ANEURYSMS OF THE POSTERIOR COMMUNICATING ARTERY: HEMODYNAMICS AND SHAPES

摘要

The anatomic subtype of PcomA aneurysms includes a wide variety of flow patterns, shapes and sizes. Flow types become more complicated with increasing size and complexity of shape. Ruptured aneurysms had larger maximum wall shear stress on average than unruptured aneurysms. These findings are consistent with previous analysis of the broader group of cerebral aneurysms and previous subtype analysis of anterior communicating aneurysms [4, 5].
