“…The IAA irrigates the cochleovestibular nerve, the cochlea, and the posterior labyrinth. 3 6 Inui et al 14 described in a report of four cases how the AICA emerge from the basilar artery, and the PICA from one of the vertebral arteries in 56% of the cases.…”

“…Nonetheless, this explanation is controversial, because if the basilar artery has a normal blood flow, there would be no reason for decreased perfusion of the terminal circulation. Inui et al 14 reported the case of a patient showing nystagmus when turning the head to the left side, and exams pointed to an occlusion of the ipsilateral vertebral artery. This suggests a decrease in the blood flow on the right vertebral artery; the decreased blood flow in the occluded left artery was not enough to supply the basilar artery, generating the nystagmus.…”

Introduction Vertebrobasilar insufficiency is defined as transitory ischemia of the vertebrobasilar circulation. Dizziness, vertigo, headaches, vomit, diplopia, blindness, ataxia, imbalance, and weakness in both sides of the body are the most common symptoms. Objective To review the literature regarding the three available diagnostic testing in patients with dizziness complaints secondary to vertebrobasilar insufficiency (VBI): magnetic resonance angiography; transcranial Doppler ultrasound; and vertebrobasilar deprivation testing. Data Synthesis We selected 28 studies that complied with our selection criteria for appraisal. The most frequent cause of the hemodynamic changes leading to VBI is atherosclerosis. The main clinical symptoms are dizziness, vertigo, headaches, vomit, diplopia, blindness, ataxia, imbalance, and weakness in both sides of the body. Even though arteriography is considered the most important exam to diagnose the disease, the inherent risks of this exam should be taken into consideration. The magnetic resonance angiography has been widely studied and is a good method to identify and localize any occlusions and stenosis in both neck and intracranial great vessels. Conclusion Each patient with a suspected diagnosis of VBI should be individually evaluated and treated, taking in consideration the pros and cons of each diagnostic testing and treatment option.

“…When symptomatic, the SSS can be manifest with a variety of VBI symptoms such as headache, blurred vision, diplopia, impairment of consciousness, dysarthria, and facial paraesthesiae. Neurotological symptoms, such as vertigo, are also mentioned in VBI and are considered to be of central origin [7][8] . Our patient suffering from SSS and thus from VBI presented with unsteadiness , recurrent vertigo.…”

The subclavian steal syndrome is characterized by a subclavian artery stenosis located proximal to the origin of the vertebral artery. In this case, the subclavian artery steals reverse-flow blood from the vertebrobasilar artery circulation to supply the arm during exertion, resulting in vertebrobasilar insufficiency. As the vertebrobasilar arterial system feeds both the peripheral and central auditory and vestibular systems. In subclavian steal syndrome, neurotological symptoms are expected because of the vertebrobasilar insufficiency. In this report, we describe a patient suffering from subclavian steal syndrome, who presented with isolated dizziness, recurrent vertigo, on moving around, while sitting no complaints were there and no postural vertigo was seen. Upon magnetic resonance imaging no ischaemic lesions were observed, suggesting that the central auditory and vestibular system are more likely to be involved in the pathogenesis of neurotological symptoms in subclavian steal syndrome. Patients complaining of numbness of the upper arm and isolated neurotological symptoms should be thoroughly examined for subclavian steal syndrome. Furthermore, regular follow-up must be undertaken in order to prevent other neurological deficits in the vertebrobasilar arterial territory.

186 GirişProksimal subklaviyan arterin tıkanıklığı veya darlığı nedeniyle vertebral arterden subklaviyan artere olan geri kan akımı subklaviyan çalma sendromu olarak adlandırılır.[1] Nabız ve kan basıncı etkilenen kolda daha düşük olarak bulunur. Klinik olarak her iki kol arasındaki kan basıncı farkı 20 mmHg'yi aştığı durumlarda subklaviyan çalma sendromundan şüphe edilebilir.[2] Semptomlar genellikle arka sisteme ait belirtiler olan diplopi, vertigo, bulantı, kusma, baş ağrısı veya kol iskemisinin neden olduğu kolda güçsüzlük ve ağrı şeklindendir. [3] Vertigo acil serviste en sık görülen şikayetler arasındadır ve genel toplu yetmezlik sebepleri arasında yeralan subklaviyan çalma sendromu da düşünülmelidir. Subklaviyan çalma sendromunda vertigo görülme oranı %52 olarak bildirilmiş-tir.[5] Vertigo genelde bulantı, kusma ve nistagmus ile birlikte görülmekte olup izole olgular nadirdir. [6] Bu yazıda, izole baş dönmesi şikâyeti ile acil servise başvuran ve ileri incelemelerle subklaviyan çalma sendromu tanısı konulan bir olgu sunuldu.
