[Sonography and phlebography in the investigation of the suprarenals (author's transl)].

Twelve patients were examined by sonography and phlebography; of these, ten had suprarenal tumours and two suprarenal hyperplasia. The value of sonography and its place compared with radiological examinations is discussed. Sonography is an informative method of screening and should be employed whenever there is clinical suspicion of enlargement of the suprarenals before other radiological methods are used.

[A method for percutaneous thin-needle biopsy of the pancreas aimed by ultrasound (author's transl)].

Percutaneous biopsy of the pancreas with a fine needle aimed by ultrasound was carried out on 26 patients with sonographically proven carcinoma of the pancreas. The accuracy of this method was correlated with other radiological techniques. Needle biopsy of the pancreas proved an informative and economical procedure, since the sonographic demonstration of a pancreatic mass otherwise requires additional radiological and endoscopic investigations.

[Sonographic topography of the pancreas (author's transl)].

Vascular abdominal structures can be demonstrated by the gray-scale-B-scan-technique. These vascular anatomical structures are important to differentiate pathological lesions from normal structures and to evaluate the localisation of space occupying lesions within the pancreas, liver and retroperitoneal space.

[Gray-scale sonographie. Vascular anatomy of the abdomen (author's transl)].

Gray scale sonography produces an exact topographical visualization of the following abdominal arteries and veins in longitudinal and transverse sections: Aorta, V. cava inferior, portal and splenic veins, mesenteric and renal vessels, coeliac trunk, intrahepatic systemic and portal veins. This allows for new possibilities in organ diagnosis with more exact localization of pathologic lesions.

[Clinical indications for abdominal sonography].

The clinical indications for ultrasonography in diseases of the abdominal organs are systematically presented and discussed. The use of the gray-scale technique leads to an appreciable improvement in diagnostic potential, due in particular to the demonstration of small vascular structures. Consistency of tissue structures, the topographic-anatomical relationship between organs, and localization of space-occupying lesions are readily determined by sonography with a minimum of discomfort and stress for the patient.

[Angiography in Crohn's regional enteritis. Its relation to conventional radiological, endoscopic and micro-angiographic findings].

There has been a definite increase in the incidence of Crohn's disease in recent years. A particular feature of this disease is the high incidence of recurrence after surgical removal of affected portions of the gut. This may be due to a resection carried out through a diseased segment and this stresses the importance of recognising early changes. This is not possible by conventional radiology (small bowel examination, barium enema) and is therefore an indication for pre-operative visceral angiography. The results obtained in ten patients, who subsequently came to surgery, were compared with the findings on conventional radiology and endoscopy. Angiography proved the best method for the early demonstration of inflammatory changes. This was confirmed by histological examination of the resected specimen.

[Inflammatory renal pseudotumors (author's transl)].

Inflammatory renal pseudotumors represent a not uncommon finding and frequently pose a difficult differential diagnosis. The importance of a thoroughful radiological evaluation with special reference to angiography is stressed.

[Congenital pseudotumors of the kidney (author's transl)].

Congenital pseudotumors of the kidney represent a relatively common urographic finding. Their pathological urographic, and angiographic characteristics are discussed. As a rule a definitive angiographic diagnosis of these benigne lesions is possible and chirurgical exploration is therefore rarly indicated.

[Gray-scale ultrasongraphy of the liver and gallbladder (author's transl)].

Better structural imaging of the liver with blood vessels can be achieved using the Gray-scale technique which delineates pathological processes better than the conventional B-scan-method. This technique enables a reliable diagnosic information. Due to its non-invasive character it can be utilized as a screening method or as an alternative or complementary examination to invasive methods.

[Selective pancreatic angiography and retrograde pancreatic cholangiography as a combined examination].

The diagnostic value of selective pancreatic angiography and retrograde pancreatic cholangiography used in combination was studied in 24 patients with chronic pancreatitis or pancreatico-duodenal carcinomas. This was done as a prospective study. The accuracy of the individual methods is 75% and 79% respectively; used in combination, a correct diagnosis is obtained in 91% of cases. The advantage of combining the techniques depends on the fact that they supplement each other.

