Radiographic evaluation of patency of interposition mesocaval shunts
Abstract:
The technique of side-to-side mesocaval anastomosis with the interposition of a prosthetic graft was described in 1970. We report the result of venographic evaluation of patency of this type of shunt in our patients. Demonstration of an unoccluded graft; resistance to retrograde injection of dye against the blood stream into the superior mesenteric vein; rapid clearing of dye from superior mesenteric vein following injection and "lamellar flow defect" in the vena cava above the site of anastomosis during vena cavogram, were considered criteria of patency of the interposition mesocaval shunt.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
