Embolization of hemorrhage from a ruptured hepatocellular carcinoma via the false lumen of an aortic dissection using transradial access

BACKGROUND AND AIMS Transcatheter arterial embolization (TAE) has been repeatedly shown as an effective method of controlling acute hemorrhage. Arterial access for TAE in the emergent setting is typically trans-femoral, though other routes are routinely used. The presence of abnormal vasculature such as an aortic dissection increases the difficulty of TAE. CASE REPORT This report details a case of acute hemorrhage likely from a ruptured hepatocellular carcinoma in which the celiac artery originated from the false lumen of a type B aortic dissection. CONCLUSION The false lumen was catheterized via left radial artery access and the bleeding hepatic arterial branch was successfully embolized.
