For decades, anastomoses between unpaired branches of the abdominal aorta have attracted the attention of anatomists, surgeons and radiologists, due to their significance in many clinical procedures. This report presents a rare anastomosis between the common hepatic artery and the superior mesenteric artery, which gave off three branches to the jejunum. The diameter of the anastomosis measured at the point of its branching off the common hepatic artery and at the level of union with the superior mesenteric artery was 4...

PURPOSE: To investigate the blood supply to the nipple areola complex (NAC) on thoracic CT angiograms (CTA) to improve breast pedicle design in reduction mammoplasty. METHODS: In a single centre, CT scans of the thorax were retrospectively reviewed for suitability by a cardiothoracic radiologist. Suitable scans had one or both breasts visible in extended fields, with contrast enhancement of breast vasculature in a female patient. The arterial sources, intercostal space perforated, glandular/subcutaneous course, vessel entry point, and the presence of periareolar anastomoses were recorded for the NAC of each breast...

BACKGROUND: The anterior commissure (AC) of the human larynx is usually understood as an area of the glottis anteriorly situated between the two vocal folds inserting to the thyroid cartilage (TC). The pattern of spread of AC carcinoma could hypothesize that AC could include other structures of the ventral larynx as developmental anatomy could demonstrate. METHODS: Ten adult larynx specimens from donation program cadavers and 15 selected fetal specimens (from 11 to 34 weeks of amenorrhoea) were studied using microdissection and histological serial sections stained with hematoxylin-eosin and reticuline...

Tetralogy of Fallot (TOF) can be associated with vascular malformations or variations, especially of the aortic arch or supracardiac major venous systems. We report its association with an extremely rare combination of three such variations of the cerebral arteries-a right persistent hypoglossal artery, an extremely rare left carotid-right anterior cerebral artery (ACA) anastomosis, and a left accessory middle cerebral artery arising from the A1-A2 junction of the left ACA-which were diagnosed by magnetic resonance angiography in a 9-year-old girl during evaluation of multiple acute cerebral infarctions...

A 76-year-old male patient underwent magnetic resonance angiography of the head and neck vessels due to a recent incident of transitory ischemic attack. Cerebral angiogram uncovered the double proximal origin of the median unpaired pericallosal artery from the duplicated anterior communicating complex. The vessel curved around the corpus callosum and irrigated the paracentral lobule and the medial parietal cortical areas. The main trunks of the anterior cerebral arteries showed a branching pattern of the marginal callosal arteries, supplying orbital and frontal territories...

PURPOSE: Three-dimensional (3D) movement of the clinical subtalar joint (CSTJ) is primarily determined by the morphology of the articular surfaces of the talus. The purposes of this study were to assess the 3D orientation of the CSTJ facets of the talus and the talar head and to determine the tri-axial angular relationship. METHODS: Fifty dry tali were scanned using computed tomography to create a 3D bone model of the talus. The tri-axial angles of the anterior, middle, and posterior facets and the talar head were calculated...

The precise description of the fascia vasto-adductoria (FVA) has become an issue of great surgical and clinical importance. Neurovascular entrapment within the adductor canal (AC) may simulate many clinical conditions for cases presented with medial knee or leg pain and ischemic manifestations of the leg. The aim of the present work is to describe the morphological features of the FVA and to elucidate its neurovascular relations. Forty thigh specimens, pertaining to 15 embalmed and five fresh adult human cadavers, were dissected in pursuit of this aim...

PURPOSE: Neural foraminal dimensions are considered important in nerve root compression and development of cervical radiculopathy, but baseline data regarding their range during normal motion are not available. An in vivo study of cervical foraminal motion was conducted to characterize normal 3D dynamic foraminal dimensions during physiological neck motion and compare between different tasks and intervertebral segments. METHODS: Biplane X-ray imaging and computed tomography-based markerless tracking were used to measure foraminal height (FH) and width (FW) from five asymptomatic subjects during neck axial rotation and extension...

The "non-recurrent" course of the inferior laryngeal nerve (ILN) is an anatomical variant which must be borne in mind during thyroid surgery. The "non-recurrent" course of the ILN on the right side is associated with the aberrant right subclavian artery (arteria lusoria), and, on the left, is described in situs viscerum inversus. We present a case in which the "arteria lusoria" was not associated with the non-recurrent right ILN. The aims of this paper are to report this "anomaly of the anomaly" to surgeons who may be unaware of it on the one hand and on the other to emphasize that this is the only case so far reported in the literature...

INTRODUCTION: The triticeal cartilage (TC) is a small cartilage found within the thyrohyoid membrane. The TC has a variable prevalence between and within individuals. It has been suggested that absence of a TC results from its failure to separate from the superior horn of the thyroid cartilage (SHTC) and that individuals without a TC will have a longer SHTC. This study aims to identify the prevalence of the TC and investigate the relationship between the length of the SHTC and presence of a TC...
