Deep venous thrombosis after shoulder arthroscopy.

Deep venous thrombosis after shoulder arthroscopy is so unusual that its occurrence should arouse the suspicion of (a) a hypercoagulable state, or (b) a pathologic extrinsic mass causing venous occlusion. This case of deep venous thrombosis after shoulder arthroscopy led to the discovery of previously asymptomatic Hodgkin's lymphoma that was compressing the innominate vein.
