| | Diabetes: Portal Vein Afferents Are Critical for the Symp... @ HighBeam Research |
 | | During portal vein glucose infusion, we previously observed a 67 and 50% attenuation in the epinephrine and norepinephrine responses, respectively. | | | That is, in portally denervated animals, normalization of portal vein glucose during systemic hypoglycemia yielded no suppression in the catecholamine response to systemic hypoglycemia, unlike that observed for SHAM (P = 0.90). | | | Quantitatively, the similar suppression of the sympathoadrenal response by either denervation or normalization of portal vein glycemia suggests that the two experimental approaches elucidate the same population of glucosensors. |

| | Inherited and acquired disorders of the coagulation pathway are frequent causes of portal vein thrombosis. | | | In the setting of acute portal vein thrombosis with symptoms, shunt surgery with subsequent anticoagulation therapy is an alternative. | | | Of all cases of portal hypertension in developing countries, 40% are attributed to portal vein obstruction, presumably secondary to an increased incidence of pylephlebitis associated with abdominal infections. |

| | Portal hypertension results in the development of collaterals to bypass the increased resistance to flow within the portal bed and to return blood to the systemic circulation. | | | Predictive value of the variceal pressure response to continued pharmacological therapy in patients with cirrhosis and portal hypertension. | | | Hence, the primary objective of drug, radiologic, and surgical therapy for portal hypertension is the reduction of HVPG, the target value being 12 mmHg.1 TIPS and surgical shunts achieve this target by creating a low-resistance channel between the hypertensive portal system and the inferior vena cava system. |

| | Sometimes, instead of surgery, a radiologist can connect the hepatic venous system to the portal vein by passing a needle through the skin and directly into the liver; guide wires and catheters are then inserted through the needle and used to create a shunt. | | | A doctor can feel an enlarged spleen, which may be tender. | | | Portal vein thrombosis can be caused by any blood clotting disorder or by any condition that backs up blood in the portal vein, such as Budd-Chiari syndrome, chronic heart failure (see Heart Failure), or chronic constrictive pericarditis (see Pericardial Disease: Chronic Pericarditis). |
