Overview
Pathophysiology
Physiology
The normal physiology of bridging veins can be understood as follows:[1]
- In embryonic period, there is lots of anastomosis between brain and dura matter venous drainage.
- After 12 weeks of gestation these anastomosis will disappear and what is left from them create bridging veins.
- These vein s will drain venous blood from underlying brain tissue to the dural sinuses.
- Rupture of these bridging vein (mostly due to head trauma) will result in hemorrhage between dura matter and arachnoid, and leads to subdural hematoma.
Pathogenesis
- It is understood that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3]
Genetics
[Disease name] is transmitted in [mode of genetic transmission] pattern.
OR
Genes involved in the pathogenesis of [disease name] include:
- [Gene1]
- [Gene2]
- [Gene3]
OR
The development of [disease name] is the result of multiple genetic mutations such as:
- [Mutation 1]
- [Mutation 2]
- [Mutation 3]
Associated Conditions
Conditions associated with [disease name] include:
- [Condition 1]
- [Condition 2]
- [Condition 3]
Gross Pathology
On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Microscopic Pathology
On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
