A patient who has undergone selective embolization of an organ or tumor may develop a postembolization syndrome afterwards. This is ascribed to an inflammatory response to the tissue necrosis.
Features of the postembolization syndrome:
(1) fever
(2) localized pain
(3) nausea and vomiting
(4) malaise and fatigue
Symptoms usually subside in 4-5 days.
Patients can be managed conservatively with hydration, antibiotics, analgesics, antipyretics and antiemetics.
Differential diagnosis for exclusion:
(1) infection of the infarcted tissue
(2) ongoing hemorrhage
