Description

<p>Objectives: We investigated the relation between success placement of central venous (CV) port and anatomical factors associated with left brachiocephalic vein (LBV) stenosis. Methods: One hundred forty-nine patients who underwent CV port placement were included from Jan. 2014 to Dec. 2017 in our institution. All patients performed CT scan prior to CV port placement. We investigated the diameter of LBV, the distance between sternum and aorta, and the curving angle of LBV around aorta. We compared them with success rate of CV catheter insertion. Results: CV catheter insertion was failed in 9.5% of patients who received CV catheter insertion from left side. In the failure group of CV catheter insertion, the diameter of LBV, the distance between sternum and aorta, and the curving angle of LBV around aorta were significantly smaller than in the success group. Conclusions: Success rate of CV catheter insertion was associated with LBV stenosis, the distance between sternum and aorta, and the curving angle of LBV around aorta.</p>
