Pathogenesis
Septic emboli most often originate from extrapulmonary locations which have been infected for a period of time. For example, a person's intravenous access site, which is used to insert intravenous drugs, may become infected. When present in great number, septic emboli can coalesce and mimick a lobar or bronchopnuemonia. The infected site, combined with various coagulants that may be generated by the bacteria or the body, may then break off and enter the circulatory system, potentially causing a clot.
