Superficial definition and meaning | Collins English.

The incidence of superficial thrombophlebitis (STP) in the general population ranges from 3% to 11%, 1-5 although this is considered to be an underestimate as only the more symptomatic cases seek medical attention. The mean age at STP presentation is 60 years 3,6-12 and the older the patient is the fewer the risk factors required for its development. 11,13 STP is more common (50%-70%) in women and prevalence increases with age. 3,6,7,11,12,14-21

STP involves the greater saphenous system more often (60-80%) than the lesser saphenous system (10%-20%). 3,11,22,23 When STP develops in patients with varicose veins it is confined to the varicose tributaries rather than the saphenous trunks. 3,14 The prevalence of STP in patients with varicose veins ranges from 4%-59%; 3,11,14,15,23 bilateral SPT is reported in 5%-10% of patients. 3,6,11,23,24 Several factors including obesity, 3,25-31 age, and protein-S deficiency are associated with SPT in patients with varicose veins. 32

late 14c., in anatomical and mathematical uses, "of or relating to a surface," from Latin superficialis "of or pertaining to the surface," from superficies "surface," from super "above, over" (see super- ) + facies "form, face" (see face (n.)). Meaning "not deep, without thorough understanding, cursory" (of perceptions, thoughts, etc.) first recorded early 15c. (implied in superficially "not thoroughly").
