Deep vein thrombosis of upper extremities due to reactive thrombocytosis in septic patients.

Deep venous thrombosis (DVT) is not an uncommon condition in the intensive care unit (ICU), and having high morbidity and mortality. Upper limb DVT also is increasingly being recognized as a clinical entity. The presence of the indwelling catheter in neck veins is a risk for developing venous thrombus, which may be further aggravated by presence of thrombocytosis. In ICU patients with sepsis, reactive thrombocytosis has been found during the recovery phase. Here, we are presenting two cases, having thrombocytosis and central venous catheter who developed upper limb DVT.
