[Bilateral symmetrical obliteration syndrome of the subclavian-brachial system in the elderly female]. / Bilateral-symmetrisches Obliterationssyndrom des Subklavia-Brachialis-Systems bei der älteren Frau.

The case of an elderly woman is reported, presenting with a bilateral-symmetrical occlusive disease of the subclavian-brachialis-axis in combination with Horton's arteriitis. Early intraarterial thrombolysis may be an appropriate first-line treatment to favourably influence complicated coagulation phenomena.

[The place of nuclear medicine procedures in clarifying the state of gastrointestinal bleeding--radionuclide monitoring]. / Stellenwert nuklearmedizinischer Verfahren in der Abklärung gastrointestinaler Blutungsaktivität--Radionuklid Monitoring.

Radionuclide studies today can specify the actual state of gastrointestinal bleeding. "Radionuclide monitoring" characterises a method that allows a long-term surveillance of the patient for hours or even days (sequential scintigraphy). Labelling of the intravasal space is best met by in vivo/vitro labelling of the red blood cells with 99mTc, "Radionuclide monitoring" may positively influence current concepts of diagnosis or treatment control of patients suffering from gastrointestinal bleeding.

[Schwannomas of the stomach]. / Schwannome des Magens.

One benign and one malignant schwannoma of the stomach are presented. The gross appearance, degree of local invasion and the complications are demonstrated by double-contrast radiology technique and CT. Benign schwannomas can only be distinguished from the malignant ones on the basis of histological and immunohistochemical criteria.

[Abscess of the cervical soft tissues and the mediastinum resulting from an infected jaw cyst]. / Abszess der Halsweichteile und des Mediastinums ausgehend von einer infizierten Kieferzyste.

A woman is described in whom an infected radicular cyst of the mandible resulted in a cervical phlegmon with abscess formation and spreading into the superior mediastinum.

[An atypical finding in a bone cyst]. / Atypischer Befund einer Knochenzyste.

Atypical radiologic and scintigraphic findings of a benign bone cyst in a 49-year old male are presented. The cyst is surrounded by a polygonal thick uneven sclerotic rim and shows radionuclide uptake.

[Arthrography--expanded diagnosis in capsule-ligament injuries of the upper ankle joint]. / Arthrographie--erweiterte Diagnostik bei Kapsel-Band-Verletzungen des oberen Sprunggelenkes.

Arthrography was performed in 563 cases of ankle injury to determine its diagnostic information. No complications occurred in our study. Experiences are described and indications for arthrography are pointed out. Stress radiography using a sophisticated apparatus and reproducible amounts of pressure does not have the diagnostic accuracy of arthrography. Arthrography of the ankle joint makes it possible to diagnose ligament rupture and classify injuries by negative stress radiography.

[Radionuclide monitoring of gastrointestinal bleeding activity]. / Radionuklidmonitoring gastrointestinaler Blutungsaktivität.

Radionuclide monitoring was done in 50 patients to assess gastrointestinal bleeding, activity and location. Monitoring with 99m-Tc-in vivo-labelled erythrocytes was performed as sequential scintigraphy in increments of 1-2 hours up to 62 hours. 23 patients without active GI bleeding were correctly identified. 27 patients showed pathologic activities in abdominal blood-pool scintigraphy. In 25 patients peristaltic movement of these activities were seen--in each case we correctly diagnosed active GI bleeding. In 2 patients the activity stayed for a longer period in the same location--one patient had a liver hemangioma, the other patient had an aneurysm of the superior mesenteric artery. The great impact of radionuclide monitoring on diagnostic and therapeutic management of gastrointestinal bleeding is emphasized.

[Primary oxalosis in adulthood. Scintigraphic and radiologic documentation of oxalosis nephropathy, oxalosis arthro-/enthesiopathy and oxalosis cardiomyopathy--review of the literature]. / Primäre Oxalose im Erwachsenenalter. Szintigraphische und radiologische Dokumentation der Oxalose-Nephropathie, der Oxalose-Arthro-/Enthesiopathie und der Oxalose-Kardiomyopathie--Literaturübersicht.

Clinical, radiographic and scintigraphic abnormalities in primary oxalosis of a 52 years old female are demonstrated. Severe oxalosis-nephropathy and oxalosis-arthropathy/enthesiopathy are shown. For the first time an intense myocardial uptake of 99 m Tc-HDP and 99 m Tc-MDP is described in connection with oxalosis. It is suggested that in the appropriate clinical setting this pattern may be suggestive of oxalosis-cardiomyopathy. Review of literature.

[Demonstration of complications caused by implantable catheter systems in regional arterial infusion therapy of tumors of the pelvis (bladder cancer). Radiologic and nuclear medicine control possibilities]. / Darstellung komplikativer Situationen bei implantierbarem Kathetersystem zur regionalen arteriellen Infusionstherapie von Tumoren im Becken (Harnblasen-Karzinom). Radiologische und nuklearmedizinische Kontrollmöglichkeiten.

Loco-regional intra-arterial infusion chemotherapy is gaining momentum in modern tumor therapy. Cytostatica are delivered by an implantable system. Because of high tissue toxicity of chemotherapy functioning of the system must be assured and controls should be simple and reliable. The system implanted in 10 pat. with bladder-cancer (p T3 a-b) was checked by radiological and radionuclide diagnostic means before each chemotherapy. Both techniques proved valuable. Good and deficient functions are demonstrated.

