Abnormalities of the inferior vena cava (IVC) and renal veins are extremely rare. However, with the increasing use of computed tomography (CT), these anomalies are more frequently diagnosed. The majority of venous anomalies are asymptomatic and they include left sided IVC, duplicated IVC, absent IVC as well as retro-aortic and circumaortic renal veins. The embryological development of the IVC i...

BACKGROUND Patients with gynecologic cancer have a high risk of venous thromboembolism (VTE) like patients with other cancers. However, there is little information on risk factors for VTE during gynecologic surgery and no uniform preventive strategy. Our objectives were to identify risk factors for perioperative VTE in gynecologic patients and establish methods for prevention. METHODS We anal...

In postural tachycardia syndrome (POTS), a subtype of orthostatic intolerance, the changes in hemodynamics due to are poorly understood. We speculated that inappropriate venous return, which may occur upright position patients with school-aged POTS, could be detected by echocardiography. Our prospective study was conducted 100 POTS (45 boys and 55 girls), aged 13.1 ± 1.5 years 52 age- sex-match...

This study aimed to analyze the luminal changes in iliocaval veins and their effects on development of signs symptoms chronic venous disease manifesting from inferior vena cava (IVC) filter placement. In this retrospective observational study, patients with an IVC placed subsequent were included. All had a computerized tomography (CT) scan, or without ultrasound, those who underwent interventio...

A correct estimation of volume status and so-called dry weight in dialysis patients remains a difficult clinical problem. Clinical status and chest X-ray are not sensitive enough, while invasively measured central venous pressures are not routinely available. Recently, the sonographic determination of the diameter and collapse of the inferior vena cava (IVC) has been proposed as a noninvasive m...

Intravascular catheters (IVCs) are the most frequently used medical devices in hospitals. However, they are associated with life-threatening IVC-related bloodstream infection (IVC-BSI), which is one of the main hospital-acquired infections, and continue to be associated with morbidity, mortality and additional medical cost. Most published studies focus on measuring the rate of IVC-BSIs and addr...

OBJECTIVES Bedside ultrasonography (US) measurement of the inferior vena cava (IVC) and aorta (Ao) may be useful in objectively assessing children with dehydration. The objectives of this study were 1) to compare the IVC and Ao diameters (IVC/Ao) ratio of dehydrated children with controls and 2) to compare the IVC/Ao ratio before and after intravenous (i.v.) rehydration in children with dehydra...

Abstract Goals of volume management are to accurately assess intravascular and extravascular predict response administration, vasopressor support, or removal. Data reviewed that support the following: 1) Dynamic parameters reliably guide administration may improve clinical outcomes compared static parameters, but some invasive only validated with mechanical ventilation without spontaneous breat...

Thrombus within an inferior vena cava (IVC) filter reduces filter patency and venous return from the lower extremities, and may progress to complete IVC occlusion. The clinical experiences and outcomes of transcatheter thrombolytic therapy for symptomatic IVC thrombosis following filter implantation have not been widely reported. The aim of the current study was to evaluate the efficiency and s...

BACKGROUND The need for patient transport for inferior vena cava (IVC) filter placement impacts patient safety, comfort, charges, and nursing care. Bedside, ultrasound-guided IVC filter placement may offer an acceptable, cost-effective alternative. METHODS Prospective cohort study of 55 consecutive trauma patients requiring IVC filter placement. During a 13-month period (August of 1995-Septem...
