[The blood vessels of the posterior cranial fossa. anatomy, pathophysiology, clinic--a survey (author's transl)].

Pathophysiology and tomography of the blood vessels of the posterior cranial fossa gain clinical interest in treatment of diseases of the inner ear, complications of middle ear inflammations, tumors of the pyramid and cerebello-pontine angle. Numerous variations in the arterial venous system restrict neuroradiological procedures. Techniques to treat a thrombosis of the sinuses were developed 50 years ago. Surgical procedures to remove glomus tumors of the pyramid could be improved by new anatomical and surgical experiences. Unilateral neck dissection occasionally alters the blood flow in the sinuses of the posterior cranial fossa causing serious complications.
