Using an illustrative case, this report reviews the entity of primary upper-extremity deep venous thrombosis, also known as Paget-Schroetter syndrome. The entity of Paget-Schroetter syndrome is important to military physicians because of its occurrence in young, healthy, active individuals such as those in our active duty population. A review of the literature was performed and it was concluded that a multimodal approach to therapy, as was done in this case, gives the best overall results.
