The aim of this study was to analyze clinical and anatomical factors affecting the pathologic quality of the resected specimen after total mesorectal excision (TME) for rectal cancer. A total of 100 patients who underwent TME for mid or low rectal cancer were evaluated prospectively. MRI pelvimetry data (transverse diameter, obstetric conjugate,(More)
Background: Preoperative staging is essential for planning of optimal therapy for patients with rectal cancer. Recently, magnetic resonance imaging (MRI) is used frequently because of its benefits of clear pelvic image are better than other diagnostic methods. The purpose of this study was to determine accuracy rates and clinical usefulness of MRI in(More)
The purpose of this study was to evaluate the classification of persistent primitive trigeminal artery (PPTA) based on computed tomography (CT) angiography, magnetic resonance (MR) angiography, and cerebral angiography and to review the clinical significance. Images obtained by CT angiography performed between January 2011 and August 2013, MR angiography(More)
OBJECTIVE The objective of our study was to determine the feasibility of using Metal Artifact Reduction (MAR) software for abdominopelvic dual-energy CT in patients with metal hip prostheses. MATERIALS AND METHODS This retrospective study included 33 patients (male-female ratio, 19:14; mean age, 63.7 years) who received total hip replacements and 20(More)
PURPOSE The aim of this study was to evaluate the feasibility and safety of the transfacial venous embolization of cavernous or paracavernous dural arteriovenous fistula (DAVF) in which approach via inferior petrosal sinus (IPS) was not feasible. MATERIALS AND METHODS We identified the cases of transfacial venous embolization of cavernous sinus (CS) or(More)
Although lumbosacral lipoma is reported to occur in 4-8 of 100,000 patients, and 66% of lipomyelomeningoceles in young patients are accompanied by hypertrophic filum terminale, it is very rare to find two isolated spinal lipomas simultaneously. A 3 month-old baby girl was admitted to the hospital for a protruding, non-tender, soft, subcutaneous 2.5 cm mass(More)
Blood blister-like aneurysms (BBAs) are difficult to treat both surgically and endovascularly, and the optimal treatment remains controversial. The aim of this study was to evaluate the clinical and angiographic feasibility of multiple overlapping stents (≥3) with coiling for treating BBA. A retrospective review from four institutions identified ten(More)
OBJECTIVE Intracranial stenting for stent-assisted coiling of aneurysms requires adequate follow-up imaging. The aim of this in vitro study was to compare in-stent artificial luminal narrowing on contrast-enhanced MR angiograms (CE-MRA) when applying Neuroform® and Enterprise® stents for stent-assisted coiling. MATERIALS AND METHODS Two intracranial(More)
The pipeline embolization device (PED) is a new endovascular device for treatment of complex, fusiform and wide-neck intracranial aneurysms. The main mechanism of this stent is to divert the flow in the parent artery with reduction of inflow in the aneurysm leading to thrombosis. We treated a 40-year-old woman who had left facial pain and orbit discomfort.(More)
A rhabdoid cholangiocarcinoma is a very rare variant of sarcomatous cholangiocarcinomas. Here, we report a vimentin positive cholangiocarcinoma showing rhabdoid features in the entire tumor, with a very aggressive behavior. A 41-year-old woman was admitted to our hospital due to a huge hepatic mass. The resected liver revealed a 17 x 15 cm sized solid mass(More)
