Abstract Background Vertebral artery dissection (VAD), which can possibly lead to stroke, presents various symptoms such as headache, neck pain, transient ischemic attacks, and vertigo. We evaluated the effect of D-dimer to distinguish VAD from benign diseases by retrospective single-center observational study. Methods All VAD cases received in the emergency department between January 2013 and June 2020 were reviewed. Comparing those cases to vertigo with benign etiologies, the correlation between VAD and D-dimer was analyzed. Using stepwise multivariate logistic regression, possible symptoms to suspect VAD were also determined from physical findings and some laboratory data, including D-dimer. Results Eleven patients were included in the VAD group, and 59 patients were enrolled in the control (benign vertigo [BV]) group. The most common symptom in VAD patients was hemiplegia (N = 7, 63.6%) and cranial neuropathy (N = 7, 63.6%), followed by classic occipital or posterior neck pain (N = 4, 36.4%), gait ataxia (N = 3, 27.3%), and confusion (N = 1, 9.1%). Two patients (18.2%) were free from any symptoms except vertigo. D-dimer was not significantly different between the two groups at the positive cutoff value of 500 ng/mL (p = 1). By stepwise selection, age (odds ratio (OR): 0.92, [0.87–0.98], p < 0.01) and systolic blood pressure (sBP; OR: 1.06 [1.02–1.10], p < 0.01) were selected in the diagnostic model. In combination, age under 60 and sBP over 160 mmHg yielded 63.6% sensitivity, 98.3% specificity, and 37.5 positive likelihood ratio. Conclusions In our study, D-dimer was not found to be an effective indicator of VAD. By contrast, disproportionate hypertension (high blood pressure in young patients) can be a key factor to suspect VAD. Future studies with larger sample sizes are warranted.

Carotid Sinus Nerve Stimulation

1. The effects of vascular infusions of acetylcholine, angiotensin II, noradrenaline and prostaglandin F2α on the baroreceptor reflex were studied in the anaesthetized greyhound. 2. Vertebral artery infusions of low doses of angiotensin II, but not of acetylcholine or prostaglandin F2α, resulted in a significant reduction in the depressor response to carotid sinus nerve stimulation. 3. The increases in blood pressure and heart rate in response to bilateral carotid artery occlusion were not significantly changed during vertebral artery infusions of acetylcholine, angiotensin II or prostaglandin F2α. 4. The increases in blood pressure in response to intravenous infusions of noradrenaline were significantly enhanced during vertebral artery infusions of acetylcholine and angiotensin II, but not of prostaglandin F2α. The bradycardia during noradrenaline infusions was significantly enhanced by angiotensin II alone. 5. The depressor response to carotid sinus nerve stimulation was significantly reduced during intravenous infusions of both noradrenaline and angiotensin II. 6. It is considered that although angiotensin II can be shown to have a specific central action to attenuate the response to carotid sinus nerve stimulation, the role of this action in the complete baroreceptor reflex is unproven.

Surgical Extirpation

A 7-year-old girl with a right-sided congenital arteriovenous fistula in the neck was admitted with signs of cardial incompensation. Her fistula was fed from the right vertebral artery in antegrade as well as retrograde directions. A steal from the intracranial arteries was established. In addition, smaller feeding arteries from the neck were found. She was operated on with ligation of the right vertebral artery proximal to the fistula but the attempted ligation of the artery cranially to the fistula was unsuccessful. She was therefore embolized by the formation of a plug of platinum fiber coils in the upper right vertebral artery. Catheterization was performed from the left vertebral artery via the basilar artery. Persisting minor feeders to the fistula from cervical arteries were embolized in a second session. Finally, surgical extirpation of the fistula was performed together with the operative ligation of a crossover feeding artery from the left vertebral artery. Her heart size, heart rate and blood pressure were successively normalized.
