In contrast, other veins may form in one step by larger scale breakage of the host rock and one-stage infill of this fracture. The veins are often only a metre or two wide. Aliasing of flow was seen from the left pulmonary veins entering the left atrium, suggesting obstruction. She was anxious starting new things and so somatic that if one touched her arm, she would complain that her veins hurt. The pulmonary veins connect to the leftsided atrium. The right atrium received the systemic veins and was displaced posteriorly by the mediastinal "mass", which was the pulmonary trunk. The symptomatology does not differ between atresia of solitary or individual pulmonary veins. The atrium receiving the systemic veins appeared to be a solitary chamber, connected with the large morphologically right ventricle via a wide tricuspid valve. The left pulmonary veins proved to be absent. The left atrium received all four pulmonary veins, the wall was hypertrophied and the chamber dilated. The aorta, pulmonary trunk and the major veins were all normal. The prognosis is uniformly poor, despite surgery and attempted balloon dilation of the narrowed veins. At operation, severe obstruction at the site of entry of the pulmonary veins into the left atrium was found, more marked on the right side. Wandering inversions of venous flow were observed in bridging veins between neighboring systems of drainage during low-flow perfusion. Physical markers of collagen abnormalities include development of hernia, striae, varicose veins, haemorrhoids and joint hypermobility. During cardiac catheterization, anomalous drainage of the pulmonary veins was excluded by right ventricular and, if necessary, by selective pulmonary angiography. The distances to the right pulmonary veins, the mitral valve and the coronary sinus were measured. The pulmonary veins, left atrium and aortic arch are clearly seen. Blood was taken from ear veins 10 days after the final injection. During cardiac catheterization it was documented that both femoral veins were obstructed with no reconstitution of the caval venous system until the renal veins. Injections into each of the pulmonary veins revealed tight stenoses of all veins at the veno-atrial junction, especially the right upper and middle pulmonary veins. The atriums were of usual morphology ("solitus") and received normally connected systemic and pulmonary veins. The rightsided pulmonary veins drained into the right-sided atrium and the left-sided pulmonary veins into the leftsided atrium. Cardiopulmonary bypass is commenced, and snares are placed around the caval veins. Wing fringes distinctly smoky grey; some of the hairs on the veins are also dark grey or smoky grey. All right and the left lower pulmonary veins connected to the right-sided atrium. Therefore, the study was interpreted as positive for pulmonary arteriovenous fistulas whenever echo contrast was seen to fill the left atrium from the pulmonary veins. The rightsided atrium received normally connected systemic veins. The pulmonary veins appeared to be draining normally. Cardiopulmonary bypass is established between cannulas placed in the ascending aorta and both caval veins. Undeformed, cross-cutting stilpnomelane veins, in places altered to chlorite, are characteristic of the contact zone. The clast infill of the veins always closely matches the wallrock. However, we interpret the veins to be a product of extensional deformation and fluid flow, rather than a sedimentary feature. Samples were carefully selected to avoid the effects of veining or fracturing. After formation, the veins evolve as thermodynamically closed systems. The development of veins is likely to have a pronounced effect on the mechanical behaviour of the fault zones. The clay contains a large number of contorted calcite veins. Earlier fabrics, cross-cut by the veins, are more ductile in nature and may reflect the aseismic stage of the fault history. Both veins and stems show fine longitudinal striae, probably representing the lignified vascular fibres. Along the veins, the cells are elongate, up to c. 100 m long and 20 m wide. Measurements were made of bore and medial thickness of the pulmonary veins. The leaves had 20-25 secondary veins of which an average of 16 were cut. The saphenous veins were cannulated and surgery continued under thiopental sodium anesthesia. A variably veined suboceanic upper mantle-genetic significance for mid-ocean ridge basalts from geochemical evidence. Will the rise of multimedia performance (including live video mixes by vj's) in popular music veins have a positive effect on such output? Footwall turbidites are generally unaffected except for localized cataclasis and veining within a few centimetres of the actual fault. The scarce seromuscular tunic of the vesical placental vessels often makes them go unnoticed during the pulling manoeuvres, since they collapse as veins. Cerebral atrophy increases the vulnerability of bridging veins to shearing forces and so the elderly are more susceptible. Embolization or ligation of internal iliac artery or bilateral mass ligation of uterine arteries and veins should be considered. A cork borer was used to remove five discs from each leaf, avoiding areas with large veins. In these veins, very high degrees of fractional crystallization are reached, producing interstitial silica-rich glasses. Where the inclusions