[Differential diagnosis of endangiitis and arteriosclerosis obliterans].

41 males at the age from 20 to 40 years with chronic obstruction of the arteries of the extremities were on the basis of anamnestic and clinical findings subdivided into the groups obliterating endangiitis (group I = 20 patients) and obliterating arteriosclerosis (group II = 11 patients). In 10 patients in this way no decision for one of the two diagnoses could be made (group III). By multidimensional variance and discriminance analysis of various clinico-chemical parameters the separation of the groups I and II could be proved. The efficiency was 93.6% in the discrimination with 10 characteristics. With the help of the calculated non-elementary, linear characteristics of discriminance the patients could be classified into the group III. 7 patients could be classified into the group II and 3 patients into the group I. Thus we succeeded in differing 23 patients with obliterating endangiitis from 18 patients who as arteriosclerotics belong to the metabolic syndrome.
