[A case of renal infarction: clinical and anatomic contribution].

A case o/ renal infarction presenting with acute abdomen is reported. Due to the extended renal damage nephrectomy wasperformed. Macroscopic appearance o/ the kidney (prevalent cortical vascular inforction) and o/ the surrounding tissues (retroperitoneal edema and abdominal ascites) suggested a comparison with epidemie haemorrhagic flver. Vascular supp/y to the kidney, in such cases, depends on the perforating arteries which may increase in number and size

[Ambulatory phlebectomy: our experience].

The Authors report their experience of out-patient phlebectomy. Over a period of 5 years they have examined 186 patients (156 females, 30 males): 166 had micro- and extra-saphenic varicosities, while 20 had recurrent varices. Patients with ostium failure were excluded. Muller's out-patient phlebectomy implies an accurate mapping of varicosities, local anaesthesia, microincisions which are only exceptionally sutured. The Authors consider that an accurate elastic pressure bandage is indispensable and useful in order to improve the dynamics of the PVC and to avoid haemorrhages. Such a surgical technique bears aesthetic, economic and haemodynamic advantages

[Nephrogenic metaplasia. A particular clinical and anatomopathologic entity].

Two cases of nephrogenic adenoma are presented. The authors consider nephrogenic metaplasia as a reaction to inflammatory agents and point out the importance of differential diagnosis with nephrogenic adenocarcinoma, in which a different surgical procedure is requested

[Tietze's syndrome: importance of differential diagnosis and role of CT].

A case o/ Tietze's syndrome is reported. A 55-year-old woman had experienced left anterior cbest pain and tender swelling o/ the left second costosternal junction flr one month. CT Showed:j;0cal enlargement o/ tbe left second costai cartilage with partial calci cation. Six rnonths ater a complete recovery was registered and a second CT scan uras negative. These clinica! and CT findings are consistent with Tietze's syndrome

[Endoscopic surgery of chronic venous insufficiency (CVI)].

The endoscopic technique in chronic venous insufficiency is simple and almost complication free. Our preliminary results due to a good postoperative course and to a quick return to social activity induce the Authors to indicate this type of procedure as the best treatment in chronic venous insufficiency
