Vertebrobasilar insufficiency (vbi) | pathophysiology, risk

The controversies and confusions surrounding the diagnosis of vertebrobasilar insufficiency, also known as vertebrobasilar artery insufficiency, rotational vertebral artery occlusion syndrome, or Bow Hunter Syndrome, demonstrate the difficulty and challenges of cervical neck instability care. The fact that this one diagnosis or explanation of symptoms has at least four diagnostic names should be proof enough that patients and physicians don’t really know what they’re dealing with.
As a patient who has been diagnosed with one of these diagnostic marks, you are probably well aware that your recovery process has taken several twists and turns. Others are correct, while others are incorrect, but if you are reading this post, your healing journey is most likely not yet complete.
When a patient first walks into our office, we sit down with them and begin talking about their symptoms, medications, and medical history up to that point in our examining room. Let’s see if any of this sounds familiar.

The VA test usually involves moving the cervical spine to an end-range place of rotation, extension, or a combination of the two. At this stage, the doctor checks for symptoms of vertebrobasilar insufficiency (VBI). It is considered a good outcome and a contraindication for cervical manipulation if the patient experiences VBI symptoms during the procedure. 1st

Graph 17. Competency exam for the vertebral arteries (VACT). The VACT tests the ability of the vertebral arteries to deliver blood to the back of the brain. The therapist instructs the client to twist his or her neck to one side before extending and laterally flexing it to the other side. (Photo by Joseph E. Muscolino.) Yanik Chauvin took the photos.)

As a clinician, we understand that conducting cervical manipulations can be frightening. Here’s a free video from our Insider Access Page on how to measure cervical spine mobility to aid you in your evaluation. Have fun!
The aim of this study is to determine the function of vertebral artery occlusion in the patient’s symptoms.
Sitting is the test position.
Performing the Examination: Patient rotates head maximally to the side opposite the checked side and retains place for 10 seconds. For ten seconds, the patient is in neutral. For ten seconds, the patient stretches his back. For ten seconds, the patient is in neutral. For 10 seconds, the patient stretches and rotates his head maximally (again on the opposite side of the examined side). Dizziness, diplopia, dysarthria, dysphagia, drop attacks, nausea and vomiting, sensory changes, nystagmus, and other positive signs include (The 5 D’s). Accuracy of diagnosis: “Cote P et al. J Manipulative Physiol Ther. 1996.” Sensitivity: 0 percent; Specificity:.67-90 percent; +LR:.21-.87; -LR: 1.02-1.40. The Test’s Importance: If a patient’s Vertebral Artery test is positive, they could have Vertebrobasilar Insufficiency (VBI); but, if the test is negative, you CANNOT rule out Vertebrobasilar Insufficiency. The idea behind this test is to extend the opposite vertebral artery as far as possible in order to reduce the space in the artery’s lumen. The direction of extension with contralateral rotation has been shown to reduce the artery’s diameter, but the test’s diagnostic accuracy is still low. Notice that only a professionally qualified health care provider can perform these assessments.
