Manipulating waves by distilling frequencies: a tunable shunt-enabled rainbow trap [PDF]

Smart Mater. Struct. 25, 085017 (2016), 2016
In this work, we propose and test a strategy for tunable, broadband wave attenuation in electromechanical waveguides with shunted piezoelectric inclusions. Our strategy is built upon the vast pre-existing literature on vibration attenuation and bandgap generation in structures featuring periodic arrays of piezo patches, but distinguishes itself for ...

FIGO guideline on liver disease and pregnancy

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract The number of women entering pregnancy with chronic liver disease is rising. Gestational liver disorders affect 3% of the pregnant population. Both can be associated with significant maternal and fetal morbidity and mortality. European guidance has recently been published to inform management.

Selective embolization of the splenic vein for shunt-preserving disconnection of the portal and systemic circulation: Report of two cases

Acta Radiologica Open, 2012
In carefully selected patients with portosystemic encephalopathy, it is possible to safely disconnect the portal and systemic circulation while preserving the shunt.

TIPS and HCC: friends or foes ? [PDF]

, 2016
Portal hypertension and hepatocellular carcinoma [HCC] are major complications of liver cirrhosis and may coexist in the same patient. Transjugular intrahepatic portosystemic shunt [TIPS] is an effective treatment for recurrent variceal bleeding

Intrahepatic portosystemic venous shunt. [PDF]

American Journal of Roentgenology, 1990
Among numerous variations of communications between the portal and systemic venous circulations, intrahepatic shunts between portal and systemic veins have seldom been described [1 , 2]. Recently we encountered an intrahepatic portosystemic venous shunt directly connecting the right portal vein to the inferior portion of the vena cava.

Portal vein hypoplasia in dogs [PDF]

, 2014
Portal vein hypoplasia (PVH) is a congenital disorder, in which microscopic intrahepatic shunts are present, causing blood to bypass the liver sinusoids.

Paraumbilical collateral veins on MRI as possible protection against portal venous thrombosis in candidates for liver transplantation [PDF]

, 2007
Background: We retrospectively evaluate the potential protective influence of patent paraumblical vein (PUV) collaterals against portal vein (PV) thrombosis and reduced PV diameter in candidates for orthotopic liver transplant (OLT) Methods: Dynamic 3D ...

Tunable elastic Parity-Time symmetric structure based on the shunted piezoelectric materials [PDF]

, 2018
We theoretically and numerically report on tunable elastic Parity-Time (PT) symmetric structure based on shunted piezoelectric units. We show that the elastic loss and gain can be archived in piezoelectric materials when they are shunted by external circuits containing positive and negative resistances.

Multiple Concomitant Precipitating Factors of Hepatic Encephalopathy Are Associated With a Poor Prognosis in Patients With Cirrhosis Admitted to Intensive Care Unit

United European Gastroenterology Journal, EarlyView.
ABSTRACT Introduction Management of hepatic encephalopathy relies on the identification and control of precipitating factors (PF). The prognostic value of a PF is unknown, which we aimed to explore. Patients and Methods Single‐center retrospective study of cirrhotic patients included in a prospective cohort admitted to an intensive care unit (ICU ...

Transportal Technetium-99m Labeled Macroaggregated Albumin Scintigraphy to Quantify Occult Intrahepatic Microvascular Portosystemic Shunting

Radiology Case Reports, 2021
Nodular regenerative hyperplasia (NRH) of the liver may lead to noncirrhotic portal hypertension with subsequent development of portosystemic shunts. While extrahepatic and macrovascular shunts are readily visualized with imaging or endoscopy, there is ...
