[Transient patency loss of the internal carotid artery in a young patient].

Ischaemic stroke has been observed more rarely among young people in comparison to old adults. The causes of ischaemic stroke among young adults are numerous. One of them is occlusion of internal carotid artery (ICA). The aetiology of the occlusion is different from arteriosclerotic disorders. Within the last few years the authors have paid much attention to the fact that spontaneous dissection is not such a rare cause of ICA occlusion. In many cases (60-70%) of dissection recanalization and benign outcome occur. Angiography has been considered as a gold standard in establishing the diagnosis. We described a young, 16-year-old patient with ischaemic stroke. The cause occlusion of ICA, probably was dissection. The diagnosis was made by angiography MR. In our patient follow-up angiography MR demonstrated recanalisation. The outcome of the stroke was benign and hemiplegia reversed.
