RESUMO
This study was designed to describe the presence of calcifications according to the clinical features of the diabetic patient and the hemodynamics of the calcified arteries. With this purpose, 197 lower limbs from diabetic patients (type I and II) and carbon-hydrate intolerant patients, were studied. In all of the patients, the pressure ratio leg/arm was measured. On the same way, the arterial flow velocity was recorded using the Doppler ultrasonography on the pedia and postero-tibial arteries. The arterial calcifications, evident on the radiography of the foot, were more frequent between the type I patients and the neuro-infections diabetic foot. According to the hemodynamics point of view, we found a trend of association of more pathologic arterial flow velocity curves with the presence of calcifications (specially on the intima layer). It was also remarkable that an arterial incomprensibility was always associated with arterial calcifications.

The present study was designed in order to analyze our experience in surgical treatment of 18 patients with abdominal aortic aneurysm associate to a high surgical risk from 1982 (January-February) to 1988, both included. Selection criteria and surgical technical aspects were established. The patient age ranged from 60 to 82, with an average age of 75 +/- 7.5 years. The most frequently associated pathology was hypertension disease, followed by cerebrovascular disease and ischemic cardiopathy. Two patients died during surgical procedure. Fifteen patients, from the 16 surviving, suffered a complete thrombosis of their aneurysmatic sac one week after the induced thrombosis, by the ligature of afferent arteries of their aneurysm (iliac arteries). Only one patient suffered a second operation, 4 months after the initial procedure (partial exclusion) during which a total exclusion of aneurysm by infrarenal aortic ligature was performed. The successful operatory rate was of 14/15 (93.3%), with a mortality rate of 2/18 (11.1%). References are reviewed and our results commented.
