Background: The aim of this comparative clinical study was to evaluate the efficacy of the association of alphatocopherol, rutin, melilotus officinalis, and centella asiatica with oral administration in patients with chronic venous insufficiency., Methods: Thirty patients with chronic venous insufficiency have been randomized in two groups of fifteen subjects (control and treatment group). During the period of treatment the patients didn't wear elastocompressive stockings. The therapeutic efficacy and the clinical tolerability of this association have been valued with clinical-instrumental evaluations and by a control after 15 and 30 days. Functional bothers, cramps and the edema have been valued in function presence and of their gravity with a clinical-score between 0 and 4., Results: At the end of the observation period, a significant improvement of the clinical simptomatology was obtained, characterised by a diminution of the sovrafascial edema., Conclusions: The present study confirms previous clinical experiences regarding the described treatment and suggests its application in chronic venous insufficiency.

The authors enhance the current importance of the hemodynamic evaluation of the vascular carotid territory by means of Doppler-CV although the great development of the "real time" ultra sonographic imaging. Combined US/Doppler-CV technique is really useful in differential diagnosis of the severe obstructive disease of extracranial carotid arteries. The authors report the possibilities of pitfalls in diagnosis due to the limitation of devices employed or to the frequent anatomical variability featured by examination of severe obstruction of vascular carotid territory.

Among the anomalies of internal carotid artery, agenesis and aplasia recur with a low rate: only about sixty cases are reported in literature. We observed a case of aplasia of the left internal carotid in a 49 year old male suffering from hypertension and showing cerebro-vascular symptoms due to TSA pathology: it was studied with arterial angiography and duplex scanner. The angiographic examination raised a suspicion of left internal carotid thrombosis; on the contrary the duplex scanner revealed a correct diagnosis of carotid aplasia.

The Authors report on the use of non-invasive techniques in the preliminary evaluation of revascularization of the femoral-popliteal axis. The study of this pathology, for which surgery has become less and less frequent, being limited to the more serious cases, has greatly benefited by the use of H/R echography and of Doppler. These techniques, which remain complementary to angiography, have proved very important and reliable for their capacity to visualize the arterial lumen, an important element for the pre- and post surgical evaluation of vascular recanalization and of the relationship of continuity and continuity with the nearby structures.

Personal experience on the intraoperative use of HR echography for the evaluation of the immediate surgical results in carotid bifurcation T.E.A. is reported. It is already assessed that early failure in vascular surgery is due to technically incorrect procedures.
