Hand acceleration time (HAT) as a diagnostic tool in the assessment of haemodialysis access-induced distal ischaemia (HAIDI): study protocol for a prospective cohort study in the Barcelona south metropolitan area.

Introduction: Chronic hand ischaemia may affect some haemodialysis patients with an arteriovenous fistula (AVF) or graft (AVG), a condition known as haemodialysis access-induced distal ischaemia (HAIDI). Duplex ultrasonography (DUS) can provide comprehensive insights into anatomical and perfusion properties, and measuring the hand acceleration time (HAT) has been demonstrated to be sensitive within the framework of chronic upper limb ischaemia.

Methods And Analysis: This single-centre, prospective cohort study will involve adult end-stage renal disease (ESRD) patients requiring either AVF or AVG for haemodialysis.

Duplex ultrasound as a single imaging test for Global Limb Anatomic Staging System assignment stage and comparison with intraoperative arteriography.

Objective: Obtaining a prognostic and predictive classification based on the risk of amputation is crucial in ischemic pathology of the lower limbs. Accurate anatomical characterization of arterial lesions is essential for optimal clinical decision-making. The Global Limb Anatomic Staging System (GLASS) provides a comprehensive anatomy assessment of the femoropopliteal and infrapopliteal arterial system.

Radiation Exposure in Endovascular Surgery According to Complexity: Protocol for a Prospective Observational Study.

In the past decades, we have witnessed tremendous developments in endovascular surgery. Nowadays, highly complex procedures are performed by minimally invasive means. A key point is equipment improvement.

Multicenter Comparative Analysis of Late Open Conversion in Patients With Adherence and Nonadherence to Instructions for Use Endovascular Aneurysm Repair.

Purpose: The widespread adoption of endovascular aneurysm repair (EVAR) as preferred treatment modality for abdominal aortic aneurysm (AAA) has enlarged the number of patients needing open surgical conversion (OSC). The relationship between adherence to Instructions For Use (IFU) and EVAR long-term outcomes remains controversial. The aim of this study is to compare preoperative differences and postoperative outcomes between EVAR patients not adjusted to IFU and adjusted to IFU who underwent OSC.

COVID-19 and aorto-enteric fistula.

We present the case of a 72-year-old male with upper gastrointestinal bleeding. He had been discharged from hospital two weeks before after severe COVID-19 infection, treated with lopinavir-ritonavir (L-R), hydroxychloroquine, tocilizumab, and methylprednisolone. On presentation, he was in hypovolemic shock.

National Diagnostic Reference Levels for Endovascular Aneurysm Repair and Optimisation Strategies.

Objective: The International Commission on Radiological Protection (ICRP) has highlighted the large number of medical specialties using fluoroscopy outside imaging departments without programmes of radiation protection (RP) for patients and staff. Vascular surgery is one of these specialties and endovascular aneurysm repair (EVAR) is one of the most challenging procedures requiring RP guidance and optimisation actions. The recent European Directive on Basic Safety Standards requires the use and regular update of diagnostic reference levels (DRL) for interventional procedures.

Endovascular Treatment of Descending Thoracic Aortic Pathology: Results of the Regis-TEVAR Study.

Background: Endovascular techniques have become an essential tool for treatment of thoracic aortic pathology. The objective of this study was to analyze indications and results of thoracic endovascular aortic repair (TEVAR) in vascular surgery units, through a retrospective and multicentric national registry called Regis-TEVAR.

Methods: From 2012 to 2016, a total of 287 patients from 11 vascular surgery units, treated urgently and electively, were recruited consecutively.

Contrast-Induced Nephropathy: A Fact or Fiction in Lower Limb Revascularization?

Introduction: Contrast-induced nephropathy (CIN) is defined as an increase >25% of serum creatinine from baseline, occurring in 24-48 hours after exposure to contrast, while alternative explanations for renal impairment have been excluded. The volume administered directly relates to risk, increasing by 12% per 100 mL of contrast. According to the series, its incidence varies between 3.
