Direct drainage of the basal vein of Rosenthal into the Superior Petrosal Sinus: a literature review.
Anatomy & cell biology, 2020Co-Authors: Santiago Gutierrez, Joe Iwanaga, Aaron S. Dumont, R. Shane TubbsAbstract:An adult male was found to have a variation of the left basal vein of Rosenthal after presenting with complaints of headache and balance issues. In this case, the vein drained directly into the left Superior Petrosal Sinus (SPS) instead of the great vein of Galen. Anatomical variation of the basal vein is likely due to embryonic development of the deep cerebral venous system as primitive structures either differentiate regress or further with age. These changes may result in the uncommon presentation seen in this case. To our knowledge, this is the first case that shows the basal vein drains into the SPS. The normal and variant anatomy of this vessel are discussed.

The Superior Petrosal Sinus
Anatomy Imaging and Surgery of the Intracranial Dural Venous Sinuses, 2020Co-Authors: Seleipiri Akobo, R. Shane TubbsAbstract:Abstract The Superior Petrosal Sinus emerges from the posteroSuperior aspect of the cavernous Sinus and runs caudally beneath the oculomotor and trochlear nerves and along the dorsal ridge of the petrous part of the temporal bone, on which it leaves a small depressed groove, where the tentorium cerebelli is attached to the petrous ridge. The Superior Petrosal Sinus also traverses the Superior aspect of the trigeminal ganglion in the roof of Meckel's cave. This chapter details the anatomy, variants, and clinical implications of this Sinus.

The Superior Petrosal Sinus: a review of anatomy, embryology, pathology, and neurosurgical relevance
Neurosurgical Review, 2018Co-Authors: Martin M. Mortazavi, Marcus A. Cox, Erfanul Saker, Sanjay Krishnamurthy, Ketan Verma, Christoph J. Griessenauer, Marios Loukas, Rod J. Oskouian, R. Shane TubbsAbstract:The Superior Petrosal Sinus is located between the middle and posterior cranial fossae and is important during many neurosurgical approaches to the skull base. Using standard search engines, the anatomical and clinical importance of the Superior Petrosal Sinus was investigated. The Superior Petrosal Sinus is important in many neurosurgical approaches and pathological entities. Therefore, it is important for those who operate at the skull base or interpret imaging here to have a good working knowledge of its anatomy, development, and pathological involvement.

The relationship between the Superior Petrosal Sinus and the porus trigeminus: an anatomical study.
Journal of neurosurgery, 2013Co-Authors: R. Shane Tubbs, Martin M. Mortazavi, Sanjay Krishnamurthy, Ketan Verma, Christoph J. Griessenauer, Aaron A. Cohen-gadolAbstract:Object During intracranial approaches to the skull base, vascular relationships are important. One relationship that has received scant attention in the literature is that between the Superior Petrosal Sinus (SPS) and the opening of the Meckel cave (that is, the porus trigeminus). Methods Cadaver dissections were performed in 25 latex-injected adult cadaveric heads (50 sides). Specifically, the relationship between the SPS and the opening of the Meckel cave was observed. The goal was to enhance knowledge of the relationship between the SPS and the opening of the Meckel cave. Results Of the 50 sides, 68%, 18%, and 16% of SPSs traveled Superior to, inferior to, and around the opening to the Meckel cave, respectively. In the latter cases, a venous ring was formed around the proximal trigeminal nerve. No Sinus entered the Meckel cave. In general, the porus trigeminus was narrowed on sides found to have an SPS that encircled this region. Sinuses that traveled only inferior to the porus were in general smaller ...

the use of fibrin glue to stop venous bleeding in the epidural space vertebral venous plexus and anterior cavernous Sinus technical note
Neurosurgery, 2007Co-Authors: Laligam N Sekhar, Sabareesh K Natarajan, Thomas C Manning, Dolin BhagawatiAbstract:Objective Various techniques have been used to stop venous bleeding from the epidural space, vertebral venous plexus, and cavernous Sinus. Here, we describe our experience with the use of fibrin glue to stop venous bleeding in these areas. Methods During the last 8 years, the senior author (LNS) has used injection of Tisseel fibrin glue (Baxter Healthcare Corp., Deerfield, IL) into the epidural space (n = 200 patients), anterior cavernous Sinus (n = 46 patients), vertebral venous plexus (n = 20 patients), and Superior Petrosal Sinus (n = 20 patients) to assist in hemostasis. The technical nuances are illustrated in three videos. Results Injection of fibrin glue in the epidural space, anterior cavernous Sinus, and vertebral venous plexus yielded good results in assisting with hemostasis. Two patients experienced complications caused by occlusion of veins draining the brainstem after fibrin glue was injected into the Superior Petrosal Sinus. Conclusion Fibrin glue injection is an excellent option for hemostasis in the epidural space, anterior cavernous Sinus, and vertebral venous plexus. However, based on our experience, fibrin glue injection into the Superior Petrosal Sinus is not recommended.

