Creation of 6-10mm Diameter Transjugular Intrahepatic Portosystemic Shunts Using a Novel TIPS Stent Graft in a Swine Model.

Purpose: To assess the delivery, function, and patency of a new expanded polytetrafluoroethylene encapsulated TIPS stent- graft ("Liverty") in an animal model.

Materials And Methods: TIPS were created in 2 successive groups: 14 single & 10 overlapping devices, in swine weighing 52-64kg. Explants occurred at 30 (n=10) and 60 (n=14) days.

Integrative multi-omics characterization of hepatocellular carcinoma in Hispanic patients.

Background: The incidence and mortality rates of hepatocellular carcinoma among Hispanic individuals in the United States are much higher than in non-Hispanic White people. We conducted multi-omics analyses to elucidate molecular alterations in hepatocellular carcinoma among Hispanic patients.

Methods: Paired tumor and adjacent nontumor samples were collected from 31 Hispanic hepatocellular carcinomas in South Texas for genomic, transcriptomic, proteomic, and metabolomic profiling.

Ex Vivo Porcine Model for Ureteral Stent Placement Training.

Realistic simulation models for interventional radiology procedures are limited, including for placement of double-J ureteral stents (DJSs). Using a porcine kidney and empty saline bag (bladder), an ex vivo model aiming to improve operators' knowledge and confidence in performing a DJS procedure was developed. Six faculty (J.

Biliary Leaks: Multidisciplinary Approach to Diagnosis and Treatment.

Bile leaks arise from various causes such as trauma, complications after hepatobiliary surgery, and intrahepatic malignancies or their associated liver-directed treatments. Bile leaks can result in significant morbidity and mortality. Delayed diagnosis is not uncommon due to nonspecific manifestations; therefore, a high clinical suspicion is needed.

Changes in Microwave Ablation Zone Dimensions after Transarterial Embolization in an Ex Vivo Human Kidney Perfusion Model.

Purpose: To utilize a novel ex vivo perfused human renal model and quantify microwave ablation (MWA) size differences in renal tissue when combining MWA with transarterial embolization (TAE).

Materials And Methods: Human kidneys (n = 5) declined for transplantation were obtained and connected to a fluoroscopy-compatible ex vivo perfusion system. Two ablations-1 standard MWA and 1 TAE-MWA-were performed in each kidney for 2 minutes at 100 W using a MWA system (Solero Angiodynamics).
