Background & Objectives: To evaluate the advantages of the one and a half ventricle repair on maintaining a low pressure in the inferior vena cava district. Also evaluate the competition of flows at the superior vena cava – right pulmonary artery anastomosis site, in order to understand the hemodynamic interaction of a pulsatile flow in combination to a laminar one. Materials & Methods: Adult rabbits (n=30) in terminal anaesthesia with a follow up of 8 h were used, randomly distributed in three experimental groups: Group 1: animals with an anastomosis between superior vena cava and right pulmonary artery, as a model of one and one half ventricle repair; Group 2: animals with the cavopulmonary anastomosis followed by clamping of the right pulmonary artery proximal to the anastomosis; and Group 3: sham animals. Pressures of superior vena cava and pulmonary arteries were afterwards measured, in a resting condition as well as after induced pharmacological stress test.Results: In Group 1, superior vena cava pressure was significantly higher, while venous pressure in the inferior vena cava – right atrium district was constant or lower in comparison with the other groups. After stress test, the pressure in the superior vena cava and the heart rate both increased further, but the right ventricular, right atrial and pulmonary artery pressures remained similar to the values in a resting condition. This proved that the inferior vena cava return was well-preserved, and no venous hypertension was present in the inferior vena cava district even after stress test (good exercise tolerance).Conclusion: One and one half ventricle repair can be considered a good surgical strategy for maintaining a low pressure in the inferior vena cava district with potential for right ventricle growth, restoring the more physiological circulation in borderline or failing right ventricle conditions. The experiment presented a positive finding in favour of one and one half ventricle repair, as compared to Fontan type procedure.

Aim. To study the capabilities of radioechocardigraphy in the evaluation of pulmonary hypertension of various causes, early non-invasive detection of pressure increase in the pulmonary artery.Methods. The study included 800 patients with congenital (269) and acquired (217) mitral valve diseases, pulmonary embolism (140), primary pulmonary hypertension (57), coronary heart disease with acute myocardial infarction (117) of different age and gender. Digital radiography, linear tomography of chest, ECG, echocardiography, multidetector computed tomography angiography, and ultrasound of inferior vena cava were performed.Results. Radiocardiography combined with linear tomography and measurement of Moore index, right atrium index, transpulmonary distance, and width of right descending pulmonary artery at the level of intermediate bronchus, allows determining the degree, type (arterial, venous, capillary, and mixed) and cause of pulmonary hypertension. Digital radiography and linear tomography in 80% cases reveal signs of pulmonary embolism. Echocardiography makes it possible to study hemodynamics in pulmonary hypertension, to detect the dilation of the right heart, inferior vena cava, and renal veins, and to calculate the systolic pressure in the right ventricle, pulmonary artery, and right atrium. Radioechocardigraphy allows determining the cause and degree of pulmonary hypertension, and hemodynamic disorders. Sensitivity of the method for diagnosis of pulmonary hypertension is 89%, specificity is 90%, and precision is 92%.Conclusion. Radioechocardigraphy is a highly effective method for diagnosis of pulmonary hypertension; ultrasound of inferior vena cava, iliac veins, and veins of the lower limbs allows to determine the source of pulmonary embolism, to diagnose embologenicity of thromboses and to evaluate the need for vena cava filters.

Parasympathetic pathways mediating chronotropic and dromotropic responses to cervical vagal stimulation were determined from sequential, restricted, intrapericardial dissection around major cardiac vessels. Although right cervical vagal input evoked significantly greater bradycardia, supramaximal electrical stimulation of either vagus produced similar ventricular rates, both with and without simultaneous atrial pacing. Dissection of the triangular fat pad at the junction of the inferior vena cava-inferior left atrium (IVC-ILA) invariably eliminated all vagal input to the atrioventricular (AV) nodal region. Yet IVC-ILA dissection had minimal influence on evoked-chronotropic responses to either cervical vagal or stellate ganglia stimulation. Respective intrapericardial projection pathways, from either right or left vagi, are sufficiently distinct to allow unilateral parasympathetic denervation of the sinoatrial (SA) and atrioventricular (AV) nodal regions. Left vagal projections to the SA and AV nodal regions course primarily along and between the right pulmonary artery and left superior pulmonary vein. Right vagal projections to the SA and AV nodal regions are somewhat more diffuse but concentrate around the right pulmonary vein complex and adjacent segments of the right pulmonary artery. We conclude there are parallel, yet functionally distinct, inputs from right and left vagi to the SA and AV nodal regions.

Introduction: Autosomal dominant polycystic kidney disease is a common syndrome. Renal and hepatic cysts can cause discomfort, bleeding, rupture, infection, hypertension and a mass effect with compression of adjacent organs. Case presentation: A 48-year-old man with polycystic kidney disease and hypertension presented to the emergency department for bilateral flank pain. An abdominal computed tomography scan with contrast showed a 7 cm heterogeneous process posteriorly and laterally to the right kidney. It appeared to be a renal cyst associated with bleeding and bilateral pulmonary artery filling defects, apparently due to  pulmonary embolism. Cavography following inferior vena cava filter insertion did not show any deep vein thrombosis. Discussion and conclusion: The pulmonary embolism was probably caused by extrinsic inferior vena cava compression by a liver cyst. Virchow's triad of stasis, vessel damage and hypercoagulability probably resulted in a thrombus which moved on the right side to the pulmonary artery.

Abstract Background Emphysematous pyelonephritis (EPN) with gas in the inferior vena cava (IVC) is a rare presentation and to our knowledge, this is the first case report in the urologic literature. Case presentation A 35-Year-old obese diabetic Hispanic female presented to the emergency room with a clinical picture of septic shock. Prompt computerized tomography scan revealed EPN with gas throughout the right renal parenchyma and extending to the right renal vein, IVC, and pulmonary artery. She died before surgical intervention Conclusion This case demonstrates that patients presenting with severe EPN have a high mortality risk and providers should acknowledge that septic shock, endogenous air emboli, or a combination of both could result in cardiovascular collapse and sudden death.

Budd-Chiari syndrome (BCS) results from the occlusion or flow reduction in the hepatic veins or inferior vena cava and can be treated with transjugular intrahepatic portosystemic shunt when hepatic vein recanalization fails.1-3 Hypercoagulable patients with primary BCS are predisposed to development of new areas of thrombosis within the TIPS shunt or IVC. This case details a patient with BCS, pre-existing TIPS extending to the right atrium, and chronic retrohepatic IVC thrombosis who underwent sharp recanalization of the IVC with stenting into the TIPS stent bridging the patient until his subsequent hepatic transplantation.
