Spontaneous venous thrombosis is rare clinical condition without the presence of additional risk factors. Spontaneous arterial thrombosis is even rarer than venous thrombosis. Splenectomy is known to be risk factor for venous thromboembolism, postoperative deep venous thrombosis, and pulmonary thromboembolism. Paradoxical embolism defines the thrombus originating from venous circulatory system transvers to arterial bed through interatrial, interventricular, or arteriopulmonary shunt. Systemic embolism in the absence of known intracardiac or carotid disease raises the suspicion of right-sided source.
