左头臂静脉与冠状窦异常交通1例   总被引:1,自引:0,他引:1  
作者在对一成年男尸解剖时,发现其左头臂静脉与冠状窦之间存在交通静脉(附图)。报告如下:该交通静脉起自左头臂静脉始端下壁,经主动脉弓左前方,左肺动脉始端之前,穿心包注入冠状窦。长9cm,外径5mm,行程较直,内有凝血。头臂静脉与冠状窦之间存在交通静脉极为罕见。因异常交通静脉的存在,增大了冠状窦的静脉压,减小了冠状窦与其细小属支之间的压力差,冠脉回流速度减慢。可导致心脏静脉系统淤血,冠状动脉血流阻力增大,血流量减少。影响心脏的泵血功能,特别是在剧烈运动时可能会产生严重后果。在心脏外科手术时,阻断血流…  相似文献

冠状窦及其属支是心静脉系的主要组成部分,回流整个心脏的60%静脉血,最后经冠状窦口汇入右心房。关于这方面的国人体质资料不多,仅金崇厚、毕建础等及石中梁作过一些调查。为了积累资料,更正确地反映冠状窦及其属支的形态,作者进行了本工作。共解剖经固定的50例或人心脏,绝大多数为男性。先测量冠状窦的长度及管径,观察其属支的数目、起始、走行及注入等。然后纵行切开冠状窦及其主要属支的管壁,检查其瓣膜及开口等。  相似文献

The anatomy of the coronary sinus and its tributaries   总被引:4,自引:0,他引:4  
The coronary sinus and its tributaries were studied by anatomical dissection in 37 adult human cadaveric hearts, which had been fixed in formalin solution. An anastomosis of approximately 1.0mm in calibre was observed between the anterior and posterior interventricular veins in 19% of specimens. Myocardial bridges were detected above the anterior interventricular vein or its tributaries in 8% of specimens. The great cardiac vein formed the base of the arteriovenous trigone of Brocq and Mouchet with the bifurcating branches of the left coronary artery in 89% of specimens and formed an angle accompanying these arterial branches in 11%. In the trigone the anterior interventricular and great cardiac veins were superficial to the arteries in 73% of specimens. The left marginal vein was present in 97% of specimens, emptying into the great cardiac vein in 81% of cases and into the coronary sinus in the remaining 19%. The small cardiac vein was present in 54% of specimens. In the coronary sulcus the great cardiac vein was adjacent to the circumflex branch of the left coronary artery in 76% of specimens and to the right coronary artery in 5% in 19% there was no relationship with either artery. The coronary sinus maintained a relationship with the right coronary artery in 46% of specimens and with the left coronary artery in 32% in 22% it had no relationship with these vessels.  相似文献

The objective of this study was to quantitatively characterize anatomy of the human phrenic nerve in relation to the coronary venous system, to reduce undesired phrenic nerve stimulation during left‐sided lead implantations. We obtained CT scans while injecting contrast into coronary veins of 15 perfusion‐fixed human heart‐lung blocs. A radiopaque wire was glued to the phrenic nerve under CT, then we created three‐dimensional models of anatomy and measured anatomical parameters. The left phrenic nerve typically coursed over the basal region of the anterior interventricular vein, mid region of left marginal veins, and apical region of inferior and middle cardiac veins. There was large variation associated with the average angle between nerve and veins. Average angle across all coronary sinus tributaries was fairly consistent (101.3°–111.1°). The phrenic nerve coursed closest to the middle cardiac vein and left marginal veins. The phrenic nerve overlapped a left marginal vein in >50% of specimens. Clin.

