The traumatic rupture of the aortic isthmus is one of the worst complication due to high speed motor vehicle accidents. When death is not the immediate consequence of this lesion, the initial clinical signs are not very clear. The present article demonstrates the case of a 23-year-old patient, victim of a car accident. A traumatic aortic rupture was actually diagnosed after the unusual discovery of a mesenteric infarct. In this case report, the mesenteric infarct mechanism can be controversed, and an emphasis should be put on an early aortic lesion diagnosis and repair in order to avoid any ischaemic complications.

Aortic dilatation is a severe pathology that increases the risk of rupture and its hemodynamics could be accurately assessed by using the 4D flow cardiovascular magnetic resonance (CMR) technique but flow assessment under complex flow patterns require validation. The aim of this work was to develop an in vitro system compatible with CMR to assess the accuracy of volume flow measurements in dilated aortas. Approach.

Type B aortic dissection (TBAD) represents a serious medical emergency with up to a 50% associated 5-year mortality caused by thoracic aorta, dissection-associated aneurysmal (DAA) degeneration, and rupture. Unfortunately, conventional size-related diagnostic methods cannot distinguish high-risk DAAs that benefit from surgical intervention from stable DAAs. Our goal is to use DAA stiffness measured with magnetic resonance elastography (MRE) as a biomarker to distinguish high-risk DAAs from stable DAAs.

Background: Abdominal aortic aneurysm (AAA) is characterized by the proteolytic breakdown of the extracellular matrix, leading to dilatation of the aorta and increased risk of rupture. Biomarkers that can predict major adverse aortic events (MAAEs) are needed to risk stratify patients for more rigorous medical treatment and potential earlier surgical intervention.
Objectives: The primary objective was to identify the association between baseline levels of these biomarkers and MAAEs over a period of 5 years.

Introduction: Management of patients with large aortic arch aneurysms who are considered high risk for frozen elephant trunk technique have been challenging, especially when they have a dilated ascending aorta (AA) that precludes total endovascular branched repair (arch BEVAR). A viable option in our armamentarium is wrapping of the AA (AW), and zone 0 Ishimaru TEVAR.
Methods: Retrospective analysis of our aortic database from 2013 to 2024 to select high-risk patients with aortic arch aneurysm that had an AW and TEVAR.
Most thoracic aortic aneurysms (TAAs) are asymptomatic and often diagnosed at the time of rupture. TAAs involving the proximal arch require adequate coverage with thoracic endovascular aortic repair, which is timely and challenging in emergent ruptures. In situ laser fenestration is a novel method of arch revascularization.
