Novel use of precipitating hydrophobic injectable liquid (PHIL) in pre-operative angioembolisation of a large posterior auricular arteriovenous malformation

BACKGROUNDLarge arteriovenous malformations are often managed via endovascular embolisation followed by surgical resection. We describe the use of a new liquid embolic agent (LEA) - precipitating hydrophobic injectable liquid (PHIL) and its advantages over existing LEAs. CASEA 60-year-old male prese...

description BACKGROUNDLarge arteriovenous malformations are often managed via endovascular embolisation followed by surgical resection. We describe the use of a new liquid embolic agent (LEA) - precipitating hydrophobic injectable liquid (PHIL) and its advantages over existing LEAs. CASEA 60-year-old male presented with a progressively enlarging right post-auricular arteriovenous malformation. He underwent successive angioembolisation with PHIL and subsequent surgical resection on post-embolisation day 1. CONCLUSIONTo our knowledge, this is the first reported case of PHIL being used in pre-operative embolization of a large extra-cranial head and neck AVM. Its excellent penetration into small calibre vessels, decreased glare artefact on imaging and decreased skin pigmentation render it a compelling alternative to existing LEAs.
