Large 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.
A 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.
To 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.
大型动静脉畸形通常先通过血管内栓塞治疗，然后进行手术切除。我们描述了一种新型液体栓塞剂（LEA）——沉淀型疏水性可注射液体（PHIL）的使用及其相对于现有液体栓塞剂的优势。
一名60岁男性，右耳后动静脉畸形逐渐增大。他在栓塞术后第1天接受了PHIL连续血管内栓塞及后续手术切除。
据我们所知，这是首例报道将PHIL用于大型颅外头颈部动静脉畸形术前栓塞的病例。它能很好地穿透小口径血管，减少成像时的眩光伪影，并减少皮肤色素沉着，使其成为现有液体栓塞剂的有力替代物。
