INTRODUCTION: Percutaneous tracheostomy procedures are commonplace in intensive care units worldwide. Haemorrhagic complications, though potentially fatal, are thought to be under-reported. Ultrasonography use has not established itself in these procedures. This study assesses the prevalence and characteristics of pre-tracheal blood vessels, to aid intensivists on potential procedural hazards. METHOD: A retrospective, observational study was performed in the UK. Computed tomography angiograms from January 2012 to October 2014 were randomly retrieved and analysed for vessel data. RESULTS: A total of 343 adult patients were included (mean age: 65 (inter-quartile range 52-79), male: 63%). Forty-one percent of patients demonstrated a vessel overlying percutaneous tracheostomy insertion sites (C6-T1); veins were more common than arteries (69%, p = 0.001). Males were more likely to display veins (78 vs. 53%, p < 0.001). DISCUSSION: A substantial proportion of patients exhibited pre-tracheal vessels. Front-of-neck ultrasonography has huge potential to identify these. Based on these data, we believe ultrasonography may be an effective screening tool for percutaneous tracheostomy procedures to reduce complications. Further research is required to study outcomes.