occur along rehealed fractures, they are secondary with respect to the quartz veins, but represent the ambient fluid during the brecciation process. Later fractures are represented by bands of undeformed quartz that cut across the veins with undulose extinction and represent infill of dilational fractures. In specific instances, more leukocytic infiltrate was localized around altered venous branches than arterial branches, although both veins and arteries were involved. As the lungs move cephalad, the orifices of the pulmonary veins migrate upwards and laterally, retaining their direct connection to the left atrium. The movement lasted officially just one year, from 1968 to 1969, but its practitioners continued experimenting in similarly audacious veins for some years. Septarian cracks filled with later chert veins transect the nodules. The basement is cross-cut by tightly folded quartz-sulphide veins. The rock has developed a cataclastic fabric and is cut by several generations of cross-cutting pseudotachylite veins. No suturing is necessary at its base, that is, the site of entrance of the right pulmonary veins. One pair of wings from each specimen used in the morphometric study was slide mounted so that veins could be measured accurately. In contrast, the reduced pulsatility of the hepatic veins documented in patients after total cavalpulmonary anastomosis was thought to protect liver function. There was, in addition, totally anomalous pulmonary venous connection with all pulmonary veins connecting to the right-sided atrium. There was some intimal fibrosis of the pulmonary veins. The device can then be visualised relative to the atrial septum, the right pulmonary veins, and the mitral valve. In the dark areas the membrane is brown, being darker near the veins, and the veins themselves are dark brown or black. The dark colouring of the wing-pad veins is the most fugitive. The aetiology is thought to be due either to previous deep venous thrombosis or to incompetence of the superficial or communicating veins. Occasional worms covered by blood were detected in the septal hepatic veins. All the microbial mats observed, from shallow water to (partially) subaerial environments, occur in intimate association with hydrothermal veins and vents. Distended neck veins and hepatomegaly of four cm were noted. Brief periods of total circulatory arrest were necessary to obtain adequate visualization of the hepatic veins. They underwent further surgery to convert the atrio-pulmonary to a cavo-pulmonary anastomosis which excluded all the hepatic veins. Distended neck veins and peripheral cyanosis were noted. Within 3 weeks, there was evidence of bilateral stenosis of the pulmonary veins at the anastomosis, associated with elevated wedge pressure. There was no hepatomegaly, and the dimensions of the superior and inferior caval veins, and the right atrium were within normal limits. All patients had attachments of the valvar membrane at the orifices of both the inferior and superior caval veins. Angiography should also assess the infradiaphragmatic systemic veins. All the reconstructed arteries showed patency; meanwhile 50% of the jugular veins were thrombosed. During the last few years, he has had recurrent admissions to hospital for pleural effusions, ascites, edema and distention of the head and neck veins. All biopsies showed arterialization of the small veins. The whole repair is almost always performed on full cardiopulmonary by pass using the right angle metal cannulas inserted directly in the caval veins. The pulmonary veins were connected to the left atrium, with normal connections of the superior and inferior caval veins to the right atrium. At six weeks of gestation, she was cyanosed with mild digital clubbing, slight engorgement of the neck veins, but no dyspnea at rest. One cavity received the caval veins; the other contained the coronary sinus and the tricuspid valve. The right middle, left upper and left middle pulmonary veins were small and stenosed at their insertion into the left atrium. The balloon was not seen to enter the left pulmonary veins. Meticulous elimination of collateral arteries in the preoperative setting facilitates the operation by reducing the amount of flow in the pulmonary arteries and veins. The pulmonary veins returned into an effectively common atrium and there was no evidence of pulmonary venous obstruction. The pulmonary veins were connected to the right-sided atrium, and there was a restrictive atrial septal defect. Intimal abnormalities were not seen in the veins in any of the cases. The intensity of this veining adjacent to the fault is such that the veins comprise more than 50 % of the rock volume. Deformation produced progressive work hardening of the quartz veins. The polyphase nature of this veining is confirmed by the fact that many of the veins are folded and then cross-cut by later, undeformed, veins. In the smaller pinnules, the veins radiate from the base. In the larger, more lobed pinnules there is a midvein from which lateral veins are produced. Extension in this orientation would reactivate pre-existing structures, such as metamorphic quartz veins, with a component of sinistral shear. Venation is dichotomous, with the distal veins curved away from the midline of the leaf towards the margins. Closer to the thrust surface the shale becomes highly quartz veined.
