Non-concave edema of the limb

Non-concave edema: Refers to pressing the edema part of the limb with fingers, and those who do not show depression immediately are non-concave edema, which is mainly seen in myxedema caused by hypothyroidism. With the development of vascular surgery, the treatment of acute arterial embolism has made promising progress, but the mortality and amputation rate of the affected limbs are still quite high. The main cause of this result is ischemic rhabdomyolysis and the resulting red muscle Protein, ion disorders, oxygen free radicals, etc. cause the metabolic syndrome (myonephropathic-metabolic syndrome, MMS), namely myopathy nephropathy metabolic syndrome. In the past, insufficient attention has been paid to this metabolic change, so the prognosis of patients is poor. Recent literature statistics show that the incidence of MMS after acute arterial obstruction is 7% to 37.5%, and the true incidence is still unknown. Anyone with the etiology of MMS should consider the possibility of MMS. Early prominent manifestations are muscle contraction, joint stiffness, and non-concave edema of the affected limb. Patients can develop psychiatric symptoms due to the effects of pain, metabolic disorders, and azotemia. Revascularization and reperfusion periods are characterized by non-concave edema, fuchsia urine, oliguria or anuria, and impaired cardiac function.
