Lower-extremity saphenous vein transposition arteriovenous fistula: an alternative for hemodialysis access in AIDS patients

Abstract

Arteriovenous access for long-term hemodialysis in patients with the acquired immunodeficiency syndrome (AIDS) represents a special challenge. Many of these patients are chronic intravenous drug abusers and do not have patent superficial upper-extremity veins available for conventional arteriovenous fistulas. This group of patients is also particularly prone to infections, which contraindicates the use of prosthetic grafts. Over a period of 13 months, five lower-extremity saphenous vein transposition arteriovenous fistulas (SVTAFs) were performed. Four patients had a diagnosis of AIDS at the time of operation; all of these were intravenous drug abusers. Three patients were male, two were female, and their age ranged from 34 to 66 years (mean, 48). Three patients had a SVTAF as their first hemodialysis access, and in two it was performed after multiple failed upper-extremity accesses. Four fistulas remain patent to date, after a mean follow-up of 11 months (range, 4 weeks to 16 months). One fistula thrombosed 4 weeks postoperatively, due to a hematoma that occurred after premature venipuncture for dialysis. There were no other major complications. We conclude that SVTAF is a suitable alternative to the limited hemodialysis venou...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.
