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:
Inferior Vena Caval Thrombosis - StatPearls - NCBI Bookshelf
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.
Considerations for Imaging the Inferior Vena Cava (IVC) …
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 ...
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.
Detection of Inferior Vena Cava Thrombosis Extending into the …
2019年1月23日 · 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...
Detection of an inferior vena cava thrombus in transit by ultrasound
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 …
Management of the Thrombosed Filter-Bearing Inferior Vena Cava
Once patients with filter-bearing IVC thrombosis develop clinical symptoms (typically lower extremity swelling and pain), imaging with ultrasound (US) is generally the first diagnostic examination.
The Role of Intravascular Ultrasound in Venous Thromboembolism
IVUS of the major axial veins provides a 360-degree two-dimensional gray scale ultrasound image of lumen and vessel wall structures. IVUS remains the criterion standard for venous imaging when contemplating catheter-based procedures from the common femoral vein to …
