A comparative study assessing the efficacy and safety of radiofrequency ablation versus surgical treatment for osteoid osteoma: retrospective analysis in a single institution.

Objective: We aim to evaluate the efficacy of CT-guided percutaneous radiofrequency ablation (RFA) and surgical treatment in osteoid osteoma (OO) treated at the Medical University of Graz.

Materials And Methods: In a single-institution study, we analysed data from January 2005 to January 2021 of patients with histological/radiological diagnosis of OO. CT and MRI scans were reviewed for typical findings.

Non-colorectal liver metastases: A review of interventional and surgical treatment modalities.

Liver metastases (LM) occur in up to 90% either simultaneously with the diagnosis of the primary tumor or at a later time-point. While resection of colorectal LM and resection or transplantation of neuroendocrine LM is part of a standard therapy with a 5-year patient survival of up to 80%, resection of non-colorectal and non-neuroendocrine LM is still discussed controversially. The reason for it is the significantly lower survival benefit of all different tumor entities depending on the biological aggressiveness of the tumor.

The Use of a Commercially Available Endovascular Filter Catheter (Capturex) for Thoracic Endovascular Aortic Repair (TEVAR) in a Patient with a Coral Reef Aorta.

Due to the risk of mobilizing plaque fragments, transfemoral TEVAR is a potentially dangerous procedure in patients with a coral reef aorta. We describe a practical method for transfemoral TEVAR in a patient with a degenerative thoracic aneurysm and a coral reef aorta. After placing a filter catheter in the abdominal aorta via a contralateral percutaneous femoral access, a working channel through the distal thoracic aorta was created with a balloon-expandable stent graft in the coral reef segment.

Influence of safety glasses, body height and magnification on the occupational eye lens dose during pelvic vascular interventions: a phantom study.

Objective: By simulating a fluoroscopic-guided vascular intervention, two differently designed radiation safety glasses were compared. The impacts of changing viewing directions and body heights on the eye lens dose were evaluated. Additionally, the effect of variable magnification levels on the arising scattered radiation was determined.

RFA Guardian: Comprehensive Simulation of Radiofrequency Ablation Treatment of Liver Tumors.

The RFA Guardian is a comprehensive application for high-performance patient-specific simulation of radiofrequency ablation of liver tumors. We address a wide range of usage scenarios. These include pre-interventional planning, sampling of the parameter space for uncertainty estimation, treatment evaluation and, in the worst case, failure analysis.

Computed Tomography Perfusion Following Transarterial Chemoembolization of Hepatocellular Carcinoma: A Feasibility Study in the Early Period.

Objectives: The aim of this study was to assess the feasibility of computed tomography (CT) perfusion in early follow-up after transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC).

Methods: Fifteen patients with a total of 16 HCC who were referred to our institution for TACE were included in the study. Computed tomography perfusion was performed within 1 to 3 days before and 4 to 7 days after TACE.

Immunohistochemical and radiological characterization of wound healing in porcine liver after radiofrequency ablation.

Background: Radiofrequency ablation (RFA) is a minimal invasive therapeutic option for patients with hepatocellular carcinoma or liver metastases. We investigated RFA-induced cellular changes in the liver of pigs.

Material And Methods: Healthy pigs (n=18) were sacrificed between day 0 and 3 months after RFA.

Is Embolization an Effective Treatment for Recurrent Hemorrhage After Hip or Knee Arthroplasty?

Background: Spontaneous recurrent hemorrhage after arthroplasty of the hip or knee is a rare condition. In patients who do not have coagulopathy, the likeliest etiology for hemarthrosis is hypertrophic vascular synovium. Treatments include arthroscopic or open synovectomy, or angiography with embolization; however, because the condition is rare, seldom reported, and debilitating, small case series characterizing the efficacy of any approach are important to allow a collective experience with this condition to emerge.

Effect of hyperthermia on liver cell lines: important findings for thermal therapy in hepatocellular carcinoma.

Background: Hepatocellular carcinoma is the fifth most common malignant tumour, with a high mortality rate. This study aimed to investigate the effect of hyperthermia on HepG2 and LX-1 cell lines to gain more information on thermal treatment of liver tumours.

Materials And Methods: The cell lines HepG2, LX-1 and their co-cultures were heated from 55°C to 85°C for different time spans.

Ibandronate prevents bone loss and reduces vertebral fracture risk in male cardiac transplant patients: a randomized double-blind, placebo-controlled trial.

Bone loss and fractures are common complications after cardiac transplantation (CTP). The aim of this study was to investigate whether intravenous ibandronate is an effective preventive option. Thirty-five male cardiac transplant recipients received either ibandronate (IBN) 2 mg intravenously every 3 mo or matching placebo (CTR) in addition to 500 mg calcium carbonate and 400 IE vitamin D(3).
