Abstract

Left renal vein (LRV) has been considered as the most suitable vein for proximal splenorenal shunt (PSRS), a commonly performed shunt for non-cirrhotic portal hypertension. Anatomical anomalies in LRV that can pose technical difficulty during shunt procedure are reported in 10% cases. We report a rare anomaly of LRV which precluded performance of standard end-to-side proximal splenorenal shunt and describe its management by performing an interposition end-to-end proximal splenorenal shunt. A 50-year-old female presented with recurrent episodes of upper gastrointestinal bleed for five years. She was pale and had a massive splenomegaly. There were no signs of encephalopathy. Upper gastrointestinal (UGI) endoscopy revealed three columns of grade 3 esophageal varices, large fundal varices and mild portal hypertensive gastropathy. Duplex ultrasound and contrast-enhanced computed tomography (CECT) of the abdomen was suggestive of non-cirrhotic portal fibrosis. She underwent an interposition end-to-end proximal splenorenal shunt with inferior branch of left renal vein. She developed partial shunt thrombosis at follow-up of 18 months and underwent balloon angioplasty and metallic stenting of shunt. She is doing well at 24 months follow...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
