Unexplained liver hemorrhage after metastasis radiofrequency ablation
November 18, 2009Colorectal carcinoma is one of the most common cancers in the world. Approximately one in four of these patients have metastases at diagnosis, liver being the most common site involved. Although historically it was considered that liver metastases meant a very poor prognosis, today, due to improved systemic therapy, many patients will be candidates for local hepatic treatments such as surgery or less aggressive radiofrequency ablation. Both of these procedures have resulted in improvements in global and disease-free survival. However ,a report of unexplained liver haemorrhage after metastasis radiofrequency ablation has been published on October 28, 2009 in the World Journal of Gastroenterology.
Radiofrequency ablation is increasing used in the field of oncology. Although some studies have found low rates of complications, ranging from 2.4% to 8.9%, the rate of intraperitoneal haemorrhage is low (0.46%-1.6%) but relevant because this technique is increasingly used with few selection criteria for patients. The reported reasons for haemorrhage are usually related to mechanical injuries to the liver blood vessels and occur most often in patients with cirrhosis. Other cases have been attributed to serious coughing or hiccups after the radiofrequency treatment which might cause increased abdominal pressure and tumour rupture.
Liver laceration has rarely been described as a cause of haemorrhage. This complication has been associated with inappropriate electrode positioning or mechanical injury of the soft liver during the procedure and possibly displacing the electrode slightly. Although the procedure may go well, the patient could present with this type of complication without known risk factors. This makes it absolutely essential to minimise complications associated with radiofrequency ablation treatments, and to correctly deal with complications which do arise. In all these cases it is relevant to closely observe patients after this procedure to provide early intervention to minimise the damage and severity of complications.

Radiofrequency Ablation Current Events and Radiofrequency Ablation News RSSRadiofrequency ablation safe and effective for reducing pain from bone metastases
Image-guided radiofrequency ablation (RFA), a minimally invasive cancer treatment which can be performed in the outpatient setting, significantly reduced the level of pain experienced by cancer patients with bone (osseous) metastases, limiting the need for strong narcotic pain management, and supporting improved patient frame of mind.
Minimally invasive procedure effective for treating snoring
Radiofrequency ablation, a procedure that uses heat to shrink the tissue of the soft palate, is an effective and minimally invasive procedure that can be used to treat patients who snore.
Researchers effectively treat tumors with use of nanotubes
By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice.
NEJM study finds radiofrequency ablation can reverse Barrett's esophagus, reduce cancer risk
Patients who have gastroesophageal reflux disease (GERD) for a prolonged period have an increased risk of developing Barrett's esophagus, a pre-cancerous condition where the tissue lining the esophagus becomes damaged by stomach acid and transformed into something like the inside of the stomach.
Technique eradicates problems in most patients with Barrett's esophagus
A procedure that uses heat generated by radio waves to treat Barrett's esophagus, a condition caused by acid reflux (severe heartburn), can eliminate signs of the potentially cancer-causing disorder and reduce the risk that the disease will progress.
Landmark UNC-led study finds radiofrequency ablation is effective treatment for Barrett's esophagus
A landmark clinical trial led by a University of North Carolina at Chapel Hill researcher concludes that radiofrequency ablation is an effective treatment for dysplasia in people with Barrett's esophagus, a condition that can lead to deadly gastrointestinal cancer.
Metastatic bone disease patients can walk in Lazarus' footsteps
Osteoplasty-a highly effective minimally invasive procedure to treat the painful effects of metastatic bone disease by injecting bone cement to support weakened bones-provides immediate and substantial pain relief, often presenting individuals who are suffering terribly with the miraculous so-called "Lazarus effect," according to researchers at the Society of Interventional Radiology's 34th Annual Scientific Meeting.
New Model Developed to Estimate Radiation Skin Doses during CT Guided Interventional Procedures
A new model that would allow interventional radiologists (radiologists who specialize in fine needle aspiration, fine needle biopsy and radiofrequency ablation) to better estimate patient radiation skin doses during CT guided interventional procedures has been developed.
Compiling Multiple CT Scans Simplifies Probe Repositioning During Radiofrequency Ablation
Merging multiple CT images (summation of CT scans) increases the accuracy of probe repositioning during radiofrequency ablation treatments of various lesions, according to a recent study performed at Dartmouth-Hitchcock Medical Center in Lebanon, NH.
Radiofrequency ablation is effective treatment for dysplasia in Barrett's esophagus
Interim results from a nationwide clinical trial led by a University of North Carolina at Chapel Hill researcher suggest that radiofrequency ablation is an effective treatment for dysplasia in people with Barrett's esophagus, a condition that can lead to deadly gastrointestinal cancer.

Radiofrequency Catheter Ablation of Cardiac Arrhythmias: Basic Concepts and Clinical Applications by Shoei K. Stephen Huang MD (Editor), David J. Wiber MD (Editor) A conceptual revolution in the field of cardiac ablation has been underway for several years, highlighted by an increased understanding of the structural basis of arrhythmias, and translation of this knowledge into effective anatomically-based ablation strategies. Since the publication of the first edition of this book in 1994, the scope, techniques and tools of radiofrequency ablation of arrhythmogenic tissue have evolved dramatically. This completely revised second edition provides a comprehensive description of the most up-to-date developments in radiofrequency catheter ablation of arrhythmias, from basic concepts to clinical applications. Fully two-thirds of the chapters are new for this edition, with the remainder having been extensively updated and rewritten. Part 1 is... |
