[Echocardiographic study in congestive cardiomyopathy].

Single-dimensional echocardiography was used in the study of 15 patients with congestive cardiomyopathy. The main signs for the diagnosis of this disease and its differentiation from atherosclerotic coronaropathy were determined. Mitral and aortic echograms were examined along with the ventricular parameters in order to assess their importance in the study of ventricular function.

['Incidentaloma' in inguinal hernia surgery].

Adult Granulosa-Cell Tumor (GCT) is an uncommon ovarian malignancy. The clinical course is characterized by slow growth with late recurrence. A variety of clinical and pathologic parameters have previously been evaluated for prognosis with inconclusive results. The aim of this study was to report a case of a granulosa-cell tumor of the ovary that recurred 25 years after first surgery. The clinical course and histopathology of the case were reviewed and a literature search for other reported cases was performed.

[Sigma's stenosis. Clinical, diagnostic and therapeutical problems].

Sigma's stenosis represent a frequent pathology, but its very difficult to have a pre-operatory diagnosis about the nature of these stenosis, not withstanding the introduction of more sophisticated instruments of diagnosis. In this work we present 9 cases of sigma stenosis; some of these with a common etiology and other very interesting for their rare and unusual origins. The patients were underwent to a different timing of diagnosis and therapy based on clinical history and diagnostic hypotheses; our experiences demonstrate that the clinical intuition is really useful for a correct diagnosis in the patients with a sigma's stenosis and consequently, in order to plan the correct therapy.

[Spinal cord ischemia following subrenal aortic clamping].

The paraplegia caused by an aortic clamping just below the Renal artery is a rare but very complication in aortic surgery. Such a complication is even rarer if we consider the few cases reported in literature following a reconstructive surgery for occlusive chronic diseases of aortiliac axes. The authors have studied the case of a patient bearing the syndrome of Leriche; this one had an aortic clamping below the kidney and soon after developed an acute ischaemic syndrome below the spinal medulla with flaccid paraparesis, anal and vesical sphincteric diseases and persistence of deep tactile sensibility. After a reconstruction of vascular anatomy of the medulla they emphasize the importance, in such a disease, of the "arteria radicularis magna" of Adamkievicz and its place of origin. After they discuss the severe physioopathologic moments that are connected: with the direct ischaemia following aortic clamping in the cases where the arteria radicularis magna rises at a level lower than the clamping itself; with the embolism or thrombosis caused by surgical manipulation peroperatively (it might be the cause of paraplegia more frequent in aneurysmectomia surgery); with the severe hypotension per- and post operatively for the existence of arteriosclerotic disease of the lumbar arteries. Finally they analyses preoperatively diagnostic possibilities and per operatively methods used in preventing this sort of complication.

[The biosynthetic Omniflow prosthesis: preliminary experience].

The Omniflow biosynthetic prosthesis is made by a polyester net set on a silicon mandrel and planted on the sheep's back in order to from a tube of collagen that is fixed by glutaraldehyde at the moment of removing. This idea comes from the experience made in using glutaraldehyde as biologic fixative employed for the first time in the fixation of the cardiac valves by Carpentier in 1976 and in using nets of synthetic material set on a mandrel in man by Sparks in 1986, to form a tube of collagen to be used as a vascular prosthesis. Such a prosthesis has the advantage of the natural collagen deprived of its immunogenicity and also the increased resistance due to the polyester net. The authors report their experience in three arteriopathic patients employing Omniflow prosthesis used for the manufacturing of femoropopliteal bypass, a femoro-femoral bypass and for the substitution of an infected branch of axillobifemoral bypass. They describe the handling and the technique for the right application to avoid immediate complications, among which the most dangerous is the acute obstruction. Then they discuss the results which are encouraging even if the fellow up is too short. For such a reason they report the casuistic with long distance results obtained by the use of the same prosthesis by Raithel et Al., one of the largest experience in literature.

[Peroperative endoscopic papillotomy in a patient with an abdominal aortic aneurysm and biliary calculi].

The authors report a case of abdominal aortic aneurysm associated with biliary tract lithiasis. The need to simultaneously treat both diseases is stressed. A technique which involves endoscopy during open surgery in order to prevent contamination is illustrated. The technique used together with other manoeuvres is part of a methodology aiming to broaden indications to the treatment of abdominal diseases associated with vascular diseases, limiting at the same time the risks of prosthetic infection.
