When selective catheterization of a common carotid artery is difficult, it is still possible to obtain adequate diagnostic films of the cerebral circulation in the lateral projection without marked superimposition of the intracranial vessels. This can be achieved angiographically by using digital recording after an arterial aortic arch injection and compressing the opposite carotid artery during imaging.
当颈总动脉的选择性插管困难时，仍有可能在侧位投照中获得足够的脑循环诊断性影像，而颅内血管无明显重叠。这可以通过动脉主动脉弓注射后使用数字记录并在成像过程中压迫对侧颈动脉来在血管造影上实现。
