Imaging of Patients with Complex Hemodialysis Arterio-Venous Fistulas using Time-Resolved Dynamic CT Angiography: Comparison with Duplex Ultrasound.

To evaluate the feasibility and potential on therapy management of time-resolved dynamic computed tomography angiography (dCTA) in patients with forearm arterio-venous fistula (AVF)/arterio-venous grafts (AVG). Thirty-five patients with complex failing forearm AVF/AVGs were examined with ultrasound and a dCTA protocol. Diagnosis and therapy management was evaluated versus duplex ultrasound (DUS) in three different readouts: 1.

Pump-assisted enteral nutrition can prevent aspiration in bedridden percutaneous endoscopic gastrostomy patients.

Background: Vomiting, aspiration, and pneumonia are serious side effects in enteral feeding via percutaneous endoscopic gastrostomy (PEG), which often leads to hospitalization. To this day, it has not been proven whether pump-assisted (PA) or gravity-controlled application is the safer method for long-term feeding via PEG in bedridden patients.

Methods: This study was conducted as a prospective, randomized crossover study.

Pump-assisted versus gravity-controlled enteral nutrition in long-term percutaneous endoscopic gastrostomy patients: a prospective controlled trial.

Background: Vomiting, aspiration, flatulence, and diarrhea are well-known negative side effects of enteral nutrition through percutaneous endoscopic gastrostomy (PEG). However, it is not yet clarified if pump-assisted (PA) or gravity-controlled (GC) application is the more comfortable and safe choice for long-term nutrition through PEG.

Methods: This was a prospective, randomized, crossover study.
