Pulmonary Fat Embolism and Coronary Amyloidosis

Abstract

Patient: Male, 72Final Diagnosis: Fat lung embolismSymptoms: DyspneaMedication: —Clinical Procedure: —Specialty: Orthpedics and TraumatologyObjective:Diagnostic/therapeutic accidentsBackground:Fat embolism syndrome is a well-known complication in orthopedic and trauma surgery, caused by a massive release of fat into the circulation that can lead to cardiopulmonary insufficiency and multiorgan failure.Case Report:We present the case of a 72-year-old man with osteoarthritis who underwent an elective right cementless total hip arthroplasty. Two hours after surgery, the patient lost consciousness and was found hypotensive and with reduced oxygen saturation, with a severe right heart dilatation at echocardiographic evaluation. Death occurred after cardiopulmonary resuscitation attempts. Post-mortem microscopic examination revealed that the final cause of death was pulmonary fat embolism associated with coronary amyloidosis and atherosclerosis.Conclusions:This case called our attention on the sudden onset of fat embolism syndrome after arthroplasty and the insidious nature of amyloidosis infiltrative disease. The autopsy findings substantially aided understanding the immediate cause of death.

Clinical Characteristics of Six Cases of Tracheobronchopathia Osteochondroplastica

“…e pathogenesis of TO is still unclear. ere are several possible reasons, including congenital tracheobronchial dysplasia, long-term physical, chemical, or mechanical stimulation (fumes and irritating gases), chronic inflammation of tracheobronchial mucosa [6], metabolic disorders (endocrine hormone level or abnormal calcium and phosphorus metabolism), amyloidosis [11] and degeneration, and selective IgA deficiency [12]. e possible cause may also be the result of interaction between several reasons.…”

Risk factors for acute pulmonary embolism in patients with off-pump coronary artery bypass grafting: implications for nursing

“… 26 , 27 In elderly people aged older than 70 years, the physiological reserves of various organs are reduced, such as decreased heart, liver, and lung function. 28 Elderly people are prone to disturbance of the cardiovascular system. With development of society and improvement of people’s living standards, an increasing amount of elderly patients are undergoing coronary artery bypass surgery.…”
