[Complete Remission of Metastatic Renal Cell Carcinoma with Invasion of the Duodenum and Pancreas after Treatment with Nivolumab Plus Ipilimumab Followed by Axitinib and Surgery : A Case Report].

A man in his 60s was diagnosed with clear cell carcinoma of the right kidney with multiple lung metastases, tumor thrombus of the inferior vena cava (IVC), and invasion of the duodenum and pancreas. Ipilimumab plus nivolumab was administered as first-line therapy. After 3 treatment courses, computed tomography (CT) demonstrated a slight decrease in the size of the primary tumor and lung metastases.

Real-time surveillance of left atrial appendage thrombus during contrast computed tomography imaging for catheter ablation: THe Reliability of cOMputed tomography Beyond UltraSound in THROMBUS detection (THROMBUS) study.

Left atrial contrast computed tomography (LA-CT) as well as transesophageal echocardiography (TEE) can exclude left atrial appendage (LAA) thrombus, but is sometimes unable to evaluate LAA due to incomplete LAA filling. The aim of the current study was to validate the utility of real-time approach of LA-CT with real-time surveillance of LAA-filling defect (FD). We enrolled consecutive 894 patients with LA-CT studies acquired for catheter ablation and compared the diagnostic accuracy in demonstrating LAA-FD between conventional protocol (N = 474) and novel protocol with real-time surveillance of LAA-FD immediately after the initial scanning and, when necessary, adding delayed scanning in the supine or prone position (N = 420).
