[Spontaneous and heparin-induced recanalization of the completely occluded internal carotid artery--a neglected phenomenon? 2 case reports and review of the literature].
This report presents two cases of totally occluded internal carotid arteries, verified by angiography. In both cases the vessel was recanalised under heparinisation. This was first detected by duplex carotid sonography. Angiographic follow-up showed a high-grade stenosis at the origin of the internal carotid artery. Both female patients were then operated successfully. It is important to consider the possibility of spontaneous recanalisation of an occluded internal carotid artery because there are clear indications for operative treatment in such a case. In case of total occlusion, as a rule no operative treatment is possible.
