[Spontaneous dissection of the subclavian artery and its branches].
A 51-year-old woman suffering from vertigo presented to our cerebrovascular laboratory. MRI revealed a right-sided cerebellar infarction. On ultrasound examination, we found a dissection with wall hematoma of the right subclavian artery extending to the first segment of the vertebral artery and to the thyrocervical trunc, as well as a dissection of the left vertebral artery in the cranio-cervical junction. On follow-up evaluation, all stenoses resulting from dissection were recanalized within 2 months and findings of wall hematoma disappeared completely within 7 months. There was no evidence of a traumatic or iatrogenic cause of dissection; an aortic dissection was excluded by MRI. So we diagnosed a spontaneous dissection of the subclavian artery--an extremely rare but apparently existing vascular condition.
