Various surgical techniques have been developed for the repair of an interrupted aortic arch. However, tension and Gothic arch formation at the anastomotic site have remained major problems for these techniques: Excessive tension causes arch stenosis and left main bronchus compression, and Gothic arch configuration is related to cardiovascular complications. To resolve these problems, we adopte...

Foot arch is important for force transfer and shock absorption in impact sports. The purposes of this study were to measure the height of foot arch in static standing and dynamic activities, and to compare the difference of foot arch between level walking, vertical jump and sprint start. Twenty-three healthy subjects were recruited in this study. Significant differences between non-weight beari...

BACKGROUND The branch anatomy of the aortic arch varies widely between individuals. These are likely due to alterations in the development of aortic arch arteries during the embryonic period. The purpose of this study is to determine the frequency of the aortic arch branch variations in the local population and provide useful data to intervention radiologists, neck and thoracic surgeons. METH...

OBJECTIVES Systemic hypertension is the main late complication after arch reconstruction in patients with arch obstruction. Gothic arch geometry is suspected to be one of its possible causes. Accordingly, we evaluated here if a modified arch repair technique using an autologous pulmonary patch is effective in preventing gothic arch development. METHODS Fifty infants who underwent arch repair ...

conclusions this approach may be an appropriate approach to the zygomatic arch in the zmc fractures and eliminates the use of the coronal flap. introduction zygomatic arch fractures are common injuries in the maxillofacial injuries. sometimes it is necessary to fix the unstable fragments of the zygomatic arch. case presentation we introduce a combination of transconjunctival and lateral canthot...

Objective Duplication of the vertebral artery (VA) is a rare vascular variant. This paper describes the anatomy and embryological development of duplicated VAs and reviews the clinical significance. Methods Computed tomography (CT) angiography was performed in 3386 patients (1880 females, 1506 males) between March 2014 and November 2015. We defined duplication of the VA as a condition in whic...

mobile luminal mass of aortic arch is an unusual finding in patients with peripheral embolization. to search the source of these emboli, aortic arch mass should be considered. to our knowledge, transesophageal echocardiography (tee) can be a useful modality to demonstrate the nature and exact location of the mass. this report is illustrative of a large mobile aortic arch mass, histologically th...

BACKGROUND The prevalence of flexible flatfoot is high among preschool-aged children, but the effects of treatment are inconclusive due to the unclear definitions of normal flatfoot. To date, a universally accepted evaluation method of the foot arch in children has not been completely established. Our aims of this study were to establish a new method to evaluate the foot arch from a three dimen...

this paper discusses the arching effect as the formation of a stable arch in granular materials. for this aim, a developed trapdoor apparatus is designed in order to investigate the arch dimensions in term of the internal friction angle, average size and base angle of materials. observations show that for all tested granular ensembles, width and height of the arch increase with an increase in t...
