Revascularization Surgery: Its Efficacy for Limb Salvage in Diabetic Foot

Annals of Plastic Surgery
Tzu-Yen Chang, Shyh-Jou Shieh

Abstract

The estimated prevalence of diabetes is 9.78% in Taiwan. The lifetime risk for patients with diabetes to have foot ulcers might be as high as 25%. About 15% of these patients require major limb amputation because of ischemia and infection. Peripheral artery disease is still a major problem involved in diabetic foot disease and the cause for major amputation despite an increase in the prevalence of revascularization surgery and new revascularization techniques over the past 20 years. We investigated the major limb amputation rates in patients with diabetic foot and critical limb ischemia who had undergone revascularization surgery in our hospital. The records of 42 patients who had undergone revascularization surgery for diabetic foot were retrospectively reviewed. Nineteen patients (45%) required major limb amputation despite revascularization. The affected limbs of only 15 patients (36%) were salvaged. Four patients died soon after surgery because of comorbidities, and another 4 were lost to follow-up. Two patients died from procedure-related sepsis, and overall perioperative mortality was 4.8%. Ten predictive risk factors (duration of diabetes, history of smoking, coronary artery disease, congestive heart failure, cerebral va...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.
