More Details: Background Bleeding incidents during percutaneous dilatational tracheostomy are concerning, and most cases occur in patients with unrecognized and unanticipated anatomical variations in the vascular anatomy. However, the extent of this variation remains unclear. To address this knowledge gap, our study aimed to comprehensively map laryngeal vascular anatomy in a cohort of adult patients. Methods Ultrasound assessments of the soft tissue in the neck were performed, spanning from the thyroid cartilage to the third tracheal ring and extending 2 cm laterally on both sidesperformed. We subdivided this area into 12 zones comprising four medial and eight lateral sections. A pre-planned form was used to document the presence of arteries or veins in each zone. The results are reported as odds ratios, 95% CIs, and corresponding P values. Results Five-hundred patients were enrolled from August 14, 2023, to November 13, 2023, at the University Hospital of Padua. Arteries and veins were identified in all investigated zones (varying from a minimum of 1.0%–46.4%). The presence of invessels progressively increased from the cricothyroid membrane to the third tracheal ring and from the midline to the paramedian laryngeal area. Conclusions Given the prevalence of arteries and veins, particularly in areas where tracheostomies are commonly performed, we strongly advocate for routine ultrasound assessments before such procedures are performed.
