Those at high risk for this condition include patients with HYPERTENSION; DIABETES MELLITUS; ATHEROSCLEROSIS; and other CARDIOVASCULAR DISEASES.Posterior Cerebral Artery: Artery formed by the bifurcation of the BASILAR ARTERY. Branches of the posterior cerebral artery supply portions of the OCCIPITAL LOBE; PARIETAL LOBE; inferior temporal gyrus, brainstem, and CHOROID PLEXUS.Venous Thrombosis: The formation or presence of a blood clot (THROMBUS) within a vein.Posterior Cruciate Ligament: A strong ligament of the knee that originates from the anterolateral surface of the medial condyle of the femur, passes posteriorly and inferiorly between the condyles, and attaches to the posterior intercondylar area of the tibia.Phlebography: Radiographic visualization or recording of a vein after the injection of contrast medium.Venous Insufficiency: Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Uveitis, Posterior: Inflammation of the choroid as well as the retina and vitreous body. Some form of visual disturbance is usually present. The most important characteristics of posterior uveitis are vitreous opacities, choroiditis, and chorioretinitis.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Vena Cava, Inferior: The venous trunk which receives blood from the lower extremities and from the pelvic and abdominal organs.Hypothalamus, Posterior: The part of the hypothalamus posterior to the middle region consisting of several nuclei including the medial maxillary nucleus, lateral mammillary nucleus, and posterior hypothalamic nucleus (posterior hypothalamic area). The posterior hypothalamic area is concerned with control of sympathetic responses and is sensitive to conditions of decreasing temperature and controls the mechanisms for the conservation and increased production of heat.Graft Occlusion, Vascular: Obstruction of flow in biological or prosthetic vascular grafts.Ossification of Posterior Longitudinal Ligament: A calcification of the posterior longitudinal ligament of the spinal column, usually at the level of the cervical spine. It is often associated with anterior ankylosing hyperostosis.Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Vascular Patency: The degree to which BLOOD VESSELS are not blocked or obstructed.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Human Umbilical Vein Endothelial Cells: Endothelial cells that line venous vessels of the UMBILICAL CORD.Thrombophlebitis: Inflammation of a vein associated with a blood clot (THROMBUS).Vascular Surgical Procedures: Operative procedures for the treatment of vascular disorders.Spinal Fusion: Operative immobilization or ankylosis of two or more vertebrae by fusion of the vertebral bodies with a short bone graft or often with diskectomy or laminectomy. (From Blauvelt & Nelson, A Manual of Orthopaedic Terminology, 5th ed, p236; Dorland, 28th ed)Postoperative Complications: Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.Pituitary Gland, Posterior: Neural tissue of the pituitary gland, also known as the neurohypophysis. It consists of the distal AXONS of neurons that produce VASOPRESSIN and OXYTOCIN in the SUPRAOPTIC NUCLEUS and the PARAVENTRICULAR NUCLEUS. These axons travel down through the MEDIAN EMINENCE, the hypothalamic infundibulum of the PITUITARY STALK, to the posterior lobe of the pituitary gland.Follow-Up Studies: Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.Retrospective Studies: Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.Lens Capsule, Crystalline: The thin noncellular outer covering of the CRYSTALLINE LENS composed mainly of COLLAGEN TYPE IV and GLYCOSAMINOGLYCANS. It is secreted by the embryonic anterior and posterior epithelium. The embryonic posterior epithelium later disappears.Catheter Ablation: Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter.

