Multicenter StudyTranscatheter closure of patent foramen ovale in patients with platypnea-orthodeoxia: results of a multicentric French registry.
Dyspnea and the decrease in arterial saturation in the upright position in elderly subjects is described as platypnea-orthodeoxia syndrome (POS). POS is secondary to the occurrence of an atrial right-to-left shunt through a patent foramen ovale (PFO). ⋯ Percutaneous occlusion of the foramen ovale is safe and gives excellent results thanks to continuing improvement in available devices. This technique enables some patients in an unstable condition to avoid a surgical closure.

Case ReportsA case of traumatic mesenteric bleeding controlled by only transcatheter arterial embolization.
We report a case of mesenteric hematoma following blunt abdominal trauma that was successfully treated with transcatheter arterial embolization (TAE) and did not require surgical repair. A 43-year-old man with blunt abdominal trauma caused in a factory accident was admitted with a stable general condition and laboratory data. On CT examination, a large mesenteric hematoma with extravasation of contrast media was observed. ⋯ After successful TAE using microcoils, the distal portion of the cecal branch was still preserved via collateral circulation. No abdominal symptoms have occurred during the 7 months following TAE. In mesenteric injury cases with limited intestinal damage, TAE may therefore be a reasonable alternative to emergent laparotomy.
