BACKGROUND: Right-sided subclavian artery stenosis is a rare cerebrovascular disease involving the upper extremities. Considering an endovascular approach for its management requires increased endovascular and catheterization skills, when compared to the left side, due to the close approximation of the right subclavian artery origin, vertebral and common carotid arteries. METHODS: Three patients suffering from proximal right sided subclavian artery stenosis were treated in our center through primary stenting...

BACKGROUND AND PURPOSE: Subclinical atherosclerotic plaques are common in patients with pontine infarctions (PIs) but without basilar artery (BA) stenosis. We hypothesized that BA plaque locations may differ by PI type and vertical location as well as vertebrobasilar artery geometry. METHODS: Ninety-six patients with PI but without BA stenosis on magnetic resonance imaging (MRI) and magnetic resonance angiography were enrolled. PIs were classified by type (paramedian, deep, or lateral) and vertical location (rostral, middle, or caudal)...

Cerebral ischemia because of vertebrobasilar insufficiency (VBI) rarely presents as an initial sign within the systemic lupus erythematosus (SLE) population, and there are very few case reports supporting this manifestation. This report details 3 different patients with SLE who experienced VBI as an initial manifestation. Patient 1 was a 24-year-old female who developed a bilateral pontine lesion as a consequence of basilar artery stenosis. Patient 2 was a 34-year-old male with an acute ischemic lesion on the right side of his cerebellum and pons because of significant stenosis in the distal segment of the right vertebral artery...

Coronary subclavian steal syndrome is an uncommon cause of ischemia recurrence after coronary artery bypass grafting. Endovascular treatment of subclavian artery stenosis or occlusion is increasingly common and appears to offer a safe and effective alternative to surgical revascularization. We report a case of recurrent angina after coronary artery bypass grafting for critical subclavian artery stenosis. The anomalous origin of the vertebral artery from the aortic arch was an indication for endovascular treatment...

OBJECTIVES: Patients with posterior circulation infarction are at higher risk of early recurrent stroke, especially those with vertebrobasilar stenosis or hypoplasia. The clinical presentations of this condition vary over a broad range, making diagnosis and treatment a challenge. Hemodynamic changes and stenosis detected by ultrasonography (US) are sensitive and important indicators for further evaluation. In this study, we correlated extracranial and intracranial US characteristics with brain magnetic resonance imaging (MRI) in patients with posterior circulation infarction...

BACKGROUND: Cervical arterial dissection is a leading cause of stroke in young patients, yet optimal management remains controversial. Existing studies focusing on recurrent stroke were underpowered to demonstrate differences between antithrombotic strategies. Vessel recanalization is a more prevalent outcome and is potentially clinically important. We aimed to assess recanalization rates with anticoagulation compared with antiplatelet therapy. METHODS: We studied a single-center retrospective cohort of patients with extracranial carotid or vertebral artery dissection...

PURPOSE OF REVIEW: Vertebrobasilar stenosis accounts for 20% of posterior circulation strokes and is associated with high risk of early stroke recurrence. We review data from randomized controlled trials examining whether stenting may reduce this risk, including the recently published Vertebral Artery Ischaemia Stenting Trial (VIST). RECENT FINDINGS: VIST and VAST (Vertebral Artery Stenting Trial), having recruited both intracranial and extracranial vertebral stenosis and showed a low rate of perioperative stroke for extracranial (0 and 2%, respectively), but a higher rate for intracranial stenosis (15 and 22%, respectively)...

BACKGROUND: Extreme lateral interbody fusion (XLIF) has rapidly become a popular operative procedure for lumbar canal stenosis and scoliosis. This approach provides direct access to the lateral aspect of the disc with minimal disruption of spinal structures, including ligaments and muscles. However, it involves risk of injuries to the lumbar nerve plexus, segmental artery and intestinal tract because of the limited surgical field. This study aimed to clarify the benefit of using a microendoscope to prevent these injuries...
