✓ The dura mater of the posterior cranial fossa of 86 adult human cadavers has been examined grossly after the injection of India ink through the confluence of sinuses in order to visualize the extent, communications, and tributaries of the straight sinus. Variations from the textbook description of formation by the union of the inferior sagittal sinus and the great cerebral vein are described and discussed.

✓ The authors report a variety of arrangements of the venous channels comprising the straight sinus (sinus rectus) and its connections during a continuing study of the cerebral sinuses and their tributaries. In approximately 85% of 131 specimens of dura mater with enclosed venous sinuses derived from fresh cadavers, the straight sinus was represented by a single midline tentorial channel whereas in the remaining 15%, segments of it were doubled and in a few, tripled. In addition to these aberrations in the development of the main trunk of this sinus, the venous patterns at the junctions of the inferior sagittal sinus, vein of Galen and straight sinus showed comparable developmental inconstancies. Also in no specimens were the patterns of venous channels in the leaves of the tentorium cerebelli alike. The course, size, and connections of all the tributaries of the straight sinus have been studied and consideration given to their potentials as collateral pathways in the event either the vein of Galen or the straight sinus itself were occluded.

✓ Dural arteriovenous malformations (AVMs) are considered to be acquired lesions that develop secondary to venous obstruction, which sometimes happens in head trauma. However, there has been a report of an anterior cranial fossa dural AVM that occurred independently of a history of head trauma, and there has been speculation that these malformations are congenital. The authors recount their experience with a patient who had an anterior cranial fossa dural AVM that was discovered incidentally. The lesion was fed by the bilateral anterior ethmoidal arteries and drained into the superior sagittal sinus via frontal cortical veins. The patient had a history of severe head trauma that had occurred 30 years earlier. This is the first case report in which a previous head trauma is strongly believed to be the cause of an anterior cranial fossa dural AVM. The authors postulate that anterior cranial fossa dural AVMs can develop secondary to a head trauma.

✓ Among 880 specimens of cerebral dura mater with enclosed sinuses, one had a sharply delineated bulbous conformation of the distal segment of a superior cerebral vein. There was no evidence of an arteriovenous malformation. Early plaque formation was present in the inner aspect of the thick wall of the dilated segment of vein.

✓ The authors describe the use of autogenetic posterior atlantooccipital (PAO) membrane for duraplasty following after posterior cranial fossa surgery. The PAO membrane is routinely exposed for procedures of the posterior cranial fossa and merely needs to be dissected free of the underlying dura mater. Recently this membrane was obtained in several pediatric patients following procedures of the posterior cranial fossa such as duraplasty in case of Chiari I malformation. No postoperative complications were found at 6-month follow-up examination. The advantages of this intervention include less manipulation of muscle and fascia than that involved in other procedures and, therefore, seemingly less postoperative pain and the negation of issues inherent with foreign-body graft sources. The authors believe this structure to be of use as a dural substitute in small dural openings of the posterior cranial fossa.

Object. Chordae willisii are structures located in the lumen of the superior sagittal sinus (SSS). It is thought that they act as flow-improving structures within the sinuses. There are few anatomical descriptions of chordae willisii, and all previous observations were performed through standard anatomical dissections. The purpose of this study was to visualize and describe structural and topographical features of the chordae willisii with the aid of rigid endoscopy. Methods. Twenty-five SSSs obtained from fresh human cadavers during autopsies were the material for this study. Specimens were flushed with tap water to remove clots. Bridging veins emptying into the sinus were ligated, and continuous flow of a saline solution through the sinus in a physiological direction was achieved by connecting the sinus to an irrigating system. Rigid endoscopes of different diameters (2.7–4.5 mm) and optic (0 and 30°) were inserted into the lumen of the sinus. The endoscope was connected to a digital camera and a video system to allow for recording of the observed structures. Finally, the sinuses were opened and the chordae willisii were dissected using standard anatomical methods. The chordae willisii were observed in all examined specimens. Three different types of the cords were found: lamellar, trabecular, and valvelike types. The most common type was the valvelike (mixed) one, which comprised 45.1% of all cords. The chordae willisii were most commonly observed in the parietooccipital region of the SSS. Conclusions. Witout disturbing any structural relationships, the use of endoscopy allowed visualization and description of intraluminal structures as they behaved physiologically.

✓ The meningeal vasculature of the posterior cranial fossa was studied on injected normal anatomical specimens and in angiograms of patients with posterior fossa meningiomas. The correlated results indicate that the dura anterior to the foramen magnum is supplied by meningeal vessels from the carotid siphon, the ascending pharyngeal and middle meningeal arteries. The dura posterior to the foramen magnum is supplied primarily by the occipital artery and secondarily by the vertebral artery.
