Pathophysiology and Diagnosis of Vertebrobasilar Insufficiency: A Review of the Literature

The most frequent cause of the hemodynamic changes that lead to the development of VBI is atherosclerosis. Other common causes are: embolism, atherosclerosis of great vessels, and arterial dissection. Migraine, fibromuscular dysplasia, coagulopathies, and drug abuse are less frequent causes.7

A Loop That Matters—An Unusual Case of Bow Hunter’s Syndrome

Bow Hunter’s syndrome (BHS), also known as rotational vertebral artery occlusion (VAO), is a rare condition in which vertebral artery is reversibly compressed due to rotation or extension of the head.

A review of the diagnosis and management of vertebral basilar (posterior) circulation disease

It must be recognized that PCD differs from ACD. First emergency room physicians and neurologists should be aware of the early non-specific symptomatology of PCD, which leads to a more rapid development of stroke than ACD.

Can popping your neck cause a stroke?

The two vertebral arteries (major arteries of the neck) join up to form the basilar artery that supplies the back of the brain with blood. They are vulnerable to injury by rotation and bending of the neck, as they pass through bony canals in the side arms of the vertebrae and are stretched when the neck is turned.

Clinical Diagnosis of Vertebrobasilar Insufficiency: Resident’s Case Problem

Although the value of cervical extension and/or rotation screening procedures is questionable at the present time, positive findings with these tests should warrant caution.

Diagnostic Investigations as a Basis for Optimising Surgical Management of Vertebrobasilar Insufficiency Syndrome

Choosing the type of surgical treatment for patients with VBI is an unresolved medical problem. The key difficulty in the diagnostic process lies in the multiple possible etiologies of this pathology. The process of determining the differential diagnosis is quite time-consuming and, in our opinion, this is one of the reasons for the small number of operations for patients with VBI syndrome.

New Way to Correctly Diagnose Disorders of Blood Supply of the Brain

VBI is one of the most common cerebrovascular pathologies. The progression of VBI, especially due to inadequate therapy, often leads to permanent impairment of neurological functions. The choice of the type of surgical treatment for patients with VBI remains an unresolved medical problem.

Suspecting a Patient Has VBI? You Could Recommend This

The probability of a patient arriving to your outpatient, physical therapy office with symptoms associated with vertebrobasilar insufficiency (VBI) is very, very, very minimal. VBI is an important diagnosis to consider, as many symptoms can mimic benign peripheral etiologies in our industry.

The Diagnosis of Vertebrobasilar Insufficiency Using Transcranial Doppler Ultrasound

Vertebrobasilar insufficiency (VBI) is a hemodynamic posterior circulation transient ischemic attack (TIA) caused by intermittent vertebral artery occlusion that is induced by a head rotation or extension. VBI may result from large vessel atherosclerotic disease, dissection, cervical compressive lesions, and subclavian steal phenomenon.

Updates about Vertebrobasilar Insufficiency in Dizziness

Vertebrobasilar insufficiency (VBI) is a result of transitory ischemia of the vertebrobasilar arterial system (VBS) that can produce a variety of symptoms that are on their own are ambiguous. Symptoms include dizziness, vertigo, lightheadedness, headaches, visual changes, diplopia, ataxia, weakness in limbs, pain and stiffness of the neck. Vestibular and visual symptoms can arise suddenly and dissipate rapidly as well, all while preceding more serious symptoms like stroke and death.

Vertebrobasilar disease may be a challenge to pinpoint

In some patients with vertebrobasilar disease, there are only ocular manifestations of the disease.

Vertebrobasilar Insufficiency

The term, VBI, was coined in the 1950s after C. Miller Fisher used carotid insufficiency to describe transient ischemic attacks (TIA) in the carotid supplied territories and is therefore often used to describe brief episodes of transient ischemic attacks in the vertebrobasilar territory.

Vertebrobasilar Insufficiency

Transient ischemia within the posterior circulation supplied by the vertebrobasilar artery system is a common cause of episodic dizziness in older patients. Vertebrobasilar insufficieny (VBI) has been used as an umbrella term indicating a hemodynamic cause of all cases of posterior-circulation ischemia.

Vertebrobasilar Insufficiency: Getting Your Neck ‘Cracked’

But often they are not aware of the serious risk that they face. The risk of vertebrobasilar insufficiency (VBI), or vertebral basilar ischemia to be exact. VBI is temporary reduction in the blood flow to the back of the brain.
