The treatment of aortic aneurysms with endovascular stents or stent–graft prostheses is receiving increasing attention as an alternative to major abdominal surgery. To define the clinical value this technique, we prospectively studied use endoprostheses made nitinol and covered polyester fabric for infrarenal aneurysms.

Percutaneous transluminal renal angioplasty is a safe and effective treatment for nonostial stenoses of the arteries, but it has proved to be disappointing ostial stenoses. Therefore, we prospectively studied use intravascular stents critical after unsuccessful balloon angioplasty.Stainless-steel endoprostheses were placed across 74 renal-artery located within 5 mm aortic lumen in 68 patients with hypertension. Twenty had mild or severe dysfunction. The indications stent placement elastic...

Pheochromocytoma is a feature of two disorders with an autosomal dominant pattern inheritance -- multiple endocrine neoplasia type 2 (MEN-2) (with medullary thyroid carcinoma and hyperparathyroidism) von Hippel-Lindau disease angioma the retina, hemangioblastoma central nervous system, renal-cell carcinoma, pancreatic cysts, epididymal cystadenoma). The frequency these syndromes in patients pheochromocytoma not known.

To evaluate use of the transjugular intrahepatic portosystemic shunt (TIPS) as a nonsurgical approach for management Budd-Chiari syndrome (BCS).Twelve patients with fulminant (n = 2), subacute 5), or chronic 5) BCS underwent TIPS placement. Hepatic venous obstruction was demonstrated at computed tomography and color duplex sonography. confirmed histologically in all patients. Hemodynamic parameters clinical characteristics were assessed.TIPS creation successful Treatment reduced portal...

Breath-hold MR cholangio-pancreaticography using the RARE method was evaluated as a noninvasive alternative to direct in 30 healthy volunteers and patients with various diseases of respective duct systems. In contrast 3D cholangiography, MRCP generates projection images requiring 4-s acquisition time no postprocessing. Diagnostic information gained from cholangio-pancreaticograms fully equivalent that conventional x-ray imaging by invasive procedures. Additional whenever endoscopic access...

To evaluate the use of transjugular intrahepatic portosystemic shunt (TIPS) and local, low-dose thrombolysis in treatment complete, noncavernomatous portal vein occlusion.TIPS implantation recanalization was attempted seven patients with obstruction recurrent variceal bleeding. TIPS placement followed by thrombolytic therapy to restore venous blood flow. Hemodynamic effects clinical characteristics after procedure during follow-up were assessed.The trunk successful all patients. The reduced...

Hepatocellular carcinoma (HCC) is one of the most severe sequelae chronic liver disease. The only potentially curative therapeutic options are surgical resection and orthotopic transplantation. In HCC patients, however, at clinical presentation tumors unresectable because multicentricity or poor hepatic functional reserve due to pre-existing cirrhosis not transplantable too advanced tumor stage co-morbidity. practice, therefore, percutaneous ethanol injection (PEI) transarterial...

To evaluate the long-term results of recanalization occluded iliac arteries with local low-dose thrombolysis, angioplasty, and, if necessary, stent implantation.Forty-seven patients acute or chronic occlusions common external artery, both, underwent thrombolysis (n = 47), percutaneous transluminal angioplasty (PTA) (with balloon dilation [n 43] and rotational 30] in whom a retrograde was performed), needed, intravascular placement 18). Follow-up lasted 3-53 (mean, 21) months.The primary rate...

Background: Cardiopulmonary bypass (CPB) induces a systemic inflammatory response called 'post-pump syndrome'. As part of complex interaction between white cells and vascular endothelium, proinflammatory cytokines IL-6 IL-8 are phased immune that is also balanced by anti-inflammatory such as IL-10. We compared the influence heparin-coated circuits, steroids, aprotinin on these cytokines, looking for ways to reduce syndrome. Methods: 40 patients with coronary artery disease (CAD) undergoing...

To report the results of a two-center study endovascular abdominal aortic aneurysm (AAA) exclusion using polyester-covered nitinol stent-graft.Candidates were evaluated with arteriography and computed tomography. Criteria for therapy proximal neck > 10 mm in length < 25 diameter, no bilateral internal iliac artery involvement aneurysm, markedly tortuous common arteries (CIAs) or CIAs 7 superior mesenteric occlusive disease. Patients treated Mialhe Stentor Vanguard stent-grafts either tube...

R&D collaborations and the role of proximity. Regional Studies. This paper explores impact proximity measures on knowledge exchange measured by granted research development (R&D) collaboration projects in German NUTS-3 regions. The results are obtained from a spatial interaction model including eigenvector filters. Not only geographical but also other forms (technological, organizational institutional) have significant influence emergence collaborations. Furthermore, suggest interdependences...

In order to harmonizFranziska Hönige the supply and demand of green energy, new future-proof technologies are needed. Here, hydrogen plays a key role. Within current framework conditions, production is not yet economically viable. The use oxygen produced possible increase in efficiency associated with it mostly remain unconsidered. aim demonstrate that economic power-to-gas (PtG) project can be increased by using byproduct oxygen. this research project, water electrolyzer connected grid...

PURPOSE To compare the diagnostic accuracy of magnetic resonance imaging (MRI) and immunoscintigraphy (IS) for detection bone marrow infiltration in malignant lymphoma. PATIENTS AND METHODS In 32 patients with Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL), MRI axial skeleton whole-body IS using technetium-99m (99mTc)-labeled monoclonal antibodies were reviewed compared iliac crest biopsies. Criterion was a positive biopsy concordant results IS. RESULTS 16 (50%), MRI, IS, biopsies...

We report on the treatment of invasive aspergillosis with new triazole antimycotic agent itraconazole. All 11 patients suffered from pulmonary aspergillosis. Two also had cerebral aspergillosis; in one these paranasal sinuses were invaded. Underlying diseases acute lymphoblastic leukaemia (n = 3), myeloid 4); patient underwent allogeneic bone marrow transplantation before he developed another was transplanted after successful treatment, liver cirrhosis 1), lung infarction embolism chronic...

A 64-year-old male was admitted with suspected aortoduodenal fistula 16 years after transabdominal aortic reconstruction for aortoiliac occlusive disease. Computed tomography (CT) and angiography revealed an a suture-line aneurysm at the proximal anastomosis. Due to patient's poor general condition time of diagnosis, endoluminal stent-graft implantation chosen rather than conventional surgery. Successful placement stent graft without leakage contrast medium complete exclusion demonstrated by...
