“…[ 8 9 ] The basilar venous plexus joins the inferior petrosal sinuses and the internal vertebral venous plexus during its course along the midline of the clivus and may also connect with the superior petrosal sinuses and cavernous sinuses at its caudal end. [ 10 11 ] Clival diploic veins connect the posterior intercavernous sinus and basilar plexus to anterior condylar veins. The plexus continues as the cavernous sinuses anterolaterally and basilar plexus inferiorly.…”

Retroclival epidural hematoma in adults is uncommon. Although most cases are associated with craniocervical trauma, other mechanisms have been reported, such as coagulopathy, vascular lesions, and pituitary apoplexy. We report two adults diagnosed with retroclival epidural hematoma. One patient was an 89-year-old male with leukemia and thrombocytopenia who sustained a fall and developed a traumatic retroclival epidural hematoma with brainstem compression; surgery could not be performed due to his clinical condition and he died 5 days later. The other patient was a 78-year-old female with atrial fibrillation who developed a spontaneous retroclival epidural hematoma as a result of warfarin use; she was treated conservatively with anticoagulant reversal and methylprednisolone and was subsequently discharged without neurological deficit. Retroclival hematomas are primarily treated conservatively due to the difficulty of surgical approach. The bleeding mechanism and dural and venous anatomy of this region tend to limit hematoma expansion.

“…Small intercavernous sinuses should be ligated with bipolar cautery prior to opening the dura, or they can be controlled with direct compression and hemostatic agents if they continue to bleed after cauterization. 21 Kim et al described the use of titanium clips to control large bleeding without delayed bleeding or postoperative complications related to clip placement postoperatively. In addition, they reported no significant clip artifact on postoperative imaging.…”

Background As expanded endoscopic endonasal approaches are gaining popularity, a thorough understanding of the anatomy of the intercavernous sinuses is pertinent to avoid bleeding complications. There have been few studies reporting the presence and dimensions of the anterior (AIS), posterior (PIS), and inferior (IIS) intercavernous sinuses. We performed a cadaveric study to better understand these structures. Methods Colored latex was injected into the arterial and venous trees of seventeen cadaveric heads. Dissections assessed the presence and dimensions of the anterior, posterior, and inferior intercavernous sinuses. In an additional 3 specimens, the sellar contents were subjected to histologic analysis. Results In thirteen specimens (59%), all three sinuses were identified. In 5 specimens (33%), only the anterior and posterior intercavernous sinuses could be identified, and in one specimen, only an anterior and inferior sinus were identified. An AIS was identified in all 20 (100%) specimens, PIS in 17 (85%), and an IIS in 13 (66)%. In two specimens (10%), the AIS covered the entire face of the sella. Dimensions of the AIS averaged 1.7 x 11.7 x 2.8 mm, PIS averaged 1.5 x 10.8 x 1.7 mm, and IIS averaged 8.7 x 11.8 x 1.0 mm when present. Conclusion All examined specimens demonstrated the presence of an anterior intercavernous sinus, and most had a posterior intercavernous sinus. The presence of an inferior intercavernous sinus was more variable. Preoperative awareness of these sinuses is helpful in planning transphenoidal surgery in order to minimize the risk of bleeding.

“…The superior petrosal vein (SPV) empties into the SPS 40 . The BP is located between the periosteal and meningeal layers of the clivus and communicates with the CS, SPS, and IPS 41 , 42 . The IPS drains venous blood from the PVC and the BP then empties into the junction of the sigmoid sinus and the superior jugular bulb 43 .…”

Petroclival region dural arteriovenous fistulas (DAVFs) are rare and difficult lesions to manage. They often have very complex anatomical structures and can be further divided into the superior petrosal sinus, petrous apex, inferior petrosal sinus, upper clival, and upper clival epidural-osseous DAVFs. Most petroclival region DAVFs should be treated due to their high Cognard grades. Currently, endovascular treatment (EVT) has become the first-line therapeutic option for petroclival region DAVFs. But not all the petroclival region DAVFs could be cured with EVT. When the arterial feeders are large or the DAVF is adjacent to the venous sinus, the success rate may be higher. In petroclival region DAVFs, if EVT can be performed successfully, satisfactory outcome can be anticipated. However, there are some inadvertent complications, which include cranial nerve palsy, subsequent sinus thrombosis, and migration embolization of the internal carotid artery and vertebral artery. Currently, a review of the EVT of petroclival region DAVFs is lacking. In this article, we performed a review of the relevant literature on this issue. In addition, some illustrative cases would be provided to elaborate these specific entities.
