BRACHO BLANCHET, Eduardo et al. Relaciones anatómicas de la vena subclavia en un grupo de recién nacidos con puntos de orientación óseos para su mejor punción con técnica infraclavicular y supraclavicular. Bol. Med. Hosp. Infant. Mex. [online]. 2004, vol.61, n.2, pp.134-140. ISSN 1665-1146.

Introduction. To correlate in an objective manner the anatomical differences of the subclavian vein in newborns for a better approach to it's puncture. Material and methods. A descriptive, surgical and pathological study in cadavers measuring the subclavian vein related to the clavicle and the sterno-clavicular joint. Results. The specific point where the subclavian vein cross the clavicle is lateral than the 1 reported in literature. The deepness of the vein with respect to the clavicle is 3.2 mm for the left side and 2 mm for the right, the ascending angle of the vein is 38° on the left and 34° on the right side. The highest point of the vein over the joint is 9 mm on the left and 7 mm on the right side. The descending angles of the vein are 27° on the left and 81° on the right side in average. Conclusions. We propose, based on our results, a puncture technique for the subclavian vein in newborns either with the supra or infraclavicular technique.
