[Angioplasty of the deep femoral artery using a semirigid PTFE prosthesis. Experimental studies].

Underlining the importance of Profundus Femoral Artery and its capacity to make up for lower limb's haemodynamics during obliterative arteriopathy, the Authors conceive a funnel-shaped intravascular prosthesis, Goretex constructed (PTFE), to introduce, in case of obstruction, in the artery lumen with a suitable instrument. The research is performed through ten oldster dogs whose average weight is twenty-four kilograms. Isolated the deep Femoral Artery and carried out an arteriotomy of about two centimetres on the Common Femoral Artery, we bring the prothesis in Profundis Femoral Artery and we fix it to the wall of the Common Femoral Artery with 8/O microsurgical dots. After thirty days, the arteriographic test shows the patency of the endoprosthesis with normal peripheral flow in nine animals out of ten. By virtue of this preliminary experiment, the Authors point out the semplicity of this intervention, also feasible in local anaesthesia, the good tolerability of the prosthesis and its perfect integration with the surrounding arterious wall, without shifts or dissecting laminar flows between the external prosthesis wall and the vessel lumen of the animal.

[Etiopathogenetic and histopathologic aspects of acute necrotico-hemorrhagic pancreatitis in experimental animals].

In this study, the Authors have provoked experimentally acute pancreatitis in the rat by different methods, in order to find out morphological modifications of the pancreas in the initial stage of the disease. In case of biliary and pancreatic duct obstruction with pure pancreatic reflux, both oedema and inflammatory infiltrations were evident, whereas, in the presence of biliary reflux too, more serious histological features were detected. In conclusion, the first sign of alteration in acute pancreatitis could be represented by the association of intraductal hypertension and pure pancreatic reflux.

Evaluation of postoperative blood coagulation changes in elderly patients undergoing major surgery.

18 elderly patients submitted to major surgery for malignancies or other disease were studied to assess the relationship between changes of blood coagulation factors and inhibitors in the early post-operative period and the appearance of lower limb deep vein thrombosis. A decrease in serum antithrombin III (AT III) Protein C antigen (PC: Ag) and Plasminogen activity (PLG) levels from the second to the fourth postoperative day, together with a simultaneous increase in serum fibrinogen (FG) and von Willebrand Factor (vWF:Ag) antigen levels was observed. In 8 patients, PC:Ag levels dropped below the limit considered at risk to develop DVT (less than 60 U/dl). A patient with the lowest PC:Ag levels had deep vein thrombosis From the analysis of data it was concluded that in the postoperative period, blood coagulation changes occur in elderly patients, predisposing to the risk of deep vein thrombosis.

[Primary carcinoma of the cystic duct: a case report and review of the literature].

The Authors, after a short introduction concerning the primary carcinoma of the cystic duct and the exact definition according to Farrar's criteria, report a case occurred to their observation, the 35th case of international literature. In particular the importance of some hemato-clinical parameters and instrumental investigation (ERCP, angio-CT) to underlined in order to surgical indication. In the case here reported cholecystectomy uses informed with partial resection of the hepato-choledochus and excision of some periductal and pericholedochus lymph nodes. Finally, the Authors discuss about clinical data and diagnostic and therapeutic trends, on the case of their experience and literature review.

[Laparoscopy in an abdominal emergency: the diagnosis and therapy in 3 clinical cases of acute abdomen].

Authors report three cases of acute abdomen due a probable appendicitis and submit to laparoscopic procedure. In the first case acute abdomen was due to a bowel obstruction secondary to an ectopic pregnancy; in the second case acute appendicitis was associated with a rare congenital malformation (atresia of uterus); in third case acute abdomen was due to a rare case of torsion of accessory spleen in an adult. In all the cases laparoscopy demonstrated the elective procedure in urgency, permitting the diagnosis and the surgical treatment of acute abdomen with the post-operatory advantage of the technique.

[The laparoscopic treatment of a rare case of intestinal obstruction due to an ectopic pregnancy].

A rare case of intestinal occlusion due to primary abdominal pregnancy is described. Laparoscopy revealed normal appendix and bowel obstruction by adhesion between the last ileal loop and cecum. The adhesion started from a neoformation (diameter 2 cm) localised on the mesenteric side of the ileum, about 30 cm from the ileocecal valve. A resection of the adhesion and dissection of the neoformation were performed. Laparoscopic procedures lasted 30 minutes. Histologic examination of the specimen revealed to be an ectopic pregnancy. The laparoscopic technique permitted to verify the diagnosis and perform the treatment of the abdominal pregnancy in absolute conditions of safety, maintaining the fertility of the patient (actually she is presenting a regular pregnancy).

[Gasless laparoscopic cholecystectomy. Selective intervention in a high surgical risk patient].

Disadvantages related to CO2 pneumoperitoneum in high risk patients (anesthesiologic classification in III and IV ASA), have led to the development of the abdominal wall retractor, a device designed to facilitate laparoscopic surgery without conventional pneumoperitoneum. A case of a patient with acute cholecystitis, well-compensated liver cirrhosis, and high respiratory and cardiologic risk (ASA III class), submitted to laparoscopic cholecystectomy with gasless technique is reported.

[The diagnostic-therapeutic picture in liver injuries: a review of the literature and clinical cases].

Approximately 80% of liver trauma cases have a good prognosis and do not create decision-making problems for the surgeon, while in the remaining 20% the correct choice still represents a problem. Recently there has been a trend toward more conservative surgical management with emphasis on hemostasis and debridement, as well as a move toward a non-surgical alternative (surgical abstention) where feasible, relying in such cases on first-line CT scans for trauma evaluation. We report 51 cases of liver trauma observed in the period 1985-1993 graded according to the AAST Liver Injury Scale as follows: 12 grade I lesions (23.5%), 7 grade II lesions (13.7%), 19 grade III lesions (37.3%), 7 grade IV lesions (13.7%), and 6 grade V lesions (11.8%). In managing these cases we relied on two first-line diagnostic procedures: diagnostic peritoneal lavage (DPL) and CT scans. DPL, performed on 10 blunt trauma victims with unstable vital signs, was positive in 7 who thus underwent immediate surgery, and negative in 3 who subsequently underwent CT scan. Another 14 blunt trauma victims with stable vital signs underwent first-line CT scanning. In the event of a CT grade III or IV lesion patients underwent surgery, while patients with a CT grade I or II lesion were followed expectantly. Deaths (14) occurred only among patients with grade III or IV lesions (including 9 multiple trauma victims) who underwent surgery.

[Arteriomegaly: a clinical case report and review of the literature].

The authors report a case of arteriomegaly and underline the importance of a correct diagnosis. A review of the literature, in fact, confirms the incidence of the disease is higher than usually believed. Therefore, a complete diagnostic evaluation is necessary to recognize the disease and assure the adequate treatment.
