Chronic critical limb ischemia: what is the benefit of radiological intervention? Indications and results

Journal belge de radiologie

Abstract

Indications of interventional radiological procedures in patients with chronic critical limb ischemia are not clearly defined. PTA of limb arteries is used only in 3 of 4% of patients, although 20 to 40% might be candidates for a proximal intervention in the iliac arteries. Following PTA of intrapopliteal arteries, limb salvage varies from 56 to 82% and arterial patency rate from 34 to 100% after 1 to 2 years follow-up in non controlled case series studies. Arterial local thrombolysis shows better results than surgery in subgroups of patients in a few studies. Pulse spray technique does not show better clinical results than conventional infusion of the plasminogen activator. Overall, radiological interventions give similar results compared with surgery, concerning limb salvage rate, length of hospital stay, morbidity and mortality, but significantly more patients are discharged home versus a nursing institution after radiological treatment than after surgery. Radiological techniques seem to be cost effective compared to surgery. Amputation should be carried out only after all revascularization possibilities have been ruled out at a multidisciplinary vascular center.

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.
