Bifurcation Anatomy

The new bifurcation model provides a comprehensive assessment of bifurcation anatomy. Compared with straight analysis, identification of lesions with preserved FFR values in obstructive bifurcation stenoses was improved. Nevertheless, accuracy was limited by using solely anatomical parameters The aortic bifurcation is the point at which the abdominal aorta bifurcates (forks) into the left and right common iliac arteries. The aortic bifurcation is usually seen at the level of L4, just above the junction of the left and right common iliac veins. The right common iliac artery passes in front of the left common iliac vein Variability of carotid bifurcation anatomy is a possible explanation. Flow models suggest that vessel anatomy, in particular vessel diameter and area ratios, affects plaque formation at arterial bifurcations. However, carotid bifurcation anatomy could only be a major risk factor for plaque formation if it was sufficiently variable. Since very few data exist on the extent of interindividual and intraindividual variability of bifurcation anatomy, we studied 5395 angiograms from the European. Development of dedicated quantitative bifurcation models could assist in: 1) understanding the relation between bifurcation anatomy and fractional flow reserve (FFR), a standard of reference for inducible myocardial ischemia (6); and 2) assessing interventional devices aiming at this complex clinical scenario Bifurcations are very common in blood vessels and in the bronchial 'tree' of the lungs. At a bifurcation the sum of the cross-sectional area of the two branches usually exceeds that of the parent branch. Since this happens many times, there is a progressive increase in the unit volume of the system

The carotid bifurcation is the point at which the common carotid artery terminates. As it does so, it forms the internal and external carotid arteries which go on to supply the head and neck. The height of the carotid bifurcation is noted to be highly variable in the literature. Most frequently the common carotid artery ascends until the level defined by the C4 vertebra posteriorly and upper border of thyroid cartilage anteriorly, where it enlarges into the carotid sinus before bifurcating. Consult this session to learn more about how to assess bifurcation anatomy as part of procedural planning, and discover a practical step-by-step algorithm for performing bifurcation PCI (provisional T, TAP, Culotte and DK crush) The radiologic anatomy of the aortic bifurcation in the rabbit has received little study but it is important as this anatomical area is widely used in atherosclerosis research. Thirty rabbits were used to study the aortic bifurcation and subsequent branching patterns on arteriography. Fifteen different arteries were identified. Mean arterial diameters of 2.88 ± 0.7 and 2.27 ± 0.55 mm were. The dark arrows represent projection vectors of the aneurysm, parent vessel, and branch vessels. The M1 vector originates at the internal carotid artery bifurcation and projects to the middle cerebral (MCA) bifurcation. The M2 branch projections represent the direction of these vessels as they originate from the MCA bifurcation. Sidewall aneurysms are those with a projection perpendicular to the direction of flow of the parent vessel Gross anatomy Segments. The MCA is divided into four segments: M1: sphenoidal or horizontal segment. originates at the terminal bifurcation of the internal carotid artery; courses laterally parallel to the sphenoid ridge; terminates either: at the genu adjacent to the limen insulae, where it makes a right angle turn 5; at the main bifurcation 6; M2: insular segment. originates at the genu.

The bifurcation anatomy and extent of disease are substantial determinants of bifurcation stenting strategies and clinical outcomes 5. Three-dimensional (3D) representation of the bifurcation.. • Knowledge of bifurcation anatomy is essential, yet available data are limited • The aim of this project is to create the world's first detailed statistical atlas of the anatomy of the coronary arteries in normal and diseased patients A major reason for the project was to generate anatomically correct bifurcation phantoms/models. Perhaps patient specific bifurcation stents will be 3D. Conclusions —Sex differences in carotid bifurcation anatomy are not limited to absolute vessel size. In addition, the outflow to inflow area ratio is bigger in women, and relative to the CCA and ECA, women have larger ICAs than men Bifurcation models are very useful for studies in which airway models with various shape are required to observe, for example, effect of bifurcation angle on flow dividing ratio, different flow patterns in successive airways depending on whether successive bifurcations are in the same plane or not, effect of carina shape on flow patterns, and particle deposition (Andrade et al., 1998.

