| left hepatic veins | Veins draining the lateral segments [II & III] of the left lobe of the liver which join to form a single or paired trunk of variable size which usually (90% of the time) merges with that formed by the middle hepatic veins prior to entering the terminal portion of the superior vena cava. Synonym: venae hepaticae sinistrae. (05 Mar 2000) |
|---|---|
| left inferior pulmonary vein | <anatomy, vein> The vein returning oxygenated blood from the inferior lobe of the left lung to the left atrium. Synonym: vena pulmonalis inferior sinistra. (05 Mar 2000) |
| left lobe | The left subdivision of several glands, e.g., prostate, thyroid, thymus. Synonym: lobus sinister. (05 Mar 2000) |
| left lobe of liver | It is separated from the right lobe above and in front by the falciform ligament, and from the quadrate and caudate lobes by the fissure for the ligamentum teres and the fissure for the ligamentum venosum; the distribution of the portal vein, hepatic artery, and bile ducts does not correspond to the gross lobar divisions of the liver. It contains two segments, superior and inferior. Synonym: lobus hepatis sinister. (05 Mar 2000) |
| left lumbar lymph nodes | The chain of lymph nodes associated with the aorta in the abdomen; it is divided into three groups: lateral aortic lymph nodes on the left of the aorta; pre-aortic lymph nodes in front of the aorta; post-aortic lymph nodes, behind the aorta. Synonym: nodi lymphatici lumbales sinistri, lumbar lymph nodes. (05 Mar 2000) |
| left lung segments | <radiology> Upper lobe, apical posterior, anterior, superior lingular, inferior lingular, lower lobe, superior, posterior basal, lateral basal, anterior medial basal (12 Dec 1998) |
| left main bronchus | It arises at the bifurcation of the trachea, passes in front of the oesophagus and enters the hilum of the left lung where it divides into a superior lobe bronchus and an inferior lobe bronchus. It is longer, of narrower caliber, and more nearly-horizontal than the right main bronchus, hence, aspirated objects enter it less frequently. Synonym: bronchus principalis sinister. (05 Mar 2000) |
| left ovarian vein | <anatomy, vein> Begins as the pampiniform plexus at the hilum of the ovary and empties into the left renal vein. Synonym: vena ovarica sinistra. (05 Mar 2000) |
| left sagittal fissure | A sagittal groove on the undersurface of the liver formed by the fissura ligamenti teretis anteriorly and the fissura ligamenti venosi posteriorly. (05 Mar 2000) |
| left-sided appendicitis | Appendicitis occurring on the left side of the abdomen, usually the left-lower quadrant, due to abnormal rotation of the gut (such as situs inversus). (05 Mar 2000) |
| left-sided heart failure | Inability of the left heart to maintain its circulatory load with corresponding rise in pressure in the pulmonary circulation usually with pulmonary congestion and ultimately pulmonary oedema. (05 Mar 2000) |
| left-sidedness | The normal left-sided location of certain unpaired organs, such as the spleen and most of the stomach. (05 Mar 2000) |
| left superior intercostal vein | <anatomy, vein> The vein formed by the union of the left second, third, and fourth intercostal veins; it passes forward across the arch of the aorta to empty into the left brachiocephalic vein and frequently communicates also with the accessory hemiazygos vein. Synonym: vena intercostalis superior sinistra. (05 Mar 2000) |
| left superior pulmonary vein | The vein returning oxygenated blood from the left superior lobe of the lung to the left atrium. Synonym: vena pulmonalis superior sinistra. (05 Mar 2000) |
| left suprarenal vein | <anatomy, vein> The vein from the hilum of the left suprarenal gland that passes downward to open into the left renal vein; it usually is joined by the left inferior phrenic vein. Synonym: vena suprarenalis sinistra. (05 Mar 2000) |
