Clinical evaluation of in silico planning and real-time simulation of hepatic radiofrequency ablation (ClinicIMPPACT Trial).

Objectives: To evaluate the accuracy and clinical integrability of a comprehensive simulation tool to plan and predict radiofrequency ablation (RFA) zones in liver tumors.

Methods: Forty-five patients with 51 malignant hepatic lesions of different origins were included in a prospective multicenter trial. Prior to CT-guided RFA, all patients underwent multiphase CT which included acquisitions for the assessment of liver perfusion.

GPU-based RFA simulation for minimally invasive cancer treatment of liver tumours.

Purpose: Radiofrequency ablation (RFA) is one of the most popular and well-standardized minimally invasive cancer treatments (MICT) for liver tumours, employed where surgical resection has been contraindicated. Less-experienced interventional radiologists (IRs) require an appropriate planning tool for the treatment to help avoid incomplete treatment and so reduce the tumour recurrence risk. Although a few tools are available to predict the ablation lesion geometry, the process is computationally expensive.

Partial splenic embolization in children with hereditary spherocytosis.

Objectives: Although total splenectomy is able to reduce clinical symptoms in patients with hereditary spherocytosis (HS), splenectomized patients are at risk to develop overwhelming bacterial infections and, to a lesser extent, thromboembolic complications. In contrast, partial splenectomy or partial splenic embolization (PSE) may also decrease the rate of hemolytic complications while maintaining residual splenic function. The aim of this study was to investigate the benefit of PSE in children with moderate to severe HS.

Percutaneous nephrostomy and antegrade ureteral stenting: technique-indications-complications.

In this review the technique, indication for and complications of percutaneous nephrostomy (PCN) and antegrade ureter stent insertion are described. In the majority of the cases PCN is performed to relieve urinary obstruction, which can be of benign or malignant nature. Another indication for PCN is for treatment of urinary fistulas.
