OBJECTIVE: Focused transthoracic echocardiography (FTTE) is an emerging tool in the management of critically ill patients, but the lack of adequate training models has limited the expansion of this technology. Although basic FTTE training courses have been shown to be sufficient in developing echocardiography skills, limited data exist regarding skill retention. In an effort to develop an adequate FTTE training model, we sought to determine the degree of skill retention after FTTE training...

BACKGROUND: Patients with tumors invading major veins may require combined resection and reconstruction. However, venous reconstruction often demands complex hepatobiliary and vascular surgical procedures. In this study, we report a simple patch repair technique for venous reconstruction using the repermeabilized umbilical vein of the round ligament. METHODS: We reviewed the outcomes of eleven patients who underwent venous wedge resection and patch repair using the repermeabilized umbilical vein of the round ligament at our institution...

The most common extraintestinal complication of Entamoeba histolytica is amoebic liver abscess (ALA). Hepatic vein and inferior vena cava (IVC) thrombosis are rare but well-documented complications of ALA, typically attributed to mechanical compression and inflammation associated with a large abscess. We present a case of a previously healthy 43-year-old Canadian man presenting with constitutional symptoms and right upper quadrant abdominal pain. He was found to have thrombophlebitis of the IVC, accessory right hepatic vein, and bilateral iliac veins...

It has been demonstrated that extracellular calcium is necessary in fertilisation and embryo development but the mechanism is still not well understood. The present study mainly focussed on the extracellular calcium effector called the calcium-sensing receptor (CASR) and examined its expression in porcine gametes and embryos and its function during fertilisation and early embryo development. By using reverse transcription polymerase chain reaction, CASR was found to be expressed in porcine oocytes, spermatozoa and embryos at different developmental stages...

OBJECTIVES: To evaluate normative sonographic measurements of the inferior vena cava (IVC), aorta (Ao), and IVC/Ao ratio in the first 2 days of life in term neonates. METHODS: We prospectively observed 200 term (more than 36 and 6/7 weeks of gestation), single, healthy neonates born in a city hospital. The exclusion criteria were congenital abnormalities, an Apgar score of less than 8, and hyperbilirubinemia requiring phototherapy. Maximum IVC (distal to the hepatic-IVC junction) and Ao (above the superior mesenteric artery) diameters were measured in the first 2 days of life in the longitudinal plane...

INTRODUCTION: Retrievable inferior vena cava (IVC) filters have been increasingly used in patients with major trauma who have contraindications to anticoagulant prophylaxis as a primary prophylactic measure against venous thromboembolism (VTE). The benefits, risks and cost-effectiveness of such strategy are uncertain. METHODS AND ANALYSIS: Patients with major trauma, defined by an estimated Injury Severity Score >15, who have contraindications to anticoagulant VTE prophylaxis within 72 hours of hospitalisation to the study centre will be eligible for this randomised multicentre controlled trial...

Anaplastic thyroid cancer is the rarest tumour of the thyroid gland, representing only 2% of clinically recognised thyroid cancers. The most common metastatic sites are lungs, followed by the intrathoracic and neck lymph nodes. We report the case of a 62-year-old woman who presented to our setting with multiple soft tissue nodules, thyroid mass, head swelling and weight loss. Radiological investigation showed a large thyroid mass with widespread metastasis in subcutaneous tissues of both upper limbs, chest and abdomen...

Pheochromocytoma associated with inferior vena cava (IVC) thrombosis is very rare. A 27-year-old female presented with right flank pain and hypertensive urgency. Contrast-enhanced CT abdomen and gadolinium-contrast MRI abdomen revealed right adrenal mass suspicious of malignancy with invasion and compression to the right IVC wall along with IVC thrombus extending from the level of renal veins to the level of confluence with hepatic veins. Her routine laboratory investigations including 24-hour urine fractionated metanephrines, vanillylmandelic acid, and cortisol were normal...

PURPOSE: Intravitreal injection of conbercept (IVC) is the latest applied treatment that could be used in retinopathy of prematurity (ROP) patients. The structural outcomes and recurrence of ROP among patients treated with IVC or intravitreal injection of ranibizumab (IVR) were compared. METHODS: A consecutive case series of ROP treated with IVC or IVR were retrospectively studied. The primary outcome was treatment success defined as regression of plus disease. The secondary outcomes were recurrence of plus, times of injection, and the final regression of disease...

BACKGROUND: The use of resuscitative endovascular balloon occlusion as a maneuver for occlusion of the aorta is well described. This technique has life-saving potential in other cases of traumatic hemorrhage. Retro-hepatic inferior vena cava (IVC) injuries have a high rate of mortality, in part, due to the difficulty in achieving total vascular isolation. This studies purpose was to investigate the ability of resuscitative balloon occlusion of the IVC (REBOVC) to control supra-hepatic IVC hemorrhage in a swine model of trauma...

Use of retrievable inferior vena cava filters (RIVCFs) has grown exponentially since their introduction into clinical practice, but many of these devices are not retrieved. Some are not retrieved due to poor clinical follow-up, but other devices remain in situ for extended periods because they present significant technical challenges during retrieval. Because of these and other factors, many of these devices were thus left in place permanently. However, recent data have placed a renewed emphasis on device retrieval due to increased risk of RIVCF-related complications, which are positively correlated with filter dwell time...

PURPOSE: To compare treatment outcomes of robotic inferior vena cava (IVC) thrombectomy (R-IVCTE) vs open IVC thrombectomy (O-IVCTE) for renal tumors with level I-II IVC tumor thrombus. MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who underwent either R-IVCTE or O-IVCTE between 2006 and 2015. To reduce the inherent biases of a nonrandomized study, robotic and open groups were matched 1:1 based on key variables. Perioperative data and oncologic outcomes were reviewed...

A venous aneurysm (VA) is a relatively rare disease defined by cystic vasodilated lesions in a general vein. Popliteal venous aneurysm (PVA) is a rare clinical entity, and the first signs may be a thromboembolic event. They can cause potentially life-threating diseases, such as pulmonary embolism and deep venous thrombosis. A left-sided inferior vena cava (IVC) is a common anomaly associated with venous thrombus, resulting in anatomical variations in the venous return from the lower limbs. The general vascular malformation of PVA and left-sided IVC should also be preoperatively understood because of the unpredictable risk of thromboembolic complications...

Blood temperature is a key determinant of tissue temperature and can be altered under normal physiological states, such as exercise, in diseases such as stroke or iatrogenically in therapies which modulate tissue temperature, such as therapeutic hypothermia. Currently available methods for the measurement of arterial and venous temperatures are invasive and, for small animal models, are impractical. Here, we present a methodology for the measurement of intravascular and tissue temperature by magnetic resonance imaging (MRI) using the lanthanide agent TmDOTMA(-) (DOTMA, tetramethyl-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid; Tm, thulium)...

The porcine model is often used in clinical trials. The pig has many fundamental anatomic, physiological and nutritional similarities to humans. Additionally, the European Medicines Agency (EMA) demands the use large animals in clinical studies. Oral mucosa has received special attention due to its regenerative properties. Oral tissue is composed of several types of cells including fibroblasts and keratinocytes. The porcine oral mucosa/buccal pouch mucosa has a cellular structure with defined proliferation and differentiated capability...
