“…There was no statistically significant correlation between the sides of the vessel, gender, and the location of measurement, even though the variation was observed more frequently in the left artery. This is consistent with the suggestions of other authors of a dominant left VA with a wider lumen and longer segment than the contralateral one in 50-70% if individuals [15,19,21].…”

“…These results are similar to ours (see Table 1) and are also consistent with the conclusions of the other studies that the left V 4 is dominant more often than the right artery [1,23]. According to the published anatomical data, the left VA has a wider lumen and longer segment than the contralateral one in 50-70% of individuals [15,19,21]. Statistical differences in VA diameter between genders were not observed.…”

“…Some authors agree with a hypothesis that duplication and fenestration predispose the patient to coexisting vascular anomalies (aneurysms, vascular malformations, vertebral dissection etc.) [21,26,29]. Such vascular anomalies may result from changes in the construction of the vascular wall and altered haemodynamics (the turbulent blood flow) [3].…”

The presented knowledge of anatomical variation and abnormali-ties of vertebral circulation can improve the accuracy and "safety" of the surgical procedures in this region, help to determine the range of surgical approach and avoid associated complications. The radiological examinations using 3D CT, DSA reveal unlimited observation of anatomical structures in contrast to studies based on cadavers, and can complement the morphometry in anatomical preparations.

BackgroundThe right-sided aortic arch (RAA) is a rare congenital defect of the aorta. The aim of the study was to assess the occurrence of RAA in diagnoses performed by the University Radiology Department and analyze the frequency of concomitant vascular abnormalities.MethodsThe database of the Radiology Department was retrospectively analyzed between January 2008 and May 2016 with the keyword “right aortic arch”. Twenty patients with this diagnosis were identified from a total of 11,690 CT examinations of the chest area, 19,623 CT examinations of brain-supplying vessels, and 1863 MRI examinations of the heart and aortic arch or brain-supplying arteries. The type of aortic arch, the occurrence of Kommerell’s diverticulum and possible other vascular abnormalities, such as stenosis, kinking or occlusion, were then investigated.ResultsThe analysis identified nine patients with type I and 11 patients with type II RAA. Eight of the 11 type II patients presented Kommerell’s diverticulum. Concomitant vascular abnormalities were detected in four patients with type II RAA. In two cases, the right common carotid artery (RCCA) was narrowed by up to 80%, with steal phenomenon confirmed in one of them. In the second coincident right subclavian artery (RSA) stenosis was depicted. In two other cases, the aberrant left subclavian arteries (ALSA) were found to be narrowed at the level of origin by up to 70%. One patient was found with type B aortic dissection including ALSA and Kommerell’s diverticulum.ConclusionsOur observations indicate that concomitant vascular abnormalities may occur more often than reported in literature. Patients diagnosed with type II RAA should be examined with Doppler ultrasonography to identify coincident vascular disorders, especially stenosis of the common carotid arteries or subclavian arteries.Electronic supplementary materialThe online version of this article (doi:10.1186/s12872-017-0536-z) contains supplementary material, which is available to authorized users.

“…Fenestration is a rare developmental vascular anomaly that can occur in multiple cerebral arteries, with vertebrobasilar fenestration being commonly reported [1,2]. Proximal basilar trunk and extracranial segments of the vertebral artery at the upper cervical level are more commonly seen in basilar and vertebral artery fenestration (VAF), respectively [3,4]. Fenestration of the V1 segment of the vertebral artery, however, is an extremely rare presentation [5].…”

Background: Fenestration of vertebra-basilar artery is an uncommon congenital vascular anomaly, which is identified by incidental findings on imaging in patients presented without related symptoms or in patients with intracerebral hemorrhage secondary to concomitant artery aneurysm or arteriovenous malformations. Yet, cases of fenestration being misdiagnosed as cerebral artery dissection have never been reported. Case presentation: We present a patient of 66-year-old female with acute onset of dizziness after chiropractic manipulation of the neck. Neck computed tomography angiography (CTA) showed 'double lumen' sign and 'intimal flap' of the V1 segment of the vertebral artery, which led to the initial diagnosis of vertebral artery dissection (VAD). However, vertebral artery fenestration at V1 segment was eventually identified by multi-directional digital subtraction angiography (DSA). Interestingly, concomitant vertebral fenestration at V3 segment, basilar fenestration and basilar artery tip aneurysm was also revealed by DSA. Conclusion: The triple fenestration at vertebrobasilar artery with basilar tip artery aneurysm is extremely rare, and the fenestration at the V1 segment of vertebral artery was easily misdiagnosed as VAD due to the similar imaging morphology.
