OBJECTIVE: To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) combined with percutaneous microwave ablation (MWA) in the treatment of advanced hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Three thousand cases of advanced HCC patients were randomly divided into two groups: 1500 cases in the treatment group were treated with TACE combined with MWA and 1500 cases in the control group were treated with TACE. RESULTS: The effective rate of the treatment group and control group was 71...

CONTEXT: Minimally invasive interventional therapy is now the more effective treatment strategy for organ-confined malignancy in patients who are poor candidates for surgery. Microwave ablation (MWA) in lung malignancy has been receiving much attention as an effective minimally invasive approach. AIMS: The aim of this study is to evaluate the safety and feasibility within 24 h of discharge of patients treated with percutaneous MWA for inoperable malignant lung nodules, and elucidate the factors predisposing to hospital readmission...

AIMS: The aim of this study was to investigate the effect of heat sink on the recurrence of hepatic malignant tumors <3 cm after percutaneous radiofrequency ablation (RFA). SUBJECTS AND METHODS: This study included 564 hepatic malignant tumors <3 cm in 381 patients. Preoperative images were used to determine whether these tumors were adjacent to vessels, and the diameter of adjacent vessels was measured. RFA was performed computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound (US) guidance, and postoperative imaging follow-up was then conducted...

AIM OF STUDY: For the tumor lesions close to capsule of the liver, traditional percutaneous radiofrequency ablation (PRFA) is limited due to high incidence of postoperative complications. The aim of the present study is to whether laparoscopic combined with PRFA (LCPR) could effectively ablate the tumor lesions close to capsule of the liver. METHODS: A total of 119 patients with subcapsular hepatocellular carcinoma (HCC) were divided into two groups: PRFA group (89 patients) and LCPR group (30 patients)...

BACKGROUND: This study was conducted to evaluate the safety and efficacy of ultrasound (US)-guided percutaneous radiofrequency ablation (RFA) for multiple breast fibroadenoma as an alternative to surgical resection. PATIENTS AND METHODS: Sixty-five patients with multiple breast fibroadenoma accepted general anesthesia and US-guided percutaneous RFA in our hospital from September 2014 to January 2016. Contrast-enhanced US (CEUS) was used immediately after operation to determine whether the tumor was ablated completely...

Radiofrequency ablation (RFA) is a minimally invasive procedure used to treat tumors by means of hyperthermia, mostly through percutaneous approach. The tissue temperature plays a pivotal role in the achievement of the target volume heating, while sparing the surrounding healthy tissue from thermal damage. Several techniques for thermometry during RFA are investigated, most of them based on the use of single-point measurement system (e.g., thermocouples). The measurement of temperature map is crucial for the real-time control and fine adjustment of the treatment settings, to optimize the shape and size of the ablated volume...

Liver thermal ablation is an alternative treatment for hepatocellular carcinoma (HCC) and secondary liver malignancies. Microwave ablation (MWA) produces large ablation zones (AZ) in short time; however, AZ prediction is based on preclinical ex vivo models, rising concerns about reproducibility and safety in humans. We aimed to investigate the effects produced by a new-generation MWA system on human liver in vivo with different approaches (percutaneous or intraoperative) and liver conditions (cirrhosis or previous chemotherapy treatment), in comparison with manufacturer-provided predictions based on ex vivo animal models...

A 63-year-old man with a history of remote inferior myocardial infarction and coronary artery bypass grafting (CABG) underwent catheter ablation of ventricular tachycardia (VT). Epicardial catheter ablation of the VT was successful at the crux of the heart despite limited mapping within the pericardial space due to pericardial adhesion. Percutaneous subxiphoidal pericardial approach is usually impossible in patients with a history of open heart surgery due to pericardial adhesions. This report suggested that epicardial VT arising from the crux of the heart could be successfully treated by catheter ablation via subxiphoidal pericardial approach despite pericardial adhesions complicated by prior CABG...

BACKGROUND: Radiofrequency ablation (RFA) is a minimally invasive technique of tumor destruction for patients with hepatic cancer who are not candidates for conventional therapy. The therapy required general anesthesia (GA) or sedation to ensure patient safety and comfort. The study is aimed to report and evaluate factors that influenced the periprocedural anesthetic management, drugs used, and complications during and immediately after RFA procedure for hepatocellular carcinoma. METHODS: For this retrospective study, we included 46 patients who underwent percutaneous RFA under GA or conscious sedation from January 2010 to June 2013 in Aga Khan University Hospital, Pakistan...

Today, in addition to surgery, other local therapies are available for patients with small-size non-small-cell lung cancer (NSCLC) and oligometastatic disease from various cancers. Local therapies include stereotactic ablation radiotherapy (SABR) and thermal ablative therapies through percutaneously inserted applicators. Although radiofrequency ablation (RFA) has been explored in series with several hundreds of patients with pulmonary tumours, investigation of the potential of other ablation technologies including microwave ablation, cryoablation, and irreversible electroporation is ongoing...

BACKGROUND: Development of hypocalcemia after treatment of hyperparathyroidism results in increased costs and risk of poorer outcomes. Previous studies have shown conflicting data about predictors of hypocalcemia after these procedures. HYPOTHESIS/OBJECTIVES: The objective of this study was to investigate whether ionized calcium (iCa) concentrations before treatment are predictive of hypocalcemia or its clinical signs after surgical removal or heat ablation in dogs with primary hyperparathyroidism...

BACKGROUND: Bile duct injury after ablation of malignant liver tumors (MLTs) was not unusual and should be avoided. However, few studies have focused on evaluating the risk factors for intrahepatic bile duct injury. AIM: To evaluate the risk factors for intrahepatic bile duct injury after ablation of MLTs and to evaluate the minimum safe distance for ablating tumors abutting bile ducts. METHODS: Sixty-five patients with intrahepatic bile duct injury after ablation of MLTs, and 65 controls were recruited...

BACKGROUND: In patients with implantable cardioverter-defibrillators, healthcare utilization (HCU) and expenditures related to shocks have not been quantified. METHODS AND RESULTS: We performed a retrospective cohort study of patients with implantable cardioverter-defibrillators identified from commercial and Medicare supplemental claims databases linked to adjudicated shock events from remote monitoring data. A shock event was defined as ≥1 spontaneous shocks delivered by an implanted device...

PURPOSE: To evaluate safety and efficacy of percutaneous hepatic microwave (MW) ablation performed near the heart. MATERIALS AND METHODS: This study reviewed 118 consecutive peripheral (ablation zone margins within 5 mm of liver capsule) percutaneous MW hepatic ablations performed between June 2010 and August 2015. Ablation zones of 27 tumors (22.8%) extended to ≤ 5 mm from myocardium, and these ablations comprised the study group; the remaining ablations formed the control group...

BACKGROUND: In patients with primary colorectal cancer (CRC) or unresectable metastatic CRC, midgut embryonic origin is associated with worse prognosis. The impact of embryonic origin on survival after ablation of colorectal liver metastases (CLM) is unclear. METHODS: We identified 74 patients with CLM who underwent percutaneous ablation during 2004-2015. Survival and recurrence after ablation of CLM from midgut origin (n = 18) and hindgut origin (n = 56) were analyzed...
