3. IntroductionIncreased risk of venous thromboembolism is well recognized in patient with human immunodeficiency virus (HIV), and the dis-ease has been suggested to represent a pre-thrombotic state. Even so, little exist in literature concerning arterial thromboembolism causing upper arm ischemia in patients with HIV. We report a case report of acute embolic occlusion of non-diseased brachial and axillary artery in a 42 years old man with HIV infection.
