Hypersecretory Paraganglioma Presenting as Acute Aortic Dissection.

Abrupt, transient, and severe hypertension evoked by catecholamine-secreting tumors has the potential to manifest as acute aortic dissection. We report the successful, multidisciplinary management of an insidious, extra-adrenal, functional paraganglioma, suddenly presenting as acute aortic dissection. ().

Improved oxygenation with reduced recirculation during venovenous ECMO: comparison of two catheters.

Objectives: To determine whether the new double-lumen catheter made by OriGen Biomedical (Austin, TX) for venovenous (VV) extracorporeal membrane oxygenation (ECMO) would reduce recirculation and improve oxygenation during VV ECMO when compared with the Kendall double-lumen catheter (Kendall Healthcare Products, Mansfield, MA).

Design: Prospective intervention study.

Setting: The animal research laboratory at Children's National Medical Center, Washington, DC.
