The laterocavernous sinus system is best defined as the entire territory served by the laterocavernous and the superior petrosal sinuses (SPS).
The laterocavernous sinus is a small but important venous structure located between the two dural layers forming the lateral wall of the cavernous sinus and has been described as one of the principal drainage pathways of the deep and superficial middle cerebral veins.
Several disease processes in the head involve the laterocavernous sinus. To evaluate and treat these diseases it is necessary for neuroradiologists not only to know selective angiography and embolization techniques, but also the territory of the laterocavernous sinus and venous watershed between the deep and superficial venous systems.
In the present report the normal angiographic anatomy of the laterocavernous sinus system, its relationship with the deep and superficial venous systems, and its importance in clinical situations are outlined.
海绵窦外侧壁系统最好被定义为由海绵窦外侧壁和岩上窦（SPS）所供应的整个区域。
海绵窦是一个小但重要的静脉结构，位于形成海绵窦外侧壁的两层硬脑膜之间，被描述为大脑深、浅静脉的主要引流途径之一。
头部的几种疾病过程涉及海绵窦外侧壁。为了评估和治疗这些疾病，神经放射学家不仅需要了解选择性血管造影和栓塞技术，还需要了解海绵窦外侧壁的范围以及深、浅静脉系统之间的静脉分水岭。
在本报告中，概述了海绵窦外侧壁系统的正常血管造影解剖、与深、浅静脉系统的关系及其在临床情况下的重要性。
