Extravasation is the leakage of intravenously IV infused, and potentially damaging, medications into the extravascular tissue around the site of infusion. The leakage can occur through brittle veins in the elderly, through previous venipuncture access, or through direct leakage from wrongly positioned venous access devices. When the leakage is not of harmful consequence it is known as infiltration. Extravasation of medication during intravenous therapy is an adverse event related to therapy that, depending on the medication, amount of exposure, and location, can potentially cause serious injury and permanent harm, such as tissue necrosis. Milder consequences of extravasation include irritation, characterized by symptoms of pain and inflammation, with the clinical signs of warmth, erythema, or tenderness.

Background and purpose: Hematomas that enlarge following presentation with primary intracerebral hemorrhage ICH are associated with increased mortality, but the mechanisms of hematoma enlargement are poorly understood. We interpreted the presence of contrast extravasation into the hematoma after CT angiography CTA as evidence of ongoing hemorrhage and sought to identify the clinical significance of contrast extravasation as well as factors associated with the risk of extravasation. Methods: We reviewed the clinical records and radiographic studies of all patients with intracranial hemorrhage undergoing CTA from to Only patients with primary ICH were included in this study. Univariate and multivariate logistic regression analyses were performed to determine the associations between clinical and radiological variables and the risk of hospital death or contrast extravasation. Results: Data were available for patients.

This image shows an early radiograph from a normal HSG. The white arrowhead is pointing towards the uterus, which is filled with contrast the radiopaque material , and is normal in shape. The white arrows are pointing towards the right and left fallopian tubes which are both beginning to fill with contrast.
Yaklic , Wright State University Follow. Unrecognized vaginal intubation during the barium enema procedure with subsequent balloon inflation and contrast instillation is a potentially fatal complication of an otherwise common and routine procedure. The patient was admitted for surgical repair of the vaginal laceration and monitoring for chemical peritonitis; and was managed without exploratory laparotomy.
