- A fusiform aneurysm bulges or balloons out an artery on all sides (pictured below). If this aneurysm occurs in an aorta, the internal radius may increase from r₁ = 1.1 cm in the normal, healthy section to 12= = 2.2 cm in the diseased section (while staying at the same vertical height). The speed of blood m flow is v₁ = 0.42 in the normal section and the gauge pressure P₁ is 99.98 mmHg.
