Academic career

In his doctoral thesis under Dr. Martin Staritz at Medical Clinic 1 at the University of Mainz, he could demonstrate in the late 80s that the recently introduced PW duplex sonography can yield valid and reproducible measurements of blood flow in the portal vein. The finding for the first time opened up a path for non-invasive assessment of portal hemodynamics. Non-invasive techniques could be used to administer physiological stimuli and medication, as well as to differentiate and quantify portal hypertension.

Following his medical internship, he worked from 1992 in the “portal hypertension” working group under Prof. Dr. Tilman Sauerbach at Medical Clinic 1 of Bonn University. Focus area of the working group was portal hemodynamics and treating complications of portal hypertension.

Dr. Schiedermaier used duplex sonography to investigate acute (somatostatin analogs) as well as chronic (ursodeoxycholic acid) pharmacological effects on portal hemodynamics and described for the first time the circadian rhythm of hemodynamics and the dependency of portal pressure and flow on portal resistance. He established portal duplex sonography as an important clinical method to assess the function of the transjugular intrahepatic portosystemic shunt (TIPS), which his working group could demonstrate as an effective means to treat hepatorenal syndrome. He obtained authorization to teach (venia legendi) at the medical faculty of Bonn University in 2004 and taught there until 2016.

Liver cirrhosis and related complications are a special medical problem in Pakistan. He has conducted a continuous medical education program in the country since 2004. His lectures, presentations, and workshops aim to train doctors in methods that are not established in Pakistan to date: in diagnostics, using portal duplex sonography and measurement of venous occlusion pressure to diagnose and characterize portal hypertension and contrast-enhanced sonography to differentiate focal liver lesions; in therapy, using radiofrequency ablation of hepatocellular carcinoma to treat liver cirrhosis complications, endoscopic therapy of varices as well as drug therapy of hepatorenal syndrome with terlipressin.

He has been a member of the medical faculty of the University of Saarland since 2016 and works closely with Prof. Dr. Frank Lammert and Medical Clinic II. Another focus area is the non-invasive sonographic characterization of chronic liver disorders. For this purpose, shear-wave elastography was validated. The dependence of the method on physiological stimuli and its calibration for various liver disorders are topics of doctoral theses which he currently supervises.
