Lemierre’s syndrome as a rare cause of septic pulmonary embolism (case report)
Abstract
Objectives. The purpose of this work is to provide a clinical case study of Lemierre’s syndrome (LS) in order to raise awareness amongst doctors of various medical specialties regarding this rare cause of septic pulmonary embolism (SPE).Materials and methods. The patient in clinical case is a 25-year-old female who was hospitalized due to SPE, which had been complicated by respiratory distress, pneumothorax and septic shock. The initial source of embolus lung damage was the septic thrombosis of both the internal and external jugular veins. This thrombosis occurred against the backdrop of a carbuncle of the lower lip, an inflammatory infiltrate at the bottom of the mouth, an abscess in the soft tissue of the chin and neck cellulitis, which correspond to the diagnostic criteria for Lemierre Syndrome.Results. The literature data of the epidemiology, etiology, pathogenic mechanisms of the venous thrombosis, embolic and septic complications among patients with LS are presented. The article discusses the clinical features and course of the disease, as well as key aspects of diagnosis, including current diagnostic criteria, with regard to the typical and atypical variants of LS. The principles of antibiotic therapy and the possibility of anticoagulation therapy in cases of septic pulmonary emboli associated with head and neck vein thrombosis are also considered.Conclusion. LS is a rare, but clinically significant condition characterized by the development of septic thrombosis in the internal jugular vein in response to acute suppurative inflammation of the head and neck. In typical cases, the causative organism is Fusobacterium necrophorum, or other anaerobic bacteria. This pathological condition is often accompanied by multiple other septic complications, with the most significant being the development of septic pulmonary embolism. Clinical observation indicates the necessity for including LS in the differential diagnosis among causes of the septic pulmonary embolism, and for adopting a multidisciplinary approach in the treatment of these patients in a specialized multifield hospital. Identification and diagnosis of Lemierre Syndrome can be challenging due to its low incidence and variable clinical presentation. Although the condition is not widely recognized among physicians, an understanding of the basic principles of its diagnosis and management can significantly improve treatment outcomes and patients prognosis.
