Vertebroplasty consists of percutaneous injection of acrylic cement--polymethylmethacrylate (PMMA)--into a partially collapsed vertebral body in order to obtain pain relief and augment mechanical stability of the vertebral body. Although vertebroplasty is an efficient treatment it is not free of complications. Our present case report describes a woman with pulmonary polymethylmethacrylate ...

Spontaneous vertebral artery dissection is a condition that can have lethal consequences. The condition should be considered in young male patients who present with a stroke. At presentation, headaches, cerebral ischaemic episodes and oculosympathetic paresis are the most commonly encountered manifestations. The diagnosis is confirmed with angiography. Here, we present ...

When diagnosing and treating patients with acute vertigo, the clinician must differentiate brain lesions from benign peripheral disorders. We here report a rare case of acute vertigo caused by intracranial vertebral artery dissection mimicking peripheral disease. A 67-year-old man presented with spontaneous nystagmus and moderate ataxia preceded by neck pain. ...

OBJECTIVE: We performed a systematic microanatomical study of the occipital artery (OA) and its branches to describe the course, diameter, and branches of this vessel as well as the presence and pattern of anastomotic channels between the OA and the vertebral artery. METHODS: Twelve occipital arteries (6 adult cadaveric heads ...

BACKGROUND: Intracranial arteries in the subarachnoid space may compress the brain parenchyma and cranial nerves. Most arterial compressive lesions have been attributed to dolichoectasia in the vertebral-basilar system, and prior reports have concentrated on the pressure effects of basilar artery ectasia. Much less is known about vertebral artery compression of ...

Two patients developed de novo vertebral artery dissecting aneurysm after contralateral vertebral artery occlusion. A 36-year-old man presented with brainstem ischemia and was treated non-surgically. Subsequent angiography showed spontaneous vertebral artery occlusion at the site of dissection. A 45-year-old man developed subarachnoid hemorrhage due to vertebral artery dissecting aneurysm. He ...

The two vertebral arteries are usually unequal in size, the left one being generally larger than the right one. It is not clear why this asymmetry exists. One of the hypotheses is that this asymmetry is related to the vascular requirements of the brain. To support this statement, we investigated ...

BACKGROUND: Elongation-induced vertebral artery injury has been hypothesized to occur during non-physiological coupled axial rotation and extension of head. No studies have quantified dynamic vertebral artery elongation during head-turned rear impacts. Therefore, we evaluated effect of rotated head posture vs. forward head posture at the time of impact on dynamic ...

The vertebral artery (VA) is often involved in the occurrence of complications after spinal manipulative therapy. Due to osteophytes compressing the VA anteriorly from the uncinate process or posteriorly from the facet complex, the VAs are susceptible to trauma in the transverse foramina. Such altered anatomical configurations are of major ...

OBJECTIVE AND IMPORTANCE: Basilar artery occlusion is a clinical event with an exceedingly high mortality rate. Improved survival is closely associated with successful recanalization of the occluded basilar artery. Bilateral vertebral artery occlusion (BVAO) is a unique disease entity that effectively denies any direct access to the basilar artery for ...

Summary: We describe the first reported use of simultaneous bilateral vertebral artery rotational angiography to visualize an aneurysm. Images acquired from 3D rotational angiography with a single vertebral injection provided insufficient anatomic detail in two cases with vertebrobasilar junction aneurysms associated with fenestration. Therefore, simultaneous bilateral vertebral artery 3D rotational ...

The dorso-lateral medullary syndrome (Wallenberg's syndrome) is produced by infarction of a wedge of lateral medulla posterior to the inferior olivary nucleus and is usually caused by vertebral artery occlusion. Ipsilateral axial lateropulsion as an initial symptom of vertebral artery occlusion is rather rare and the anatomical structure responsible is ...

Giant mycotic pseudoaneurysms of the vertebral artery are extremely rare. Their management is technically challenging because of the distorted anatomy and intimate relation to the lower cranial nerves. We present a rare case of a 7-year-old boy referred to us by a pediatrician who was treating him for bacterial endocarditis. ...

Endoluminal stent placement is safe and effective in the treatment of symptomatic ostial stenoses of the vertebral artery (VA) and proximal subclavian artery (SCA). However, determining the relative importance of an individual lesion on angiography is difficult when VA and SCA stenoses are concurrent. Pressure-sensing wires help in determining the ...

A 68-year-old man had an unremitting left sixth cranial nerve palsy immediately after completing a long bicycle trip. High-resolution (3 Tesla) magnetic resonance imaging disclosed a dolichoectatic vertebral artery that compressed the left sixth cranial nerve against the belly of the pons at its root exit zone. It was postulated ...

Rotational movements in the territory of vertebrobasilar artery of the head and neck can induce vertebrobasilar insufficiency (VBI) or infarction. The term "bow hunter's stroke" or "rotational VBI" has been used to describe this clinical syndrome. In most cases, symptoms were provoked because of involvement of a dominant vertebral artery ...
