Archiv und Atlas der normalen und pathologischen Anatomie in typischen Röntgenbildern. Die kombinierte Enzephal-Arteriographie

This work emanates from the surgical clinic of the state hospital at Magdeburg-Altstadt under the direction of Professor Löhr and from the state neurologic clinic at Magdeburg-Sudenburg under the direction of Professor Jacobi. The collaboration of these eminent authors has resulted in a distinct advance in the diagnostic methods relating to cranial lesions. The dangers of the method are recognized as being similar to but no greater than those attending encephalography and ventriculography. The authors prefer the introduction of air into the ventricular system through a lumbar puncture rather than its introduction into a ventricular puncture. Thorium dioxide sol is used as the opaque substance for arteriography. The authors' technic for the injection is described. A 5 cm. incision is made over the anterior upper border of the sternocleidomastoid muscle down to the internal carotid artery. The needle is introduced quietly for about 1.5 cm. and the roentgenograms made during
