Abstract
Penetrating neck injury
causing internal carotid artery (ICA) transection is nearly always
fatal. The novel use of Onyx Liquid
Embolic System (Onyx LES) for rapid
hemostasis of a traumatic cervical ICA transection is reported. A
patient with a gunshot
wound to the face and neck underwent
emergent catheter angiography which revealed contrast extravasation from
the right cervical
ICA consistent with traumatic
transection. The ipsilateral cerebral hemisphere showed collateral blood
supply from the posterior
communicating artery, and ipsilateral
external carotid artery anastomoses of the facial, ethmoidal and
ophthalmic arteries.
Rapid endovascular repair of the
transected cervical ICA was performed using Onyx LES. Onyx34 was
injected at a rapid rate
of 1 ml/min into the right ICA.
Injection was continued until cast formation completely occluded the
proximal cervical ICA
but preserved the external carotid
artery. This method very rapidly controlled bleeding and should be
considered in these
cases.
