OBJECTIVE To investigate the effect of percutaneous drainage on liver hydatid cysts. DESIGN A retrospective case study. SETTING Department of Surgery, Selçuk University, Konya, Turkey. PATIENTS Forty-five patients with 83 liver hydatid cysts (types I and II according to the classification of Gharbi and colleagues) followed up for a mean of 30 months (range from 14 to 36 months). INTERVE...
387 are malignant.[2] The large ovarian cyst can undergo torsion at any time leading to acute abdominal pain and necrosis of the ovary. Patients are also at risk of developing sepsis due to torsion. Massive ovarian cyst hemorrhage can occur in anticoagulated patients, including those on hemodialysis, who receive heparin anticoagulation.[3] Such cyst may rupture accidentally during continuous am...
A 68-year-old woman had a solitary 12.0 cm hepatic cyst with a septum. The cyst was located near the hepatic hilum and she presented with obstructive jaundice caused by compression of the hilar bile duct. Stenosis of the common hepatic duct was detected at the porta hepatis on endoscopic retrograde cholangiography (ERC), and encasement of the right hepatic artery at the same level was revealed ...
Ultrasonography (US) features of thyroid nodules can be helpful in identifying those most at risk for malignancy; these include marked hypoechogenicity, microcalcifications, irregular margins, and a taller-than-wide shape (nonparallel orientation). Some cystic change morphologically after simple aspiration percutaneous ethanol injection treatment. They show hypoechogenicity margins on the US di...
Percutaneous radiofrequecy ablation (RFA) is becoming a standard minimal invasive procedure in the clinical routine. However, the control of shape and size of the ablation zone is unsatisfactory, especially close to large vessels. In this work, our aim is to present a novel image based, fast approximation of the ablation zone with respect to the cooling blood flow, which decreases thermal ablat...
