[The slightly different neck pain].

Thrombosis of the jugular vein and upper extremities are much rarer than thrombosis of the lower extremities. The diagnostic tool of choice is duplex sonography of the vessels. A thorough clarification of the cause is necessary after diagnosis if an obvious cause is not initially found. The focus here should be on searching for malignancy as well as hypercoaguability. The recommended minimum duration of anticoagulation with low-molecular-weight heparin is at least 3 months for primary thromboses of the upper extremities and 6 months for secondary thromboses. Rivaroxaban therapy is also a suitable option for outpatient management.
