We present the case of a man in his thirties who had attended the emergency department with complaint of a distressing headache and associated intermittent facial droop with occasional slurred speech. The patient’s symptoms were bizarre in their nature as they were random, not sustained and he had long intervals when he was asymptomatic and was his normal self. During the course of admission his symptoms evolved resulting in neurological deficits which were more sustained, prompting the need for further imaging beyond the initial plain CT brain which showed no abnormality. This led to the diagnosis of vertebral artery dissection (VAD) complicated with an ischaemic stroke in the posterior inferior cerebellar artery distribution (PICA) on MRI/MRA. Dual anti-platelet treatment was commenced with the patient attaining gradual symptomatic improvement prior to discharge. He has reported some degree of neurological sequelae which he described as intermittent poor coordination on follow up visit in clinic after discharge.

Vertebral artery dissection (VAD) is an important cause of ischemic stroke and subarachnoid hemorrhage (SAH). Dissections presenting with ischemia rarely cause SAH after more than a few hours, especially without radiographic evidence of pseudoaneurysm. We successfully treated a patient for persistent vessel injury presenting with SAH 7 years after presenting with extracranial subocclusive dissection of the right vertebral artery and an associated right posterior inferior cerebellar artery stroke. This is one of only three reported cases of delayed SAH occurring more than 2 weeks after an initial ischemic presentation of a VAD, and the only one without radiographic evidence of pseudoaneurysm at standard follow-up duration.

Abstract BACKGROUND The treatment of intracranial vertebral artery dissection (VAD) can be challenging. OBJECTIVE To evaluate the clinical presentation, endovascular treatment techniques, and prognostic outcome of patients diagnosed with intracranial VAD at our institution. METHODS A retrospective analysis of 35 patients who were diagnosed with VAD at our institution over 17-yr period (2001-2017) is presented. A total of 27 patients with a total of 30 affected arteries underwent endovascular treatment, and their outcome was evaluated. RESULTS Of the 35 total patients with VAD, 15 presented with headache, 12 with focal neurological deficits, 2 with neck pain, 2 with dizziness, 1 with syncope, and 3 after trauma. Of the 30 dissected arteries, 18 were treated with deconstruction and 12 were treated with stent reconstruction. Treatment method was determined by the dominance of the affected artery and location relative to the ipsilateral posterior inferior cerebellar artery (PICA) and the basilar artery. Deconstructive techniques were utilized in all cases of hypoplastic artery dissection and the majority of codominant artery dissections, whereas reconstruction was performed on the majority of dominant artery dissections. Rupture did not impact treatment technique. Four patients demonstrated post-treatment infarcts, and another 1 patient died because of intraparenchymal bleed. The remaining 22 patients demonstrated favorable clinical outcome. None of the patients developed recanalization or needed retreatment till the last follow-up. CONCLUSION This study suggests that endovascular treatment of intracranial VAD with deconstruction or stent reconstruction based on the patients anatomy, particularly vessel dominance and location with respect to PICA, is feasible and effective though the revascularization procedures still has its role in selected cases.
