RESUMO
With the development of noninvasive haemodynamic methods, recognition of arterial insufficiency signs is possible also in cases in which, in old times, we just could suspect a psychogenic cause. Although this advance, discrimination permitted by this method can be improved. Eighty-eight supposed healty patients and eighty-four patients with arteriogenic erectile impotency (tested by arteriography) were included into an study, which results are presented in here. Analysis made, avoided the effect of envelleiment on haemodynamic parameters interpretation. For identification of patients which obstructive arterial defect can be cause of sexual disfunction, combination of systolic pressure determination and arterial flow velocity curves (by Doppler ultrasonography) is proposed. We recommend this method as a part of the multifactorial examen required by such type of patients.

An investigation, which goal is to evidencing AV fistulas in patients with a complicated postthrombotic syndrome, as well as to determinate the efficacy of noninvasive methods used for the study of AV fistulas in such patients, is presented. So, patients with a complicated postphlebitic syndrome interned into the Instituto de Angiología were studied. Twenty-five patients were included in the study, 9 of these patients (36%) had arteriovenous fistulas, arteriographically evidenced. Haemodynamic study do not support the evidence of such communications.

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.
