Introduction. Internal carotid artery (ICA) kinking is a pathological
malformation with angulation of the vessel’s axis of 90° or less. It is known
that kinking causes the reduction of flow within the vessel that may be
exacerbated by progressive head rotation up to the point that causes complete
cessation of flow. In this article, we report on the case of acute reversible
ischaemic deficit induced by internal carotid artery kinking and immediate
neurological recovery following surgical reconstruction. Case Outline. A
64-year-old woman was admitted to Vascular Surgery Clinic due to severe
dizziness, fainting and walking instability, suddenly arising a few days
prior to admission. Two years before, the left ICA reconstruction was done
for kinking, after which there was no cerebral ischaemia symptoms. Symptoms
have been present perpetually, enhanced when resting and with head movement.
CT angiography (MSCT) showed haemodynamic significant right ICA kinking. The
left ICA postoperative finding was regular. Computerized tomography (CT) of
the endocranium was done and no novel lessions were verified than those seen
two years earlier. Resection, shortening and reimplantation of the right ICA
were performed. A few hours following surgical reconstruction, there was no
cerebral ischaemia symptoms, neither when resting nor with head movement.
On the third postoperative day, the patient was discharged for home
treatment. Conclusion. Surgical repair for symptomatic ICA kinking
contributes to cerebral ischaemia symptoms reduction, improves cerebral
perfusion and significantly prevents carotid thrombosis and stroke. In this
paper, we have seen that in case of acute cerebral ischaemia symptoms and ICA
kinking, surgical ICA treatment appears to be justified.
