Delirium Superimposed on Dementia, in an Elderly Female Patient with Venous Thrombosis of the Leg

This is a challenging case of an elderly female patient, 86 years old that has been diagnosed with delirium superimposed on depression (DSD). This frustrated patient developed DSD in parallel with venous thrombosis (VT) of her right leg. Venous thrombosis was initially superficial, affecting the Great Saphenous Vein (GSV), that later progressed into Deep Venous Thrombosis (DVT), which was confirmed by radiology (Doppler study) and laboratory investigations (D-dimer level assessment).
