Prävention nach akutem Koronarsyndrom

2014

Das akute Koronarsyndrom hat eine erhohte Mortalitat auch im Verlauf nach erfolgreicher interventioneller Therapie. Entscheidend ist die Beurteilung, ob sich im Anschluss an das ACS eine Herzinsuffizienz entwickelt. In der Differenzierung des myokardialen Schadens als auch der Bestimmung des Verlustes an Funktion spielt die nichtinvasive Bildgebung eine besondere Bedeutung. Hinsichtlich der sekundaren Pravention richtet sich die nicht-medikamentose als auch medikamentose Therapie nach der myokardialen Funktion und dem Vorhandensein oder Fehlen einer Herzinsuffizienz. Ausdauerbelastung spielt bei den nicht-medikamentosen Masnahmen in der Rehabilitation je nach Schwere der Schadigung des Herz…

Die Erfassung symptomarmer traumatischer intracerebraler H�matome durch fr�hzeitige Angiographie

1964

Bei vielen gedeckten SchAdel-Hirn-Verletzungen ist der Heilungsverlauf im VerhAltnis zur Schwere des Anfangszustandes auffAllig verzogert. Diese Verzogerung kann darin begrundet sein, da\ neben der contusionellen SchAdigung des Gehirns noch eine mehr oder minder gro\e intracerebrale Blutung vorliegt. Solche FAlle sind aber nur dann zu erfassen, wenn alle schwereren SchAdelhirntraumen grundsAtzlich einer cerebralen Angiographie unterzogen werden. Ohne die angiographische Sicherung wird manches Zustandsbild als schwere Contusio angesehen werden, welches durch eine Hirnsubstanzblutung bedingt ist. Wie einer unserer FAlle zeigt, kann auch ein gro\eres intracerebrales HAmatom klinisch zunAchst v…

Transcatheter radiofrequency perforation and stent implantation for palliation of pulmonary atresia in a 3060-g infant

1995

In a 3060-g infant with fibromuscular pulmonary atresia an open right ventricular outflow tract was created by means of interventional cardiological methods. Following two inadvertent perforations without sequelae or clinical symptoms, radiofrequency perforation and subsequent balloon dilatation were successfully performed. The implantation of a Palmaz iliac stent led to a predictable communication between the right ventricle and pulmonary artery.

High Degree of Realism in Teaching Percutaneous Coronary Interventions by Combining a Virtual Reality Trainer With a Full Scale Patient Simulator

2008

The virtual reality coronary angiography simulator "CATHI" (Catheter Instruction System, Mannheim, Germany) simulates coronary arteries with implemented vessel lesions in virtual patients. Like similar systems the software model runs on common PC systems, which are linked to the mechanical device for manual training. We combined the advantages of this skill trainer with the near to reality assembly of a cardiac catheterization laboratory (Cath-lab) by connecting it to a full scale simulator (HPS, METI, Sarasota, FL). We present two methods of synchronizing the heartbeat between both simulation devices. Method A-the hardware solution-uses the electrocardiogram-synchronization signal of the H…

Computer-aided detection of cerebral microbleeds in susceptibility-weighted imaging.

2014

Susceptibility-weighted imaging (SWI) is recognized as the preferred MRI technique for visualizing cerebral vasculature and related pathologies such as cerebral microbleeds (CMBs). Manual identification of CMBs is time-consuming, has limited reliability and reproducibility, and is prone to misinterpretation. In this paper, a novel computer-aided microbleed detection technique based on machine learning is presented: First, spherical-like objects (potential CMB candidates) with their corresponding bounding boxes were detected using a novel multi-scale Laplacian of Gaussian technique. A set of robust 3-dimensional Radon- and Hessian-based shape descriptors within each bounding box were then ex…

Avoiding Complications in Aneurysm Ligation: Operative Tips and Tricks

2022

Preventing possible complications during brain aneurysm surgery is mandatory to ensure a better outcome for patients. Currently, it is possible to rely on some technologic innovations such as motor evoked potential, endoscope-assisted surgery, dye with indocyanine green, and video angiography capable of supporting the surgeon's work. The innovation process has mainly assisted the endovascular technique compared with surgery. The latter, apart from some new technical expedients, always requires anatomic knowledge and optimal technical preparation. A careful patient selection, adequate surgical exposure, use of microsurgical techniques in expert hands, and meticulous postoperative management …

Indocyanine Green Angiography in Congenital Hypertrophy of the Retinal Pigment Epithelium

2017

PURPOSE To report a case of congenital hypertrophy of the retinal pigment epithelium followed up for 7 years showing features not previously reported. METHODS A complete fundus examination including fluorescein angiography was performed at first examination and at follow-up. RESULTS The area of congenital hypertrophy of the retinal pigment epithelium presented morphologic changes, showing enlargement of the lesion on one side associated with partial regression on another side. In addition, the indocyanine green angiography findings revealed that this test was more useful than fluorescein angiography to delineate the real boundaries of the lesion and disclosed hypofluorescent areas inside th…
