* Usually due to [[peripheral arterial disease]], but can also be caused by [[acute limb ischemia]].
* Presents with dry, shrunken tissue, usually ranging from dark red to completely black, often with a clear line of demarcation between healthy and necrotic tissue. 
*Typically not painful.

==Differential Diagnosis==
{{Foot infection}}

==Evaluation==
* History and physical examination are usually sufficient to make the diagnosis. 
*If [[acute limb ischemia]] is suspected, consider a CTA of the affected limb and a vascular surgery consultation.
*If has any areas consistent with [[wet gangrene]] or surrounding [[SSTI]], treat as for those entities

==Management==
*Infection rarely present
**<8% of cases convert to wet gangrene <ref> Latz CA et.al. Rates of conversion from dry to wet gangrene following lower extremity revascularization. Ann Vasc Surg. 2022;83:20–25. https://www.sciencedirect.com/science/article/pii/S0890509622000115. doi: 10.1016/j.avsg.2022.01.005. </ref>
*Keep area clean and dry to prevent infection; consider debridement
*Will usually auto-amputate in <6mo
*Refer to vascular surgery in case fails to auto-amputate; may benefit from revascularization therapy to prevent further tissue death. 
**Diabetes or immunocompromise may warrant lower threshold for consultation <ref> Rodrigues J, Mitt N. Diabetic Foot and Gangrene. Gangrene - Current Concepts and Management Options. Published online August 29, 2011. doi:https://doi.org/10.5772/23994 </ref>
*If [[acute limb ischemia]] is present, embolectomy or surgical bypass may be required to restore flow.

==Disposition==
*Outpatient, if [[acute limb ischemia]] is NOT a concern
