Intelligent Soft Opto‐Magnetic Robot for Minimally Invasive Interventional Therapy

Advanced Science, EarlyView.
An intelligent soft opto‐magnetic (iSOM) robot is developed that integrates remote magnetic actuation, skin‐mimic tactile perception, and photothermal ablation in a near‐millimeter‐scale design. It enables precise intraluminal navigation and localized ablation while providing real‐time optical feedback to support safe and accurate minimally invasive ...

Dendritic Nano‐Based Slippery Coating by Synergistic Mechanical and Electrostatic Interactions with Persistent and Exceptional Combats Thrombosis

Advanced Science, EarlyView.
A novel dendritic nano‐based slippery coating (DNSC), fabricated by encapsulating carboxyl silicone oil within amino dendritic silica nanoparticles and co‐embedding them in an epoxy resin matrix. The dendritic architecture enhances nanoparticle dispersion in the matrix and establishes mechanical interlock.

A case of right renal cell carcinoma with an inferior vena cava tumor thrombus extending above the diaphragm resected without cardiopulmonary bypass

Urology Case Reports
We preoperatively evaluated the tumor thrombus of right renal cell carcinoma cT3cN0M0 extending close to the right atrium using abdominal ultrasound. We found that invasion of the inferior vena cava (IVC) by the tumor thrombus was limited to the caudal ...

Massive tumor thrombus in left renal vein and inferior vena cava in renal cell carcinoma on 18-fluorodeoxyglucose positron emission tomography/computerized tomography: “suspension bridge sign”

World Journal of Nuclear Medicine, 2018
Tumor thrombosis is a relatively uncommon complication of renal cell carcinoma (RCC), and its diagnosis has therapeutic and prognostic implication. Computerized tomography (CT) is the primary imaging modality for staging RCC, but it has low sensitivity ...

Prognosis of Hepatocellular Carcinoma with Portal Vein Tumor Thrombus:Assessment Based on Clinical and Computer Tomography Characteristics [PDF]

, 2012
Patients with hepatocellular carcinoma (HCC) complicated by portal vein tumor thrombus (PVTT) have an extremely poor prognosis. It is important to select adequate therapeutic options based on reliable prognostic factors using imaging studies and clinical

MACROSCOPIC TUMOR THROMBUS IN RENAL CELL CARCINOMA

The Japanese Journal of Urology, 1991
Prognosis of 114 patients treated for renal cell carcinoma from 1972 to 1988 was investigated to evaluate intravenous tumor extension as a prognostic factor. Those in whom presence or absence of macroscopic tumor thrombus was not confirmed were not included in the current patient group.
