2023年11月3日 · The main function of the sigmoid sinus is to conduct blood from the transverse sinus to the internal jugular vein. Along the way, the sigmoid sinus receives tributaries that collect blood from the pericranial veins, and in some cases …

The transverse sinuses (left and right lateral sinuses), within the human head, are two areas beneath the brain which allow blood to drain from the back of the head. They run laterally in a groove along the interior surface of the occipital bone.

2024年6月17日 · In turn, the sigmoid sinuses continue as the jugular bulbs in the skull base. The transverse sinuses exhibit highly variable anatomy, which at times makes imaging evaluation of them, in those with possible dural venous sinus thrombosis, very difficult. For example, one study demonstrated 1:

2023年11月3日 · Anatomy and function of the transverse sinus. The transverse sinus (lateral sinus) is a paired venous vessel that runs through the tentorium cerebelli. Both sinuses begin at the internal occipital protuberance of occipital bone, while they terminate by giving off the ipsilateral sigmoid sinus.

The transverse sinus is a dural venous sinus present in the posterior aspect of the cranium. We report an unusual variant of this sinus with the presence of a fenestration at its proximal segment. We will review and discuss the background and the …

2018年1月20日 · The sigmoid and transverse sinus both vary in size. The sigmoid sinus is a dural venous sinus that lies deep within the human head, and just below the brain. A dural sinus is a channel that...

The sigmoid sinuses (sigma- or s-shaped hollow curve), also known as the pars sigmoid, are paired dural venous sinuses within the skull that receive blood from posterior transverse sinuses. The sigmoid sinus is a dural venous sinus situated within the dura mater.

2023年11月5日 · The transverse sinus, also known as the lateral sinus, is an anatomical structure within the human brain. Its primary function lies in the drainage of deoxygenated blood and cerebrospinal fluid, essential for maintaining proper cerebral circulation and fluid balance.

2025年1月23日 · At its lateral extremity, the transverse sinus curves downward to become the sigmoid sinus. This transition occurs near the petrous part of the temporal bone and forms an S-shaped path before leading to the jugular foramen, where the sigmoid sinus continues as the internal jugular vein.

2016年5月10日 · Venous sinus pathology can result in multiple pathological diseases, including idiopathic intracranial hypertension (IIH). There remains a paucity of information on anatomical luminal variations of the major venous sinuses which …
