Medullary Tissue Sampling in Renal Allograft Biopsy is More Sensitive for Pathologic Diagnosis of PVN
Background Post-transplant polyoma virus nephropathy (PVN) prevalence is 1-10%. Definitive PVN diagnosis requires polyoma virus presence in infected cells, done with immunohistochemical staining for SV40…2018 American Transplant Congress
Hepatic Artery Resistive Indices on Doppler Ultrasound at Long Term Follow Up in Liver Transplant Recipients: Importance and Implications
Abdominal Transplant Surgery, The University of North Carolina, Chapel Hill, NC.
Ultrasound Doppler has a proven value in early post transplant period, however the importance at the long term follow up is not proven. Doppler results…2018 American Transplant Congress
Deep Vein Thrombosis in Heart Transplant Patients
Heart Institute, Advocate Christ Medical Center, Oak Lawn, IL.
Introduction:Deep Vein Thrombosis (DVT) is one of the leading causes of cardiovascular morbidity and mortality. The incidence of DVT is usually higher in the lower…2018 American Transplant Congress
Prediction of Renal Allograft Chronic Rejection Using a Model Based on Contrast EnhancedUltrasonography
Contrast-enhanced ultrasonography (CEUS) represents microperfusion status of transplanted kidneys. Herein, we evaluate the application of CEUS in the assessment of renal allograft rejection by establishing…2018 American Transplant Congress
Evaluation of Transplant Kidneys Using a Novel Point of Care 3D Ultrasound System
1Duke University, Durham, NC; 2Stanford University, Palo Alto, CA.
Purpose: The clinical utility of two-dimensional (2D) ultrasound (US) in the evaluation of renal transplant patients is limited by user dependence and restricted planar image…2017 American Transplant Congress
Prediction of Renal Allograft Acute Rejection Using a Novel Non-Invasive Model Based on Acoustic Radiation Force Impulse.
Point shear wave elastography (p-SWE) based on acoustic radiation force impulse (ARFI) is a novel technology to quantify tissue stiffness by measuring shear wave speed…2016 American Transplant Congress
Predictors of Ultrasound Failure to Detect Hepatocellular Carcinoma in Cirrhotic Livers.
University of California, San Francisco, San Francisco, CA.
Background: Current guidelines recommend ultrasound (US) for hepatocellular carcinoma (HCC) surveillance in cirrhotic livers. However, certain patient and disease characteristics may pose a technical challenge…2016 American Transplant Congress
Correlation of the Shear Wave Elastography with Renal Function in Kidney Transplant Recipients: A Proof of Concept Study.
Background: Non-invasive biomarker for kidney allograft fibrosis is needed. Shear wave elastography is a relatively new technique to assess tissue stiffness. Graft rejection and chronic…2015 American Transplant Congress
Clinical and Radiological Predictors of Transplant Renal Artery Stenosis (TRAS)
Elevated peak systolic velocity (PSV) on Doppler ultrasound at the transplant renal artery (TRA) does not always correlate with true transplant renal artery stenosis (TRAS)…2015 American Transplant Congress
The Natural History of Kidney Graft Cortical Microcirculation Determined by Real-Time Contrast-Enhanced Sonography (RT-CES)
Decreasing kidney graft cortical microcirculation has been related to poor prognosis in kidney transplantation. Cortical capillary blood flow (CCBF) can be measured by real-time contrast-enhanced…
