Long Term Result

Abstract Direct hepatic veins-to-hemiazygos connection offers the balanced distribution of hepatic venous blood to both lungs, not requiring anticoagulation. We report a 13-year follow-up after this type of off-pump Fontan completion. Patient’s hepatic veins-to-hemiazygos confluence increased with growth to allow for unobstructed flow. This unique technique can be recommended in heterotaxy patients, if atrial hepatic venous drainage and hemiazygos vein are in close proximity.

Hepatic Venous Blood

In cats anesthetized with pentobarbital, hepatic venous pressure was increased to cause drops of exudate to appear on the surface of the liver. These drops were collected during steady-state infusions of small doses of ethanol and galactose when there was a large arteriovenous gradient across the liver. Comparison of the concentrations of these substances in arterial, portal, and hepatic venous blood and exudate showed that the exudate concentrations were slightly higher than the hepatic venous concentrations but markedly lower than arterial and portal blood concentrations. We conclude that the exudate cannot be entirely formed in the space of Mall (presinusoidal) but a substantial part is postsinusoidal in origin. If the exudate is a mixture of fluids equilibrated with inflowing and outflowing blood, then 75–80% of the exudate is postsinusoidal and 20–25% is presinusoidal in origin.Key words: lymph, ascites, galactose, ethanol.

Anaphylactic or peptone shock causes a release of heparin which is present in greater concentrations in lymph obtained from the thoracic duct than in either arterial or hepatic venous blood. Frequently heparin is present only in thoracic duct lymph following such shock. The evidence indicates that the source of this heparin is the liver and that during shock its passage from liver to blood is mainly by means of the thoracic duct. Heparin is not released into thoracic duct lymph or blood during a histamine or hemorrhage induced shock.

AbstractWe report on a 12-year-old girl with Ebstein’s anomaly after a unidirectional Glenn procedure with surgical ligation of the proximal right pulmonary artery, who suffered from significant central cyanosis caused by multiple arterio-venous fistulas in the right lung. The continuity between the right pulmonary artery and the pulmonary trunk was restored with the use of radiofrequency perforation and consecutive covered stent implantation.

A method for obtaining pure, mixed hepatic venous blood is described and evaluated in anesthetized cats. Hepatic vascular congestion does not occur with this “intracaval cannulation”, however small elevations in central venous blood pressure were noted. Although these changes persisted they did not result in systemic vascular congestion, judging from the normal arterial and portal pressures and from the lack of progressive decrease in arterial blood pressure. Blood samples obtained using the intracaval cannulation were shown to contain identical levels of oxygen as those obtained using a more complex surgical preparation. Reflux of blood from the vena cava does not occur during sampling. The responsiveness of this sampling method to rapid changes in venous content was evaluated by following the changes in glucose balance caused by direct stimulation of the hepatic nerves. The responses measured were similar to those measured in a separate set of experiments obtained using blood samples from a surgically isolated hepatic venous supply.

Pulmonary Arteriovenous Fistulas

AbstractAbstract Hepatic venous blood has been thought to play some role as a vasoactive agent in the development of pulmonary arteriovenous fistulas in patients with congenital heart disease. During the last 15 years, we have observed pulmonary arteriovenous fistulas in 3, and systemic arteriovenous fistulas in 2, patients from our 16 cases of left isomerism. During the same period, neither pulmonary nor systemic arteriovenous fistulas were detected among 50 patients with right isomerism. Pulmonary arteriovenous fistulas had developed in the absence of surgery in 1 of the patients. Both pulmonary and systemic fistulas were detected in an another patient, in whom the hepatic venous blood bypassed the pulmonary circulation. The level of somatostatin, which is known to reduce splanchnic blood flow, was high in the systemic venous blood of this patient. Although the mechanism of development of the fistulas has yet to be clarified, we should be aware that not only pulmonary, but also systemic arteriovenous fistulas can be found in patients with left isomerism, even prior to any surgical intervention.

Worldwide neonatal sepsis is among the most frequent causes of neonatal death. Various studies have tried to establish the relationship between prevalence of neonatal septicemia risk factors and bacteriological profiling, low birth weight, prematurity, etc. Current study was aimed to compare early onset of neonatal sepsis (EONS) among primigravida and multigravida mothers using umbilical cord blood (UCB) and peripheral venous blood (PVB) samples. It was also aimed to establish the utilization of umbilical cord blood culture (UCBC) in comparison to peripheral venous blood culture (PVBC) in identifying EONS. In present study the blood samples were collected from high risk neonates for the clinical blood culture and screening. Among the 75 neonates in the study, 24 (32.0%) were observed to have sepsis screen positive. Study of high risk neonates umbilical cord blood culture (UCBC) positivity was 17.3% while Peripheral Venous blood culture positivity was 5.3%. Moreover,  in this study all risk factors like Prematurity, Low birth weights, Premature rupture of membrane, and birth asphyxia were significantly (p<0.05) associated with UCBC growth/positivity. Low birth weight (86%) was mostly reported in the high risk neonates with other associated sepsis factors. Similarly maternal fever and prolonged rupture of membrane was highly significantly (p<0.01) associated with UCBC positivity. Gram negative bacterias  were  more  commonly found,  such as Pseudomonas (5.3%), followed by E. coli (4%), and Klebsiella (2.7%) and gram positive Streptococcus sp. (2.7%), etc. From our analysis it can be said that the UCBC has strong diagnostic outcomes as compared to the PVBC for etiological evaluation of bacterial sepsis in neonates at high risk.
