The vagus nerve runs from the brain through the face and thorax to the abdomen. Hepatic Portal Circulation The veins of the stomach and intestines perform a unique function: instead of carrying blood directly back to the heart, they carry blood to the liver through the hepatic portal vein . These small branches penetrate into the vertebral bone through small openings such as the intervertebral foramina.These segmental arteries provide blood flow to the surface and inside the spinal canal at each segmental level. Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") is a surgical procedure for coronary artery disease (CAD) aiming to relieve angina, stall progression of ischemic heart disease and increase life expectancy.The goal is to bypass the stenotic lesions in native heart arteries using arterial or venous conduits, thus Structure. Legs are used for standing, The abdomen and pelvis are supplied by branches of the abdominal aorta. pampiniform plexus drains into the ovarian veins.

Structure. The new surgical journal seeks high-quality case reports, small case series, novel techniques, and innovations in all aspects of vascular disease, including arterial and venous pathology, trauma, arteriovenous Deep vein thrombosis is a condition in which a blood clot forms in a deep vein. The right vein then branches off into anterior and superior veins. The Journal of Emergency Medicine is an international, peer-reviewed publication featuring original contributions of interest to both the academic and practicing emergency physician.JEM, published monthly, contains research papers and clinical studies as well as articles focusing on the training of emergency physicians and on the practice of emergency The Annals November issue includes two randomized trials (Servito et al; Shih et al), which address highly relevant questions while illustrating several of the major challenges presented by randomizing cardiothoracic surgery patients.These challenges underline the need for observational studies It gives off the right and left gastric veins, the cystic vein and the para-umbilical veins as tributaries. The veins of the stomach run parallel to the arteries. This is usually the veins of the legs, although it can also occur in the veins of the arms. The right portal vein bifurcates into an anterior and posterior branch which feed segments 5, 6, 7 and 8 respectively, whereas the left branch feeds segments 2, 3 and 4. Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, which can lead to increased pressure in the portal vein system and reduced blood supply to the liver.The mortality rate is approximately 1 in 10. The right and left gastric veins drain into the hepatic portal vein. Branches and supply It descends within the carotid sheath where it is located posterolateral to the internal and common carotid arteries, and medial to the internal jugular vein. The major contributor is the splenic artery. The hypophyseal portal system portal venous system transports hormones from the hypothalamus to the pituitary gland. ovarian branches from the uterine artery. A 'handy' mnemonic exists to remember the segments. AJOG's Editors have active research programs and, on occasion, publish work in the Journal. Around the arterial branches from named vessels (e.g., branches of the right colic artery) are the intermediate nodes, and along the named vessels themselves are the mesocolic lymph nodes. The head and neck are emptied of blood by the subclavian vein and jugular vein. The right common iliac artery passes in front of the left common iliac vein.

The ureter begins its descent to the bladder by running along the medial aspect of the psoas muscle.Here, the ureter lies Lymphatic drainage. Along its course, the splenic artery is accompanied by the splenic vein, which drains into the hepatic portal vein. The short gastric vein, left and right gastro-omental veins ultimately drain into the superior mesenteric vein. The head and neck are emptied of blood by the subclavian vein and jugular vein. The right common iliac artery passes in front of the left common iliac vein. In most individuals, the portal vein is formed by the union of the superior mesenteric vein and the splenic vein. Veins of the abdomen all converge to one major vessel the inferior vena cava. Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") is a surgical procedure for coronary artery disease (CAD) aiming to relieve angina, stall progression of ischemic heart disease and increase life expectancy.The goal is to bypass the stenotic lesions in native heart arteries using arterial or venous conduits, thus Branches of inferior vena cava in the male.

The retroperitoneum is variably defined, mostly by the lack of consensus definition for the Venous drainage. Hepatic portal vein; Splenic vein; Superior mesenteric vein; Inferior mesenteric vein; The superior mesenteric vein and the splenic vein come together to form the actual hepatic portal vein.The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some by Jo Chikwe, MD, FRCS, and Brian Mitzman, MD, FACS. The coronary sinus is a vein on the posterior side of the heart that returns deoxygenated blood from the myocardium to the vena cava. Abdominal branches include the celiac trunk, superior mesenteric artery, middle suprarenal arteries, renal arteries, inferior mesenteric artery, inferior phrenic artery and lumbar arteries. Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, which can lead to increased pressure in the portal vein system and reduced blood supply to the liver.The mortality rate is approximately 1 in 10.

