[Liver transplantation, vascular complications, role of imaging, percutaneous therapeutic possibilities].

Duplex Doppler ultrasound should be the first investigation when a vascular complication is suspected. Serial examinations may increase sensitivity. Color imaging enhances identification of small vessels and increases specificity. Angiography is not necessary unless an pseudoaneurysm is suspected. When duplex Doppler ultrasound is abnormal, angiography is performed to evaluate the possibility of treatment. Endovascular therapeutic procedures appear to have a limited field of application in comparison to percutaneous biliary procedures. Hemostatic embolization or dilatation of vascular strictures can be used either as definitive treatment or while waiting for a new graft to be performed under better conditions.

[Use of a constant-flow 2-phase injector for abdominal scanners in 60 patients].

The intravenous injection of a contrast medium is carried out in more than 80% of all the patients undergoing abdominal CT. The use of a constant-flow two-phase injector has several advantages in practice: possibility to vary the injections, safety, easy use, reproducibility, overall quality of the results and possibility to reduce the dose of contrast medium. The routine use of such equipment seems to be indispensable at present.

[Intravenous digital angiography in the kidney transplant patient: results of a systematic prospective study in 164 patients].

A prospective study on digital intravenous angiography (DIVA) in 164 renal transplant recipients performed from 1 to 2 months post-transplant was conducted to assess its usefulness in the screening of post-transplant renal artery stenosis (RAS). DIVA was uninterpretable in 32 patients (19%) on technical grounds (blood vessel or metallic clip superimposed). The global prevalence of RAS was 10.7% in 132 patients whose DIVA was informative. No correlation was found between the prevalence of RAS and renal function. The prevalence of RAS was significantly higher (p less than 0.01) in the hypertensive (26%) than in the normotensive group (6.6%), but RAS may occur in normotensive or even asymptomatic patients. Our data confirm the usefulness of routine post-transplant renal artery screening but arterial way will be preferred.

[Intrahepatic localization of a pancreatic pseudocyst].

Intrahepatic false cysts of the pancreas are rarely observed, and only 5 cases have been reported in the published literature since 1965. Recent publications concerning false cysts located adjacent to or within abdominal parenchymas are reviewed. The most common sites are renal and splenic. Radiologic images usually simulate an intravisceral tumoral lesion, even when the false cyst is in contact only with the parenchyma, because of inflammatory changes. Diagnosis depends on complete radiographic exploration of the pancreas, including ultrasonography, a CT scan, and coeliomesenteric arteriography if possible, to detect possible signs of pancreatitis. Ultrasound guided cyst puncture is of marked diagnostic and possible therapeutic value.

[Echotomography in the study of Spigeli's lobe. Normal and pathologic aspects. Surgical therapeutic effects].

Ultrasonographic examination of the liver segment I, based on limiting vascular ans fissural elements, requires detailed knowledge of hepatic anatomical and organizational features. Findings are of two-fold interest for pre-operative assessment. Firstly, as a complement to essential arteriography it can establish the integrity of the segment when considering hepatectomy for liver tumors, and secondly it enables application of modifications in techniques for portocaval anastomoses. The data obtained can also assist diagnosis in cases of cirrhosis and Budd-Chiaris syndrome.

[Hepatic calcifications in isolated necrotizing, granulomatous hepatitis due to Brucella. A case report and review of the literature (author's transl)].

A case of isolated necrotizing, granulomatous hepatitis of Brucella origin is discussed, together with 6 similar cases reported in the published literature. The clinical picture is dominated by the history of the patient (occupation, geographical location), fever, right hypochondrial pain, and altered general condition. Radiological examination shows characteristic calcifications. Diagnosis is confirmed by serology, Brucella suis usually being involved. Pathological appearances are typical : large foci of hepatic necrosis surrounded by marked inflammatory zones with histiocytic cells arranged in palisades. The only possible treatment is surgical.

Ultrasonic diagnosis of primary carcinoma of the gallbladder: a review of 16 cases.

Sonographic findings in 16 patients (10 women, six men) with surgically documented gallbladder carcinoma are reported. Two principal forms are described: localized infiltrating, or fungating, tumors (eight patients) and diffuse tumors infiltrating the entire gallbladder wall (eight patients). In all cases, the tumors were adenocarcinomas. Eleven patients also had cholelithiasis. Contiguous extension and metastasis did not correlate with tumor size. The difficulties encountered an the differential diagnosis are discussed in relation to the different sonographic appearances.

[Ultrasonography characteristics of primary cancers of the gallbladder. A report on 16 cases (author's transl)].

Primary cancer of gallbladder was detected by ultrasonography in 16 patients (10 women, 6 men), and confirmed at operation. Two main types of lesion were found: 8 localized forms (infiltrating or vegetating), and 8 diffuse forms with infiltration of the gallbladder wall. The lesion was an adenocarcinoma in each case, and there was associated lithiasis in 11 patients. Extension by contiguity or metastases is independent of the size of the cancer. Problems related to etiological and differential diagnosis of these lesions are discussed in relation to the different ultrasonography appearances observed.

[Acute emphysematous cholecystitis. One case (author's transl)].

Acute emphysematous cholecystitis is a rare condition. Its preoperative diagnosis is based upon radiological studies which should include a film in the dorsal decubitus position, a lateral and a film in lateral decubitus with the ray horizontal. The presence of air within the gall bladder lumen; and in a part or all of the wall. Additional findings: the presence of air in the peribiliary space; the presence of gas within the biliary tract, rarely reported, is of special interest in the case reported here. Gangrenous cholecystitis must be differentiated essentially from: 1 degree an internal biliary fistula 2 degrees air in a neighbouring organ 3 degrees lipomatosis.
