Radiological findings in ischaemic cholangiopathy.

Ischaemic cholangiopathy occurs as a consequence of deficient arterial blood flow to the bile duct wall. Bile duct ischaemia can lead to full-thickness necrosis, bile leakage, biloma formation, and sepsis. It is an important cause of graft failure post-orthotopic liver transplantation. In the native liver, the causes of biliary ischaemia are diverse and include vasculitis or a complication of endovascular procedures. The present review describes the pathology and radiological findings of ischaemic cholangiopathy and outlines the role of interventional radiology in its management.

Application of cone-beam computed tomography angiography in a uterine fibroid embolization procedure: A case report.

One of the main causes of failure in uterine fibroid embolization procedures is incomplete infarction of the fibroid due to alternate vascular supply to the fibroid which was not identified by the operator. Cone-beam computed tomography angiography was used in this case to avoid nontarget embolization via a uterine artery, as well as identify incomplete embolization of the fibroid. This prompted a search for variant vascular supply to the fibroid, which was found to be originating from the right ovarian artery. Therefore, the use of cone-beam computed tomography angiography led to a successful outcome, which otherwise may not have been achieved.
