There may be associated thrombosis, either venous (deep venous thrombosis, pulmonary embolism, venous limb gangrene) or arterial (cold digits or extremity). Skin necrosis at the site of heparin injections may also be seen. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/11/10 UR - accessmedicine.mhmedical.com/content.aspx?aid=1185662813 ER -
