Symptom narrative

I am NOT certain of the exact brand of influenza vaccine received - this was not given at my clinic. 12 days after receiving flu vaccine, she had an episode of LOC (described by the ER as syncopal episode with shaking, eyes rolled back) immediately after reporting feeling unwell. In the ER, d-dimer was elevated with normal troponin and this prompted a CT angio to eval pulmonary embolism which was normal. I am submitting this case because it is the second patient of mine this week to have an elevated d-dimer in the ER and undergo an eval for PE and I have never had a pediatric patient with these labs/evaluations before. EKG showed a left axis and nonspecific ST abnormalities and she was referred to cardiology.
