Endovascular transsplenic recanalization with angioplasty and stenting of an occluded main portal vein in an adult liver transplant recipient

Radiology Case Reports, 2020
Endovascular transshepatic access has limitations that can be exacerbated in the posttransplantation setting. Although several techniques are available for portal venous system catheterization, the transsplenic approach offers a direct pathway for ...

All about portal vein: a pictorial display to anatomy, variants and physiopathology

Insights into Imaging, 2019
The portal vein (PV) is the main vessel of the portal venous system (PVS), which drains the blood from the gastrointestinal tract, gallbladder, pancreas, and spleen to the liver.

Effects of a Web-Based Patient Portal on Patient Satisfaction and Missed Appointment Rates: Survey Study

Journal of Medical Internet Research, 2020
BackgroundAlthough electronic medical record (EMR)-tethered patient portals are common in other countries, they are still emerging in Canada. ObjectiveWe aimed to report user satisfaction and the effects of a patient portal on medical ...

Transhepatic ultrasound guided embolization as a successful novel technique in treatment of pediatric complex intrahepatic arterioportal fistula: a case report and review of the literature

Journal of Medical Case Reports, 2023
Introduction Intrahepatic vascular shunts “IHVS” are abnormal communications between intra-hepatic vasculature involving the arterial, portal, or hepatic venous system.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Haematological splenomegaly does not directly relate to portal hypertension: From a clinical study to surgical choice

Archives of Clinical and Experimental Surgery, 2017
Background: Splenomegaly induces an increased inflow into the portal venous system; however, in the absence of pathology of the liver and of a portal vein system, secondary portal hypertension is unusual.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Thrombosis of the Portal Venous System in Cirrhotic vs. Non-Cirrhotic Patients

Annals of Hepatology, 2018
Introduction and aim. Thrombosis is a vascular disorder of the liver often associated with significant morbidity and mortality. Cirrhosis is a predisposing factor for portal venous system thrombosis.
