A case of aneurysm of the jugular and mediastinal veins radioisotopic blood pool study of venous aneurysm

Venous aneurysm not associated with other cardiovascular disease or trauma is a rare condition. A case is present of bilateral jugular and mediastinal venous aneurysm, which was detected and depicted to a full extent by means of a blood-pool study with sup(99m)Tc-fibrinogen, undertaken because of concurrent thrombocytopenia. The aneurysm was confirmed by subsequent X-ray angiography and surgery. In radioisotopic blood pool study venous aneurysm, unlike arterial or aortic aneurysm, may be filled to the equilibrium state later than the appearance of the cardiac pool. (orig.)
