Fat Embolism Due to Avascular Necrosis Leading to Acute Chest Syndrome in Sickle Cell Disease in a Youth: A Lethal Encounter.

ABSTRACT

Fat embolism syndrome (FES) is a rather uncommon presentation in sickle cell disease (SCD), most frequently happening in the context of long bone fractures following trauma. On the other hand, nontraumatic scenarios and nonorthopedic injuries have been documented to cause fat embolisms. This article describes the case of an 18-year-old male patient who had a known case of SCD (SS pattern). The patient complained of hip pain, and it was discovered that he had avascular necrosis of the right femoral head. The patient was started on opioid analgesics and started to respond to treatment; however, on the third day of admission, his condition deteriorated, oxygen saturation dropped, and the patient was shifted to the intensive care unit, where he was diagnosed with FES due to avascular necrosis. The patient's condition further deteriorated; he could not be saved and succumbed to death within one day. Very rarely has SCD with FES been reported in the literature.
