Acute massive pulmonary embolism: use of a rotatable pigtail catheter for diagnosis and fragmentation therapy.
TL;DR: The modified pigtail catheter for angiographic documentation and mechanical fragmentation of pulmonary embolism was evaluated for its efficacy and safety and rapid partial recanalization was achieved with relative ease of instrumentation.

New optional IVC filter for percutaneous retrieval--in vitro evaluation of embolus capturing efficiency.
Rolf W. Günther,Jörg Neuerburg,Anne Mossdorf,J Pfeffer,A R Høj,A Mølgaard-Nielsen,Arno Bücker,Thomas Schmitz-Rode +7 more
TL;DR: In-vitro evaluation of a new caval filter developed for delayed percutaneous retrieval in comparison to the Gunther Tulip filter showed similar in-Vitro capture properties as the gunther Tulips and deserves further in-vivo testing.

Mechanical delivery of aerosolized gadolinium-DTPA for pulmonary ventilation assessment in MR imaging.
Patrick Haage,Gerhard Adam,Süleyman Karaagac,J Pfeffer,Arndt Glowinski,S. Döhmen,Rolf W. Günther +6 more
TL;DR: The results of this refined technique substantiate the potential of Gd-based ventilation MR imaging by improving aerosol distribution and shortening the nebulization duration in the healthy lung.

Fragmentation of pulmonary emboli: in vivo experimental evaluation of two high-speed rotating catheters.
Thomas Schmitz-Rode,Gerhard Adam,Markus Kilbinger,J Pfeffer,Stefan Biesterfeld,Rolf W. Günther +5 more
TL;DR: Embolus fragmentation led to a hemodynamic improvement and the impeller catheter was less traumatic compared with the thrombolizer, which was technically insufficient.

Introduction of a dedicated circulation phantom for comprehensive in vitro analysis of intravascular contrast material application.
Florian F. Behrendt,Philipp Bruners,John F. Kalafut,Andreas H. Mahnken,Sebastian Keil,Cedric Plumhans,Marco Das,Sven Stanzel,Joachim E. Wildberger,J Pfeffer,Rolf W. Günther,Georg Mühlenbruch +11 more
TL;DR: A flow phantom with physiologic circulation parameters for measurement of contrast enhancement is developed and is suitable for further evaluation of CM injection protocols for pulmonary and aortic enhancement.
