How is vertebral artery hypoplasia treated?
The right vertebral artery was hypoplastic and ended at the level of the posterior inferior cerebellar artery. After discussion with the patient, it was decided to treat the lesion by placing a stent. A 5×20 mm Acculink stent was placed across the lesion and deployed.
What is vertebral artery hypoplasia?
Vertebral artery hypoplasia is a congenital anatomical variation characterized by underdevelopment of the vertebral artery.
What does it mean when an artery is hypoplastic?
Abstract. Vertebral artery hypoplasia (VAH) is a frequent anatomical variation of vertebral arteries, with emerging evidence suggesting that it contributes to posterior circulation ischemia.
What causes vertebral artery insufficiency?
Atherosclerosis or “hardening of the arteries” is the main cause of vertebrobasilar disease. The narrowing of the vertebral or basilar arteries caused by atherosclerosis creates vertebrobasilar insufficiency (VBI), or an insufficient delivery of blood flow to the posterior structures of the brain.
How do you treat a vertebral artery dissection?
First-line treatment for cervical artery dissection usually is antiplatelet agents (such as aspirin) or anti-coagulation to prevent the formation of blood clots. Antiplatelet drugs such as aspirin or clopidogrel may used alone or in combination.
Which vertebral artery is dominant?
A vertebral artery was considered dominant when a side-to-side diameter difference >0.16mm exists. In 54% of the cases the left diameter was dominant, whereas in 30% the right diameter was dominant. In 16% of the cases, the left arterial diameter was equal to the right (Table 3).
How do you treat a blocked vertebral artery?
Endovascular repair It involves the placement of a catheter in an artery of the groin through a small nick in the skin. A balloon is advanced to the vertebral artery where it is inflated, expanding the artery wall. A tube-like metal stent may be inserted to keep the artery open and the blood flowing freely.
What part of the brain does the vertebral artery supply?
The vertebral artery delivers blood to the neck’s vertebrae, upper spinal column, the space around the outside of the skull. It also supplies blood to two very important regions of the brain: the posterior fossa and the occipital lobes.
What is the treatment for atresia of the right vertebral artery?
The described case of an atresia of the right vertebral artery emphasizes the necessity of adequate preoperative assessment, which could improve neurologic outcome. A more individualized surgical strategy would have been chosen with a better preoperative diagnosis.
What is bowhunter’s syndrome of the vertebral artery?
Bowhunter’s syndrome, also known as rotational occlusion of the vertebral artery, involves posterior circulation ischemia resulting from dynamic compromise of the dominant vertebral artery.
What is the pathophysiology of vertebral artery hypoplasia?
Vertebral artery hypoplasia is associated with a decrease in net vertebral flow volume.Ultrasound Med Biol. 2010; 36:38–43. Crossref Medline Google Scholar
Does vertebral artery hypoplasia impede perfusion in the dependent pica territory?
Vertebral artery hypoplasia (VAH) is supposed to be a risk factor for posterior circulation ischemia (PCI), particularly in the territory of the posterior inferior cerebellar artery (PICA). The aim of our study was to determine whether VAH impedes perfusion in the dependent PICA territory even in the absence of manifest PCI.
