| right gastric vein | <anatomy, vein> It receives veins from both surfaces of the upper portion of the stomach, runs to the right along the lesser curvature of the stomach, and empties into the portal vein. Synonym: vena gastrica dextra, pyloric vein. (05 Mar 2000) |
|---|---|
| short gastric arteries | Four or five small arteries given off from the splenic, passing via the gastrosplenic ligament to the fundus of the stomach along the greater curvature, and anastomosing with the other arteries in that region. Synonym: arteriae gastricae breves, vasa brevia. (05 Mar 2000) |
| short gastric veins | Small vessels that drain the fundus and left portion of the stomach wall and empty into the splenic vein. Synonym: venae gastricae breves. (05 Mar 2000) |
| hyperplastic gastric polyp | <radiology> Regeneration polyp, inflammatory polyp, most common type of gastric polyp (75-90%), histology: proliferated gastric mucosa with acute and chronic inflammatory infiltrates in lamina propria, location: randomly distributed in stomach, associated with, chronic atrophic gastritis, pernicious anaemia, findings: sharply delineated polyp with smooth circular border, Mexican hat sign: stalk seen en face overlying the head of the polyp, sessile/pedunculate; usually multiple, usually less than 1 cm, no contour defect in stomach (12 Dec 1998) |
| sphincter of gastric antrum | Angular sphincter, thickening of the circular muscular layer forming a proposed intermediate sphincter at the level of the angular notch of the stomach. While the thickening of the circular muscle may indicate the commencement of the pyloric antrum, true functional sphincteric activity distinct from the other peristaltic contractions of the stomach is not observed although some of these may in fact temporarily close off the antrum from the remainder of the stomach lumen. Synonym: antral sphincter, midgastric transverse sphincter, sphincter antri, sphincter intermedius, sphincter of antrum, sphincter of gastric antrum. (05 Mar 2000) |
| superior gastric lymph nodes | Nodes located along the left gastric artery and its branches; they are divided into paracardial, upper and lower groups. Synonym: nodi lymphatici gastrici sinistri, superior gastric lymph nodes. (05 Mar 2000) |
| delayed gastric emptying | <gastroenterology> A condition where there is delayed stomach emptying (due abnormal gastric motility), often see as a complication of diabetes mellitus. Risk factors include diabetes, systemic sclerosis, previous vagotomy, previous gastrectomy, viceral neuropathy and the use of anticholinergic medications. Symptoms include bloating, nausea, vomiting and constipation. Treatment include dietary modification and the use of cholinergic medications and metachlopromide. (27 Sep 1997) |
| oesophageal and gastric varices | Submucosal varices of the lower oesophagus or gastric fundus mucosa, frequently caused by the development of portal collateral vessels consequent to portal hypertension. (12 Dec 1998) |
| thickened gastric folds | <radiology> Hyperacidic state, peptic ulcer disease, Zollinger-Ellison syndrome, hypoproteinaemia, lymphoma, pseudolymphoma, eosinophilic gastroenteritis, varices, Menetrier disease, inflammatory bowel disease (UC and Crohn), TB, syphilis (12 Dec 1998) |
| ulcer, gastric | A hole in the lining of the stomach corroded by the acidic digestive juices which are secreted by the stomach cells. Ulcer formation is related to h. Pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium X-ray or endoscopy. Complications of ulcers include bleeding, perforation, and blockage of the stomach (gastric obstruction). (12 Dec 1998) |
| left gastric artery | <anatomy, artery> Origin, coeliac; distribution, cardia of stomach at lesser curvature, abdominal part of the oesophagus, and, frequently, a portion of the left lobe of the liver via an aberrant left hepatic branch; anastomoses, oesophageal, right gastric. Synonym: arteria gastrica sinistra, coronary artery. (05 Mar 2000) |
| left gastric lymph nodes | Nodes located along the left gastric artery and its branches; they are divided into paracardial, upper and lower groups. Synonym: nodi lymphatici gastrici sinistri, superior gastric lymph nodes. (05 Mar 2000) |
| left gastric vein | <anatomy, vein> Arises from a union of veins from both surfaces of the cardia of the stomach and an oesophageal tributary from the cardiac portion of the oesophagus; it runs in the lesser omentum and empties into the portal vein. See: oesophageal veins. Synonym: vena gastrica sinistra, coronary vein, vena coronaria ventriculi. (05 Mar 2000) |
| anterior auricular branches of superficial temporal artery | <anatomy, artery> Distribution, auricle, earlobe and external acoustic meatus. Synonym: rami auriculares anteriores arteriae temporalis superficialis. (05 Mar 2000) |
| anterior cutaneous branches of intercostal nerves | Medial mammary branches of anterior cutaneous branches of ventral primary rami of thoracic spinal nerves. See: medial mammary branches. (05 Mar 2000) |
