RESUMO
When a melito-diabetic patient presents trophic infected injury on the limb, it is essential an evaluation of the circulatory conditions for therapeutic procedures orientation. In some circumstances, although arterial pulsation is absent, there is no ischemia of tissues. In these cases, the maintenance treatment, with eventual resection of the necrosed and infected tissues may be adopted. Evolution of 70 diabetic patients with trophic injuries on extremities were submitted to a maintenance treatment. Age of patients varied from 28 to 88 years, with an average of 56.8. The most occurrence was verified in women, with 42 cases. Diabetes non-dependent on insulin (type II) was observed in 64 patients (91.5%), being the remaining 6 patients of type I. Diabetic retinopathy was observed in 14 (20%) of the patients, neuropathy in 22 (31%) and nephropathy in 8 patients (11.4%). All the patients presented arterial pulsation until the popliteal region. They were divided in 2 groups, considering trunk arteries of legs: Group I, pervial legs arteries, composed by 48 patients; Group II, occluded legs arteries, with 22 patients. In what refers to the anatomic local of the injuries, patients were classified in three groups: Group A, formed by 32 patients (45.7%), presenting injuries in one or two toes only, without affecting the metatarsic region; Group B, formed by 16 patients (22.9%), trophic injuries affecting the metatarsic region and Group C, formed by 22 patients (31.4%), injuries affecting the calcaneous region. Injuries in both of the groups were caused by mechanical traumatism. Duration of the injury in the inferior member varied from 7 to 48 days, resulting in a 12 days average.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors report the results obtained from peripheral nerve crushing in the treatment of ischemic rest pain and/or trophic lesions of toes and feet. They studied retrospectively 102 patients who were submitted to peripheral nerve crushing at the "Hospital das Clínicas da Universidade de São Paulo" during a sixteen-year period, from March 1971 to April 1987. These patients had no other choice, either clinical or surgical. The results were evaluated under three aspects: elimination of pain, evolution of trophic lesions and postoperative complications. The follow-up period varied from 1 month to 6 years (mean of 18 months). The results showed immediate elimination of pain in 94% of the patients. The remaining 6% were reoperated on within 24 to 48 hours, due to technical failure in identifying some of the nerves during the first operation. Regarding the trophic lesions, in 71% of the patients the results were good and the remaining underwent amputation at leg or thigh. The worst results were obtained in patients with necrotic lesions (p < 0.05). Three patients presented surgical wound dehiscence. The authors conclude that peripheral nerve crushing constitutes a valid alternative for a select group of patients with uncontrollable ischemic rest pain in the feet.

Twenty patients with peripheral arteritis due to an infectious disease were studied with the purpose to detect the etiological agent in the vessels belonging to ischemic areas; to establish the relationship between the onset and evolution of the ischemic lesions and the infectious disease; and to verify the appropriateness of the treatment with anticoagulants. Ten patients had meningococal disease with positive blood culture for Neisseria meningitidis. The meningococci were found in vessel walls of ischemic areas. The cutaneous lesions had sudden onset and a rapid evolution. Five patients had pneumonia or gastroenteritis. No microorganisms were detected in the vessel walls of the ischemic areas. The cutaneous necrotic lesions appeared from two to six days after the infectious disease was diagnosed. Therefore, heparinization was considered appropriate to block the extension of the disseminated intravascular coagulation secondary to the vasculitis. Three patients had, probably, post-streptococcal sensibilization arteritis and two post-measles arteritis. No etiological agent was identified in the vessel walls. The necrotic lesions of the extremities appeared from five to 21 days after the clinical course of the infection. The lesions had the complete evolution in a period from one to four days. It was considered appropriate to start the heparinization in the evolutive period of the peripheral lesions in an attempt to reduce the ischemia by the interruption of the intravascular coagulation related to the vasculitis. In heparinized patients in whom the necrotic lesions did not extend completely in the extremities, the evolution to irreversible gangrene and limb loss did not occur.(ABSTRACT TRUNCATED AT 250 WORDS)
