Auf schwankendem Grund. Dekadenz und Tod im Venedig der Moderne

Anlass des Bandes ist das Centenarium von Thomas Manns Novelle "Der Tod in Venedig" (1912), in der Gustav von Aschenbach als ein der historischen Wissenschaft verpflichteter Schriftsteller in unsicheres Terrain jenseits rationaler Begrifflichkeit gerät, ins Sehnsuchtsland der Liebe und des Schönen, und schließlich in einen Grenzbereich, in dem alles Gestaltete ins Gestaltlose und schließlich in den Tod übergeht. Venedig um 1900, die auf Wasser gebaute, einstige Seerepublik in politischer Dekadenz ist nicht zufällig dafür topisch, und Aschenbach mit seinen ethischen, ästhetischen und epistemologischen Erschütterungen in Venedig nicht allein. Venedig prägte seine eigene Moderne aus und wurde als physisch erlebter wie imaginier­ter Ort für Dichter, Maler und Musiker zum Spiegel der Krisenerfahrungen um 1900. Anders gesagt: Die Stadt fungierte als Seismograph, mit dem sich der Verlust metaphysischer Gewissheiten, der Verlust des Vertrauens in die Evidenz des Wissens, in die Einheit der Person und der Zuverlässigkeit der Sprache aufzeichnen ließ. Die Unbestimmtheit, der Kontrollverlust, die der Lagu­nenstadt eigene Bewegung ›auf schwankendem Grund‹ wird bei Thomas Mann und seinen Zeitgenossen zum Motor der Kreativität

2D-Perfusion Angiography Using Carbon Dioxide (CO2): A Feasible Tool to Monitor Immediate Treatment Response to Endovascular Therapy of Peripheral Arterial Disease?

Purpose!#!Patients with peripheral arterial disease (PAD) or critical limb ischemia (CLI) require revascularization. Traditionally, endovascular therapy (EVT) is performed with iodinated contrast agent (ICM), which can provoke potential deterioration in renal function. CO2 is a safe negative contrast agent to guide vascular procedures, but interpretation of CO2 angiography is challenging. Changes in blood flow following iodine-aided EVT are assessable with 2D-perfusion angiography (2D-PA). The aim of this study was to evaluate 2D-PA as a tool to monitor blood flow changes during CO!##!Material and methods!#!2D-PA was performed before and after ten EVTs (nine stents; one endoprosthesis; 10/2012-02/2020) in nine patients (six men; 65 ± 10y) with Fontaine stage IIb (n = 8) and IV (n = 1). A reference ROI (ROI!##!Results!#!2D-PA was technically feasible in all cases. A significant increase of 82% in PD!##!Conclusion!#!The presented 2D-PA technique facilitates the assessment of arterial flow in CO2-aided EVTs and has the potential to simplify the assessment of immediate treatment response

Transjugular intrahepatic portosystemic shunt placement: portal vein puncture guided by 3D/2D image registration of contrast-enhanced multi-detector computed tomography and fluoroscopy

Background!#!To assess the technical feasibility, success rate, puncture complications and procedural characteristics of transjugular intrahepatic portosystemic shunt (TIPS) placement using a three-dimensional vascular map (3D-VM) overlay based on image registration of pre-procedural contrast-enhanced (CE) multi-detector computed tomography (MDCT) for portal vein puncture guidance.!##!Materials and methods!#!Overall, 27 consecutive patients (59 ± 9 years, 18male) with portal hypertension undergoing elective TIPS procedure were included. TIPS was guided by CE-MDCT overlay after image registration based on fluoroscopic images. A 3D-VM of the hepatic veins and the portal vein was created based on the pre-procedural CE-MDCT and superimposed on fluoroscopy in real-time. Procedural characteristics as well as hepatic vein catheterization time (HVCT), puncture time (PT), overall procedural time (OPT), fluoroscopy time (FT) and the dose area product (DAP) were evaluated. Thereafter, HVCT, PT, OPT and FT using 3D-VM (61 ± 9 years, 14male) were compared to a previous using classical fluoroscopic guidance (53 ± 9 years, 21male) for two interventional radiologist with less than 3 years of experience in TIPS placement.!##!Results!#!All TIPS procedure using of 3D/2D image registered 3D-VM were successful with a significant reduction of the PSG (p < 0.0001). No clinical significant complication occurred. HVCT was 14 ± 11 min, PT was 14 ± 6 min, OPT was 64 ± 29 min, FT was 21 ± 12 min and DAP was 107.48 ± 93.84 Gy cm!##!Conclusion!#!TIPS placement applying registration-based CE-MDCT vessel information for puncture guidance is feasible and safe. It has the potential to improve hepatic vein catherization, portal vein puncture and radiation exposure
