Small whitish bodies called Pacchionian granulations grow out of the arachnoid (middle) membrane. Dr. Ney’s belief is that man’s upright posture conditions the growth of Pacchionian granulations.

Successful percutaneous transvenous deployment of a miniature valved biomimetic transdural endovascular shunt (CereVasc eShunt, Auburndale, MA, USA) via an inferior petrosal sinus approach was ...

Hydrocephalus, a disorder of excess cerebrospinal fluid, affects roughly 1 in 500 live births per year. Communicating, or extra-ventricular hydrocephalus, is a subset of the disorder that is, in part, ...

It can be adjusted by intracranial membrane tension patterns, which are broadcast by the falx cerebri and tentorium cerebelli to an aggregation of arachnoid granulation bodies. 2 The craniosacral ...

Perhaps arachnoid granulations act as safety valves (suggested by successful insertion of small CSF-dural-venous valves to treat hydrocephalus 13) rather than main drainage routes.

Arachnoid granulations in the cranial bones are found only around the superior sagittal sinus, for the first time at the age of 10, and over time their number increases significantly. From the age of ...

The purpose of this study was to investigate using light microscopy the fibro-cellular components of arachnoid granulations affected by mild and severe subarachnoid hemorrage. The erythrocytes were in ...

Compared with arachnoid granulation, the nodule consists of smooth muscle fibers and higher rate of elastic fibers. Understanding the detailed anatomy of the straight sinus may help surgeons to avoid ...

We could see arachnoid granulations without erythrocytes, which cells showed big round nucleous suggesting their transformation into phagocytic cells. Key words: arachnoid granulation, subarachnoid ...

In this case, flow is most likely blocked at the arachnoid granulations resulting in communicating hydrocephalus. This picture requires emergency neurosurgery and ventricular shunting.
