Intercavernous Venous Communications in the Human Skull Base

Analysis of the intercavernous sinuses using multidetector computed tomography digital subtraction venography (CT-DSV)

“…Although there were some studies concerning the ICSs using cadavers [2,7,10], there is no established method for radiological evaluation of the ICSs. Therefore, in the present study, we evaluated the ICSs using computed tomography digital subtraction venography (CT-DSV) and analyzed the results.…”

“…Subsequent studies [2][3][4][5][6][7] revealed that the intercavernous sinuses (ICSs) ran across the midline and were located between the meningeal dural layer and osseous dural layer in the sella turcica. The three ICSs were therefore named the anterior, inferior, and posterior ICS (AICS, IICS, PICS).…”

Intercavernous Sinus Dural Arteriovenous Fistula Treated with Transvenous Coil Embolization: A Case Report

“…Such cases require a bilateral angiographic study [5]. In our case, we had bilateral ocular signs; we believe that in similar cases where bilateral ocular symptoms are so marked, the possibility of a primary lesion of the intercavernous sinuses is high and provokes the interventionist to search more deeply for an intercavernous primary site for the fistulous communication.…”

The role of bilateral inferior petrosal sinus sampling in the diagnostic evaluation of cushing’s disease

“…They are interconnected by four intercavernous pathways. The anterior and posterior intercavernous sinuses are present in all people and run in front of and behind the pituitary (24). The inferior intercavernous sinus, coursing along the sellar floor between the anterior and posterior pituitary lobes, is absent in a small number of people; however, it is usually present in three forms (plexuslike, venous lake, and mixed).…”

“…The inferior intercavernous sinus, coursing along the sellar floor between the anterior and posterior pituitary lobes, is absent in a small number of people; however, it is usually present in three forms (plexuslike, venous lake, and mixed). Finally, the basilar plexus is present in all people, is located along the dorsum sellae, and is the largest interconnection in most cases (24).…”
