“…[4] Although Ludwig's angina often results as a complication of severe odontogenic infection, several other etiological and risk factors have also been implicated. These include diabetes mellitus,[45] HIV infection,[4] pregnancy,[6] puerperium,[7] alcoholism,[3] chronic malnutrition,[8] and low socioeconomic status. [9] The peculiarity of Ludwig's angina among odontogenic infections is its propensity for rapid spread, capable of leading to airway obstruction, carotid arterial rupture or sheath abscess, thrombophlebitis of the internal jugular vein, mediastinitis, empyema, necrotizing fasciitis, pericardial effusion, osteomyelitis, and septicemia.…”
