Upper extremity superficial vein thrombophlebitis (UESVT) is relatively common. The imaging criterion of UESVT is that the upper extremity superfine-fiber venous segment is incompressible on ultrasonic images.The 339 included patients involved 118 tumor-bearing patients and 221 non-tumor patients. The occurrence rate of thrombophlebitis among the tumor-bearing patients was 6.7%, which was significantly lower than that among the non-tumor patients (18.5%). However, this result is inconsistent with another study that the incidence rate of thrombophlebitis is higher among tumor-bearing patients.Collin J et alThis study still has some limitations. First, this is a single-center study, which may cause bias, so multi-center collaborative research is needed to validate our findings. Second, the sample size is relatively small, so our findings shall be further validated. Finally, the included patients suffer tumors and lung infection, so patients of other diseases are needed to confirm our results.
