AbstractElastography is an established technique in the evaluation of chronic liver diseases. While there is a large clinical experience and data available regarding the performance of elastography in native liver, elastography experience with liver grafts is limited and still growing. Both ultrasound-based elastography techniques and MR Elastography (MRE) are useful in the assessment of liver fibrosis in liver transplants. Technical modifications for performing elastography will be required for optimum evaluation of the graft. In general, caution needs to be exercised regarding the use of elastography immediately followin...

Rationale: Liver transplantation (LT) is the preferred surgical option for the treatment of early hepatocellular carcinoma (HCC). In contrast, surgical treatment of progressive HCC metastasized to the spine following LT constitutes a considerable challenge. Here, we report the first case of progressive HCC metastasized to the T12 vertebra after local radiotherapy, treated successfully with en bloc lumpectomy following LT for HCC. Patient concerns: A 40-year-old man who had undergone LT for the treatment of HCC 2 months prior presented to our clinic with symptoms of progressive back pain. Magnetic resonance imagining (...

Cardiac Allograft Vasculopathy (CAV) is a major cause of chronic cardiac allograft failure. Invasive coronary angiography (ICA) and intravascular ultrasound (IVUS) are the current diagnostic methods. Myocardial perfusion MRI has become a promising non-invasive method to evaluate myocardial ischemia, but has not been thoroughly validated in CAV. Our objective was to assess the repeatability of myocardial rest-perfusion MRI in healthy volunteers and its feasibility in detecting CAV in transplant patients (Tx).

AbstractLiver transplantation has become a definitive treatment for patients with end-stage liver disease and those meeting Milan criteria for hepatocellular carcinoma. The morbidity and mortality associated with liver transplantation continues to decrease thanks to refinements in surgical technique, immunosuppression, and imaging. In particular, imaging plays a vital role by facilitating early detection of post-operative complications and enabling prompt treatment. Post-operative complications that lead to graft failure and patient morbidity/mortality can be generally categorized as vascular, biliary, parenchymal, and mal...

A 63-year-old man was admitted 2 months after a deceased-donor kidney transplantation with an acute rise of his creatinine from a baseline of 1.9 mg/dl to 3.7 mg/dl. The patient had received basiliximab induction, followed by maintenance with belatacept, mycophenolic acid, and steroids. Physical examination and an ultrasound of the kidney transplant were unremarkable. Kidney biopsy revealed Banff acute cellular rejection grade IIB. Belatacept was replaced with tacrolimus, and steroid pulse and rabbit antithymocyte globulin were administered.

AbstractThermal ablative techniques have been increasingly recognized as a valuable alternative to graftectomy and nephron-sparing surgery for the treatment of small neoplasms arising in the transplanted kidney. However, long-term efficacy and safety data are still lacking. In particular, current experience with microwave ablation is limited to a very recent single-centre series of three cases. We herein report two microwave ablations of renal cell carcinoma of the kidney allograft. The procedures were successfully performed under ultrasound guidance with complete tumour necrosis, no peri-operative complications, and prese...

We present the case of a 46-year-old man who underwent successful antegrade ureteroscopy for lithiasis in his allograft ureter. At a scheduled follow-up 15  years after transplantation, computed tomography (CT) detected a 12-mm renal stone in the renal pelvis of the transplanted kidney. During his follow-up, gross hematuria was seen; the stone moved to the ureter, causing hydronephrosis. Ultrasound and non-contrast CT revealed hydronephrosis and a 15- mm stone in the transplanted ureter. Considering the stone size, location, and the difficulty of the access to the anastomosed ureteral orifice, percutaneous ureteroscop...

Conclusions. Our study suggests that cell-MBs can function as a promising probe to image the dynamic lymphocyte–endothelium adhesion cascade for noninvasive diagnosis of cardiac acute cellular rejection.

In patients awaiting heart transplantation (HTx), end-stage disease of a second organ may occasionally require consideration of simultaneous multiorgan transplantation. As cardiac and renal disease are related physiologically and often co-exist, the population of combined heart and kidney transplantation (HKTx) has significantly increased over the last few years along with the growing number of patients wait listed for heart.1,2 Interestingly, short-term survival rates after HKTx have been reported to be comparable to those after isolated HTx.
