Abstract: Objective　To assess non-invasively the patterns of superficial veins at the cubital fossa of the right upper limbs by using vein imaging instrument.    Methods    The superficial vein angiography images of 1000 subjects in the cubital fossa of the right upper limbs were prospectively collected in our hospital from November 2018 to January 2019. Morphological types and dominant classification were performed.   Results  According to the morphology of the median cubital vein, they were divided into 5 types and 10 subtypes, which were I (I0, I1, I2), II, Ⅲ (Ⅲ0, Ⅲ1), Ⅳ (Ⅳ0, Ⅳ1, Ⅳ2) and V type, respectively. Among them, type I was accounting for 70.2%, type II was 2.9%, type III was 2.5%, type Ⅳ was 23.2%, type V was 1.2%. They were divided into the following three advantage types according to the diameter, angel and number of sub-branch of the main superficial vein in the area of cubital fossa, basilic advantage type (B type) accounting for 19.3%,   brachiocephalic advantage type (B type) accounting for 9.7%, median advantage type (M type) accounting for 71.0%.   There were statistical differences  in the gender (P<0.001), weight (P<0.001) and age  (P=0.003)  during the advantage classification. While there were statistical differences  in the gender (P<0.001) and  weight (P<0.001) the during the morphological classification.  There were statistical differences  in the diameter of basilic vein and basilic median vein in the subjects of different genders (P<0.001).  There were statistical differences in the diameter of basilic vein among different age group (P=0.009). There were  statistical differences in the diameter of brachiocephalic vein between the age of 31-50 years old and more than 70 years old (P=0.031).    Conclusions    Morphological classification can provide anatomic information of the superficial vein in the cubital fossa which can guide the vein related medical operation, and the advantage classification aims to better guide the vein selection of the upper extremity in the clinically relevant procedures (such as intravenous contract injection during enhanced CT examination)
