Dynamic contrast-enhanced ultrasound with carbon dioxide microbubbles as adjunct to arteriography of liver tumors.

PURPOSE: The goal of the study is to evaluate utility of contrast-enhanced ultrasound (US) with carbon dioxide microbubbles in evaluation of hepatic lesions. METHODS: Twenty-eight patients with single or multiple hepatic lesions (11 hepatocellular carcinoma, 8 hemangiomas, 5 metastases, 1 adenoma, 1 focal nodular hyperplasia, 2 regenerative nodules) were examined. US exam was performed during intraarterial injection of 10 ml of CO2 through the same catheter employed for liver arteriography. The US exam was videotaped in its salient phases. Characteristics of enhancement were evaluated and correlated with histological findings or patient follow-up. RESULTS: Sonographic angiography clearly demonstrated vascularization of the lesions. Hepatocellular carcinoma, hemangioma, metastases, focal nodular hyperplasia, and regenerative nodules had very characteristic patterns. The injection of CO2 allowed detection of small additional nodules. CONCLUSION: Sonographic angiography can improve characterization and staging of hepatic tumors. Low cost and the simplicity of the technique should encourage further experimentation.

[The transcatheter recanalization of occluded portosystemic shunts].

UNLABELLED: The authors present their personal experience in percutaneous treatment of portosystemic shunt occlusion and stenosis by percutaneous transluminal angioplasty (PTA) and fibrinolytic local infusion. Twelve patients with portosystemic shunt stenosis or occlusion were percutaneously treated. In 8 patients only PTA was performed, 4 were treated with local fibrinolytic infusion, in 3 of the latter cases this treatment was followed by PTA. In all 12 patients recanalization was successful and non complications arose. Six patients died in the following 15 months, none due to rebleeding. In 5 of these patients the shunt was patent at post-mortem examination. In the 6 patients still alive in the follow-up period (2 to 25 months, mean 14.5 months) the shunt was patent in 4 and occluded in 2. IN CONCLUSION: percutaneous treatment with PTA or fibrinolytic local infusion is preferable in non-functioning portosystemic shunt; further surgery is always extremely risky in such patients.

[Hemobilia following biliary drainage: percutaneous treatment with arterial embolization and biliary fibrinolysis].

The Authors report a case of haemobilia following the performance of biliary drainage. Angiography of the celiac tripod and superior mesenteric artery was carried out in order to evidence the lesion and to perform, during the same session, embolization of the leaking vessel by means of fibrin sponge particles (Spongostan). Subsequent cholangiographic controls demonstrated the presence of bile ducts clots then treated by loco-regional infusion of urokinase. On the basis of the Authors' personal experience, the combination of loco-regional biliary fibrinolytic treatment and embolisation leads to the resolution of the cause of hematobilia and of retention jaundice.

[A gastric leiomyoma of conspicuous size. A case report].

The authors describe a large gastric leiomyoma with prevailing subserous growth. Conventional X-ray examination and endoscopy failed to diagnose the lesion properly. On the contrary, with CT it was possible to hypothesize the existence of leiomyoma with the correct definition of the outline of the lesion.

Gastric angiography: data for oesophagogastroplasty.

A report is presented on an angiographic study of the gastric arterial system conducted on 20 human stomachs taken from cadavers during routine autopsies. The aim of the study was to define the anatomical bases for the supply of blood to the isoperistaltic gastric tubule in oesophagogastroplasty operations. The study reveals that on its own the right gastroepiploic artery cannot ensure adequate vascularisation of the gastric fundus. The importance of pressuring the right hand section of the vascular arch along the small curve was also noted and is due to the constant presence of major anastomoses at antral level with the right gastroepiploic artery. The study also revealed the constant presence of a direct intramural anastomotic circulation between the right and left gastroepiploic arteries.

[Radiologic aspects of metastasis to the colon. Description of 4 cases].

The paper describes four cases of metastatic colon emphasizing its radiological aspect, represented by irregular and eccentric stenoses with stiffness and angling of the colon segments involved. In three cases, peritoneal carcinomatosis was also present and its radiological aspects (ascites, mesentery and omentum thickening, small intestine infiltration) were investigated by CT.

[Percutaneous treatment of ureteral obstructions with an internal double-J prosthesis. Initial long-term results].

Percutaneous insertion of ureteral stents is a widely accepted method for ureteral obstructions treatment. From 1981 to february 1986, we introduced 78 endoprostheses in 60 patients. Fifty-six with malignant tumours and 4 with benign stenoses. In 48 of those 60 patients follow-up is complete. In the patients with malignant obstructions the mean time of survival was 198 days. Twelve patients were still alive in february 1986, with a mean time of survival over 300 days. In 12 patients (25%) the stent became obstructed in a mean time of 96.8 days. The placement of ureteral stents offers an alternative treatment to the palliative urologic surgery.
