Abstract. The method for identifying the line of thrust closest to geometrical axis an undamaged arch, developed by authors in a publication 2019 first time, is extended this paper case cracked arches. Cracks subdivide arch into rigid portions linked in-between correspondence points at extrados or intrados, which can be interpreted as internal hinges. Under assumption, procedure reformulated an...

Background: Arch-height estimation though practiced usually in supine posture; is neither correct nor scientific as referred in literature, which favour for standing x-rays or archindex as yardstick. In fact the standing x-rays can be excused for being troublesome in busy OPD, but an ink-footprint on simple graph-sheet can be documented, as it is easier, cheaper and requires almost no machineri...

BACKGROUND Whether a hypoplastic transverse arch will grow after successful coarctectomy remains controversial. METHODS We studied 15 coarctation specimens with hypoplastic transverse arch. Eight patients were less than 1 month old and 7 were between 1 and 3 months. The diameter and length of the various segments of the aortic arch were measured. The number of elastin lamellae was determined ...

Background Vascular ring is less than 1% of congenital heart disease. Double aortic arch (DAA) is the most common form of it.  Its detecting is important because of the effects of pressure on the esophagus and trachea. Case Report In this study, three children suffering from double aortic arch with symptoms of dysphagia and recurrent aspiration, which in two cases had led to cardiac arrest, wer...

PURPOSE The axillary arch is an anomalous muscle that is not infrequently encountered during axillary sentinel lymph node biopsy (SLNB) of breast cancer patients. In this study, we aimed to investigate how often the axillary arch is found during SLNB and whether it affects the intraoperative sentinel lymph node (SLN) identification rate. METHODS We retrospectively analyzed the correlation bet...

RATIONALE Apolipoprotein E-null mice with a 129S6/SvEvTac strain background (129-apoE) develop atherosclerotic plaques faster in the aortic arch but slower in the aortic root than those with a C57BL/6J background (B6-apoE). The shape of the aortic arch also differs in the 2 strains. OBJECTIVE Because circulating plasma factors are the same at both locations, we tested the hypothesis that gene...

The role of aortic arch angiography in the evaluation of cerebral ischemic disease is not well defined. In an attempt to develop guidelines for its optimal use, a prospective study of 100 patients with carotid distribution ischemic events was undertaken. Each patient underwent bilateral selective carotid angiography followed by arch aortography. In only two of the cases did the arch examination...

The cephalic arch is a common location of stenosis, especially in brachiocephalic fistulas. The cephalic arch has a number of anatomic variations. Cephalic arch stenoses are often resistant and have poor primary patency. Here we describe an unusual case of a hemodialysis patient with a single-conduit supraclavicular cephalic arch draining into the external jugular vein presenting with recurrent...

Isolated atresia of the aortic arch is rare. In aortic arch atresia the arch is continuous, yet a segment of it is atretic so that apart from a collateral circulation, communication with the lower aortic segment is absent. Haemodynamically, the condition is similar to complete interruption of the aortic arch. To our knowledge only 10 cases of isolated aortic arch atresia or interruption have be...
