Role of the blood vessel and arachnoid as conflicting structures during microvascular decompression for treating typical trigeminal neuralgia

Conclusion The tightness of the junction between the offending artery and the trigeminal nerve may represent a major factor affecting different postoperative outcomes following MVD. An offending artery may be attached to the arachnoid thickening, resulting in a neurovascular compressive effect, whereas the role of venous contact as a cause of TN remains debatable.
