Upper Limb Phlegmasia Cerulea Dolens Secondary to Heparin-induced Thrombocytopenia Leading to Gangrene.

We present a case of a dialysis-dependent end-stage renal disease patient who originally presented with sepsis and later developed heparin-induced thrombocytopenia-related upper extremity deep venous thrombosis that rapidly progressed to phlegmasia. Argatroban, a direct thrombin inhibitor, was initiated without delay. Argatroban restored the venous patency completely but did not reverse his two gangrenous fingers. The patient finally underwent digital amputation. The management of this uncommon, but life-threatening, situation of upper limb phlegmasia cerulea dolens secondary to heparin-induced thrombocytopenia leading to gangrene is discussed in this case report.
