First Report of Interaction Among Ponticulus Posticus Anomaly and Stenosis of Carotid, Vertebral Arteries

In humans, body asymmetry might affect vascular asymmetry. This study aimed to examine whether there is a relationship between side asymmetry and the presence of ponticulus posticus (PP) anomaly, carotid, and vertebral artery stenosis. Retrospective analysis was done on the data files of patients with carotid and vertebral arteries who were admitted to our hospital between November 2018 and December 2022 for the presence of PP anomaly. There were 31 patients (25 males and 6 females, with a median age as 69.54 years (range 51-84 years). PP anomaly was detected in 11 of 31 patients (31.48% of cases). The correlation test showed that the presence of PP was negatively correlated with carotid stenosis on the right side, but there was no such correlation on the left. This study demonstrated that there is an innovative anatomical correlation between the PP anomaly and carotid stenosis in the adult patient cohort.
