PURPOSE To evaluate the technical success and initial clinical safety and effectiveness of the use of a Y-shaped metallic stent for complex stenoses involving the carina. MATERIALS AND METHODS Thirty-five consecutive patients with complex tracheobronchial stenoses involving the carina were treated with an integrated self-expandable inverted Y-shaped(More)
PURPOSE To prospectively evaluate noncontrast-enhanced (NCE), time resolved, four-dimensional (4D) magnetic resonance angiography (MRA) for assessment of cerebral arteriovenous malformation (AVM), with intraarterial digital subtraction angiography (DSA) performed as the reference standard. MATERIALS AND METHODS Fifteen patients (ten men, five women; age(More)
This study aimed at assessing the usefulness of flat detector cone-beam CT virtual navigation-guided transthoracic needle biopsy of small (≤2.0 cm) pulmonary nodules in terms of diagnostic accuracy and complications to evaluate the diagnostic performance and complications of small pulmonary nodules under cone-beam CT (CBCT) guidance. A total of 100 patients(More)
BACKGROUND Nowadays, flat detector (FD) equipped angiographic C-arm computed tomography (CACT) systems can be used to acquire CT-like cross-sectional images directly within the interventional suite. The CACT systems offer real time visualization of transthoracic needle biopsy (TNB) procedure and more flexibility in the orientation of the detector system(More)
AIM To evaluate the mid-term safety and efficacy of a retrieval stent filter and 30mm balloon dilator in the treatment of Budd-Chiari syndrome (BCS) patients with chronic inferior vena cava (IVC) thrombosis. MATERIALS AND METHODS Twenty-three consecutive patients with BCS and chronic IVC thrombosis were treated with a retrieval stent filter and a 30mm(More)
PURPOSE This paper reports our initial experience with an integrated, self-expandable, Y-shaped, metallic stent (SEMS) for patients with complex anastomotic obstructions after gastrojejunostomy (Billroth II). MATERIALS AND METHODS Eight consecutive patients with complex anastomotic obstructions involving the afferent and efferent loops after(More)
BACKGROUND To explored the value of 3D C-arm CT (CACT) guidance system in performing radiofrequency ablation (RFA) following transarterial chemoembolizationon (TACE) for hepatocellular carcinomas. MATERIALS AND METHODS RFA of hepatocellular carcinomas (HCC) were performed on 15 patients (21 lesions) with the assistance of CACT guidance system. Technical(More)
The purpose of this study was to evaluate the usefulness of flat detector cone-beam CT-guided CBCT percutaneous needle biopsy (PNB) of mediastinal lesions. A total of 100 patients with 100 solid mediastinal lesions were retrospectively enrolled to undergo percutaneous needle biopsy (PNB) procedures. The mean diameter of lesions was 4.4 ± 1.8 cm (range(More)
AIM To evaluate the type of venous involvement in Chinese Budd-Chiari syndrome (BCS) patients and the relative diagnostic accuracy of the different imaging modalities. METHODS Using digital subtraction angiography (DSA) as a reference standard, color Doppler ultrasound (CDUS), computed tomography angiography (CTA), and magnetic resonance angiography (MRA)(More)
