Anatomy of the inferior petro-occipital vein and its relation to the base of the skull: Application to surgical and endovascular procedures of the skull base.

Shane Tubbs R1, Watanabe K, Loukas M, Cohen-Gadol AA.Author information 1Pediatric Neurosurgery, Children's Hospital, Birmingham, Alabama.AbstractAlthough the inferior petro-occipital vein has been recently used for vascular access to the cavernous sinus, few detailed descriptions of its anatomy are in the literature. We aimed to investigate the morphology and relationships of this vessel. Twelve latex-injected cadaveric heads (24 sides) were dissected to identify the inferior petro-occipital vein and anatomic details documented. The petro-occipital vein was identified on 83.3% of sides. Generally this vein united the internal carotid venous plexus to the superior jugular bulb. However, on 10% of sides, the anterior part of this vein communicated directly with the cavernous sinus, and on 15%, the posterior vein drained into the inferior petrosal sinus at its termination into the superior jugular bulb. The petro-occipital vein was separated from the overlying inferior petrosal sinus by a thin plate of bone. On 40% of sides, small venous connections were found between these two venous structures. The vein was usually larger if a nondominant transverse sinus was present. The overlying inferior petrosal sinus was smaller in diameter when an underlying inferior petro-occipital vein was present. On 20% of sides, the posterior aspect of the vein communicated with the hypoglossal canal veins. On three sides, diploic veins from the clivus drained into the inferior petro-occipital vein. The inferior petro-occipital vein is present in most humans. This primarily extracranial vessel communicates with intracranial venous sinuses and should be considered an emissary vein. Knowledge of this vessel's exact anatomy may be useful to cranial base surgeons and endovascular specialists. Clin. Anat., 2013. © 2013 Wiley Periodicals, Inc.

Dural arteriovenous fistula on the convexity presenting with pure acute subdural hematoma.

Ogawa K1, Oishi M, Mizutani T, Maejima S, Mori T.Author information 1Department of Neurology, Nihon University School of Medicine, Nerimahikarigaoka Hospital, Tokyo, Japan. ogawak@med.nihon-u.ac.jpAbstractNon-traumatic dural arteriovenous fistula/malformation (dural AVF/AVM) presenting with pure subdural hematoma (SDH) is relatively rare. We report on a male patient who showed pure acute SDH and was diagnosed as having dural AVF on the convexity near the superior sagittal sinus (SSS), based on angiographic findings. A 27-year-old man was admitted to our hospital due to headache with acute onset. The patient did not have a history of head trauma or injury. Head CT showed an abnormal high-density area on the surface of the cerebral hemisphere on the left side, indicating acute SDH. Angiography during the arterial phase demonstrated that an abnormal artery originating from the left occipital artery was connected with a dural vein and a diploic vein on the convexity near the SSS. We concluded that a dural AVF existed at this area, and that the dural AVF had caused the acute SDH. Dural AVF/AVM which causes non-traumatic SDH is usually accompanied by intracerebral hemorrhage (ICH) and/or subarachnoid hemorrhage (SAH). In contrast, non-traumatic dural AVF/AVM presenting with pure SDH is rare, and our patient represents such a rare case. We should consider dural AVF/AVM and perform angiography if necessary when we encounter a patient showing non-traumatic SDH without ICH and/or SAH.
