Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Abdominal Aortic Aneurysm Type II Endoleaks

Journal of Cardiovascular Diseases & Diagnosis, 2016
Type II endoleaks occur commonly following endovascular aneurysm repair (EVAR). Although they remain enigmatic, multiples studies have evaluated preoperative risk factors and strategies for prevention of type II endoleaks. Prophylactic treatment of type II endoleaks can include embolization of accessory arteries, as well as complete aneurysmal sac ...

Mixed Reality‐Assisted Thoracic Endovascular Aortic Repair: A Retrospective Study on Efficacy and Safety

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
This study demonstrates the significant clinical utility of Mixed Reality (MR) in Thoracic Endovascular Aortic Repair (TEVAR). Our findings reveal that MR‐assisted workflows enhance patient comprehension and satisfaction preoperatively and provide intuitive intraoperative navigation.

Adverse Hemodynamics in Kommerell's Diverticulum: A Comparative Case Report Linking Oscillatory Shear Index to Aortic Dissection

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Hemodynamic evaluation using four‐dimensional flow magnetic resonance imaging or computational fluid dynamics can identify a high‐risk phenotype in Kommerell's diverticulum, which is characterized by intradiverticular vortex formation, low wall shear stress, and elevated oscillatory shear index (OSI).

Type IIIB endoleak from stent suture lines of a thoracic endograft

Journal of Vascular Surgery Cases and Innovative Techniques, 2019
We report a case of a patient with type IIIB endoleak after thoracic endovascular aortic repair that remained undetected by computed tomography and was first diagnosed during open conversion surgery.

Percutaneous direct thrombin injection with hydrodissection to manage type II endoleak after endovascular abdominal aortic aneurysm repair [PDF]

, 2018
Type II endoleak is the most common complication after endovascular abdominal aortic aneurysm repair (EVAR). The management remains controversial. We present a case in which endoleak was successfully treated by direct percutaneous thrombin injection with

Intractable Delayed Bleeding After Endoscopic Submucosal Dissection for Early Gastric Cancer in Patients With Chronic Disseminated Intravascular Coagulation Caused by Aortic Aneurysm

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Chronic disseminated intravascular coagulation (DIC) is a rare complication of an aortic aneurysm (AA), and it may go unnoticed because patients are often asymptomatic. The condition is sometimes first recognized when trauma or an invasive procedure triggers a sudden and severe difficulty in achieving hemostasis.
