Do results justify an aggressive strategy targeting the pedal arteries for limb salvage?

We initiated a strategy to bypass all of the significant popliteal and tibial disease in the setting of limb-threatening ischemia beginning in September 1986. Of 194 infrapopliteal bypasses performed for limb salvage during the ensuing 6 years, 111 (57%) autogenous vein bypasses were performed to the pedal vessels at or distal to the ankle. By life table analysis, primary graft patency at 60 months for pedal bypasses was 57%, with salvage of failed grafts resulting in secondary patency of 61%. Limb salvage was 64% at 60 months. Of 33 graft thromboses, 24 (73%) resulted in eventual limb loss. Five limbs were amputated due to wound complications or progressive forefoot sepsis despite patent pedal grafts. More bypasses were performed to the dorsalis pedis than the posterior tibial at the ankle (78 vs 33), but patency and limb salvage were similar. Bypasses to the pedal arteries resulted in superior limb salvage compared with peroneal bypass when forefoot tissue necrosis was present (63 vs 33% at 36 months, P = 0.048). Pedal grafts had comparable overall patency (57 vs 64%) and limb salvage (64 vs 75%) to more proximal tibial bypasses. Pedal bypass provides acceptable long-term outcomes for both patency and limb salvage. When foref...Continue Reading

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.

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.

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.

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.


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.

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.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
