sodium-pertechnetate-tc-99m and Aneurysm

The case of a 14-year-old girl with Behcet syndrome is described. Besides painful and recurrent oral ulcerations, the patient had a cough and intermittent hemoptysis. The initial chest roentgenogram revealed bilateral parahilar opacities. CT and MRI scans of the thorax showed bilateral thrombosing aneurysms of the pulmonary arteries. Pulmonary blood flow imaging was performed after technegas ventilation lung scanning and Tc-99m MAA injection using a first-pass radionuclide angiography procedure. Altered blood flow in the left pulmonary artery was shown. Bilateral and well-defined ventilation/perfusion mismatched areas suggested a high probability of pulmonary embolism. Little additional information was obtained on subsequent contrast pulmonary angiography. The high incidence of pulmonary artery hypertension and associated vascular injury risk makes pulmonary angiography an unsafe procedure in patients with pulmonary Behcet syndrome. The need for pulmonary angiography could be obviated in such cases with the use of high-precision MRI and ventilation/perfusion lung scanning, including radionuclide pulmonary angiography.

An extremely rare vascular complication, carotid artery aneurysm, developed 60 years after a torticollis operation. The patient's internal jugular vein was completely obstructed proximal to the subclavian vein. There was an associated incomplete obstruction of the ipsilateral common carotid artery on the right aspect of the neck--the site where resection of the whole sternocleidomastoid muscle had been performed when she was one year old. The patient had audible bruits over the right common carotid at the base of her neck but no signs of occlusive cerebrovascular disease. The diagnosis was made mainly with use of technetium radionuclide angiography. To the authors' knowledge, this is the first such report in the English or German literature.

Radionuclide angiography and ultrasonic echolocation were used for the examination of 38 patients with aneurysms. Isotope angiography was fulfilled in all the 38 patients, ultrasonography was used in 20 patients. Radionuclide angiography and ultrasonography are thought to be sufficiently effective methods of diagnosis of vessel aneurysms.