Long-term follow-up of the Günther basket inferior vena cava filter: does mechanical instability cause complications?

PURPOSE: The Günther basket inferior vena cava filter (GBF) has been withdrawn from the market because of its mechanical instability, but a number of patients still live with the device. METHODS: In a two-center study, we evaluated the long-term follow-up of the GBF, based on clinical data in 78 patients, and on imaging studies including plain radiographs, Doppler ultrasound, angiography, or computed tomography (CT) in 50 patients. RESULTS: In a mean period of 3 years, pulmonary embolism was diagnosed in five patients (6.4%), with an overall rate of 0.02 embolic episodes per patient per year. None of these patients required hospitalization, and there were no deaths due to pulmonary embolism. Inferior vena cava thrombosis was documented in three patients (3.9%), and occlusive venous thrombosis at the access site in seven patients (9%). Spontaneous migration was documented in 43% of the examined filters and spontaneous disruption in 77%. Dislocated filter fragments were localized by CT in the adjacent retroperitoneum in 11%, in the aortic lumen in 2%, and in a peripheral pulmonary artery in 7%. None of the patients had symptoms attributable to filter migration or disruption. CONCLUSION: Our results indicate that the rate of clinically relevant complications with the GBF is no higher than with other vena cava filters. Because mechanical instability of the GBF had no clinical consequences, we conclude that patients who live with this device may be observed and treated in a manner similar to patients with other vena cava filters.

Diagnostic angioscintigraphic evaluation of malignant hepatic tumors before catheter embolization: determination of shunt, flow distribution, and reflux.

PURPOSE: The aim of this study was to evaluate quantitatively arteriovenous shunts in malignant liver tumors by injection of 99mTc macroaggregates of albumin (MAA) into the tumor-feeding artery after selective catheterization. METHODS: In 40 patients with malignant liver tumors (33 hepatocellular carcinomas and 7 metastases of colorectal cancer), a mean dose of 200 MBq 99mTC MAA was injected arterially during angiography. The embolized area and the lungs were then visualized using a gamma camera. A dedicated computer program calculated pulmonary shunt rates. RESULTS: The majority of patients (n = 30) with hepatocellular carcinoma showed small shunts varying from 0 to 15%; only 3 of these patients had shunts ranging from 18% to 37%. In patients with colorectal carcinoma metastases (n = 7) the shunt varied from 0 to 3% (2 +/- 1%), probably due to a physiological shunt in normal liver tissue in the embolized area. Importantly, the degree of shunt found bore no correlation to the tumor volume or to the pattern of vascularity on angiography. CONCLUSION: Diagnostic angioscintigraphy is a useful tool for pretherapeutic evaluation of the capacity of an individual tumor to retain particles and to measure extratumoral shunting; these are essential for therapy planning, as they can help to increase the safety and effectiveness of embolization.

Total anomalous pulmonary venous connection to the portal vein.

Anomalous pulmonary venous return represents a rare congenital anomaly with wide anatomic and physiologic variability. We report a case of the newborn with a rare form of total infracardiac anomalous pulmonary venous connection (TAPVC). The pulmonary veins draining both lungs formed two vertical veins, which joined to a common pulmonary trunk below the diaphragm. This venous channel connected to the portal vein through the esophageal hiatus. The diagnosis was suggested by color Doppler sonography and confirmed by intravenous digital subtraction angiography, which allowed definition of the anatomy.

CT-guided biopsy of pelvic masses.

CT-guided fine-needle puncture (FNP) was carried out in 74 patients with pelvic masses and resulted in a correct diagnosis in 36/45 patients (80%) with malignant disease. FNP was true-positive in 66.7% and false-negative in 20%. In benign and inflammatory pelvic space-occupying lesions, FNP confirmed the suspected CT diagnosis in all cases by cytology and bacteriology. CT-guided puncture should always be used complementary to CT when a mass of unclear etiology is present.
