Abstract:

BACKGROUND: The adjacent data between clavicle and the subclavian vessels mostly come from human observation and measurement of anatomical specimens. The measurement results slightly differ from the actual body.
OBJECTIVE: To observe and analyze the relationship between the clavicle peripheral vascular in vivo and anatomy of collarbone for finding the safe area and hazardous area of screw external fixation.
METHODS: Totally 44 patients were conducted chest and neck enhanced CT scanning to examine coronary angiography. The collected CT image of clavicle area were used to reconstruct three-dimensional images of intact clavicle and clavicle peripheral vascular using ADW4.4 workstation. The adjacent relationship between the clavicle and clavicle peripheral vascular was observed and measured on the images.
RESULTS AND CONCLUSION: Subclavian vein and artery near the clavicle, clavicle angle formed between the lower edge of the left was (53.75°±10.64°), the right side was (52.85±11.41)°. If the length of the clavicle was divided into five equal parts, the clavicle artery and vein at the surface of the clavicle in its projected range from the inside out about the second 1/5 of the left brachiocephalic vein from the clavicle shortest average distance (4.81±1.66) mm, the right innominate artery shortest distance from the average of the clavicle was (5.09±2.60) mm. In vivo imaging measurements are closer to the normal human body, clavicle surgery is likely to damage the site of the subclavian vessels from the inside out of the second 1/5 of the sternum and clavicle end, to grasp the anatomical characteristics of the source can be maximum avoided health peripheral vascular injuries of the clavicle.
