Injuries to the azygous venous system

The Journal of Trauma

Abstract

Azygous venous system injuries are rare. Although not commonly classified as a thoracic great vessel, the azygous system manifests morbidity and mortality that is similar to that of other great vessel injuries. Over a 40 year period, data were retrospectively collected and charts reviewed from a vascular injury database. A total of 22 injuries to the azygous venous system were identified with 21 to the azygous vein and 1 to the hemiazygous vein. All were secondary to penetrating trauma, with 19 from gunshot wounds and 3 from stab wounds. Eight of 22 patients died for an overall mortality of 36%. All patients had associated injuries, with concomitant injury to the lung noted in all cases. Injuries to the azygous venous system have a significant associated lethality. As an azygous venous injury is not typically the indication for operation, anterior incisions are often employed, making exposure difficult. In the majority of injured patients, the azygous system injury was found after excluding injuries to the heart, lung, and great vessels. A key finding in detecting these injuries through an anterior incision is continued hemorrhage of dark blood from a posterior location in the thoracic cavity. The azygous venous system should b...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.
