BACKGROUND This study was aimed to assess the effects of angiotensin II (Ang II) supplementation to the In Vitro Maturation (IVM) and In Vitro Culture (IVC) media of vitrified-warmed ovine oocytes on their developmental competence and expression of Na(+)/K(+)/ATPase in resulting embryos. METHODS The slaughterhouse-derived immature oocytes (n=1069) were randomly distributed into four experimen...

OBJECTIVE To determine whether the inferior vena cava (IVC) measurement by bedside ultrasound (US-IVC) predicts improvement in renal function in patients with acute kidney injury (AKI). DESIGN Prospective observational study. SETTING Medical intensive care unit. PATIENTS 33 patients with AKI were included. INTERVENTION US-IVC was done on admission. The patients' management was done by t...

A 51-year-old man with a renal carcinoma with inferior vena cava (IVC) invasion was referred to our hospital for the performance of a radical nephrectomy with IVC thrombus excision. To prevent embolism, an IVC filter was implanted the day before surgery below the suprahepatic veins. On nephrectomy completion, the clinical status of the patient started to deteriorate and an unsuccessful attempt ...

Introduction. Leiomyosarcomas of vascular origin are particularly rare tumors occurring mainly in the inferior vena cava (IVC). They are malignant, slow-growing tumors with a poor prognosis. This paper reports on a rare case of surgical resection of an IVC leiomyosarcoma mimicking a hepatic tumor. Case Presentation. A 65-year-old Japanese male was admitted for evaluation of an abdominal tumor. ...

Compared to the abdominal aorta, the hemodynamic environment in the inferior vena cava (IVC) is not well described. Using cine phase-contrast magnetic resonance imaging (MRI) and a custom MRI-compatible cycle in an open-magnet, we quantified mean blood flow rate, wall shear stress, and cross-sectional lumen area in eleven young, normal subjects at the supraceliac and infrarenal levels of the ao...

With the use of cine phase-contrast magnetic resonance imaging (MRI) and a custom MRI-compatible cycle in an open magnet, we quantified mean blood flow rate, wall shear stress, and cross-sectional lumen area in 11 young normal subjects at the supraceliac and infrarenal levels of...

AIM Congenital anomalies of the inferior vena cava (IVC) are very rare and extremely diverse, reflecting the complexity of the embryological development of these structures. The variants must be differentiated from pathology, particularly lymphadenopathy, on imaging studies as their presence can affect surgical and interventional procedures in retroperitoneum. We describe two patients with rena...

Inferior Vena Cava (IVC) filters are mechanical devices implanted to provide prophylaxis against pulmonary emboli in patients for whom standard anticoagulation is either inadequate or contraindicated. A 67-year-old female with a 10-year-old indwelling IVC filter underwent robotic assisted laparoscopic partial nephrectomy for a right upper pole renal mass. Renal hilum dissection was complicated ...

INTRODUCTION Renal vein or inferior vena cava (IVC) invasion by neoplastic thrombus in patients with renal cell carcinoma (RCC) is not an obstacle for radical oncological treatment. The aim of this study is to present our technical maneuvers for complete removal of the intracaval thrombus without compromising hemodymanic stability of the patient. MATERIALS AND METHODS Between 2000 and 2014, 1...

BACKGROUND Prior research suggests that the ratio of the ultrasound-measured diameter of the inferior vena cava to the aorta correlates with the level of dehydration in children. This study was designed to externally validate this and to access the accuracy of the ultrasound measured inspiratory IVC collapse and physician gestalt to predict significant dehydration in children in the emergency d...
