There are very few reports describing the presence of a stump embolism after vertebral artery occlusion. We describe three patients who presented with posterior circulation ischemic strokes after vertebral artery occlusion. These patients were successfully treated with anticoagulation therapy without surgical or endovascular treatment.

Injury to spinal segmental arteries may potentially occur during spinal surgery, particularly during anterior or minimally invasive approaches. Use of a noninvasive radiologic tool to evaluate these arteries before surgery may reduce this risk. We performed spinal CT angiography and reconstructed 3D images of segmental arteries in 41 patients. We ...

To report clinical outcomes of lower cranial nerve palsy (LCNP) caused by vertebral artery (VA) aneurysms. Seventy-two patients with VA aneurysms, who were treated endovascularly between 2001 and 2008, were retrospectively studied to identify patients presenting LCNP without hemorrhage. LCNP occurred in 12 patients (16·7%) initially caused by VA aneurysms: ...

OBJECTIVE: Atherosclerotic stenosis or obstruction of the innominate artery is rare. Traditional surgical management is a technically demanding intervention with acceptable, but not negligible, rates of morbidity and mortality. Endovascular approaches to supraaortic lesions have been successful and are now the preferred treatment for stenoses of the brachiocephalic vessels. The ...

Multiple symptomatic vertebral artery (VA) loops are rare and their management is challenging. A 55-year-old man presented with a 5-year history of frequent episodes of presyncope and mild left C5 radiculopathy that was exacerbated by flexion or extension of his neck. Examination revealed complex left VA loops at C2/3 and ...

BACKGROUND: The endovascular treatment of intracranial aneurysms can be hampered by the tortuosity of extracranial vessels. Percutaneous or surgical vessel puncture can resolve the problem of inaccessibility. OBJECTIVE: We describe rerouting of a kinked vertebral artery (VA) to restore transfemoral endovascular access to an aneurysm. CASE REPORT: A 63-year-old woman ...

Craniovertebral anomalies are rare causes of vertebral artery dissection. Therefore, appropriate evaluation is necessary in vertebrobasilar strokes, specially in the young. This is particularly true for patients with vertebral stroke without risk factors. Here we report a 24-year-old male presenting with posterior circulation infarcts. The patient had no obvious vascular ...

The hypoglossal artery arises as a branch of the internal carotid artery and traverses the hypoglossal canal. However, the hypoglossal artery arising from the external carotid artery (ECA) and connecting directly with the posterior inferior cerebellar artery (PICA), instead of the basilar artery or the vertebral artery, is very rare. ...
