National Diagnostic Reference Levels for Standard Descending Thoracic Endovascular Aortic Repair and Optimisation Strategies.

Objective: The International Commission on Radiological Protection has highlighted the large number of medical specialties that use fluoroscopy outside diagnostic imaging departments without radiation protection programmes for patients and staff. Vascular surgery is one of these specialties. Thoracic endovascular aortic repair (TEVAR) is a complicated procedure requiring radiation protection guidance and optimisation.

Optimizing Venous Stenting: Consensus Recommendations for Enhanced Management of Lower Extremity Deep Vein Thrombosis.

Introduction:  Deep vein thrombosis (DVT) poses a complex challenge and often leads to postthrombotic syndrome (PTS), a debilitating complication. The emergence of venous stents offers a potential preventive avenue against this complication. This study aimed to provide consensus recommendations on the use of venous stent for DVT.

International Union of Angiology consensus document on vascular compression syndromes.

Vascular compression syndromes (VCS) are rare diseases, but they may cause significant symptoms interfering with the quality of life (QoL) of patients who are often in their younger age. Given their infrequent occurrence, multiform clinical and anatomical presentation, and absence of dedicated guidelines from scientific societies, further knowledge of these conditions is required to investigate and treat them using modern imaging and surgical (open or endovascular) techniques. This consensus document will focus on known VCS, affecting the arterial and venous system.

Endovascular Technique for Ascending Aorta Repair Based on TEVAR and TAVI Procedures.

Purpose: Ascending aorta (AAo) acute pathology still has an open-surgery indication with a high mortality rate associated to cardiopulmonary bypass and circulatory arrest. In these cases, the endovascular aortic approach could be an excellent option. The aim of the present study is to detail an optimized technique for the endovascular treatment of AAo diseases, based on thoracic endovascular aortic repair (TEVAR) and transcatheter aortic valve implantation (TAVI) procedures.

Skin and Arterial Wall Deposits of 18F-NaF and Severity of Disease in Patients with Pseudoxanthoma Elasticum.

Pseudoxanthoma elasticum (PXE) is a genetic disease characterized by the calcification of elastin fibers. Our aim was to quantify vascular calcification in the arteries and the deposition of 18F-sodium-fluoride (18F-NaF) in the skin and vessel walls with positron emission tomography/computed tomography. This was an observational study including 18 patients with PXE.

A Rare Case of Ischemia-Reperfusion Injury After Mesenteric Revascularization.

Endovascular treatment of chronic mesenteric ischemia is currently the treatment of choice, regardless of the number of involved vessels. Unlike other anatomic areas, the hyperperfusion produced by revascularization and the consecutive reperfusion syndrome is only described in cases of acute bowel ischemia, which is usually resolved with traditional surgery. We present a case of severe hyperperfusion syndrome secondary to endovascular correction with stents of a critical ischemia affecting the celiac trunk and superior mesenteric artery.

Endovascular treatment of posterior nutcracker syndrome with a new autoexpandable stent.

The endovascular treatment of nutcracker syndrome is currently considered by some to be the preferred treatment option in this pathologic process despite its risks. However, currently, there are few data about the pure endovascular approach in the posterior nutcracker syndrome related to evolution in the midterm. We present two successful cases of a complete endovascular approach in this disease, with follow-up of 9 months and 17 months without complications.

Endovascular Treatment of Complex Carotid-Jugular Fistula.

Inadvertent complications of jugular vein catheterization are not uncommon, however, a persistent symptomatic carotid-jugular fistula has been rarely reported. A 72-year-old male with infected surgical wound after coxofemoral disarticulation for sarcoma presented with symptoms of acute right heart failure. A fistula between the right common carotid artery (CCA) and the internal jugular vein was demonstrated on Doppler ultrasound and confirmed on computed tomography angiogram.

Cell viability evaluation of transdifferentiated endothelial-like cells by quantitative electron-probe X-ray microanalysis for tissue engineering.

Development of an efficient vascular substitute by tissue engineering is strongly dependent on endothelial cell viability. The aim of this study was to evaluate cell viability of transdifferentiated endothelial-like cells (Tr-ELC) by using for the first time electron probe X-ray microanalysis (EPXMA), not only to accurately analyze cell viability by quantifying the intracellular ionic concentrations, but also to establish their possible use in vascular tissue engineering protocols. Human umbilical cord Wharton's jelly stem cells (HWJSC) and endothelial cells from the human umbilical vein (HUVEC) were isolated and cultured.

Endovascular treatment of a symptomatic vertebral artery pseudoaneurysm.

A 35-year-old patient was brought to the emergency department referring dysarthria, left ear tinnitus for 5 min, and short-lasting blindness, with headache in the 45 min before the clinical presentation. In the magnetic resonance imaging, an acute-subacute lesion in the cerebellum right-anterior lobe (in the territory of the cerebellum anterior artery) and a dilatation near the ostium of the right vertebral artery were seen. For a better assessment, an Angio-CT was done, showing a 9-mm saccular pseudoaneurysm of the right vertebral artery close to the origin of the vessel, without being able to determine if it had been caused because of a dissection.

[Preliminary analysis of the relationship between peripheral arterial disease and other atherosclerosis markers and diabetic nephropathy].

Objectives: To determine lipid serum levels, lipoproteins and other markers related to nephropathy and peripheral arterial disease (PAD) in a type 2 diabetes population stratified according to their level of renal dysfunction.

Methods: A cross-sectional study was conducted on 72 type 2 diabetic patients followed-up in outpatient clinics. Patients were divided into 4 groups according to their estimated glomerular filtration rate (eGFR, mL/min) and albumin/creatinine ratio (ACR, mg/g) (eGFR > 60 and ACR < 30 [n = 23], eGFR > 60 and ACR > 30 [n = 12], eGFR30-60 [n = 23] and eGFR < 30 [n = 14]).

Femoro-saphenous arteriovenous access-related lower limb ischemia treated by distal arteries percutaneous angioplasty.

This is the first reported case of transposed femoro-saphenous angio-access complicated after four years by distal ischemia, which was successfully treated by percutaneous transluminal angioplasty (PTA) of the distal femoral and popliteal artery. Endovascular recanalization and angioplasty of the distal vessels offers a minimally invasive approach with preservation of the angio-access in these patients with high comorbidities.

Atypical Vascular Involvement in a Case of Behçet's Disease.

Introduction. Behçet's disease (BD) is a form of vasculitis of unknown etiology which is rare in our environment. It is characterized by a variety of clinical manifestations and usually affects young adults.

Femur ostochondroma and secondary pseudoaneurysm of the popliteal artery.

Osteochondroma is the most common skeletal benign tumour. It may present in a solitary form or as part of an autosomal dominant hereditary syndrome affecting several bones simultaneously. It is found most often in the knee region.
