[Role of ultrasonics in the diagnosis of 5 hydatid cysts of the heart].

Clinical and ultrasonographic findings in five patients with cardiac echinococcosis are presented. In each case chest film showed abnormal shape or enlargement of the heart shadow, with calcifications in three patients. In four cases, echocardiography was suggestive of a cystic lesion. Echocardiography associated with plain chest film seems to be a reliable technique for positive diagnosis and follow up after treatment. However, it is insufficient for preoperative work up in which selective coronary arteriography remains the cardinal procedure.

Anatomical bases of echography of the liver. Applications in peroperative echography.

Peroperative echography is bound to play an increasingly important role in indications for hepatic exeresis, particularly as this type of surgery is anatomical and patterned. It is not easy however to have a clear idea of the stereo-spatial representation of one segment or another when the liver is in situ. The aim of this investigation is to define precisely, with the help of echographic sections, the topography of the different hepatic segments, thereby enabling the surgeon to carry out a complete and systematised exploration. It provides the surgeon with information which has not been accessible until now with classic peroperative explorations.

Follow-up electron beam CT for the management of early phase Takayasu arteritis.

PURPOSE: The purpose of this work was to assess typical findings of Takayasu arteritis on serial CT examinations following therapy. METHOD: Serial CT studies were performed on 16 patients with early phase Takayasu arteritis. Mural or luminal changes of the aorta on successive CT scans were compared with clinical data. RESULTS: Vascular lesions progressed during follow-up in 6 of 16 patients. In one patient, progression of lesions was symptomatic. In the other five of six patients with worsening lesions, vascular progression occurred without new clinical symptoms and was first identified on CT scans. One of these five had dilatation of the ascending aorta and required aortic repair. Four others had progression of stenotic vascular lesions leading to changes in medical treatment only or in combination with either surgery or angioplasty. For two of them, CT examinations showed decreased mural lesions after changes in medical treatment. CONCLUSION: CT examinations performed in treated patients with Takayasu arteritis demonstrate either regression, stabilization, or progression of vascular lesions. Serial CT examinations may thus be useful for evaluating response to treatment.

[Peroperative ultrasound scanning of the pancreas].

Intraoperative realtime high resolution ultrasound scanning of the pancreas seems to be a new and promising procedure. We have performed it in 28 patients: the normal ultrasound picture of pancreatic ducts and parenchyma was defined in 9 patients without pancreatic disease; in 19 patients with pancreatic disease, intraoperative ultrasound was compared with preoperative ultrasound examination. Seven of 8 patients with pancreatic carcinoma and 4 of 6 with calcifying chronic pancreatitis had positive findings, respectively. In 3 cancer patients, intraoperative ultrasound investigation avoided a long and unavailing dissection of the tumor by revealing extensive spread. In selected cases, intraoperative sonography allowed to characterize and to localize pancreatic carcinoma: portal vein invasion, relationship of the tumor to the duct of Wirsung and small hepatic metastases. In chronic pancreatitis, intraoperative ultrasound information concerning the dimensions of the pancreatic duct, the structure and the localization of pseudocysts was comparable to that obtained by radiological opacification. Furthermore, intraoperative ultrasound exploration guided proper incision and evacuation of pancreatic pseudocysts in two patients. Operative ultrasound seems to us to be mandatory during pancreatic surgery. Further experience with this technique is needed in a larger number of patients. However, we believe that it could replace intraoperative cholangiography and pancreaticography in the assessment of extension and complications of pancreatic disease.

[Experimental model of pulmonary bipartition with bilateral lobe transplantation in dogs and application to clinical medicine].

The crucial need for donors of paediatric or small sized organs has been a great obstacle to overcome in organ transplantation in children or small adults. Some progress in adapting size of the donor organs has been achieved with surgical procedures for reducing the size of donor organs, partial transplantation (single lobe of the liver or the lung) and liver partition, offering a partial solution to the insufficient supply of paediatric organs. We propose an experimental model in the dog of lung partition associated with monolateral (series I) or bilateral (series II) lobe transplantation. The results have been encouraging both in terms of quality of healing and in morphological and functional adaptation of the transplanted lobes, allowing us to apply this technique of lung partition and bilateral lobe transplantation in human patients. The outcome has been excellent in the first case after 18 months follow-up.
