Detection of Superior Vena Cava Obstruction on Dynamic 99mTc-DTPA Renal Transplant Scintigraphy

Detection of Superior Vena Cava Obstruction on Dynamic 99mTc-DTPA Renal Transplant Scintigraphy

We present an asymptomatic patient with a history of prolonged hemodialysis through a right internal jugular vein catheter who was diagnosed with superior vena cava (SVC) obstruction on 99mTechnetium-diethylenetriaminepentaacetic acid renal transplant scintigraphy. During the angiographic phase, an unusual vascular filling pattern was detected on the anterior view of the abdomen. Angioscintigra...

Benign obstruction of the superior vena cava.

Hunter' was the first to report a case of superior vena cava obstruction. Ehlrich2 et al. and McIntire and Sykes3 have extensively reviewed the world literature. Obstruction of the superior vena cava due to primary endothoracic malignant tumours or aneurysm is not uncommon, accounting for 94 per cent. of our cases, but benign lesions causing obstruction of this vessel are rare Oschner and Dixon...

CT findings in superior vena cava obstruction.

T HE CLINICAL manifestations of SVCS were first described by Hunter in 1757, secondary to a syphilitic aneurysm of the ascending aorta.’ SVCS usually has an insidious presentation and eventually leads to a collection of signs and symptoms that together are diagnostic of the disorder. Obstruction of the SVC may result from external compression or intrinsic thrombotic disorders, and leads to prox...

Application of 99mTc-DTPA Radiotracer in Persian Cat’s Renal Scintigraphy

Purpose: To evaluate the suitability of Tc-DTPA as a radiotracer in Persian cat's renal scintigraphy. Methods: twelve adult healthy Persian cats were selected. For scintigraphy, the animals were anesthetized and TC-DTPA was injected via the femoral vein as a bolus at a dose of 1.5 mCi. Immediately after intravenous injection of radiotracer, scintigraphic operation was conducted on the renal org...
