OBJECTIVE: Thermoablation has been replacing conventional surgery in the surgical treatment of great saphenous vein (GSV) reflux in patients with lower limb varicose veins; however, thermoablation is expensive. Intravenous electrocoagulation (EC) may, selectively and safely, cause necrosis of the GSV wall, but the clinical results have never been studied. The objective of this study was to compare EC and radiofrequency ablation (RFA) in the treatment of GSV insufficiency, considering efficacy, complications, and effect on quality of life...

Introduction: Coronary sinus (CS) is the largest vein draining the blood from heart. It is a muscular tube of about 2 cm to 3 cm length and 1 cm in caliber. It has become a clinically important structure through its role in providing access for different cardiac procedures viz., biventricular pacing, arrhythmia ablation and for deployment of an array of cardiac devices. Aim: To study the location, shape, length and width of CS including its left atrial muscular coverage in 50 cadaveric hearts...

INTRODUCTION: Limited data exists for types of venous closure and its associated complications in patients after atrial fibrillation (AF) catheter ablation. We evaluated the subcutaneous figure-of-eight closure (FO8) for achieving venous hemostasis after AF catheter ablation compared to manual pressure. METHODS: 284 consecutive patients that underwent AF catheter ablation by two operators were included. All patients received continuous therapeutic warfarin or interrupted novel oral anticoagulants (NOAC) and heparin (ACT300-400 s) without reversal...

Reconstruction of soft tissue defects in the foot remains a challenge due to its specialized tissue for weightbearing and ambulation. Considering the principle of replacing "like with like," adjacent soft tissues would be a best option for a donor site. Although several kinds of reverse-flow island flaps for the lower leg have been well described, intrinsic foot reverse flow flaps have been rarely reported. We describe 3 kinds of reverse-flow intrinsic fasciocutaneous flaps (RIFFs) for foot reconstruction. From September 2012 to August 2015, a retrospective study was done on case notes of all patients who had a RIFF for coverage of soft tissue defects within the foot following trauma or tumor ablation...

The pulmonary veins carry oxygenated blood from the lungs to the heart, but their importance to the radiologist extends far beyond this seemingly straightforward function. The anatomy of the pulmonary veins is variable among patients, with several noteworthy variant and anomalous patterns, including supernumerary pulmonary veins, a common ostium, anomalous pulmonary venous return, and levoatriocardinal veins. Differences in pulmonary vein anatomy and the presence of variant or anomalous anatomy can be of critical importance, especially for preoperative planning of pulmonary and cardiac surgery...

Cardiac magnetic resonance (CMR) is a non-invasive, non-ionizing, diagnostic technique that uses magnetic fields, radio waves and field gradients to generate images with high spatial and temporal resolution. After administration of contrast media (e.g., gadolinium chelate), it is also possible to acquire late images, which make possible the identification and quantification of myocardial areas with scar/fibrosis (late gadolinium enhancement, LGE). CMR is currently a useful instrument in clinical cardiovascular practice for the assessment of several pathological conditions, including ischemic and non-ischemic cardiomyopathies and congenital heart disease...

BACKGROUND: Interferon-based antiviral therapies against hepatitis C virus (HCV) infection have been shown to reduce the incidence of hepatocellular carcinoma (HCC) in patients with sustained viral response (SVR). Recently, direct-acting antivirals (DAAs) have been proven to be much more effective in achieving SVR than interferon-based therapies. However, whether DAAs can efficiently prevent the occurrence of HCC after SVR remains controversial. To clarify this issue, we analyzed the clinical features of patients in whom HCC developed after achievement of SVR with DAAs for chronic HCV infection...

BACKGROUND: Endothermal treatment of the great saphenous vein (GSV) has become the first-line treatment for superficial venous reflux. Nonthermal ablation has potential benefits for acceptability by patients and decreased risk of nerve injury. We performed a systematic review and meta-analysis to evaluate the efficacy of mechanochemical endovenous ablation (MOCA) and cyanoacrylate vein ablation (CAVA) for GSV incompetence. METHODS: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane databases were searched for papers published between January 1966 and December 2016...

BACKGROUND: Routine radiofrequency ablation (RFA) of an incompetent perforator vein (IPV) using the standard treatment protocol at 85°C has a treatment time of 6 minutes. To make treatment time more efficient, we sought to determine the effect of a shortened protocol for radiofrequency stylet (RFS) ablation by comparing the early success using three different temperatures: 85°C, 90°C, and 95°C. METHODS: A retrospective study examined 642 procedures of IPV closures in 255 patients with varying degrees of venous insufficiency treated with RFA from 2009 to 2015...

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome clinically characterized by bone pain, fractures and muscle weakness. It is caused by tumoral overproduction of fibroblast growth factor 23 (FGF23) that acts primarily at the proximal renal tubule, decreasing phosphate reabsorption and 1α-hydroxylation of 25 hydroxyvitamin D, thus producing hypophosphatemia and osteomalacia. Lesions are typically small, benign mesenchymal tumors that may be found in bone or soft tissue, anywhere in the body...

Chronic venous insufficiency is characterized by cutaneous alterations caused by venous hypertension; in severe forms, it progresses to lower limb ulcers. Lower limb varicose veins are the main cause of chronic venous insufficiency, and the classic treatment includes surgery and compressive therapy. Minimally invasive alternative treatments for varicose veins include new techniques such as venous thermal ablation using laser or radiofrequency. The use of different methods depends on clinical and anatomical factors...

Background: Intra-atrial re-entrant tachycardia (IART) is a frequent and severe complication in patients with congenital heart disease (CHD). Cavotricuspid isthmus (CTI)-related IART is the most frequent mechanism. However, due to fibrosis and surgical scars, non-CTI-related IART is also frequent. Objective: The main objective of this study was to describe the types of IART and circuit locations and to define a cut-off value for unhealthy tissue in the atria. Methods and results: This observational study included all consecutive patients with CHD who underwent a first ablation procedure for IART from January 2009 to December 2015 (94 patients, 39...
