Portal vein tumor thrombus: demonstration by computed tomographic ateriography

Portal vein thrombosis (PVT) is a frequent complication in patients with portal hypertension resulting from end-stage liver disease. In certain instances, PVT may be a contraindication for liver transplantation. We have developed a novel approach for managing PVT cases involving complete occlusion of the main trunk of the portal...

Source: Kim, D., et. al. Combined Near-infrared Fluorescent Imaging and Micro-computed Tomography for Directly Visualizing Cerebral Thromboemboli. J. Vis. Exp. (2016)This video demonstrates visualization of cerebral thrombus in mice using micro-computed tomography (micro-CT) imaging. A cerebral thrombus mouse model is injected with fibrin-targeted gold nanoparticles acting as a contrasting agent. The mouse is placed on the bed of a micro-CT machine, and images are acquired from multiple angles.

This video describes a surgical procedure to deliver mammary tumor cells to the murine liver via portal vein injection. This model permits the investigation of late stages of liver...

The protocol describes a straightforward method of resectioning an intact mouse liver for metabolic studies through portal vein...

Portal vein injection of colorectal cancer (CRC) organoids generates stroma-rich liver metastasis. This mouse model of CRC hepatic metastasis represents a useful tool to study tumor-stroma interactions and develop novel stroma-directed therapeutics such as adeno-associated virus-mediated gene...

A surgical procedure was developed to deliver mammary tumor cells to the murine liver via portal vein injection. This model permits investigation of late stages of liver metastasis in a fully immune competent host, including tumor cell extravasation, seeding, survival, and metastatic outgrowth in the liver.
