Large caliber blood vessel pseudoaneurysm following prosthetic surgery. Mathematical model and numerical considerations [PDF]

INCAS Bulletin, 2016
Using a non-Newtonian mathematical model for the blood flow and a generalized Maxwell model for the viscoelastic behavior of the large vessels – elaborated and presented already by us in previous papers [1], [2] we make some remarks on the wall shear ...

Bilateral Brachial Artery Aneurysms with Distal Embolisms in a Patient with Prolonged Crutch Compression

Vascular Specialist International, 2021
Chronic axillary crutch use may lead to axillary or brachial artery aneurysms and associated axillobrachial thromboembolic complications. Most of these aneurysms remain asymptomatic and undiagnosed until a complication occurs.
