PF4 and Thrombocytopenia: Previous studies demonstrated that VITT could manifest with fever, myalgia, headache, fatigue, chills, nausea, epigastric discomfort, headache, reduced consciousness, back pain, stroke symptoms, hemiparesis, dizziness, noted gum bleeding, decreased oral intake, and anorexia.5., 7., 11., 15., 16. The typical pattern of VITT, thrombocytopenia, low fibrinogen levels, very high D‐dimer, and high titers of anti‐heparin–PF4 antibodies were present in our patient, together with the sonographically confirmed thrombosis in the splenic vein.
