Is There Any Association Between the Jugular and Sigmoid Notch Areas and Intracranial Hemorrhage Side?

Abstract

Purpose: To evaluate the association between the side of the spontaneous intracranial hemorrhage (sICH) and the jugular and sigmoid notch areas. Methods: A total of 265 patients (111 women and 154 men) with a mean age of 68.8±11.7 years (range between 50 to 90 years) and with sICH, were retrospectively enrolled. Control group harbored 45 patients (19 women and 26 men) with a mean age of 68.3±11.9 years (range between 50 to 90 years). Jugular and sigmoid notch areas were measured on axial plane CT images, for both the right and left side in the study and control groups. The association between ICH and sigmoid/jugular notch areas were assessed by student t test. The correlation between right/left sigmoid and right/left jugular notch areas were assessed by Pearson correlation. Results: There was a significant difference between right and left sigmoid/jugular notch areas in patients with right sided ICH (P<0.001) and left sided ICH (P<0.001) There was a significant difference between right and left sigmoid/jugular notch areas in patients with right sided ICH (P<0.001) and left sided ICH (P<0.001). No significant difference was found in terms of right sigmoid and right jugular notch areas between patients with right sided ICH and control group (P=0.156 and P=0.483, respectively). No significant difference was detected in terms of left sigmoid and left jugular notch areas between patients with left sided ICH and control group (P=0.118 and P=0.449, respectively). Conclusion: There was no direct association between the sigmoid and jugular notch areas and intracranial hemorrhage side.
