Studies were performed on anesthetized saline-loaded dogs to delineate the afferent and efferent mechanisms involved in the antinatriuretic response to acute constriction of the thoracic vena cava. The kidneys of the animals were denervated prior to study, and renal perfusion pressure was controlled throughout the experiment. To differentiate between the potential afferent stimuli, increased he...

The best known treatment of the colorectal liver metastasis is the complete surgical excision with clean surgical margins. However, liver resections sometimes cannot appear technically feasible due to the high number of metastases in the liver, in cases of recurrent resections or invasion of the tumors to the major vascular structures or neighboring organs. Here, we presented a colorectal recur...

Abnormal connection of the right superior caval vein to the left atrium is an uncommon systemic vein drainage anomaly, with only a few cases reported among congenital heart disease (CHD), around 20 cases published in the medical literature. The inferior vena cava connection with the left atrium, also very rare, can appear directly or in heterotaxy. Clinical suspicion arises due to the presence ...

OBJECTIVE To assess flow dynamics after total cavopulmonary connection (TCPC). DESIGN Cross-sectional study. SETTING Aarhus University Hospital. PATIENTS Seven patients (mean age 9 (4-18) years) who had previously undergone a lateral tunnel TCPC mean 2 (0. 3-5) years earlier. INTERVENTIONS Pressure recordings (cardiac catheterisation), flow volume, and temporal changes of flow in the la...

OBJECTIVE To measure caval and pulmonary flows at rest and immediately after exercise in patients with total cavopulmonary connection (TCPC). DESIGN An observational study using the patients as their own controls. SETTING Using a combination of magnetic resonance (MR) phase contrast techniques and an MR compatible bicycle ergometer, blood flow was measured in the superior vena cava, the tun...

BACKGROUND The purpose of this study was to evaluate the results of hepatectomy with inferior vena cava or hepatic vein resection, followed by vessel reconstruction with an artificial vascular graft. METHODS From 2000 to 2011, 1,434 patients underwent several types of hepatectomy at our institution. Of these, we reviewed the cases of eight patients (0.56%) who underwent hepatectomy with infer...

BACKGROUND Although mediastinal tumors compressing or invading the superior vena cava represent the major causes of the superior vena cava syndrome, benign processes may also be involved in the pathogenesis of this medical emergency. One of the rarest benign causes is a pseudoaneurysm developing in patients previously having heart surgery. CASE REPORT We present the case of a large pseudoaneu...

BACKGROUND The development of reconstructive venous surgery has been hampered by the lack of suitable grafts. Patency rates with grafts in the venous system are commonly less satisfactory than in arterial system, mainly due to nonpulsatile flow velocity and the low pressure in veins. Grafting of the inferior vena cava may be necessary in cases of trauma and major tumor surgery involving the vei...

In this study, we report on our first experience with the construction of a valve using autologous vena cava tissue for right ventricular outflow tract reconstruction. Simulating the clinical situation valves were built from tubular pieces of porcine inferior vena cava placed in a PTFE tube and investigated in a pulsatile flow simulator. Based on the given vena cava dimensions, conduits were co...
