“…Among the ailments most commonly reported in the medical literature, the paroxysmal dizziness of systemic and non-systemic nature is in the foreground. Other complaints, which may coexist or occur as isolated ailments or in groups include gait instability, nausea, double vision, presyncope/ syncope, bilateral tinnitus, hearing loss, cervical radiculopathy and headaches [18,21,22]. Vanrietvelde et al also described the case of a patient complaining of chronic neck pain radiating to both upper limbs for 2 months, in whom vertebral artery loop formation was revealed at the level of C4, coexisting with degenerative changes of the neighboring cervical vertebrae without imaging evidence of the spinal nerve root compression.…”

Currently, Doppler ultrasound examinations are of particular importance, including continuous wave Doppler and color-coded pulsed wave Doppler. Excellent images are obtained using contrast computed tomography angiography (CTA) and magnetic resonance angiography (MRA), which give greater understanding of blood flow in the cranial and intracranial vessels under normal conditions and in pathological situations caused by both anatomical anomalies and acquired abnormalities. Our previous studies, concerning the analysis of the frequency and types of anatomical anomalies of the cranial arteries, i.e. vertebral and carotid arteries, in patients with dizziness and impaired hearing, demonstrated that hypoplasia of the right vertebral artery was the most common anatomical anomaly occurring in 58.7% of cases, of which 51.7% were women and 6.9% men; hypoplasia of the left vertebral artery, occurring in 24.7% of the study group, of which 13.8% were women and 10.3% men; hypoplasia of the right internal carotid artery found in 3.4% of women and of the left internal carotid artery in 6.8% of cases, 3.4% in women and 3.4% in men; and hypoplasia of the right common carotid artery was reported in 3.4% of men, whereas critical stenosis of the left subclavian artery with subclavian steal syndrome was observed in 3.4% of women. Although tinnitus was the most frequent symptom occurring in those patients, in this study dizziness was most common in patients admitted to the Department for the diagnosis, possibly because they found it more disturbing.
