  • Hydrops Fetalis

    abnormal accumulation of serous fluid in two or more fetal compartments, such as skin; pleura; pericardium; placenta; peritoneum; amniotic fluid. general fetal edema may be of non-immunologic origin, or of immunologic origin as in the case of erythroblastosis fetalis.

  • Hydrops Fetalis

    a condition characterized by fluid accumulation in two or more anatomic compartments in the fetus.

  • Immune Hydrops Fetalis

    fluid accumulation in multiple fetal anatomic cavities attributable to a maternal immune response against fetal blood cell antigens.

  • Non-Immune Hydrops Fetalis

    fluid accumulation in multiple fetal anatomic cavities that is of non-immune origin.

  • Anasarca

    a condition that is characterized by the presence of generalized edema. causes include congestive heart failure, liver failure, renal failure, and severe malnutrition.

Patient EducationClinical

Edema

Edema means swelling caused by fluid in your body's tissues. It usually occurs in the feet, ankles and legs, but it can involve your entire body.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
