Commentary: Computational Biomechanics-Based Rupture Prediction of Abdominal Aortic Aneurysms.

Computational Hemodynamics of Abdominal Aortic Aneurysms

An existing computational model is extended to simulate Newtonian and non-Newtonian blood flow in three dimensional idealized abdominal aortic aneurysm (AAA) geometries in order to calculate the wall shear stress (WSS) and wall shear stress gradient (WSSG) along the arterial wall and obtain the velocity profile. From these, the locations of high and low WSS and WSSG can be determined, as well a...

A Review of Computational Methods to Predict the Risk of Rupture of Abdominal Aortic Aneurysms

Computational methods have played an important role in health care in recent years, as determining parameters that affect a certain medical condition is not possible in experimental conditions in many cases. Computational fluid dynamics (CFD) methods have been used to accurately determine the nature of blood flow in the cardiovascular and nervous systems and air flow in the respiratory system, ...

Seasonal variations in the rupture of abdominal aortic aneurysms.

From 1982 to 1994, 54 patients (47 men; mean age 72 years) were referred to the Hospital of Ferrara, Italy for spontaneous rupture of abdominal aortic aneurysm. Sixteen died in the emergency department and 38 underwent urgent surgery. Day and month of onset of acute symptoms leading to urgent surgery were recorded. A seasonal variation with significant peaks in spring and autumn was found. Thes...

Analysis and computer program for rupture-risk prediction of abdominal aortic aneurysms

BACKGROUND Ruptured abdominal aortic aneurysms (AAAs) are the 13th leading cause of death in the United States. While AAA rupture may occur without significant warning, its risk assessment is generally based on critical values of the maximum AAA diameter (> 5 cm) and AAA-growth rate (> 0.5 cm/year). These criteria may be insufficient for reliable AAA-rupture risk assessment especially when pred...
