Subjects will take extra strength acetaminophen (4g/day) for the three days prior to the embolization procedure.
1 gram acetaminophen 4 times a day with at least 6 hour intervals between doses for the 3 days prior to the embolization procedure.
Other Name: Tylenol
No Intervention: Observational - No Acetaminophen
Subjects will take no acetaminophen containing products prior to the embolization procedure.
- APAP-CYS Concentrations Over Time - Acetaminophen Group [ Time Frame: 14 days ]To describe the course of APAP-CYS concentrations following hepatic embolization in subjects who receive 4 grams/day of acetaminophen for three days prior to the procedure
- APAP-CYS Concentrations Over Time - Non-Acetaminophen Group [ Time Frame: 2 years ]To determine if subjects who report no exposure to acetaminophen prior to the procedure have detectable APAP-CYS concentrations
- Relationship between APAP-CYS and other biochemical markers of liver function [ Time Frame: 2 years ]To evaluate the relationship between APAP-CYS concentrations with aspartate aminotransferase (AST), alanine aminotransferase (ALT), and miRNA activity
