Aortic aneurysm, the pathological dilatation of the aorta at distinct locations, can be attributed to many different genetic and environmental factors. The resulting pathobiological disturbances generate a complex interplay of processes affecting cells and extracellular molecules of the tunica interna, media and externa. In short, aortic aneurysm can affect processes involving the extracellular matrix, lipid trafficking/atherosclerosis, vascular smooth muscle cells, inflammation, platelets and intraluminal thrombus formation, as well as various endothelial functions.

Intraluminal prosthetic graft thrombus (IPT) has been described in case of endovascular aortic pathology repair. This study aimed to assess hemodynamic indicators associated with various anatomical morphologies following endovascular aortic repair (EVAR), aiming to offer further references for the choice of clinical therapy. Six model models (normal, iliac compression, aortic compression, aortoiliac compression, iliac distortion, and long-leg stent) were established based on common anatomical morphologies following EVAR.

Purpose: In managing type 2 endoleak (T2EL) following endovascular aortic aneurysm repair (EVAR), an indication for reintervention is aneurysm enlargement (AnE). A previous study found that low D-dimer levels (DDLs) at 1 year were associated with reduced AnE risk in patients with persistent T2ELs (pT2ELs). This study analyzed patients with pT2ELs to determine the correlation between DDLs at annual follow-ups and AnE and proposed a follow-up protocol incorporating DDL monitoring.

Article Synopsis
- A 63-year-old man experienced a loss of consciousness due to hemolytic anemia eight years after urgent surgery for aortic dissection.
- Contrast-enhanced CT scans showed severe issues with the ascending aortic graft, including flexion and stenosis, leading to complications.
- A successful thoracic endovascular aortic repair (stent-graft implantation) improved the condition, resolved the anemia, and highlighted a less invasive alternative to traditional surgery for similar cases.
Endovascular removal of a symptomatic intracranial foreign body via contact aspiration: illustrative case.

Background: With the growing utilization of general endovascular techniques, iatrogenic endovascular foreign bodies have become more prevalent. Contact aspiration has proven to be a valuable technique in treating ischemic strokes by removing the intraluminal thrombus causing cerebral perfusion deficits and neurological symptoms. The authors present a case of the removal of a foreign body from the vasculature via contact aspiration, which had embolized in a delayed fashion after aortic valve replacement.
