experience on CAS Using CGuard Stent System: The IRONGUARD 2 Study.

Objectives: This study sought to evaluate 30-day safety and efficacy of dual-layer mesh-covered carotid stent systems for carotid artery stenting (CAS) in the clinical practice.

Background: When compared with carotid endarterectomy, CAS has been associated with a higher rate of post procedural neurologic events; these could be related to plaque's debris prolapsing through stent's mesh. Consequently, the need for increased plaque coverage has resulted in the development of dual-layer mesh-covered carotid stent systems.

Combined Transcatheter Treatment of Severe Aortic Valve Stenosis and Infrarenal Abdominal Aortic Aneurysm in Increased Surgical Risk Patients.

The prevalence of combined severe aortic stenosis and abdominal aortic aneurysm is increasing with the aging of the population. Both conditions are associated with adverse outcome if not adequately managed. The choice of the optimal treatment of these patients is challenging and no clear recommendations are available.

Impact of carotid stent cell design on vessel scaffolding: a case study comparing experimental investigation and numerical simulations.

Purpose: To quantitatively evaluate the impact of carotid stent cell design on vessel scaffolding by using patient-specific finite element analysis of carotid artery stenting (CAS).

Methods: The study was organized in 2 parts: (1) validation of a patient-specific finite element analysis of CAS and (2) evaluation of vessel scaffolding. Micro-computed tomography (CT) images of an open-cell stent deployed in a patient-specific silicone mock artery were compared with the corresponding finite element analysis results.

Endovascular treatment of acute type B dissection and Kommerell's diverticulum.

A 59-year-old man presented with severe hypertension and resistant interscapular pain. Transesophageal echocardiography and computed tomographic angiogram demonstrated acute type B dissection associated with aberrant right subclavian artery with 3.5 cm Kommerell's diverticulum.

Deferment of objective assessment of deep vein thrombosis and pulmonary embolism without increased risk of thrombosis: a practical approach based on the pretest clinical model, D-dimer testing, and the use of low-molecular-weight heparins.

Background: Treatment of patients with suspected deep vein thrombosis (DVT) or pulmonary embolism (PE) is problematic if diagnostic imaging is not immediately available. Pretest clinical probability (PCP) and D-dimer assessment can be used to identify patients for whom empirical protective anticoagulation is indicated. To evaluate whether PCP and D-dimer assessment, together with the use of low-molecular-weight heparins (LMWHs), allow objective appraisal of DVT and PE to be deferred for up to 72 hours, patients with suspected DVT and PE were prospectively examined.
