INTRODUCTION: Subclavian artery pseudoaneurysms are rare and occur mostly as a consequence of an inadvertent arterial puncture during central venous catheterization, endovascular therapeutic procedures or after penetrating or blunt trauma. They usually have a late clinical presentation, with pain, swelling or other compressive symptoms. The optimal treatment in this situation is still a matter of debate. The authors describe a case of late presentation of subclavian artery pseudoaneurysm after transjugular hepatic biopsy and discuss the several options for treatment...

BACKGROUND AND PURPOSE: Quantitative arterial tortuosity (QAT) is a ratio of vessel length between 2 points to the shortest linear distance between same points. QAT has been reported as an imaging biomarker of arteriopathy in pediatric arterial ischemic stroke (AIS) because of dissection and transient cerebral arteriopathy. We sought to determine whether QAT abnormalities are present in other subtypes of pediatric AIS. METHODS: Children with AIS-absent conventional biomarkers of arteriopathy and case-controls who underwent magnetic resonance angiography were classified by stroke mechanism...

Fibromuscular dyplasia (FMD) is an under-recognized non-atherosclerotic, non-inflammatory arteriopathy that occurs most commonly in middle-aged women, but may affect individuals of all age groups. FMD may result in stenosis, aneurysm, dissection, occlusion, or arterial tortuosity. Recently published data demonstrated a genetic association of FMD with a variant in the phosphatase and actin regulator 1 gene (PHACTR1), substantiating that the pathogenesis of this condition has genetic contribution. The renal and extracranial carotid and vertebral arteries are most often involved, although any arterial bed may be affected...

Objective: The objective of this study is to determine whether structural features of the vertebrobasilar arterial system are related to migraine. Background: Alterations in cerebral vascular structure and function have been associated with migraine, possibly mediated by hypoperfusion and/or endothelial dysfunction triggering cortical spreading depression. Vessel tortuosity, in particular, has been associated with both altered hemodynamics and endothelial function...

Background: Although vertebral artery (VA) dissecting aneurysms are treated by direct or endovascular surgery, some disadvantages are associated with each surgery. Therefore, the type of surgery should be selected based on the condition of the aneurysm. We performed aneurysm trapping by endovascular surgery via the contralateral VA after proximal direct ligation with bypass to prevent complications as well as achieve complete treatment. Case Description: We attempted to insert a distal clip to achieve complete trapping of the ruptured VA dissecting aneurysm after proximal ligation with occipital artery-posterior inferior cerebellar artery (PICA) anastomosis; however, the operative field was limited by the existence of lower cranial nerves, brain swelling, and tortuosity of VA...

BACKGROUND Vertebrobasilar dolichoectasia (VBD) is a complex progressive arterial disease characterized by dilation, elongation, and tortuosity of the vertebral and basilar arteries, and may be congenital or acquired. VBD may lead to progressive compression of the brainstem, cranial nerve abnormalities, and intracranial hemorrhage, but may also be associated with arterial thrombosis, with ischemic stroke as the most common clinical outcome. CASE REPORT Two cases of VBD are presented, both with acute bilateral ophthalmoplegia and cranial nerve palsies, and vertebrobasilar arterial thrombosis that resulted in ischemic stroke...

Dolichoectesia is described as elongation, widening, and tortuosity of an artery. Most commonly involved vessels are the intracranial vertebral and basilar arteries. Vertebrobasilar artery dolichoectesia is usually asymptomatic. Cerebral ischemia, hemorrhage, or compression findings due to mass effect can be seen in symptomatic patients. Although there are case reports of trigeminal neuralgia due to fifth cranial nerve compression in the literature, to the best of our knowledge, neither hemicranial nor continuous facial pain secondary to vertebrobasilar artery dolichoectesia has been reported previously...

Giant thrombosed aneurysms of the vertebral artery (VA) are difficult to treat. Moreover, marked tortuosity of the parent VA complicates determination of the surgical approach. We report the case of a 71-year-old male patient who presented with gait disturbance. Magnetic resonance imaging revealed a giant thrombosed aneurysm of approximately 4cm in diameter located in the ventral region and to the right of the medulla oblongata. Computed tomography angiography showed that the right VA had extreme tortuosity, and that the VA union was in contact with the left 7th and 8th cranial nerves...

BACKGROUND: Tortuous or occluded vertebral arteries (VAs) can make the endovascular treatment of vertebrobasilar insufficiency impractical. Bypass surgery is an option, but a craniotomy of the posterior fossa is complicated when physiologic vessels must be abandoned. We report 3 cases of refractory vertebrobasilar insufficiency with different presentations requiring problematic approaches in which the patients were treated by different hybrid strategies. CASE DESCRIPTION: Patient 1 had severe stenosis of right VA ostium with right V1 segment tortuosity and was treated by right VA ostium transposition during which the proximal subclavian artery was blocked by a balloon guide catheter...

PURPOSE: Main symptom of mucopolysaccharidosis type IVa (MPS IVa) is progressive systemic skeletal dysplasia. This is routinely monitored by cerebral and spinal MRI. The vascular system is generally not in the primary focus of interest. In our population of MPS IVa patients we observed vessel shape alterations of the vertebrobasilar arteries, which has not been described before. MATERIAL AND METHODS: MRI-datasets of 26 patients with MPS IVa acquired between 2008 and 2015 were eligible for retrospective analysis of the vertebrobasilar arteries...

PURPOSE: The aim of this study was to test the hypothesis that patients with spontaneous cervical artery dissection (CeAD) have increased arterial tortuosity, and the objective quantification of such a tortuosity may aid in the identification of subjects at increased risk of disease. METHODS: In the setting of a hospital-based, case-control study, we used the vertebral tortuosity index (VTI) measured on magnetic resonance angiography, a validated method for the assessment and quantification of arterial tortuosity, to compare the degree of tortuosity in a series of consecutive patients with spontaneous CeAD and of age- and sex-matched patients with ischemic stroke unrelated to CeAD (non-CeAD IS) and stroke-free subjects...

OBJECTIVES: Aneurysms of the proximal posterior inferior cerebellar artery (PICA) are rare. The management of proximal PICA aneurysms is challenging with either surgical or endovascular treatment. We report our successful experience of treating PICA aneurysms with a multimodal approach. METHODS: Of 2382 treated aneurysms, 22 aneurysms in 21 patients (male:female 8:13, mean age 48.9 years) were enrolled from March 1998 to December 2015. We treated the aneurysms with a multimodal approach and performed angiography to examine aneurysm regrowth at the 12 months follow-up...

BACKGROUND: Bow hunter's syndrome is a dynamic and reversible occlusion of the vertebral artery occurring after rotation or extension of the neck. The V3 segment is the most common site of compression, especially at the atlantoaxial joint. Surgical decompression with or without cervical fusion has been the mainstay of therapy. Endovascular intervention, such as placement of stents, is rarely performed. METHODS: We report a patient with bow hunter's syndrome from tortuosity of the V1 segment of the VA treated with a self-expanding biliary stent placement...
