The Contribution of Three-Dimensional Computerized Tomographic Angiography in the Head Positioning of the Patients with Middle Cerebral Artery Aneurysms.

Surgical intervention is a gold standard technique for ruptured and unruptured middle cerebral artery bifurcation aneurysm. Before surgical intervention it is necessary to know the three-dimensional shape, surgical position, projection and position of the aneurysm and the course of the parent artery. In a demonstrative case with middle cerebral artery aneurysm, using the OsiriX MD image processing software for DICOM images, it was demonstrated the position of the aneurysm neck, the projection of the aneurysm and the course of the M1 segment in relation with dynamic rotation and extension of the head. These dynamic videographic neuroradiological images may enhance the surgical anatomic perspective of the surgeon before the surgical intervention.
