Persistent trigeminal artery: an anatomical study.
The Australian and New Zealand Journal of Surgery
|August 1, 1985
Summary
This study details three persistent trigeminal arteries (PTA), anatomical variants connecting the carotid and basilar systems. Understanding their unique pathways through the cavernous sinus is crucial for clinical insights.
Area of Science:
- Neuroanatomy
- Vascular Anatomy
- Cranial Nerves
Background:
- The persistent trigeminal artery (PTA) is a rare embryological remnant.
- Variations in PTA course can impact neurovascular structures within the skull base.
Purpose of the Study:
- To provide a detailed anatomical description of three cases of persistent trigeminal arteries (PTA).
- To discuss the clinical significance of observed PTA anatomical variations.
Main Methods:
- Anatomical dissection of three human cadavers.
- Detailed observation and documentation of the course of the persistent trigeminal arteries.
Main Results:
- Two PTAs connected the carotid and basilar systems via the cavernous sinus, situated between the posterior clinoid process and the trigeminal nerve.
- One PTA traversed the dorsum sellae, entering the pituitary fossa floor.
Conclusions:
- The anatomical course of the PTA can vary significantly.
- These variations have potential implications for neurosurgical procedures and understanding cerebrovascular flow patterns.
