Cannavale A, Corona M, Nardis P, et al. - In order to investigate CT angiography findings of head and neck tumours in predicting carotid blow out syndrome (CBS), researchers retrospectively examined the records of individuals with head and neck cancer who underwent invasive angiography for CBS at our Institution from July 2013 to 2019. This study recruited a sum of 24 individuals who underwent routine CT angiogram neck and embolization for CBS were included in this study. Univariate logistic regression revealed as 360-degree involvement of target vessel may significantly raise the risk of bleeding, along with T stage. It was noted that tumour necrosis and calibre vessel reduction were quite influential, but not significantly. Moreover, contingency table analysis detected 360-degree vessel involvement with the highest sensitivity and PPV in prognosticating bleeding. The results suggested that CT angiography imaging findings have the potential to distinguish individuals with head and neck cancer at higher risk of bleeding.
