A 92-year-old woman visited the hospital with edema of both lower extremities. Computed tomography revealed her inferior vena cava (IVC) was compressed by a massive hepatic cyst. A massive IVC thrombosis and pulmonary thromboembolism (PTE) were also observed. Medical treatment rather than radiologic intervention was preferred because of the patient's advanced age and poor performance status. IV...

A 76-year-old man with autosomal dominant polycystic kidney disease (ADPKD) was admitted complaining of severe edema of bilateral lower extremities. Computed tomography (CT) of his abdomen revealed an enlarged hepatic cyst with intra-cystic hemorrhage, and massive thrombosis in the inferior vena cava (IVC). The extrinsic mechanical stress on the IVC seemed to induce thrombosis within the IVC, a...

The complex embryogenesis of the inferior vena cava (IVC) may result in several anomalies, often presenting as an incidental radiological finding. In addition to the differential diagnosis with pathological lesions, recognizing IVC defects is crucial for invasive procedures. This report describes a patient with a right femoral vein thrombosis who could not be given anticoagulant therapy due to ...

Superior vena cava (SVC) and inferior vena cava (IVC) pressures were measured serially during laparoscopic cholecystectomy in which the intra-abdominal pressure was maintained at 12 mmHg. The influences of alteration of position from 15 degrees head-down to 15 degrees head-up and of the operative procedure of holding the gallbladder up to the right subphrenic space on SVC and IVC pressures were...

BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) often infiltrates to the adjacent major vasculatures; however, direct invasion of PDAC to the inferior vena cava (IVC) is uncommon. CASE PRESENTATION We report our experience with three cases of PDAC directly invading the IVC wall. All three patients underwent pancreatoduodenectomy along with wedge resection of the IVC wall without severe pos...

Duplicated inferior vena cava (IVC) is a rare congenital anomaly. We describe the utility of a new graft from the left IVC in a patient with duplicated IVC for reconstructing the middle hepatic vein (MHV) after partial hepatectomy with MHV resection. A 67-year-old woman with hepatitis C was found to have a liver tumor. Magnetic resonance imaging confirmed that the tumor, which was attached to t...

BACKGROUND We determined the value of the inferior vena cava (IVC) diameter for predicting acute blood loss in control and blunt trauma patients and compared this with other parameters of hemorrhagic shock. METHODS Fifty volunteers and 28 consecutive hemorrhagic shock patients were recruited prospectively to participate in the study. Vital signs, blood lactate, and serum bicarbonate were meas...

INTRODUCTION Deep vein thrombosis (DVT) continues to be a significant source of morbidity for surgical patients. Placement of a retrievable inferior vena cava (IVC) filter is used when patients have contraindications to anticoagulation or recurrent pulmonary embolism despite therapeutic anticoagulation. Although retrievable IVC filters are often used, they carry a unique set of risks. PRESENT...

Recently, intelligent transportation systems (ITS) is becoming an important research topic. One goal of ITS is to exchange information among vehicles in a timely and efficient manner. In the ITS research community, inter-vehicle communications (IVC) is considered a way that may be able to achieve this goal. An information network built on the top of vehicles using IVC can be viewed as a type of...

The aim of the study was to explore the long- and short-axis dimensions, shape and collapsibility of the inferior vena cava in 46 trained and 48 untrained females (mean age: 21 ± 2 y). Echocardiography in the subcostal view revealed a larger expiratory long-axis diameter (mean: 24 ± 3 vs. 20 ± 3 mm, p < 0.001) and short-axis area (mean: 5.5 ± 1.5 vs. 4.7 ± 1.4 cm2, p = 0.014) in trained females...
