The purpose of the study was to compare the electrophysiological parameters (nerve conduction studies and quantitative electromyography [EMG]) between patients with chronic peripheral arterial disease (PAD) and normal control subjects. Forty patients with PAD and 30 control subjects (40 legs) were evaluated clinically and electrophysiologically using previously described methods. The amplitude of compound muscle action potentials (CMAPs) and the motor conduction velocities (MCVs) of peroneal and tibial nerve for most patients with PAD were within normal limits but compared with those of the controls, it was found that the peroneal and tibial MCVs as well as the amplitude of sural nerve were significantly decreased. The EMG testing of patients with PAD and controls of the anterior tibialis and the gastrocnemius muscle did not show evidence of denervation or myopathic abnormalities. However, the mean amplitude and duration of both muscles were significantly larger compared with the controls. Routine electrophysiological studies are not the appropriate (sensitive enough) tests for detecting peripheral nerve or muscle dysfunction associated with PAD.

Background: Aortoiliac disease (AID) is a variant of peripheral artery disease involving the infrarenal aorta and iliac arteries. Similar to other arterial diseases, aortoiliac disease obstructs blood flow through narrowed lumens or by embolization of plaques. AID, when symptomatic, may present with a triad of claudication, impotence, and absence of femoral pulses, a triad also referred as Leriche Syndrome (LS).

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.

Introduction: Patients with peripheral artery disease (PAD) can experience intermittent claudication, which limits walking capacity and the ability to undertake daily activities. While exercise therapy is an established way to improve walking capacity in people with PAD, it is not feasible in all patients. Neuromuscular electrical stimulation (NMES) provides a way to passively induce repeated muscle contractions and has been widely used as a therapy for chronic conditions that limit functional capacity.

: Peripheral artery disease (PAD) is a prevalent vascular condition characterized by arterial narrowing, which impairs blood flow and manifests as intermittent claudication, a pain or cramping sensation induced by physical activity or ambulation. Walking distance is a crucial clinical indicator of peripheral artery disease, and it correlates with the disease severity and risk of mortality. It reflects the severity of the disease, with reduced mobility indicating an increased risk of morbidity.

: Medial arterial calcification (MAC), a distinct form of vascular pathology frequently coexisting with peripheral arterial disease (PAD), poses unique challenges in limb salvage among patients with diabetes, chronic kidney disease, and end-stage renal disease. This study examines the incidence of MAC and its impact on limb salvage outcomes over a decade of experience at a tertiary limb salvage center. : A retrospective review of all complex lower extremity (LE) reconstructions using local flap (LF) or free tissue transfer (FTT), performed from July 2011 to September 2022, was conducted.
