Popliteal Artery Rupture During Total Knee Replacement in a Patient With Monckebem's Sclerosis Case Report

摘要

Medial calcification, or calcinosis, was first described by Monckeberg in 190.3, and is known as Monckeberg's arteriosclerosis. It commonly affects midsize, muscular arteries such as the femoral, tibial, radial, coronary, cerebral, and visceral arteries. It is mainly found in the arteries of the extremities in middle-aged or elderly individuals.The pathophysiology of Monckeberg's arteriosclerosis is unclear, but it can be induced in animal models by injecting adrenaline, nicotine, parathyroid hormone, and vitamin D.In addition, lumbar sympathectomy has been shown to promote Monckeberg's arteriosclerosis of the lower extremities in humans.5 Automatic dysfunction from diabetic neuropathy is believed to be responsible for Monckeberg's arteriosclerosis in young and middle-aged patients with diabetes.The medial calcification in diabetes often is associated with atherosclerotic and throm-botic lesions. Unlike atherosclerosis, Monckeberg's arteriosclerosis is a benign condition, does not cause vascular thrombosis, and is of little clinical significance.