Intersection patterns of human coronary veins and arteries   总被引:1,自引:1,他引:0  
Intersections between the coronary veins (CV) and arteries (CA) of 103 adult human hearts were mapped on the heart surface. Then the correlations of these intersection patterns to their localization were studied. Eight spots were selected where one of four major CV (anterior cardiac vein, middle cardiac vein, left posterior ventricular vein, and great cardiac vein) intersected with one of CA and their branches (right coronary artery, posterior interventricular branch, left posterior ventricular branch, circumflex branch, diagonal branch, and anterior interventricular branch). The great cardiac vein (GCV) ran beneath the anterior interventricular branch in 56 specimens out of 103, beneath the diagonal branch in 75 specimens out of 103, and beneath the circumflex branch in 36 specimens out of 103, while the other CV mostly ran over CA. The present observations suggest that the CV on the right side may be formed prior to CA, while the CV on the left side may be formed simultaneously with CA.  相似文献

Clinical anatomy of cardiac veins,Vv. cardiacae   总被引:3,自引:0,他引:3  
New methods of cardiological examination and treatment, such as catheterization and arterialization of the coronary sinus, venous reperfusion and cardioplegia have made necessary an exact account of the distribution pattern and the mode of opening of the cardiac veins. 350 hearts were prepared for examination with macroscopical techniques. There are three systems of the major cardiac veins: tributaries of the coronary sinus, anterior cardiac veins, atrial cardiac veins. Their openings lie in a circle-like arrangement between the ostia of both caval veins and just above the tricuspid valve. In most cases there are variably sized intramural collecting chambers or sinuses just before the opening of all the cardiac veins. These sinuses are interpreted to favour the return of cardiac venous bloodstream from the myocardium to the right atrial cavity. The tributaries of the coronary sinus and of the anterior cardiac veins are very variable. There is for instance only in 36% of cases a small cardiac vein, which belongs to the coronary sinus system. In 64% a small cardiac vein does not exist, but its origin, the right marginal vein, joins the system of anterior cardiac veins. This behaviour diminishes the function of the coronary sinus and increases the importance of the system of anterior cardiac veins. Intramural courses of the great cardiac vein, crossing coronary arteries, ostial valves of cardiac veins, ostial valve of coronary sinus and of inferior vena cava, ostial occlusion of coronary sinus, and aneurysm like excavation of the posterodorsal wall of the right atrium have been described also. These facts and structures may cause morphological hindrances fo catheterization of the right atrium and coronary sinus and for reperfusion of cardiac venous drainage pathways. This report about a large conus vein, which is a great cardiac vein joining anterior cardiac veins and about intramural courses of great cardiac vein as well as semicircular venous sinuses in the wall of the right atrium is the first in the literature.  相似文献

Vieussens valve (Vv) is the ostial valve of the great cardiac vein located near the beginning of the coronary sinus. Knowledge of its anatomy is important for several trans-sinus cardiologic procedures. The frequency of its presence is reported to vary from 65-87%. We documented the post mortem morphology of Vieussens valve in 50 unfixed, intact human coronary sinuses using endoscopy. We believe this is the first study of the anatomy of the coronary sinus and the adjacent venous ostia to employ this technique. Vieussens valve was observed in 78% of specimens. Special attention was given to the shape of the valve leaflets. Five morphological types of Vv were distinguished: single leaflet, flat (16%); single leaflet, concave (20%); double leaflet, flat (8%); double leaflet, concave (32%); and triple leaflet, concave (2%). We found post mortem endoscopy of the coronary sinus to be a good and reliable method of visualizing Vieussens valve.  相似文献

Anomalous venous system in the human heart   总被引:1,自引:1,他引:0  
In a 2002 cadaveric dissection course, a complex manner of rare variation was found in the abnormal venous system of the heart of an 88-year-old Japanese man who died of acute pneumonia. The superior vena cava and the left and right brachiocephalic veins were normal. In this case, a complex venous system existed as follows. (1) A left superior vena cava was persistent. (2) The innominate vein was present. It went upward between the ascending aorta and the pulmonary trunk, passed through the ventral side of the bifurcation of the pulmonary trunk, and then anastomosed with the left superior vena cava. The oblique vein of the left atrium, as a fibrous bundle, was connected to the junction of the left superior vena cava and the innominate vein in the pericardium. (3) The great cardiac vein was divided into two branches. One was located at the right side of the left coronary artery, forming the origin of the innominate vein. The other extended to the coronary sinus as a normal great cardiac vein. (4) The orifice of the coronary sinus on the right atrium was obliterated. (5) The abnormal orifice existed between the left atrium and the coronary sinus. The formation process and functional significance of such venous variations are discussed.  相似文献

