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 ...

Impending rupture of abdominal aortic aneurysm due to spontaneous obstruction of aortocaval fistula after endovascular abdominal aortic aneurysm repair

Journal of Vascular Surgery Cases and Innovative Techniques, 2021
Endovascular aortic aneurysm repair (EVAR) is a valid treatment for patients with abdominal aortic aneurysm with aortocaval fistula. However, an endoleak can be caused by persistent communication between the aneurysm and the inferior vena cava.

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).

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.

A novel approach for treating type II endoleaks utilizing contrast-enhanced ultrasound

Journal of Vascular Surgery Cases and Innovative Techniques, 2021
Endoleaks are a frequent and well-known complication after endovascular repair of aortic aneurysms. An endoleak can lead to increased intrasac pressure, sac enlargement, and potential aneurysm rupture.

Treatment of Coronary Perforation in a Bifurcation: Two‐Stent Strategies With Fenestrated Covered Stents

Catheterization and Cardiovascular Interventions, Volume 107, Issue 4, Page 1080-1087, March 1, 2026.
ABSTRACT Coronary perforations are a dreaded complication for any interventional cardiologist. The treatment of this complication is exceptionally difficult when it occurs in a coronary bifurcation. While a conservative approach or a balloon occlusion might be sufficient in some cases, additional treatment is sometimes necessary.
