Distribución de los patrones venosos de la fosa cubital en una muestra de personas nacidas en Bucaramanga, Colombia

The rational use of access to the superficial veins in the cubital fossa is particularly important in pediatric patients, with fistulas for dialysis, chemotherapy, or central venous access routes. Several venous patterns have been described for their benefits or risks. The prevalence of venous patterns in a population of both sexes born in Bucaramanga, Colombia, in 800 upper limbs (200 men and 200 women), according to the classification proposed by del Sol et al. (1988, 2007). The descriptive analysis for nominal and ordinal qualitative variables with percentages, the quantitative mean and standard deviation for normally distributed variables and nonparametric identified by number using median and interquartile range, was compared by gender and venous pattern through test and chi square Kwallis. The predominant pattern was III, 297 cases (37%) determined by a high frequency in women (54%), followed by II 190 cases (24%). On the right side for both sexes the most common pattern was III, 141 cases (35%), followed by II, 89 cases (22%). On the left side for both genders predominant pattern III, 156 cases (39%), followed by the second with 101 cases (25%). Pattern II was greater in men (28%), followed by III (21%). In women the pattern III predominated, followed by II (19%). On the right side in men, II predominated (24%) followed by IV (23%). On the right side III predominated in women (51%) followed by II (20%). On the left side in men, the predominant pattern II (32%) followed by III (21%). On the left side in women predominated III (57%) followed by II (18%). The pattern appeared more often at the same time on both sides in the same person was III (16.6%).