Included are axial patterning, segmentation, compartment specification, limb position, organ boundary patterning, blood vessel patterning, etc.Infratentorial Neoplasms: Intracranial tumors originating in the region of the brain inferior to the tentorium cerebelli, which contains the cerebellum, fourth ventricle, cerebellopontine angle, brain stem, and related structures. Primary tumors of this region are more frequent in children, and may present with ATAXIA; CRANIAL NERVE DISEASES; vomiting; HEADACHE; HYDROCEPHALUS; or other signs of neurologic dysfunction. Relatively frequent histologic subtypes include TERATOMA; MEDULLOBLASTOMA; GLIOBLASTOMA; ASTROCYTOMA; EPENDYMOMA; CRANIOPHARYNGIOMA; and choroid plexus papilloma (PAPILLOMA, CHOROID PLEXUS).Venous Pressure: The blood pressure in the VEINS. It is usually measured to assess the filling PRESSURE to the HEART VENTRICLE.Posterior Capsule of the Lens: The posterior aspect of the casing that surrounds the natural CRYSTALLINE LENS.Anastomosis, Surgical: Surgical union or shunt between ducts, tubes or vessels. It may be end-to-end, end-to-side, side-to-end, or side-to-side.Parietal Lobe: Upper central part of the cerebral hemisphere.

The testicular vein (or spermatic vein), the male gonadal vein, carries deoxygenated blood from its corresponding testis to the inferior vena cava or one of its tributaries. It is the male equivalent of the ovarian vein, and is the venous counterpart of the testicular artery. It is a paired vein, with one supplying each testis: the right testicular vein generally joins the inferior vena cava; the left testicular vein, unlike the right one, joins the left renal vein instead of the inferior vena cava. The veins emerge from the back of the testis, and receive tributaries from the epididymis; they unite and form a convoluted plexus, called the pampiniform plexus, which constitutes the greater mass of the ...
A deep vein is a vein that is deep in the body. This contrasts with superficial veins that are close to the body's surface. Deep veins are almost always beside an artery with the same name (e.g. the femoral vein is beside the femoral artery). Collectively, they carry the vast majority of the blood. Occlusion of a deep vein can be life-threatening and is most often caused by thrombosis. Occlusion of a deep vein by thrombosis is called deep vein thrombosis. Because of their location deep within the body, operation on these veins can be difficult. Internal jugular vein Brachial vein Axillary vein Subclavian ...
In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor canal (also known as Hunter's canal) and is a continuation of the popliteal vein. It ends at the inferior margin of the inguinal ligament, where it becomes the external iliac vein. Several large veins drain into the femoral vein: popliteal vein deep vein of the thigh great saphenous vein Occlusion of the femoral vein can be life-threatening. The practice of delivering recreational drugs intravenously using the femoral vein is relatively common amongst injecting drug users (IDUs). The term superficial femoral ...
In human anatomy, the cephalic vein is a superficial vein in the arm. It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle. Near the shoulder, the cephalic vein passes between the deltoid and pectoralis major muscles (deltopectoral groove) and through the deltopectoral triangle, where it empties into the axillary vein. The cephalic vein is often visible through the skin, and its location in the deltopectoral groove is fairly consistent, making this site a good candidate for venous access. Permanent pacemaker leads are often placed in the cephalic vein in the deltopectoral groove. The ...
The great cerebral vein is one of the large blood vessels in the skull draining the cerebrum of the brain. It is also known as the "vein of Galen", named for its discoverer, the Greek physician Galen. However, it is not the only vein with this eponym.[clarification needed] The great cerebral vein is considered as one of the deep cerebral veins. Other deep cerebral veins are the internal cerebral veins, formed by the union of the superior thalamostriate vein and the superior choroid vein at the interventricular foramina. The internal cerebral veins can be seen on the superior surfaces of the caudate nuclei and thalami just under the corpus callosum. The ...
The vertebral vein is formed in the suboccipital triangle, from numerous small tributaries which spring from the internal vertebral venous plexuses and issue from the vertebral canal above the posterior arch of the atlas. They unite with small veins from the deep muscles at the upper part of the back of the neck, and form a vessel which enters the foramen in the transverse process of the atlas, and descends, forming a dense plexus around the vertebral artery, in the canal formed by the foramina transversaria of the cervical vertebrae. This plexus ends in a single trunk, which emerges from the foramen transversarium of the sixth cervical vertebra, and opens at the root of the neck into the back part of the innominate vein near its origin, its mouth being guarded by a pair of valves. On the right side, it crosses the first part of the subclavian artery. Section of the neck at about the level ...
