Abdominal aortic aneurysm (AAA) is a life-threatening condition characterized by the dilation of the abdominal aorta, leading to a high risk of rupture. Current treatment options are limited, particularly for patients ineligible for surgical interventions. This study explores a novel immunotherapeutic approach using chimeric antigen receptor Treg cells targeting vascular cell adhesion molecule-1 (VCAM-1) to mitigate AAA progression.

Objective: Carotid paragangliomas (CPGLs) are rare neuroendocrine tumours. Previous studies have emphasised the high prevalence of hereditary genetic variants. This study specifically examined the clinical course of CPGLs in patients with pathogenic disease causing genetic variants (PV) and non-specific non-pathogenic genetic findings (non-PV) currently not associated with CPGLs.

Background: The transcription factor (erythroblast transformation-specific-related gene) has been identified as a key regulator of vascular function by suppressing inflammation in endothelial cells (ECs). Dysregulation of due to genetic risk variants is linked to chronic inflammation in conditions such as atherosclerosis and aortic aneurysms.

Case Presentation: This research work investigates the role of the gene in the development of a systemic arterial aneurysm manifestation.

Pulmonary artery dissection (PAD) is a rare, life-threatening condition requiring prompt diagnosis and treatment. We present a case of ruptured left PAD originating from an acute type B aortic dissection (aTBAD) through a persistent ductus arteriosus Botalli (PDA) in an otherwise healthy 29-year-old man. The patient was successfully treated by means of thoracic endovascular aortic repair (TEVAR) alone.

Objective: Biomechanical modeling of infrarenal aortic aneurysms seeks to predict ruptures in advance, thereby reducing aneurysm-related deaths. As individual methods focusing on strain and stress analysis lack adequate discretization power, this study aims to explore multifactorial characterization for progressive aneurysmal degeneration. The study's objective is to compare stress- and strain-related parameters in infrarenal aortic aneurysms.

The aim of this study was to investigate histopathological differences in abdominal aortic aneurysms (AAAs) between patients with multiple and single arterial aneurysms, as we suspect that there are different underlying mechanisms in aneurysm formation. Analysis was based on a previous retrospective study on patients with multiple arterial aneurysms (; defined as at least four, = 143) and a single AAA (, = 972) who were admitted to our hospital for treatment between 2006 and 2016. Available paraffin-embedded AAA wall specimens were derived from the Vascular Biomaterial Bank Heidelberg (, = 12 vs.

Background: Although patients with multiple arterial dissections in distinct arterial regions rarely present with known connective tissue syndromes, we hypothesized that mild connective tissue abnormalities are common findings in these patients.

Methods: From a consecutive register of 322 patients with cervical artery dissection (CeAD), we identified and analyzed 4 patients with a history of additional dissections in other vascular beds. In three patients, dermal connective tissue was examined by electron microscopy.

Aortic diseases comprise aneurysms, dissections, and several other pathologies. In general, aging is associated with a slow but progressive dilation of the aorta, along with increased stiffness and pulse pressure. The progression of aortic disease is characterized by subclinical development or acute presentation.

Background: Stanford type B aortic dissection is a rare, life-threatening complex phenotype associated with several modifiable and genetic risk factors. In the current study of a hospital-based, consecutive series of aortic dissection patients we propose a selection based on age and family history of aortic disease for genetic testing and detection of causative gene variants.

Methods: In this single center cohort study from 2013 to 2018 patients with acute Stanford type B aortic dissections were consecutively treated and analyzed by next generation sequencing based on selection criteria (age of disease onset ≤45 years and/or positive familial history for aortic disease) to detect genome-wide pathogenic variants in protein-coding sequences and to identify large copy number variants (CNV).

Background and Purpose- We sought to explore the effect of genetic imbalance on functional outcome after ischemic stroke (IS). Methods- Copy number variation was identified in high-density single-nucleotide polymorphism microarray data of IS patients from the CADISP (Cervical Artery Dissection and Ischemic Stroke Patients) and SiGN (Stroke Genetics Network)/GISCOME (Genetics of Ischaemic Stroke Functional Outcome) networks. Genetic imbalance, defined as total number of protein-coding genes affected by copy number variations in an individual, was compared between patients with favorable (modified Rankin Scale score of 0-2) and unfavorable (modified Rankin Scale score of ≥3) outcome after 3 months.
