5Fr DL BARD PICC was inserted on November 2nd for Home Health ABX for UTI. Treatment was done on November 19. PICC was removed by Home Infusing Nurse. Next day the arm started swelling and painful, getting worse over the weekend. Patient went to see primary MD and doppler US was done. Extensive DVT was confirmed from basilic, part of cephalic, axillary, subclavian, and jugular veins. Patient stated that the arm was perfectly fine before PICC removal. Anybody has any idea about this situation? Thank you in advance.
