Vertebral artery dissection (VAD) is a rare cause of young age stroke. This risky condition can be caused by even minor head or neck trauma. None of the previous studies has reported cough-related intracranial vertebral arterial dissection in Korea. We present two cases of cerebral infarctions from VAD induced by severe coughing. We should be alert to clinical manifestations of VAD to make proper diagnosis and to recognize coughing as a potential cause of VAD.

When a tear occurs in one of the major cervicocerebral arteries and allows blood to enter the wall of the artery and split its layers, the result is either stenosis or aneurysmal dilatation of the vessel. Vertebral artery dissection (VAD) is an infrequent occurrence but is a leading cause of stroke in young and otherwise healthy patients. This article discusses recent developments in understanding of the epidemiology and pathogenesis of VAD and the various clinical manifestations, methods of diagnosis, and approaches to treatment.

The equipment and techniques associated with magnetic resonance imaging (MRI) have rapidly evolved. The development of 3.0 Tesla MRI has enabled high-resolution imaging of the intracranial vessel wall. High-resolution MRI (HRMRI) can yield excellent visualization of both the arterial wall and lumen, thus facilitating the detection of the primary and secondary features of intracranial arterial dissection. In the present report, we describe the manner in which HRMRI affected our endovascular treatment planning strategy in 2 cases with unruptured intracranial vertebral artery dissection aneurysm. HRMRI provides further information about the vessel wall and the lumen of the unruptured intracranial vertebral artery dissecting aneurysm, which was treated by an endovascular approach in the 2 current cases.

The optimal treatment and appropriate follow-up period for an unruptured vertebral artery (VA) and/or posterior inferior cerebellar artery (PICA) dissection have not been established. Decisions regarding treatment of these vascular lesions are usually based on the manifesting symptoms and changes in radiologic findings during the follow-up period. We experienced a patient who had a simultaneous unruptured VA dissection and a contralateral PICA dissecting aneurysm. We did not find such a case in other literature.

We report a case of spontaneous bilateral intracranial vertebral artery dissecting aneurysms with subarachnoid hemorrhage. One dissecting lesion was treated with a coronary balloon-mounted stent (BMS) technique; however, due to differences in access route tortuosity, the other lesion was treated with a self-expandable stent (SES) technique. After 2 months, the angiographic outcome showed complete healing of the dissected segment on the side that was treated with BMS; in contrast, the dissection lesion appeared to be re-growing on the side that was treated with SES. Complete treatment of the aggravated lesion was achieved by additional deployment of BMSs. Therefore, we have provided a discussion of the possible reasons for this difference in outcome according to the stent type.
