Transcatheter Embolization of High-flow Renal Arteriovenous Fistula Using N-butyl Cyanoacrylate Accompanied by Delayed Hydronephrosis.

Renal arteriovenous fistula (AVF) is an uncommon anomaly characterized by the communication between renal arteries and veins. Renal AVFs are often asymptomatic but are occasionally accompanied by hematuria or heart failure. Transcatheter closure with embolization is a safe and effective treatment for renal AVF.

Provocative Endoscopy to Identify Bleeding Site in Upper Gastrointestinal Bleeding: A Novel Approach in Transarterial Embolization.

This report describes a novel approach to endoscopically induce bleeding by removing a clot from the bleeding site during angiography for upper gastrointestinal (UGI) hemorrhage. This procedure enabled accurate identification of the bleeding site, allowing for successful targeted embolization despite a negative initial angiogram. Provocative endoscopy may be a feasible and useful option for angiography of obscure bleeding sites in patients with UGI arterial hemorrhage.

Contrast-enhanced MRI for detecting intravertebral cleft formation: relation to the time since onset of vertebral fracture.

Objective: The purpose of this study was to investigate the advantages of contrast-enhanced MRI (CE-MRI) for detecting intravertebral clefts over unenhanced MRI in relation to the time since onset of vertebral fracture.

Materials And Methods: In this retrospective study, a total of 115 patients (88 women, 27 men; mean age, 77.1 years) who underwent percutaneous vertebroplasty for a single-level compression fracture within 7 days of preprocedural MRI were enrolled.

Prognosis of patients with hepatocellular carcinoma treated solely with transcatheter arterial chemoembolization: risk factors for one-year recurrence and two-year mortality (preliminary data).

Objective: Transcatheter arterial chemoembolization (TACE) is an essential therapy for patients with hepatocellular carcinoma (HCC) in whom administering other treatments such as liver transplantation, resection or local therapy is not feasible. The purpose of our study was to determine the independent risk factors for one-year recurrence and two-year mortality in patients treated solely with TACE.

Methods: We conducted a retrospective cohort study of 34 consecutive patients (Group 1) with incident HCC who were treated solely with epirubicin-based TACE between April 2004 and March 2009.

Radiological findings as favorable predictors of pain relief in patients with osteoporotic compression fractures after percutaneous vertebroplasty: a retrospective study of 156 cases.

Purpose: We evaluated the relationships between pre-procedural radiological findings and short-term pain relief in patients with osteoporotic compression fractures after percutaneous vertebroplasty (PVP).

Materials And Methods: A retrospective review of pre-procedural radiological images of 156 patients with painful osteoporotic compression fracture was performed. Pain was measured with a visual analogue scale (VAS).

New vertebral compression fractures after prophylactic vertebroplasty in osteoporotic patients.

Objective: Previous studies have shown the possible efficacy of prophylactic cement injection for nonfractured vertebrae during percutaneous vertebroplasty for compression fractures. The purpose of this study was to investigate risk factors for subsequent fractures after prophylactic percutaneous vertebroplasty.

Materials And Methods: This retrospective study included 116 patients with osteoporotic compression fractures who underwent prophylactic percutaneous vertebroplasty.

Therapeutic effects of percutaneous vertebroplasty for vertebral metastases.

Purpose: We have performed percutaneous vertebroplasty (PV) using polymethylmethacrylate (PMMA) for patients with vertebral metastases since 2002. This study investigated the therapeutic effects of PV on vertebral metastases.

Materials And Methods: A retrospective (2002-2008) review was conducted for 69 consecutive patients with 141 metastatic vertebrae treated with PV using PMMA.

Prophylactic vertebroplasty: cement injection into non-fractured vertebral bodies during percutaneous vertebroplasty.

Rationale And Objectives: We investigated the efficacy of prophylactic cement injection into the vertebral body adjacent to fractured vertebra to prevent new fractures after percutaneous vertebroplasty (PV).

Materials And Methods: Between February 2002 to August 2004, PV was performed for osteoporotic compression fractures in 89 consecutive patients. All patients underwent PV for only fractured vertebrae.

Preprocedural MR imaging for percutaneous vertebroplasty: special interest in contrast enhancement.

Purpose: The success of percutaneous vertebroplasty (PVP) depends greatly on preprocedural evaluation of the patients. The purpose of this study was to evaluate the efficacy of preprocedural magnetic resonance imaging (MRI) for the indications of PVP.

Materials And Methods: A retrospective review of 122 osteoporotic compression fractures in 63 patients who underwent preprocedural gadolinium-enhanced MRI and PVP was performed.

Percutaneous pediculoplasty for vertebral hemangioma involving the neural arch: a case report.

Vertebral hemangiomas occasionally involve the neural arch and they can be symptomatic. We report a case of symptomatic vertebral hemangioma mainly involving the unilateral neural arch which was successfully treated with percutaneous pediculoplasty using a single-needle technique.
