The Hemashield Woven prosthesis in the thoracic aorta: a prospective computer tomography follow-up study

Abstract

Dacron prostheses in humans have been documented to present long-term fiber alterations, that may account for late graft dilatation. Late dilatation has been documented mainly in knitted prostheses, implanted in the abdominal and thoracic aorta. Dilatation of the collagen-impregnated Hemashield Woven prosthesis has not been studied prospectively in the thoracic aorta. Twenty patients were prospectively included. The intraoperative performance of the graft and mid-term clinical behaviour were studied. The graft distensibility was evaluated by postoperative, 1 and 3 yr computed tomographic diameter follow-up. There were no hospital deaths. Two graft-unrelated deaths occurred at 3 yr. The graft performance was excellent or good for most aspects. No significant changes in CT diameter occurred throughout the 3 yr follow-up. The collagen-impregnated Hemashield Woven prosthesis is considered safe in replacements of the thoracic aorta. Future evaluation should focus on the very long-term behaviour in young adults.

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.
