Analysis of morphological parameters to differentiate rupture status in anterior communicating artery aneurysms.

In contrast to size, the association of morphological characteristics of intracranial aneurysms with rupture has not been established in a systematic manner. We present an analysis of the morphological variables that are associated with rupture in anterior communicating artery aneurysms to determine...
