Vertebrobasilar dolichoectasia (VBD) is a common phenomenon among people over 50 years old, and the related clinical expressions are varied. One of our VBD patients presented with brainstem infarction initially, received low molecular weight heparin treatment, and developed rupture of the
OBJECTIVE
Two patients with vertebrobasilar dolichoectasia sustained massive fatal subarachnoid hemorrhage from rupture of the basilar artery wall. Hemorrhage from this entity is not widely known to occur during its natural history and may be exacerbated by systemic anticoagulation.
METHODS
Two
Ischemic lesions of the brainstem can lead to complex neurologic deficits. Failure of the automatic control of ventilation (Ondine's curse syndrome) is a possible but rare syndrome following localized brainstem dysfunction. We report on a 49-year-old man with intermittent bradycardia, cranial
BACKGROUND
We evaluated the efficacy of low-molecular-weight heparin (LMWH) relative to aspirin in preventing early neurologic deterioration (END), venous thromboembolism (VTE), and outcomes at 6 months.
METHODS
Patients were randomly assigned to receive either subcutaneous enoxaparin 4000
A significant but less recognized cause of ischemic stroke and transient ischemic attack (TIA) is atherosclerosis of the vertebrobasilar system, which accounts for 20% of ischemic strokes. Pathology of the vertebrobasilar system can present significant challenges in determining the course of
OBJECTIVE
The purpose of this study was to report on the incidence, diagnosis and clinical manifestation of VAI following cervical spine injuries observed in a prospective observational study with a standardized clinical and radiographical protocol.
METHODS
During a 16-year period, 69 (mean age: 43
OBJECTIVE
Cerebrovascular ischaemia is a rare but serious complication of damage to the carotid or vertebral arteries in the neck caused by blunt injury to the neck. Screening for blunt cerebrovascular injury should be performed in patients with certain signs or symptoms and risk factors. We
Atherosclerotic lesions are very common at the origin and first few centimeters of the vertebral artery in the neck. These lesions are often missed when using noninvasive diagnostic strategies. These lesions cause transient hypoperfusion and transient ischemic attacks, characterized mostly by
BACKGROUND
Vertebrobasilar dolichoectasia is often found in patients with posterior circulation ischemia. Brain ischemia is caused by abnormal flow in the dilated artery and obstruction of paramedian arteries or intraluminal thrombus with artery-to-artery embolism. We report a patient with
We describe the use of abciximab to prevent rethrombosis of the basilar artery after transluminal angioplasty. A 60-year-old patient with vertebral basilar insufficiency and acute occlusion of the basilar artery underwent revascularization with urokinase and angioplasty. Despite the repeated use of
Cerebellar infarction due to vertebrobasilar ischemia in spontaneous vertebrobasilar dissection is infrequent in children and adolescents. The commonest pathogenic mechanism of cerebellar infarction is arterial occlusion. Although usually favorable, outcome can be fatal, as in the present case. A
This study describes a patient with lateral medullary ischemia (LMI) presenting with persistent hiccups followed by vertigo with horizontal head-shaking-induced contralesional nystagmus (HSN) and discusses pertinent pathophysiology. A 65-year-old man presented with persistent hiccups and disabling
In the past 5 years we have investigated 29 patients with symptomatic basilar artery stenoses (14 cases) and occlusions (14) and a patent primitive trigeminal artery with thin-calibered basilar and vertebral arteries (1) using directional continuous-wave Doppler sonography of the vertebral arteries.
