Transjugular intrahepatic portosystemic shunt (TIPS) is a difficult procedure to perform and accessing the portal vein is a very challenging step. There are three broad categories of image guided TIPS creation techniques. Each technique has its advantages and disadvantages. TIPS procedure carries some risk of complications regardless of the guidance technique employed. The technology for TIPS h...
PURPOSE The majority of cirrhotic patients who underwent transjugular intrahepatic portosystemic shunt (TIPS) experienced the first post-TIPS hepatic encephalopathy (HE) episode within the first three months after TIPS insertion. However, so far, little is known about the exact neuro-pathophysiological mechanism of TIPS's effects on brain function. We aimed to investigate the dynamics of brain ...
The optical transmission and reflection in between two metalized optical fiber tips is studied in the optical near-field and far-field domains. In addition to aluminum-coated tips for near-field scanning optical microscopy (NSOM), specifically developed gold-coated fiber tips cut by focused ion beam are investigated. Transverse transmission maps of subwavelength width clearly indicate optical n...
