Pressure distribution on the wall of experimental aneurysms

Acta Neurochir (Wien). 1978;45(1-2):27-34. doi: 10.1007/BF01774381.


Since it is known that turbulent flow exists in aneurysms, we have investigated whether pressure might be distributed unevenly on the aneurysmal wall, and whether it varies with the shape and size of the aneurysm and its orifice diameter as well as with the direction of blood flow in the parent vessel. It was found that in some instances, such as with aneurysms having narrow necks and situated at 90 degrees to the parent vessel blood flow, aneurysmal pressure is relatively low.
