OBJECTIVE The purpose of this study was to subdivide the types of sonographic findings of benign versus malignant cystic masses and to determine appropriate patient care according to the sonographic findings with pathologic correlation. METHODS The sonographic findings of 175 symptomatic cystic breast lesions were pathologically proven and reviewed(More)
OBJECTIVE The purpose of this study was to evaluate our experience with the use of a Rösch-Uchida needle technique to recanalize central vein occlusion that cannot be traversed with a guidewire. MATERIALS AND METHODS We retrospectively evaluated 33 recanalization procedures performed with a Rösch-Uchida needle on 20 men and 13 women with central vein(More)
INTRODUCTION A hepatic subcapsular hematoma in a neonate shows a non-specific presentation such as the presence of an abdominal mass without symptoms of hemorrhage and is clinically less distinguished as compared to cases detected during an autopsy. CASE PRESENTATION A neonate was delivered by vaginal delivery after 29 weeks and three days gestation with(More)
Interstitial ectopic pregnancy is a rare condition of pregnancy and may be very dangerous if not identified and treated urgently. We report a case of successful treatment of an interstitial pregnancy using selective uterine artery embolization. A 27-year-old woman with interstitial pregnancy was treated by uterine artery embolization after failure of(More)
BACKGROUND Prognostic factors of breast cancer have been used for the prediction of clinical outcome or selection of patients for complementary treatment. Some of the imaging features of breast cancer, e.g. magnetic resonance imaging (MRI), are associated with these prognostic factors. PURPOSE To evaluate the relationship between dynamic enhanced MR(More)
PURPOSE The purpose of this study was to evaluate the feasibility, efficacy and safety of percutaneous thromboaspiration with a 7F Desilets-Hoffman sheath compared with previously established percutaneous mechanical thrombectomy techniques in occluded hemodialysis grafts. MATERIALS AND METHODS One thousand three hundred five patients (767 women, 538 men;(More)
PURPOSE We aimed to evaluate the effectiveness of the Fogarty balloon application in dislodging residual thrombus at the sheath entry point in a graft by using single apex puncture to declot thrombosed hemodialysis loop grafts. MATERIALS AND METHODS The apex puncture technique was used in 520 cases to declot 376 hemodialysis loop grafts (male/female,(More)
Endovascular procedures are becoming the standard type of care for the management of hemodialysis vascular access dysfunction. As with any type of medical procedure, these techniques can result in procedure-related complications, although the expected number of complications is low. The clinical extent of these complications varies from case to case.(More)
The chronic toxic effects of major heavy metals including copper (Cu), zinc (Zn), lead (Pb), and cadmium (Cd) on the filtration rate (FR), sex ratio, and gonad development of immature blood clams, Tegillarca granosa, were investigated. The FRs were significantly inhibited by Cu, Pb and Cd, with rates generally decreasing with both increasing metal(More)
the most serious and potentially life-threatening complication associated with preeclampsia or eclampsia. The patient’s survival generally depends on the early recognition of the characteristic signs and symptoms and prompt surgical intervention. Even with surgical intervention, the maternal mortality had been reported to be as high as 59-86% (1, 2). We(More)
