2024年6月12日 · Inferior vena caval thrombosis is an essential diagnosis while evaluating any neoplastic lesion, or portal hypertension. It is also important to differentiate bland thrombus from tumor thrombus. A patient can present with many features which include. Inferior vena cava thrombus can be classified under two broad headings:

2023年8月20日 · Case studies have reported IVC thrombosis identification using ultrasound in the emergency department. Sonographic signs that indicate a potential thrombus include a monophasic waveform by doppler, a choppy sign indicating increased blood velocity, and an inability to compress the vessel.

2015年3月12日 · MR imaging, specifically with breath-hold contrast material–enhanced three-dimensional T1-weighted imaging and balanced steady-state free-precession techniques, is more reliable than CT for evaluation of IVC tumor thrombus (1).

The infrarenal IVC is the typical location for filter placement, but there are instances when suprarenal placement should be considered, including IVC thrombus, extrinsic IVC compression, circumaortic renal vein (Figs. 9b and 10a), pregnancy or other pelvic masses, renal or gonadal vein thrombosis, chronic occlusion or intrinsic narrowing of ...

Power doppler demonstrates incomplete obstruction of the IVC. Further evaluation with contrast-enhanced ultrasound demonstrates vessels within the mass at 46 seconds and enhancement of the mass at 1 minute and 12 seconds. Longitudinal contrast-enhanced CT image (corticomedullary phase) shows thrombus inside the IVC.

2019年9月18日 · The initial ultrasonography examination of the inferior vena cava (IVC) showed a free-floating thrombus distal to the confluence of hepatic veins (Fig 1, Video 1). A subsequent ultrasonography examination showed the migration of the thrombus into the …

Recently, ultrasound has shown promise for quick identification of IVC thrombus. 6 The rapid ultrasound for shock and hypotension (RUSH) protocol, which incorporates assessment of IVC intravascular volume status, can be used for these undifferentiated patients to diagnose conditions not apparent with the standard physical exam. 7, 8 The RUSH exa...

Inferior vena cava thrombosis is a potentially life-threatening condition in which a clot or thrombus forms in the major vessel that returns blood to the heart and lungs. The primary con-cern is that of potentially life-threatening pul-monary emboli, or clots traveling to the lung.

Ultrasonographic measurement of inferior vena cava (IVC) diameter and degree of respirophasic collapse was initially utilized by nephrologists and subsequently cardiologists. It has more recently been integrated into several critical care/emergency ultrasound protocols as a non-invasive estimate of central venous pressure (CVP).

Thrombosis of the inferior vena cava (IVC) is an under-recognized entity that is associated with significant short- and long-term morbidity and mortality. In absence of a congenital anomaly, the most common cause of IVC thrombosis is the presence of an unretrieved IVC filter.