The subtemporal, transcavernous, anterior transPetrosal approach to the upper brain stem and clivus.
Journal of neurosurgery, 1992Co-Authors: Griffith R. Harsh, Laligam N SekharAbstract:The temporal lobe, posterolateral cavernous Sinus, tentorium, and petrous apex restrict anterolateral surgical access to lesions of the upper brain stem and clivus. The authors describe a modified transPetrosal approach that enhances the exposure of clival chordomas and aneurysms of the basilar artery bifurcation. An intradural and extradural subtemporal approach is combined with division of the tentorium and Superior Petrosal Sinus, posterolateral dissection of the cavernous Sinus, and intradural removal of the petrous bone from its apex to the cochlea. The indications, advantages, and disadvantages of this subtemporal, transcavernous, anterior transPetrosal approach are described in detail, along with its use in six patients.

Superior semicircular canal dehiscence syndrome
Journal of Neurosurgery, 2017Co-Authors: Ryan Brewster, Daniel J. Lee, Dennis S Poe, David M Vernick, Eduardo C Corrales, Ian F DunnAbstract:Superior semicircular canal dehiscence (SSCD) syndrome is an increasingly recognized cause of vestibular and/or auditory symptoms in both adults and children. These symptoms are believed to result from the presence of a pathological mobile “third window” into the labyrinth due to deficiency in the osseous shell, leading to inadvertent hydroacoustic transmissions through the cochlea and labyrinth. The most common bony defect of the Superior canal is found over the arcuate eminence, with rare cases involving the posteromedial limb of the Superior canal associated with the Superior Petrosal Sinus. Operative intervention is indicated for intractable or debilitating symptoms that persist despite conservative management and vestibular sedation. Surgical repair can be accomplished by reconstruction or plugging of the bony defect or reinforcement of the round window through a variety of operative approaches. The authors review the etiology, pathophysiology, presentation, diagnosis, surgical options, and outcomes ...

Superior Canal Dehiscence Syndrome Associated With the Superior Petrosal Sinus in Pediatric and Adult Patients
Otology & neurotology : official publication of the American Otological Society American Neurotology Society [and] European Academy of Otology and Neu, 2011Co-Authors: Andrew A. Mccall, Michael J. Mckenna, Saumil N. Merchant, Hugh D. Curtin, Daniel J. LeeAbstract:Objective: To determine whether pediatric and adult patients with Superior canal dehiscence (SCD) at the Superior Petrosal Sinus (SPS) develop Superior canal dehiscence syndrome (SCDS). Study Design: Retrospective review. Setting: Tertiary care academic medical center. Patients: Pediatric and adult patients with SPS-associated SCD were identified from a database of 131 patients with SCD based on high-resolution temporal bone computed tomography. Intervention: One pediatric patient experienced incapacitating exercise-induced vertigo, and this patient's Superior semicircular canal defect was plugged via a transmastoid approach. The 11 remaining patients were managed by observation. Main Outcome Measure: Clinical symptoms and signs, audiologic testing, vestibular evoked myogenic potentials, and radiologic data. Results: Twelve patients, aged 15 to 84 years, with SCD caused by the SPS contacting the Superior semicircular canal were identified. The most characteristic clinical feature in this population (5/12) was dizziness related to exercise and exertion. Bilateral SCD was observed in 3 patients. Eleven patients did not have severe symptoms and were managed conservatively. One patient, aged 15, required surgical intervention for incapacitating vertigo and experienced relief of symptoms with reversal of diagnostic indicators postoperatively. This is the first reported surgical repair of SCDS in a pediatric patient. Conclusion: This is the first series of patients who have SCDS due to contact of the SPS with the Superior semicircular canal. Exercise and exertion-related symptoms are common in patients who have SCD owing to this cause. Transmastoid Superior canal plugging is feasible and successful in treating SCDS in the pediatric patient.