The supraorbital vein begins on the forehead where it communicates with the frontal branch of the superficial temporal vein. It runs downward superficial to the Frontalis muscle, and joins the frontal vein at the medial angle of the orbit to form the angular vein. Previous to its junction with the frontal vein, it sends through the supraorbital notch into the orbit a branch which communicates with the ophthalmic vein; as this vessel passes through the notch, it receives the frontal diploic vein through a foramen at the bottom of the notch. The areas drained by this vessel are the forehead, eyebrow and upper eyelid. Bloodvessels of the eyelids, front view. Lateral head anatomy detail Head anatomy anterior view This article incorporates text in the public ...
A peripheral cannula is the most common intravenous access method utilized in both hospitals and pre-hospital services. A peripheral IV line (PVC or PIV) consists of a short catheter (a few centimeters long) inserted through the skin into a peripheral vein (any vein not situated in the chest or abdomen). This is usually in the form of a cannula-over-needle device, in which a flexible plastic cannula comes mounted over a metal trocar. Once the tip of the needle and cannula are introduced into the vein via venipuncture, the cannula is advanced inside the vein over the trocar to the appropriate position and secured, the trocar is then withdrawn and discarded. Blood samples may be drawn directly after the initial IV cannula insertion. Any accessible vein can be used although arm and hand veins are used most ...
The circulatory system uses the channel of blood vessels to deliver blood to all parts of the body. This is a result of the left and right side of the heart working together to allow blood to flow continuously to the lungs and other parts of the body. Oxygen poor blood enters the right side of the heart through two large veins. Oxygen rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs. This is also the site where carbon dioxide exits the blood. This all occurs in the lungs where blood is oxygenated.[6]. The blood pressure in blood vessels is traditionally expressed in millimetres of mercury (1 mmHg = 133 Pa). In the arterial system, this is usually around 120 mmHg systolic (high pressure wave due to contraction of the heart) and 80 mmHg ...
... is on the northwestern side of the Net Lake-Vermilion Lake Deformation Zone. This is a northeast-southwest trending high strain zone that separates rocks of the Older and Younger volcanic complexes, which in turn comprise the Temagami Greenstone Belt.[1]. Reserves at Hermiston-McCauley have been variously estimated at 31,000 tons averaging 0.275 oz (7.8 g) of gold per ton, 45,700 tons averaging 0.30 oz (8.5 g) of gold per ton over 1 m (3.3 ft), or 9,000 tons averaging 0.5 oz (14 g) of gold per ton over 0.91 m (3.0 ft). A main and subsidiary quartz-rich zone occur in a ruptured diorite intrusion, which intrudes felsic volcanic rocks in a northwesterly direction with the strike of the Net Lake-Vermilion Lake Deformation Zone. The main quartz vein is at least 76.1 m (250 ft) long and up to 1.5 m (4.9 ft) wide. Pyrite with chalcopyrite and gold occupies quartz veins as blebs and small veins.[1]. ...
Electrical sockets supply a flow of current which comes out of one pin of a socket, called "Live", runs through an electrical device, and returns through the other pin "Neutral." In many countries, such as USA, India and others, the "Neutral" is also connected to the earth (via a rod driven into the soil). If a person touches a bare "live" wire, current can travel through the body to any part (like another hand or the bare feet) connected directly or indirectly to the earth, such as through metal such as plumbing pipes or through moist tiles or a bathtub full of water where the water acts as a conductor. Pure water is a poor conductor but in the kitchen or bathroom it is usually salty or soapy which increases the conductivity; but no matter, since it takes so little current to kill a person, even a poor conductor can result in a lethal shock. The GFCI device uses a differential transformer to compare the current "going out" on the hot leg with the current "coming back in" on the neutral. If ...
