Answer

The most common organism reported in mastitis is Staphylococcus aureus. The organism usually comes from the breastfeeding infant's mouth or throat.

Thrombosis may occur. Numerous factors cause pregnant and postpartum women to be more susceptible to thrombosis. Pregnancy is known to induce a hypercoagulable state secondary to increased levels of clotting factors. Also, venous stasis occurs in the pelvic veins during pregnancy.

Although relatively rare, septic pelvic thrombosis is occasionally observed in the postpartum patient, who might have fever.
