Variations of the arterial and venous system of the abdomen and pelvis have important clinical significance in hepatobiliary surgery, abdominal laparoscopy, and radiological intervention. A case of double inferior vena cava (IVC) with complex interiliac communication and variation of the common hepatic artery (CHA) arising from superior mesenteric artery (SMA) in a 79-year-old male cadaver is p...

The use of thermoregulatory catheters (TRCs) in critically ill patients has become increasingly popular. TRCs have been shown to be effective in regulating patient body temperature with improved outcomes. Critically ill patients, especially multitrauma patients and those with femoral catheters, are at high risk for deep vein thrombosis (DVT). Among patients for whom chemical DVT prophylaxis is ...

BACKGROUND Central venous pressure (CVP) and right atrial pressure (RAP) are important parameters in the complete hemodynamic assessment of a patient. Sonographic measurement of the inferior vena cava (IVC) diameter is a non-invasive method of estimating these parameters, but there are limited data summarizing its diagnostic accuracy across multiple studies. We performed a comprehensive review ...

OBJECTIVE To review the evidence for using inferior vena cava (IVC) filters to prevent pulmonary embolism (PE) in high-risk patients. QUALITY OF EVIDENCE Ovid MEDLINE was searched from 1966 to 2006 for all English-language papers on IVC filters. Evidence was graded according to the 3-level classification system. Most evidence found was level II. MAIN MESSAGE Inferior vena cava filters are u...

AIMS This study aimed to investigate the safety and efficacy of preoperative temporary inferior vena cava (IVC) filter placement and intraoperative application of a liver mobilization technique. MATERIALS AND METHODS The experiment cohort of 42 cases and the control cohort of 36 cases of renal cell carcinoma involving the IVC were analyzed retrospectively. In the experiment cohort, patients w...

As the demand for cloned embryos and offspring increases, the need arises for the development of nuclear transfer procedures that are improved in both efficiency and ease of operation. Here, we describe a novel zona-free cloning method that doubles the throughput in cloned bovine embryo production over current procedures and generates viable offspring with the same efficiency. Elements of the p...

In vitro culture (IVC), used in assisted reproductive technologies, is a major environmental stress on the embryo. To evaluate the effect of IVC on mitochondrial transcription and the control of mtDNA replication, we measured the mtDNA copy number and relative amount of mRNA for mitochondrial-related genes in individual rat oocytes, zygotes and embryos using real-time PCR. The average mtDNA cop...

This report evaluates the efficiency and safety of catheter-directed thrombolysis (CDT) using tissue plasminogen activator (tPA) and argatroban for the treatment of IVC filter thrombosis complicated by heparin-induced thrombocytopenia (HIT). From October 2012 to December 2014, 19 patients with unilateral lower extremity deep venous thrombosis were treated with standard anticoagulation, filter p...

Left atrial muscle extends into the proximal third of the mitral valve (MV) anterior leaflet and transient tensing of this muscle has been proposed as a mechanism aiding valve closure. If such tensing occurs, regional stiffness in the proximal anterior mitral leaflet will be greater during isovolumic contraction (IVC) than isovolumic relaxation (IVR) and this regional stiffness difference will ...

2 In recent years, there has been increasing interest in inter-vehicle communications (IVC) 3 based on wireless networks to collect and distribute traffic information in various Intelligent 4 Transportation Systems applications. In this paper, we study the performance of IVC under 5 various traffic and communication conditions by means of simulation analysis. We consider 6 impacts of shock wave...
