Recovery of Symmetrical Peripheral Gangrene of Limbs in a Patient After Performing Hemoadsorption in Septic Shock.

Abstract

We report a 42-year-old patient who had Hodgkin lymphoma and developed bilateral symmetrical peripheral gangrene (SPG) in the feet and hands, which occurred during septic shock after autologous hematopoietic stem-cell transplantation. SPG is a rare but severe complication of disseminated intravascular coagulation (DIC) and is frequently associated with sepsis. The pathophysiology of SPG includes DIC-mediated intravascular thrombosis and thrombotic occlusion of microcirculation, resulting in low blood flow. Sepsis-induced hypotension has been suspected as one of the other causes of SPG, and it is thought to be aggravated by vasopressor treatments given for hypotension. Our patient first experienced coldness, paleness, and cyanosis in his body's acral parts, and then SPG later developed in both his feet and hands. Septic shock management was performed with cytokine hemoadsorption, broad-spectrum antibiotics, and massive fluid replacement rapidly. The patient fully recovered without the need for amputation. Hemoadsorption is an extracorporeal cytokine-adsorption method for removing excess cytokines. Prompt management of septic shock and early monitoring of peripheral ischemia are essential to avoid SPG.
