Angiosarcoma is a rare type of soft tissue sarcoma that accounts for less than 1% of all sarcomas and only 2% of all primary hepatic tumours. Thorotrast, arsenic, and vinyl chloride monomer are frequently listed as occupational exposure risks. The estimated latency is long (10-40 years) in occupational cases and very long (60 years or more) in non-occupational cases. The symptoms and CT-scan appearance of hepatic angiosarcoma (HAS) are non-specific. We present a case of a 65-year-old Caucasian male with history of cryptogenic cirrhosis, low alpha-foetoprotein levels and a single, 4-cm nodule of potential atypical hepatocellular carcinoma (no washout at MRI and CT-scan) in segment VIII...

Nathan W Kugler, Kellie R Brown
BACKGROUND: Chronic venous insufficiency affects millions of Americans with symptoms spanning a broad range. Saphenous incompetence resulting in chronic reflux is at the root of most disease and is amenable to surgical correction. METHODS: We conducted a systematic review of the literature on nonthermal ablative techniques using a MEDLINE (Ovid) search from January 2000 to August 2016. Only prospective studies and literature review articles in the English language were included for final analysis...

OBJECTIVE: Endothermal heat-induced thrombosis (EHIT) is a known complication of endothermal venous ablation procedures. EHIT can lead to deep vein thrombosis/pulmonary embolism, which cause significant disability and, rarely, death. Other studies have evaluated risk factors for EHIT. There is an accepted grading system for EHIT, but there is no consensus on treatment type, duration, or follow-up. We retrospectively evaluated all cases of EHIT after radiofrequency ablation or endovenous laser ablation at our institution during a 7-year period, focusing on classification, treatment, and outcomes of EHIT...

Background The development and use of minimally invasive procedures provide improved options for the management of symptoms of chronic venous insufficiency. While many patients with iliac venous occlusive disease and superficial venous insufficiency improve with combined iliac venous stenting and correction of superficial venous reflux, some patients have symptoms which persist. The goal of this study was to identify clinical factors related to persistent symptoms in patients with leg swelling after treatment of both iliac vein stenting and thermal ablation...

A 27-year-old female patient was referred due to an edematous left lower extremity. Both saphenous veins had been ablated with an endovenous laser procedure used to treat varicose veins. Venography revealed that the left common femoral vein had been divided and that thrombosis was present at the site of division. No veins were available around the thighs. The patient was treated using a staged procedure. During the first stage, a ringed polytetrafluoroethylene graft was used to repair the common femoral vein, and an arteriovenous fistula was constructed from the femoral artery to the graft using a short segment of cephalic vein to increase graft patency...

Aims: Measurement of circulating biomarkers of fibrosis may have a role in selecting patients and treatment strategy for catheter ablation. Pro-collagen type III N-terminal pro-peptide (PIIINP), C-telopeptide of type I collagen (ICTP), fibroblast growth factor 23 (FGF-23), and galectin 3 (gal-3) have all been suggested as possible biomarkers for this indication, but studies assessing whether peripheral levels reflect intra-cardiac levels are scarce. Methods and results: We studied 93 patients undergoing ablation for paroxysmal atrial fibrillation (AF) (n = 63) or non-paroxysmal AF (n = 30)...

Aims: Initiating mechanisms of atrial fibrillation (AF) remain poorly understood, involving complex interaction between triggers and the atrial substrate. This study sought to classify the transitional phenomena, hypothesizing that there is consistency within and between patients in trigger-substrate interaction during transition to AF. Methods and results: Non-contact left atrial (LA) mapping was performed in 17 patients undergoing ablation for paroxysmal AF. All had spontaneous ectopy...

Atrial fibrillation is the most common cardiac arrhythmia. The development of electroanatomical mapping is an increase demand for advanced intracardiac imaging techniques of the left atrium and pulmonary veins. IVUS can demonstrate quantitative changes like lumen and wall thickness as well as qualitative changes of the pulmonary wall. IVUS could also provide relevant real time imaging of the atrial and pulmonary venous wall during catheter ablation. Areas covered: The Medline and Embase databases were searched for preclinical and clinical studies of IVUS in patients with ablation of atrial fibrillation or left atrial arrhythmias...

Most tachycardias in the pulmonary venous atrium are inaccessible by direct means and require either a retrograde approach or a transseptal approach for ablation. We present a case in which successful radiofrequency ablation of common atrioventricular nodal reentrant tachycardia was accomplished via a retrograde transaortic approach guided by nonfluoroscopic mapping with use of the NavX(™) mapping system. The patient was a 49-year-old woman who at the age of 4 years had undergone Mustard repair for complete dextrotransposition of the great arteries...

Adults who underwent complex atrial baffling as children via Mustard or Senning procedures are at heightened risk for atrial arrhythmias. Antiarrhythmic therapies are typically ineffective in this population. Accordingly, our team of pediatric and adult electrophysiologists investigated the effectiveness of early invasive transbaffle-access techniques to perform early radiofrequency ablation at the source of these clinically significant arrhythmias. For this retrospective study, we selected 11 adult survivors of atrial baffling (mean age, 34 ± 9 yr) who underwent clinically indicated electrophysiologic study after no more than one trial of antiarrhythmic therapy...
