title: [Morphometric study with imaging techniques of Trolard's vein and its anastomosis to the superior longitudinal sinus].
abstract: OBJECTIVE
  The main objective of this work is to allow the anatomical localization of the vein of Trolard (VT) or great anastomotic vein, before neurosurgical approaches to the parietal region.
  
  
  METHODS
  Thirty four patients were subjected to cerebral angiography. Measurements of different points related to the anatomy of the vein were taken in 41 studies on the lateral projection. A statistical analysis was performed.
  
  
  CONCLUSIONS
  The measures obtained are of practical utility to locate the final portion of the vein of Trolard in its anastomotis to the sagittal superior sinus (SLS) for planning neurosurgical approaches to the parietal region.
