Septic pulmonary embolism: Is it an underestimated diagnosis?
Blog Article
Background: Non-thrombotic pulmonary embolism, an uncommon entity, is defined as the Vests embolization of tissues, microorganisms, air, or foreign material.One subset in this non-thrombotic category is septic pulmonary embolism (SPE) that refers to embolism of microorganisms with or without a thrombotic mantle into the pulmonary vasculature.This condition is often recognized on the basis of imaging with a clinical correlation.Unfortunately, data regarding the pathological features are meager.
This has prompted to review such cases at autopsy.Aims: To study the pathological features of SPE at autopsy.Materials and Methods: Ten-year (2012 to 2021) autopsy records of the hospital were retrospectively reviewed.The diagnosis was based on the identification of acute necrotizing pulmonary arteritis with peri-bronchoarterial consolidation.
These cases were analyzed with reference to the demographics, clinical characteristics, and pulmonary/extrapulmonary findings at autopsy.Statistical Analysis: Nil.Results: According to the inclusion criterion, 19 cases demonstrated the presence of SPE.There were 11 men and 8 women with a mean age of 32.
1 years.The major source of infection included infection arising from skin and musculo-skeletal system (11 patients, 59.7%).The common clinical presentation included fever, dyspnea, chest pain, hemoptysis, and altered sensorium.
The cause of death was mainly due to septicemia and/or confluent lung consolidations.A large number of bacterial colonies were seen in all; Candida species were also identified in two cases.Other lung findings included diffuse alveolar damage, fresh arterial thrombosis, infarction, arterial pseudo-aneurysms, abscess formation, and pyogenic Dryer Element Clip pleuritis.Conclusion: Presence of an extrapulmonary infection with persistent fever, bacteremia, and pulmonary complaints should raise suspicion for this entity, particularly in resource-poor settings, to prevent grave pulmonary complications.
