BACKGROUND AND PURPOSE Carotid artery dissection (CAD) is more common with increased styloid process length. Our goal was to determine whether proximity of the styloid process and the hyoid bone to the internal carotid artery (ICA) was a risk factor for CAD. METHODS We studied axial slices on computed tomography angiograms of 88 patients with nonaneurysmal CAD, from 88 age- and sex-matched co...

Two dimensional flow of a non-Newtonian fluid through an asymmetric stenosed artery is analysed under the influence of body acceleration with an external magnetic field on the flow field. The Casson fluid model is considered to characterize the non-Newtonian behaviour of the blood. The flow is assumed to be unsteady, laminar, two-dimensional, asymmetric and of pulsatile nature. The artery wall ...

Foucher’s flap is one of the ideal flaps to cover traumatic defect of the pulp and dorsum of the thumb. Though ideally described for thumb defects with some shortening, it has been proved beyond doubt that it can also be requisitioned to resurface thumb defects without shortening. In the latter indication, it is necessary to harvest the flap up to the dorsum of the PIP joint. However, the dista...

2014 Coronary artery disease affects over 5,000,000 people worldwide. Despite technology evolution and extension of indications of drug-eluting and bioresorbable stents, bare-metal stents play an important role to treat single lesions less than 15 mm of length and/or greater than 2.5 mm of diameter. The REBELTM stent is made from a new platinum–chromium alloy combined with a customized stent ar...

Background Aortic arch width (AAW) is defined as the distance between the centroids of the ascending and descending thoracic aorta at the level of the main pulmonary artery bifurcation, measured from an axial image. Previously, in a cohort of >3000 community-dwelling adults who underwent chest computed tomography for research purposes, we found that increased AAW is an independent predictor of ...

Dysarthria, headache, and numbness on the left side developed suddenly in a 70-year-old woman with a history of hypertension , diabetes, and posterior fossa transient ischemic attacks. In 48 hours, the patient became stuporous and had left hemiparesis. On arrival , she was comatose, with pupils in midposition and light-fixed; oculocephalic responses were unobtainable. CT was negative. MR showed...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-204442 DESCRIPTION A 24-year-old woman presented with a swollen right leg and a pulsatile lump in the popliteal fossa 3 days after a diagnostic knee arthroscopy. The CT arteriogram demonstrated a 6 cm pseudoaneurysm of the right popliteal artery (PA). There was early filling of the ips...

To the Editor: We have read with special attention the letter of Davous et al. Because the association between hereditary protein S deficiency and cerebral arterial thrombosis is controversial,' we are reporting another case with this same association in which other members of the family were affected by arterial thrombotic diseases. A 44-year-old man was admitted to our hospital a few hours af...

The arterial lumen is modeled by a spatially continuous right generalized cylinder with piece-wise constant parameters. The method is the identifies the parameters of each cylinder piece from a series of planar contours extracted along an approximate axis of the artery. This curve is defined by a minimal path between the artery end-points. The contours are extracted by use of a 2D Fast Marching...

Several similar projections utilizing cranial and caudal angulation of the X-ray tube in various obliquities have been described recently for coronary angiography and left ventriculography. These views provide improved visualization of the proximal branches of the left coronary artery, the region of the crux of the right coronary artery, and the left ventricle in the left anterior oblique proje...