The incidence and distribution of landmarks relating to the coronary sinus (c.s.) were evaluated in 240 human hearts. Special attention was directed to the myocardial coat of the c.s., the distribution and pattern of the cardiac veins, and their dimensions. In all specimens the myocardial coat of the c.s. also covered the adjacent 2 to 11 mm of the great cardiac vein. In 15% of cases this myocardial layer was thickened in a sphincter-like fashion, the edge of which was formed obliquely, in a crescent-like manner, or diffusely without a sharp border. In 3% of the hearts the myocardial cover of the c.s. extended over the terminal 10 mm of the middle cardiac vein as a strong fiber cord. In 9%, single isolated belts of fibers fixated the terminal parts of the adjoining cardiac veins to the posterior wall of the left atrium, and in 8% two or three myocardial cords, embedded in the fatty tissue of the left coronary sulcus, did the same. Because the myocardial cover extended leftwards to variable distances over the c.s., the left edge of the myocardial covering cannot serve to define the beginning of the coronary sinus. The location of the ostial valve of the great cardiac vein (valve of Vieussens) was variable as well, being found on the average 2.5 mm proximal to the opening of the oblique vein of the left atrium. Moreover, the valve of the great cardiac vein was found in only 87% of cases; therefore it is inappropriate for defining the beginning of the coronary sinus. Finally, the dot-like ostium of the oblique vein was most constant, and from the viewpoint of embryologic development, it is the logical landmark for determining the beginning of the coronary sinus, a necessary presupposition for cardiologic procedures like reperfusion of cardiac veins.  相似文献

There have been no anatomical reports on the origin of the bronchial artery derived from the coronary artery. In a 2006 cadaveric dissection course, an anomalous bronchial artery that reached the middle lobe of the right lung from the left coronary artery was observed in an 88-year-old Japanese man. In this specimen, the circumflex branch of the left coronary artery passed under the left auricle in the coronary sulcus and bifurcated to three branches (left marginal branch, posterior left ventricular branch, atrial branch), which were 3.2–3.4 mm in diameter. The atrial branch intersected on the surface of the great cardiac vein, ran along the oblique vein of the left atrium, and reached the atrial side of the transverse pericardial sinus, and then divided into two branches. One of them led to the right atrium. The other branch passed between two right superior pulmonary veins, which derived from superior and middle lobes of the right lung, respectively, through the hilum of the lung along the right superior pulmonary vein derived from the middle lobe, and finally became the bronchial artery in the middle lobe of the right lung. In the middle lobe, the bronchial artery divided into a thin branch along the pulmonary vein for the lateral segment, ran along the surface of the right middle bronchus, and then reached the medial segment, being wedged between the segmental bronchus and vein.  相似文献

An anatomical understanding of human coronary arterial and venous systems is necessary for device development and therapy applications that utilize these vessels. We investigated the unique use of contrast‐CT scans from perfusion‐fixed human hearts for three‐dimensional visualization and analysis of anatomical features of the coronary systems. The coronary arterial and venous systems of eleven perfusion‐fixed human hearts were modeled using contrast‐CT and Mimics software. The coronary arteries that coursed near the major coronary veins, how close coronary arteries were to coronary veins, and the size of adjacent coronary arteries were recorded and analyzed. The majority of coronary veins were within 5 mm of a coronary artery somewhere along its length. Interventricular veins elicited the largest occurrence of overlaps. There was significant variability in the percentage of each vein that coursed within 0.5, 1, 2, and 5 mm of a nearby artery. The left marginal veins and anterior interventricular vein had the largest portion of the vein that coursed near a coronary artery. The right coronary artery most often coursed near the middle cardiac vein. The inferior veins of the left ventricle elicited the most variation in adjacent arteries. The left circumflex artery and/or branches of the circumflex artery coursed near the left marginal vein in all cases where there was an artery near the marginal vein. The wide variation of measurements reinforces the importance of a precise understanding of individualized cardiac anatomy in order to provide the highest quality care to cardiac patients. Clin.
