Arterial cannulation can hasten the onset of symmetrical peripheral gangrene.

Symmetrical peripheral gangrene (SPG) is a devastating complication seen in critical care settings due to several contributory factors like low perfusion, high dose of vasopressors, disseminated intravascular coagulation, etc. Arterial cannulation is commonly done in critical patients for monitoring. We report a case of patient who developed early features of SPG which recovered in one hand, although it progressed in the hand which had the arterial cannula.
