[Acute and critical ischemia of the lower limb].
Acute limb arterial occlusion has great clinical significance due to its high mortality and complication rates. Its diagnosis is easy; however staging after long-term occlusions can be very difficult with lack of exact criteria. It is crucial, since reversible stage should undergo revascularization, while with irreversible stage only amputation is curative. Due to occlusion, long-term ischemia occurs, resulting in injury of the muscle fibers and endothelial cells. In case of revascularization the reperfusion causes more damage, than ischemia alone locally and initiates a remote organ injury. The aim of the review is to summarize the knowledge and fact and focus on some exact methods or parameters which can determine the degree of injury. One of these methods is a new approach which is the use of enzyme-histochemical reactions, and could give rapid, precise results even preoperatively regarding tissue viability. Routine clinical application of it is predictable after proper standardization.
