Left brachiocephalic venous thrombus initially presenting as acute aortic syndrome.

Upper extremity deep venous thrombosis (UEDVT) is rare but carries significant morbidity. Primary UEDVT presents non-specifically and there are no clear diagnostic or management guidelines, which are essential for early treatment to prevent potentially devastating complications such as pulmonary embolus or post-thrombotic pain syndrome. A patient with left brachiocephalic vein UEDVT initially diagnosed radiographically as an acute aortic syndrome and referred to a cardiothoracic unit is presented. Computed tomography venogram confirmed the diagnosis of UEDVT and therapeutic anticoagulation was started. This case highlights the need for validated diagnostic and management algorithms for UEDVT. Furthermore, this relatively rare condition should be considered for patients with acute chest pain and abnormal imaging referred to surgical units.