19 Basilar Artery Bifurcation Aneurysms Microsurgical Anatomy. The basilar artery terminates in a quadrifurcation from which two posterior cerebral arteries (PCAs) and two superior cerebellar arteries (SCAs) originate . The P1 segment of the PCA begins at the basilar bifurcation and ends at the junction with the posterior communicating artery (PCoA). Thi Anatomy and Terminology. ICA bifurcation aneurysms arise at the distal end of the artery, and project as a direct extension of the terminal carotid flow towards and into the anterior perforated substance. Depending on the tortuosity of the vessel at this site, these aneurysms may point anterior-superiorly, directly superiorly, or posterior-superiorly, and may also be based more towards the anterior cerebral artery medially or the middle cerebral artery laterally. The lenticulo­striate.

Understanding the anatomy and physiology of coronary bifurcation lesion should be the most important step to this goal. The relationship of vessel diameter between branches and the anatomical and functional significance of plaque shift and carina shift are two most important concepts to understand. They are the science behind the predictors of SB occlusion, and the rationale of proximal optimization technique and final kissing ballooning. This specific review will be devoted to review those. Fig. 1 - Fractal anatomy of coronary artery bifurcation scheme. The mother vessel divides into two daughter vessels and the diameter of the mother vessel (D0) is greater than any of the two daughter vessel diameters (D1 and D2).

The elective treatment of bifurcation lesions with complex anatomy and diffuse atherosclerotic involvement of both the MV and the SB is more likely to require a two-stent approach. Two technical issues are critical in these patients. First, lesion preparation before stenting and, second, the procedure must involve KBI followed by final POT. Complete stent expansion facilitates optimal.

The Treatment of Bifurcation Disease is a challenging area in interventional cardiology. It presents a challenge as interventional cardiology takes on increasingly complex coronary cases. Studies report that when compared to non-bifurcation stenting, intervention to bifurcation disease is associated with lower rates of success, higher costs, longer hospitalisation and a higher rate of clinical.

The design of these dedicated bifurcation stents and balloons conforms to the natural anatomy of the bifurcation and can facilitate a more effective scaffolding of the SB ostium. Furthermore, these devices provide easier access to the main and side branch which lowers the risk of SB loss during the procedure. Several studies have shown that stenting of LM with these new-dedicated stents is. Double stenting techniques which are certainly more complex, time consuming & expensive than provisional stenting. None of the RCT's studies showed a clear advantage for routine double stenting over a provisional strategy. Other side of coin is patients with complex bifurcation anatomy such as large SBs with severe disease extending more than a few mm from the ostium were not well.

Anatomy of the internal carotid artery (anterior circulation) The common carotid artery divides at the level of the 4th cervical vertebra (C4) to form the ICA and external carotid artery.This site is referred to as the carotid bifurcation and contains the carotid body, which contains chemoreceptors that detect changes in the oxygen concentration and the pH-value of blood circulating through. The bifurcation can occur as high as the hyoid bone (Quain, 5/295; Poynter, 3/400) or even the styloid process, or as low as the cricoid cartilage (Quain, 10/295; Poynter, 18/400) or within 3.7 cm of its origin. The artery may not bifurcate but provide branches usually derived from the external carotid as it ascends in the neck. A common carotid artery may be absent, the external and internal. Coronary artery bifurcation lesions are markedly heterogeneous with regard to anatomy and the dynamic changes in anatomy that occur during treatment. The most suitable percutaneous coronary intervention strategy should be selected and optimized on an individual basis considering bifurcation characteristics that are known to influence the acute and long-term results Knowledge of carotid bifurcation (CB), common carotid artery (CCA) and its branches and their recognition during diagnostic imaging are also important for vascular surgical procedures in the region, such as carotid endarterectomy or radical neck dissection, catheterization and aneurysms. The surgical anatomy of the carotid arteries was studied in 20 cadavers. Micrometric values of the CB and.
