This variation occurs in as much as 27% of the population and is more common in African-Americans.A bovine arch is so named because the branches of the brachiocephalic artery and the left common carotid artery all originate together from the aortic arch, instead of being separated as is typical. It is important to know the limits of expansion of the stent while still retaining the strut architecture, which provides adequate radial resistance to compression. An additional degree of safety can be afforded if a longer sheath (30-45 cm) is inserted into the brachial artery and wire access into the vertebral artery is obtained via this access. This relatively short artery supplies oxygenated blood to the head, neck and arm regions of the body.Regina Bailey is a board-certified registered nurse, science writer and educator. Studies investigating the placement of bare metal stents are sparse and have had mixed outcomes [,The results of a small prospective randomized controlled trial of patients with recurrent CAS have shown that the use of covered stents (Fluency, Bard) results in better patency than the use of bare metal stents (Luminexx, Bard) [,Surgical turndown, in which the cephalic vein just peripheral to the cephalic arch is dissected, tunneled subcutaneously, and anastomosed to the side of the axillary or basilic vein, is a seldom-used alternative to endovascular treatment of CAS. These other access routes also provide alternative methods for imaging or insertion of protection devices while trying to intervene for treatment of stenotic lesions (.Many of the techniques described here are applicable to interventions in the other vessels in this distribution and can be helpful to keep in one’s armamentarium. Care must be taken when performing this procedure because the occlusive process in the vessels usually extends into the aortic arch, and debris can be dislodged by simply placing a wire across the arch.

The brachiocephalic (Brachi-, -cephal) artery extends from the aortic arch to the head. Options for this initial access include the vertebral (Cook, Inc., Bloomington, Indiana), Headhunter (Cook, Inc., Bloomington, Indiana), and angled Glide (Terumo, Tokyo, Japan) catheters.

For the approximately 640,000 patients in the United States with end-stage renal disease (ESRD), the majority (64.2%) undergo renal replacement therapy via hemodialysis. Additionally, rotation of the vessel origins around the arch toward the ascending aorta can make access and intervention much more challenging, and in some cases, such rotation may make surgical treatment of the disease preferable (.Knowledge of the extent of disease within the vessels is important when planning arch interventions. Frequently, technical failure was not a function of an inability to cross the lesion with a wire but instead an inability to cross the lesion with the dilating balloon. Frequently, it is helpful to rotate the imaging acquisition arm with a wire in place across the arch so that the optimal projection to fully open the arch can be identified. There are two additional variations of the bovine arch that are much less common.Most anatomical variations of the brachiocephalic artery are asymptomatic (have no medical complaints).The brachiocephalic artery carries blood from the.Despite the fact that there are two arms and two sides of the brain, the brachiocephalic artery only occurs once and only supplies the right arm and right side of the brain. In this configuration, the easiest of the arch branches to access is the left subclavian artery, and the most difficult to access is often the innominate artery.

While the operator simultaneously injects contrast material and slowly retracts this unformed catheter, the catheter will form at the anastomosis with the tip entering the proximal radial artery.

… Quatre des 13 patients étaient des garçons. If a balloon-expandable stent is used in this region, it may be possible to place a 0.035-inch system over both wires and position the stent over both wires.

Both inflow and outflow stenoses lead to poor access flows and can subsequently cause access thrombosis.For the treatment of JAS, some investigators recommend surgical revision, whereas others perform endovascular dilation. In most instances, this is best achieved with a forward-facing catheter with minimal angulation. The imaging is best performed in the left anterior oblique projection so that the arch can be “opened up” on the imaging screen.
