Arch index as a predictor of arch height
The Foot, 1997Abstract A number of indirect methods of estimating the height of the medial longitudinal arch of the foot have been devised.1 The efficacy of the arch index as a valid and convenient predictor of arch height has been questioned.2 In this study, arch index was measured in 45 elderly subjects and navicular height was measured from weight bearing ...

Coarctation and hypoplasia of the aortic arch: Will the arch grow?
The Annals of Thoracic Surgery, 1991Hypoplasia of the transverse aortic arch of various degrees of severity is commonly seen in infants who have coarctation of the aorta. It is more often present when the coarctation is associated with intracardiac lesions that diminish or limit forward flow in the ascending aorta and promote right to left flow through an arterial duct.

Structure and Infrastructure Engineering, 2012
People have been building beautiful arch bridges for more than 2000 years. From the spectacularly solid Roman arch to today's elegant and graceful styles, there are a large variety of arch shapes. The development of arches was influenced by the construction materials available at the time.

Today arches are usually made of steel or of reinforced or prestressed concrete and can support both tensile as well as compressive loads. They are used to support bridge decks and roofs and vary in span from a few metres in a roof support system to several hundred metres in bridges. A fine example of a steel arch bridge is the Sydney Harbour Bridge in

Double Aortic Arch with Left Arch Atresia
Heart, Lung and Circulation, 2009A girl, having an echocardiogram suggestive of double aortic arch, underwent a cardiac multidetector computed tomography (MDCT) examination. MDCT revealed double aortic arch with left arch atresia distal to the left subclavian artery. The left common carotid artery and the left subclavian artery arose from the left arch, the right common carotid artery

Total Arch Replacement for a Distal Aortic Arch Aneurysm With Right Aortic Arch
The Annals of Thoracic Surgery, 2007Right-sided aortic arch accompanied by an aberrant origin of the left subclavian artery is rare and seen in 0.05% approximately 0.1% of the population. A 73-year-old woman with this anomaly was admitted to our institution because of the enlargement of the distal aortic arch aneurysm. She also had mild dysphagia.
