AIM To comparatively evaluate Seldinger and Trocar techniques in the percutaneous treatment of hydatid disease. METHODS Trocar and Seldinger techniques were used for 49 and 56 cysts, respectively, among 106 hydatid cysts in 88 patients. The number of males and females were 22 and 66, respectively with a mean age of 44.9 years (range, 15-87). Follow-up studies included cyst diameter, cyst cont...
PURPOSE To describe our initial experience with radiofrequency ablation (RFA) of Bosniak IV renal cysts. MATERIALS AND METHODS From 2010 to 2014, 154 renal tumor cases were treated with percutaneous thermal ablation, of which 10 cases (6.4%) from nine patients were complex renal cysts and were treated with radiofrequency ablation. RESULTS All complex cysts were classified as Bosniak IV (fou...
A 56-year-old woman visited our hospital because of high fever and right hypochondralgia. Abdominal computed tomography showed a liver cyst 10 cm in diameter and dilatation of the intrahepatic bile duct. Percutaneous transhepatic drainage of the cyst guided by ultrasonography disclosed that the cyst contained a brown milky fluid, and cystography showed biliary communication. Thus, the cyst was ...
At the time of antiarrhythmic surgery, cryothermal energy application by a hand-held probe was used to complement dissections and resections and permanently abolish the arrhythmogenic substrate. Over the last decade, significant engineering advances allowed percutaneous cryoablation based on catheters, apparently not very different from standard radiofrequency ablation catheters. Cryothermal en...
BACKGROUND Ventricular tachycardia (VT) refractory to antiarrhythmic drugs and standard percutaneous catheter ablation techniques portends a poor prognosis. We characterized the reasons for ablation failure and describe alternative interventional procedures in this high-risk group. METHODS AND RESULTS Sixty-seven patients with VT refractory to 4±2 antiarrhythmic drugs and 2±1 previous endocar...
PURPOSE To investigate the efficacy and safety of percutaneous microwave ablation. METHODS Twenty-six rabbits with lung VX2 tumor were randomly divided into experimental and control group. In the experimental group, microwave ablation guided by ultrasound or CT was performed based on location of the tumor. Enhanced CT scan was carried out immediately before and after the ablation for all anim...
PURPOSE A comprehensive review of the literature in order to analyze data about the success rate of percutaneous resolution of the lumbar facet joint cysts as a conservative management strategy. METHODS A systematic search for relevant articles published during 1980 to May 2014 was performed in several electronic databases by using the specific MeSH terms and keywords. Most relevant data was ...
A 49-year-old man with a history of acute pancreatitis was hospitalized with a diagnosis of pancreatic pseudocyst. Ultrasonography, computed tomography, and magnetic resonance imaging all demonstrated a homogeneous cyst, 9 x 4 cm in size, at the tail of the pancreas without mural nodules or septa. Because an intestinal structure was identified between the cyst and stomach preoperatively by comp...
