[Role of surgery in the treatment of dissections of the extracranial internal carotid artery. Apropos of a case, review of the literature].

The authors report about one operated case of spontaneous dissection of the extracranial internal carotid artery close to the bifurcation. The persistence of a floating thrombus in a 60% stenosis after a six-week treatment with heparin led to establishing the indication for surgery. The surgical indication remains exceptional, considering the natural history of dissections and the frequency of repatency of the arterial lumen. This type of surgery is mainly for sequellae such as stenosis, thrombi or saccular aneurysms, whose emboligenic potential leads to operating (exeresis and graft on the internal carotid artery) if the anatomical location of the lesion makes it possible.
