Direct puncture of large arteriovenous malformations in head and neck for embolisation and subsequent reconstructive surgery.
Five patients with large arteriovenous malformations (AVM) of the head and neck, which were too large or inconveniently placed for operation alone, were treated by embolisation after direct puncture; two of them were subsequently operated upon. They all recovered without complications. Embolisation of the nidus and subsequent operation is a good alternative for the treatment of large AVM. Ligating the supplying arteries is not a treatment. If the arterial routes to the nidus have previously been closed by ligatures selective catheterisation is impossible, though direct puncture of the nidus is a possibility. The nidus of the AVM can then be obliterated by embolisation either as a treatment, or as a preoperative procedure.
