the foley really wasnt working very well
going from one vertebral to the other is relatively easy and has been reported several times over the past twenty years. I did one and it took less than ten minutes from decision to completion. but going through the middle of the circle of willis is another thing altogether and is one of the scariest scenarios i have thought about my entire career with, fortunately, no opportunity to try it. 

But this case seemed like it was one where this strategy would be a solution to this patient's bleeding. 

That is why i called this my best case. a difficult problem, trying circumstances, few alternatives and a successful hemostasis

I used a 2.6 French microcatheter that I was able to get across from the left vertebral into the basilar, through the left posterior communicating artery into the distal segment of the internal carotid artery. Getting down below the skull base and introduction of a couple of coils ended this bleeding instantaneously. (see attached)
36 hours later he is conscious and alert with left arm and leg weakness. He is still intubated so it is difficult to assess thought, speech, etc.

distal carotid retrograde bleeding has never before occured?in my experience of?about 40 ICA endovascular treatments. Not exposing the transected carotid artery probably contributes to early thrombosis of the distal vessel. I guess the hole in the side of his neck and ear was a ready access to continued bleeding. 

A colleague of mine suggested trying to reenter the distal side before embolization but i really didnt expect distal bleeding. I still wonder about the risks of distal thromboembolization during that manipulation. 

I think that Norm's solution is a good one when one has experience and the injury is not too high in the neck near the skull base. In this case it would likely have been a difficult proposition because of four proximal bleeders and a fairly distant bleeding distal ICA. 

I recall a seasoned vascular surgeon with trauma experience trying to repair a laceration of the ICA as high as this one. when the injury fell apart, he was subjected to very significant blood loss coming from the distal side of the vessel. When he tried to clamp the distal vessel, it retracted into the carotid canal and he could not ligate. eventually he did as norm did and used bone wax to plug the carotid canal although the patient required about 15 units of blood before this was accomplished.

what was your suggestion if his circle of willis was not intact?

Exactly what I asked about / suggested earlier - distal end backbleeding
- leave the Foley catheter inflated for 48 hours and try again. It
should clot up. Otherwise move to OR and go and ligate the distal end.
Obviously there is "adequate" collateral flow!

If you are really good (like I know you are) you could go through the
circle of Willis with Micro-catherters and embolise the ICA from inside
the brain (seen it done once in Tygerberg - crossover from one vertebral
to the other to coil a vertebral AV fistula. Takes a bit of time though.

What is his Lactate and temp / pH at this point and how much blood has
he lost?

I decided that an attempt at stent graft of the external carotid artery
had merit in order to maintain the ophthalmic artery collateral and
because this would have treated the occipital, posterior auricular and
external carotid injuries simultaneously even if it occluded. I thought
that the graft had low likelihood of success because of the preexisting
post traumatic vasospasm and the small size of the vessel, but i didnt
think it would hurt to try.. 

A 5mm? diameter 22mm Atrium stent graft was placed over the injured
segment of the ECA and the orifices of both branches. It occluded within
minutes. 

The proximal ICA occlusion was secured with three gianturco
 coils. I
chose NOT to try to go through the clotted ICA to the other side?of?this
injury for fear of dislodging and embolizing clot into the brain.? 

There was still bleeding from the wound but when the balloon was
deflated, there was torrential bleeding. We intermittently let down the
balloon and repeated the angiography of the carotid and remaining
external carotid branches without seeing any extravasation.? So we
repeated angiography of all remaining three cerebral vessels. The left
vertebral angiogram is attached.

I have seen the second set of images.    I would also  consider
DEFLATING the 
tamponading balloon for a few seconds in order to obtain  a view.   It
may be 
that the internal carotid artery is occluded ONLY  by the occluding
balloon.

sal-  good save!.........is the patient awake? Any lateralizing signs?
I agree  with Norm. Based on this angio view the injury can be approach
thru 
formal  sternocleidomastoid approach........I favor repair before 
ligation........  although looks like the ophthalmic artery collateral
is open 
like Dr 
Mattox  well mention 
Good case
