Histological and biochemical modifications after aneurysm endograft exclusion are still unclear. We describe a new model of endograft implantation on a murine aneurysm. Through thrombus analysis with and without persistant circulating blood stream interface, and new endovascular biomaterials evaluation, this model will help to better understand endovascular aneurysm exclusion pathobiology.

Surgery is the gold standard for accessible arteriovenious malformations (AVMs), and pre-operative embolization can simplify this procedure. We describe our approach for staged endovascular embolization and open resection of AVMs, and provide a representative clinical example highlighting the advantages of a comprehensively trained neurovascular surgeon leading a multi-disciplinary clinical team.

Overview of DNA Repair

In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage. Chemically...
FAQs
The stent graft creates a reinforced channel along the diseased aortic segment, guiding blood through the graft rather than against a weakened aneurysm wall or through a dissection entry tear. By excluding the abnormal area from direct circulation, the repair can reduce stress on the affected segment and lower the risk of rupture in appropriately selected cases.
Imaging allows clinicians to guide the catheter and confirm that the collapsible stent graft reaches the intended thoracic aortic segment. It also helps assess deployment and graft position immediately after placement. Without this visual guidance, the team could not reliably verify that the graft covers the diseased area or seals the relevant entry point.
For an aneurysm, the graft excludes the enlarged segment from blood flow. In a dissection, it is positioned to seal an entry tear and redirect flow through a reinforced channel. Selected traumatic aortic injuries may also be treated by covering the damaged region. Thus, the same platform addresses different structural problems through disease-specific placement.
The procedure begins with catheter access through an artery, typically in the groin. Clinicians advance the delivery system toward the affected thoracic aortic segment under imaging guidance. They then release the compressed stent graft so it expands against the aortic wall, creating the new channel. Imaging confirms its location and relationship to the diseased region.
TEVAR may provide an alternative to open surgery for selected diseases of the thoracic aorta, including aneurysms, dissections, and certain traumatic injuries. Its catheter-based approach is particularly relevant when clinicians seek to treat the affected segment without directly opening the chest. Suitability depends on the specific aortic problem and whether the graft can be positioned appropriately.
Follow-up imaging monitors whether the graft remains correctly positioned and whether the aorta shows expected remodeling, meaning structural change after blood flow has been redirected. Surveillance also seeks evidence of potential complications. These assessments are important because successful treatment depends not only on deployment, but also on maintaining an effective seal and stable repair over time.
