PURPOSE To evaluate the pattern of recanalization and specific inflammatory reaction after superselective embolization with four commercially available spherical embolic agents of different sizes in the mini pig kidney model. MATERIALS AND METHODS In 40 mini pigs, the lower poles of both kidneys were superselectively embolized with Embozene, Embosphere,(More)
PURPOSE To determine the arterial distribution pattern of the embolic agent Embozene within the porcine kidney and compare it with those of other spherical embolic agents. MATERIALS AND METHODS Embozene, Embosphere, Bead Block, and Contour SE in size classes of 100-300 microm, 500-700 microm, and 700-900 microm and Embozene and Embosphere in the size(More)
To evaluate safety and efficacy of uterine artery embolization using narrow-size-range polyphosphazene-coated hydrogel microspheres (Embozene, CeloNova Biosciences, Newnan, GA). Between May 2006 and September 2008, a total of 121 consecutive patients (mean ± SD age 42.1 ± 5.4 years, range 30.5–51.5 years) were enrolled onto this single-center study. The(More)
PURPOSE To evaluate whether virtual non-enhanced imaging (VNI) is effective to replace true non-enhanced imaging (TNI) applying iodine removal in intravenous dual-energy CT-cholangiography. MATERIALS AND METHODS From April 2009 until February 2010, fifteen potential donors for living-related liver transplantation (mean age 37.6±10.8 years) were included.(More)
Die Vereinbarkeit von Familie und Beruf ist in medizinischen Fachberufen mit Schichtdiensten und Überstunden ein schwieriges Unterfangen. Da Frauen im ärztlichen Bereich zunehmend die Mehrheit stellen, werden insbesondere angesichts des manifesten Ärztemangels bei der Auswahl der Arbeitsstelle sozial-familiäre Gesichtspunkte eine größere Rolle spielen.

PURPOSE We evaluated the technical success and clinical efficacy of stent-graft implantation for the emergency management of acute hepatic artery bleeding. METHODS Between January 2010 and July 2013, 24 patients with hemorrhage from the hepatic artery were scheduled for emergency implantation of balloon expandable stent-grafts. The primary study endpoints(More)
The objective of this study was to evaluate inflammatory response and recanalization after embolization with a new spherical embolic agent based on a core and shell design with a hydrogel core of polymethylmethacrylate (PMMA) and a Polyzene-F nanoscale coating in a porcine kidney model. Thirty-six minipigs were enrolled for superselective renal(More)
PURPOSE To quantify the extent of tissue shrinkage and dehydration caused by microwave (MW) ablation in kidneys for estimation of effective coagulation volume. MATERIALS AND METHODS MW ablations were carried out in ex vivo porcine kidneys. Six study groups were defined: groups 1A, 2A, and 3A for MW ablation (90 W for 5 min, 7.5 min, or 10 min), and groups(More)
PURPOSE To evaluate the influence of deployed energy on extent and shape of microwave (MW)-induced coagulation in porcine livers applying 5-minute protocols. MATERIALS AND METHODS MW ablations (n = 25) were performed in ex vivo porcine livers (n = 8). Ablation time was 5 minutes. Five study groups were defined, each with different power output: I, 20 W (n(More)
PURPOSE Purpose of this study was to evaluate the frequency, probability, and factors associated with expulsion of submucosal fibroids after uterine artery embolization (UAE) in addition to the technical and clinical results at 1-year follow-up. MATERIALS AND METHODS We determined the preinterventional volume of each dominant submucosal fibroid using the(More)