[Neoplastic thrombosis from a uterine cancer via the ovarian vein. Venous collateralization via the vasa vasorum in occlusions of the renal vein and the inferior vena cava]. / Geschwulstthrombose eines Uteruskarzinoms über die V. ovarica. Venöse Kollateralisation über vasa vasorum bei Verschluss der V. renalis und der V. cava inf.

Renal vein and inf. vena caval occlusion by neoplastic thrombus mediated by the ovarian vein from an occult uterine carcinoma is an extraordinary diagnosis. The special angiographic feature consists in demonstrating the renal venous drainage via vasa vasorum of the renal vein and inf. vena cava.

[Percutaneous transluminal angioplasty in Brescia-Cimino shunt insufficiency]. / Perkutane transluminale Angioplastie bei insuffizientem Brescia-Cimino-Shunt.

Forty-eight patients with failing arteriovenous dialysis fistulas were evaluated in an 18-month period. Forty-six of dialysis access fistulas were of the Brescia-Cimino type; two were fistulas in the upper forearm. PTA was technically feasible in twenty-three patients (44%). 54% dilatations with polyethylene balloons were initially successful and patent at 3 months; 43% were patent at 6 months; and 24% after more than 9 months. Two complications were encountered. PTA is recommended in Brescia-Cimino type dialysis fistulas, as the procedure prevents damage to the arterial and venous vessels suitable for a new fistula at the same forearm. The procedure may be performed on an outpatient basis.

[Inoperable cancer of the left hepatic duct--CT criterion and relation to angiography findings]. / Inoperables Karzinom des Ductus hepaticus sinister--CT-Kriterium und Zuordnung des angiographischen Befundes.

In the diagnosis of pancreaticobiliary tumors, computerized tomography is becoming the routine examination method. Occasionally, due to the complexity of anatomical factors, diagnosis of tumor origin and operability is difficult. Vascular invasion, as an indicator of the inoperability of a cystic duct carcinoma, is demonstrated angiographically and compared with the CT finding of a preaortic soft-tissue shadow.

[Partial Budd-Chiari syndrome with Zahn infarct of the liver in venous transmitted tumor thrombosis of a uterine cancer]. / Partielles Budd-Chiari-Syndrom mit Zahnschem Infarkt der Leber durch venös fortgeleitete Geschwulstthrombose eines Korpuskarzinoms.

Aspects of a patient's case are reported in which tumorogenic thrombosis, originating from a clinically occult uterine carcinoma, was transmitted via the ovarian vein into the inferior vena cava, thus leading to hepatic vein occlusion (partial Budd-Chiari syndrome) with hepatic infarct. The specific angiographic signs of Zahn's infarct are described and interpreted.

[Sacroiliac distorsion or subluxation--a medically established concept? X-ray diagnosis--bone scintigraphy]. / Sacroiliacale Distorsion bzw. Subluxation--ein medizinisch gefestigter Begriff? Röntgendiagnostik--Knochenszintigraphie.

50 patients with complaints in the region of the sacroiliacal joints and the hip, but negative radiographs following injury to the pelvis were investigated by bone scan. Scintigraphic diagnosis always showed involvement of the pelvis ring other than the apparent fractures. Together with the clinical symptoms scintigraphic findings are interpreted as sacroiliacal strain or subluxation. Additional injuries to the acetabulum and to the lumbosacral joints may be present. The patients' complaints are explained, the injuries are localized and documented.

[Occult damage to the femur neck in senile-/inactivity-osteoporosis]. / Okkulte Verletzungen des Schenkelhalses bei Alters-/Inaktivitäts-Osteoporose.

Fractures of the femoral neck in elderly patients are often a complication in osteoporosis. Diagnosis of fractures with displacement and compression of fragments is quite easy. The negative radiograph in old patients complaining of hip pain is generally considered a characteristic feature of presenile osteoporotic pain. Clinical examples present patients with hip pain caused by occult injuries of the femoral neck. They should be regarded as imminent fractures and adequately treated. Bone scan is very helpful in the early detection of such occult osteoporotic injuries.

[Bile leakage, bile ascites and bilioma--nuclear medicine diagnosis--demonstration of typical cholescintigraphic findings]. / Galleleck und Galleaszites bzw. Biliom--eine nuklearmedizinische Diagnose--Darstellung typischer choleszintigraphischer Befunde.

Cholescintigraphy (hepatobiliary sequential scintigraphy) with 99m Tc-marked IDA derivatives results in a specific identification of bile in free intraperitoneal fluids (bile ascites) or encapsulated intraperitoneal fluids (bilioma). To detect or exclude a biliary leak, cholescintigraphy was performed in 42 patients. In contrast to sonography and CT ("anatomical imaging"), which are capable of detecting an intraperitoneal accumulation of fluid with high sensitivity, cholescintigraphy ("functional imaging"), alone can help to identify the presence of bile in such fluids, both specifically and on a non-invasive basis. Modern gamma cameras are of such high sensitivity that they can identify even the most minute of activity (bile) quantities with satisfactory anatomic allocation.