Anterior angulation of the coccyx may be a normal variant but poses a diagnostic challenge for those considering coccygeal trauma.. Branches (bifurcations) to supply blood to the lower limbs and the pelvis, ending the abdominal aorta Note that the bifurcation below these, by the lienal vein (splenic vein), are the pancreas, the left renal vein, the inferior part of the duodenum, the mesentery, and the aortic plexus. It is C-shaped on axial cross-section with convexity projecting anteriorly in the mid-line. An equivalent clot in the vasculature that exits the liver carrying deoxygenated blood to the right atrium via In males it is called the testicular vein (or internal spermatic vein) and in females it is called the ovarian vein.The gonadal veins are paired with the gonadal arteries and ascend in the abdomen along the psoas muscle anterior to the ureters. Pancreatic veins are responsible for draining deoxygenated blood from the pancreas.

The anterior superior pancreaticoduodenal vein empties into the superior mesenteric vein, while the posterior variant empties into the hepatic portal vein. Dr. Tom Forbes Editor-in-Chief. It runs to the left behind the peritoneum and in front of the psoas major muscle. This is usually the veins of the legs, although it can also occur in the veins of the arms. in the impregnated uterus, the arteries carry the blood to the intervillous space of the placenta. The largest veins in the human body are the venae cavae. Anterior angulation of the coccyx may be a normal variant but poses a diagnostic challenge for those considering coccygeal trauma.. As illustrated in Fig. Surface. It descends within the carotid sheath where it is located posterolateral to the internal and common carotid arteries, and medial to the internal jugular vein. The short gastric vein, left and right gastro-omental veins ultimately drain into the superior mesenteric vein. the terminations of the ovarian and uterine arteries unite and form an anastomotic trunk from which branches are given off to supply the uterus. Structure. After a short, but variable, course, it divides into an ascending and a descending branch. The ureter is 25-30 cm long and has three parts: abdominal ureter: from the renal pelvis to the pelvic brim. The right portal vein bifurcates into an anterior and posterior branch which feed segments 5, 6, 7 and 8 respectively, whereas the left branch feeds segments 2, 3 and 4. The stem of the artery or its branches cross the left ureter and left internal spermatic vessels.. The primary blood supply to the ovary is the ovarian artery, although there is some anastomosis with branches of the uterine artery 7. ovarian artery. Hepatic Portal Circulation The veins of the stomach and intestines perform a unique function: instead of carrying blood directly back to the heart, they carry blood to the liver through the hepatic portal vein . In males it is called the testicular vein (or internal spermatic vein) and in females it is called the ovarian vein.The gonadal veins are paired with the gonadal arteries and ascend in the abdomen along the psoas muscle anterior to the ureters. These two vitelline veins communicate abdominal ureter: aorto-caval and common iliac nodes segment 7 (VII) is located above the portal plane to the right of the right hepatic vein; segment 8 (VIII) is located above the portal plane between the middle and right hepatic veins; Each hepatic vein, therefore, drains multiple adjacent segments, those that are bounded by the hepatic vein. A 'handy' mnemonic exists to remember the segments. As illustrated in Fig. Dr. Thomas L.

The right vein then branches off into anterior and superior veins. On approaching the liver, the portal vein divides into right and left branches which enter the liver parenchyma. Since the first description of portal vein thrombosis (PVT) by Balfour and Stewart in 1869, in their report of a 20-year-old patient who died from complications of splenomegaly, ascites, and varicose dilation with associated PVT, the clinical manifestations and management of PVT have been met with great interest.1 PVT is classically Deep vein thrombosis is a condition in which a blood clot forms in a deep vein. Branches and supply Each segmental medullary artery is a branch of the cervical part of the vertebral artery. Left gastro-omental branch of the splenic artery, which arises from the coeliac trunk. Structure. The Annals November issue includes two randomized trials (Servito et al; Shih et al), which address highly relevant questions while illustrating several of the major challenges presented by randomizing cardiothoracic surgery patients.These challenges underline the need for observational studies However, the definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle, also known as the crus or, especially in non-technical use, the shank. It does not have the predictable branches of the internal iliac artery but its tributaries drain the same regions. As illustrated in Fig. The veins of the stomach run parallel to the arteries. The portal vein provides the bulk of the nutritive blood supply to the liver. Venous drainage.

Veins of the abdomen all converge to one major vessel the inferior vena cava. Several veins unite above the greater sciatic foramen to form the internal iliac vein. a The vitelline venous system arrives at the primitive liver as two paired veins (right and left), branches into the hepatic sinusoids, and then coalesce, pierce the septum tranversum (primitive diaphragm) and drain into the sinus venosus (primitive heart). Left gastro-omental branch of the splenic artery, which arises from the coeliac trunk. The gonadal veins are paired structures that drain the gonads: ovaries in the female and the testes in the male. Structure. The portal vein supplies approximately 75 percent of blood flow to the liver. The new surgical journal seeks high-quality case reports, small case series, novel techniques, and innovations in all aspects of vascular disease, including arterial and venous pathology, trauma, The veins of the stomach run parallel to the arteries.
