Here we reported a case of compartment syndrome in the upper limb following an adder bite in the thenar eminence. Elevated compartment pressure was documented and immediate surgical fasciotomy was practiced. The patient achieved complete recovery with a good functional result. We discussed the controversies on fasciotomy and non-invasive measures in such a situation, and recommended intracompartmental pressure monitoring during the management of compartment syndrome following adder bites.展开更多
