Controlled Clinical TrialPostpartum hemorrhage from extravasation or pseudoaneurysm: efficacy of transcatheter arterial embolization using N-butyl cyanoacrylate and comparison with gelatin sponge particle.
To evaluate the safety and effectiveness of transcatheter arterial embolization (TAE) using N-butyl cyanoacrylate (NBCA) for the treatment of active postpartum hemorrhage (PPH) and compare the efficacy of NBCA with gelatin sponge particles. ⋯ TAE using NBCA as the primary embolic agent is an effective method for treating PPH with extravasation or pseudoaneurysm; NBCA is comparable to gelatin sponge particles. TAE using NBCA seems to fill pseudoaneurysms and make devascularization more effective than using gelatin sponge.

Comparative StudyComparison of symmetric hemodialysis catheters using computational fluid dynamics.
Symmetric-tip dialysis catheters have become alternative devices because of low access recirculation and ease of tip positioning. Flow characteristics of three symmetric catheters were compared based on computational fluid dynamics (CFD) as they relate to catheter function. ⋯ The VectorFlow catheter produced less shear-induced platelet activation than the Palindrome catheter and less flow separation than the Palindrome and GlidePath catheters irrespective of line configuration. These findings have potential implications for differences in thrombogenic risk during clinical performance of these catheters.
