To systematicallyinvestigate this landmark, we conducted a study in four phases:1 Two blindfolded examiners determined the distance betweenthe tuberosity's medial border and the clavicle's lateral endin 100 dried clavicles and then 2 performed subclavian veincannulation in 20 fresh human cadavers using the tuberosityand the suprasternal notch as landmarks. 3 Three-dimensionalreconstructions of the subclavian artery and vein and surroundingstructures were derived from computed tomography datasets of10 patients. The length of the path of a virtual subclavianvein cannulation with the deltoid tuberosity landmark was measuredbilaterally. 4 In a prospective, randomized trial, subclavianvein cannulation was performed in 60 patients with a standardapproach or with the deltoid tuberosity as landmark.
