ABSTRACT

Introduction: The transtemporal insonation with transcranial duplex sonography (TCDS) allows assessment of brain parenchyma structures, including the third ventricle.
Objective: To test the usefulness of TCDS to measure the third ventricle diameter in a sample of patients with different neurological illnesses.
Methods: It was selected a group of adult patients admitted to the stroke unit or sent to interconsultation and to whom by protocol a head CT scan was performed. The measurement of the diameter of the third ventricle was performed with TCDS and CT in axial planes. The results obtained by each technique and the linear correlation between the two measurements is presented.
Results: A total of 45 patients were included (mean age 59.6 years, 68.9% males). The third ventricle diameter increased with age. The diameter of the third ventricle increased with age. The average length (± SD) with the TCDS was 5.4 (2.3) mm and bt CT it was 5.6 (2.4) mm. The linear correlation between the values obtained by the two techniques was high (r = 0.93).
Conclusion: Transcranial duplex is a technique easy to perform and it has similar results in comparison with those obtained with the CT scan when the third ventricle size is measured.