Absence of the Superior Petrosal veins and Sinus: Surgical considerations.
Surgical neurology international, 2015Co-Authors: Ken Matsushima, H. Kiyosue, Eduardo Carvalhal Ribas, Noritaka Komune, Koichi Miki, Albert L. RhotonAbstract:Background: The Superior Petrosal vein, one of the most constant and largest drainage pathways in the posterior fossa, may result in complications if occluded. This study calls attention to a unique variant in which the Superior Petrosal veins and Sinus were absent unilaterally, and the venous drainage was through the galenic and tentorial drainage groups. Methods: This study examines one venogram and another anatomic specimen in which the Superior Petrosal vein and Sinus were absent. Results: The Superior Petrosal veins, described as 1-3 bridging veins, emptying into the Superior Petrosal Sinus, are the major drainage pathways of the Petrosal group of posterior fossa veins. In the cases presented, the Superior Petrosal vein and Sinus were absent and venous drainage was through the galenic and tentorial groups, including the lateral mesencephalic or bridging vein on the tentorial cerebellar surface. Conclusions: In cases in which the Superior Petrosal Sinus and veins are absent, care should be directed to preserving the collateral drainage through the galenic and tentorial tributaries. Although surgical strategies for intraoperative management and preservation of venous structures are still controversial, knowledge of the possible anatomical variations is considered to be essential to improve surgical outcomes.

classification of the Superior Petrosal veins and Sinus based on drainage pattern
Neurosurgery, 2014Co-Authors: Ken Matsushima, Kohei Inoue, Toshio Matsushima, Yuji Kodama, Yoshihiro Kuga, Hideyuki Ohnishi, Albert L. RhotonAbstract:BACKGROUND: The increasing number of reports of complications after sacrificing the Superior Petrosal veins, the largest veins in the posterior fossa, has led to a need for an increased understanding of the anatomy of these veins and the Superior Petrosal Sinus into which they empty. OBJECTIVE: To examine the anatomy of the Superior Petrosal veins and their size, draining area, and tributaries, as well as the anatomic variations of the Superior Petrosal Sinus. METHOD: Injected cadaveric cerebellopontine angles and 3-dimensional multifusion angiography images were examined. RESULTS: The 4 groups of the Superior Petrosal veins based on their tributaries, course, and draining areas are the Petrosal, posterior mesencephalic, anterior pontomesencephalic, and tentorial groups. The largest group was the Petrosal group. Its largest tributary, the vein of the cerebellopontine fissure, was usually identifiable in the suprafloccular cistern located above the flocculus on the lateral surface of the middle cerebellar peduncle. The medial or lateral segment of the Superior Petrosal Sinus was absent in 40% of cerebellopontine angles studied with venography. CONCLUSION: The Superior Petrosal veins and their largest tributaries, especially the vein of the cerebellopontine fissure, should be preserved if possible. Obliteration of Superior Petrosal Sinuses in which either the lateral or medial portion is absent may result in loss of the drainage pathway of the Superior Petrosal veins. Preoperative assessment of the Superior Petrosal Sinus should be considered before transPetrosal surgery in which the Superior Petrosal Sinus may be obliterated.

Microsurgical anatomy of the Superior Petrosal venous complex: new classifications and implications for subtemporal transtentorial and retrosigmoid suprameatal approaches.
Journal of neurosurgery, 2007Co-Authors: Necmettin Tanriover, Albert L. Rhoton, Hiroshi Abe, Masatou Kawashima, Galip Zihni Sanus, Ziya AkarAbstract:Object The purpose of this study was to define the patterns of drainage of the Superior Petrosal venous complex (SPVC) along the petrous ridge in relation to the Meckel cave and internal acoustic meatus (IAM) and to delineate its effect on the surgical exposures obtained in subtemporal transtentorial and retrosigmoid suprameatal approaches. Methods The patterns of drainage of the SPVC along the petrous ridge were characterized according to their relation to the Meckel cave and the IAM based on an examination of 30 hemispheres. Subtemporal transtentorial and retro-sigmoid suprameatal approaches were performed in three additional cadavers to demonstrate the effect of the drainage pattern on the surgical exposures. Conclusions The SPVC emptied into the Superior Petrosal Sinus (SPS) within a distance of 1 cm from the midpoint of the Meckel cave. The patterns of drainage of the SPVC were classified into three groups. Type I emptied into the SPS above and lateral to the boundaries of the IAM. The most common ty...
