[Acute ischemia of the extremities. As critical as a myocardial infarct].

Acute limb ischemia is a vascular-surgical emergency requiring immediate referral to a hospital provided with all the necessary therapeutic facilities. Essential initial measures are protection of the limb against continued cooling, management of pain, and bolus administration of heparin. For the physician providing further care, not only an accurate history, but, ideally, also the results of earlier investigations such as ECG, abdominal US or Doppler studies, provide useful information. In patients who have not undergone prior surgery vascular-surgical management, that is, embolectomy with a balloon catheter, is the treatment of choice. Furthermore, the patient requires continuing care after discharge; here, wound management and the supervision of anticoagulation measures that might be needed are important tasks for the general practitioner.
