OBJECTIVE The purpose of this study was to prospectively evaluate pathologic responses to transarterial prostatic embolization and its technical safety in a canine model. MATERIALS AND METHODS Ten adult male beagle dogs were surgically castrated and given hormonal therapy for 4 months to induce prostatic hyperplasia. After three months of hormonal therapy, the dogs were randomly assigned to a...

BACKGROUND AND PURPOSE Transarterial detachable balloon embolization of direct carotid cavernous fistulas (DCCFs) has become an optimal treatment. In a few cases, the parent artery has to be sacrificed to achieve morphologic cure. We present our experience with transarterial balloon-assisted n-butyl-2-cyanoacrylate (n-BCA) embolization of DCCFs in which there was failure to achieve angiographic...

OBJECTIVE Treatment of intracranial dural arteriovenous fistulas (dAVFs) remains a challenge. However, after introduction of Onyx, transarterial approach is the preferred treatment option in many centers. We report our experience of dAVFs embolization with special emphasis on transarterial approach. METHODS Seventeen embolization procedures were performed in 13 patients with dAVFs between Jan...

A boy was born at 36 weeks gestation weighing 2,135 g, with a prenatal diagnosis of dural sinus malformation with arteriovenous shunts. Congestive heart failure and anuria at birth prompted emergency intervention. Transfemoral-transvenous coil embolization was performed on day 1, resulting in partial occlusion of the huge venous pouch with a total length of 2,355 cm of detachable coils. Transar...

To examine the outcomes of patients treated with combination therapy transarterial ethanol and Lipiodol embolization percutaneous microwave ablation unresectable intermediate to large-sized hepatocellular carcinoma. This an IRB-approved retrospective study. From January 2018- October 2018, 20 (16M, 4 F, ages 51-85, Mean age 67) carcinoma (HCC) solitary lesions less than 6 cm (3.1–6.0 cm, median...

a 52-year-old post-menopausal female was admitted to the emergency room due to acute onset of abdominal pain in the right lower quadrant. there was no history of trauma of the abdomen. contrast-enhanced multi-detector computed tomography (mdct) of the abdomen and pelvis revealed a massive right retroperitoneal hematoma and contrast extravasation from a right ovarian artery aneurysm. digital sub...

A 48-year-old man with a history of splenic artery pseudoaneurysm requiring transarterial embolization 3 months earlier presented to the emergency department with abdominal pain and fever. Computed tomography showed evidence of embolization coil fragments within the gastrointestinal tract. Upper endoscopy showed a large gastric ulcer with numerous embolization coils extruding into the gastric l...

Metastatic tumors are the most common malignancy of bone. Many patients with spinal metastases present with pain and pathologic fractures. The advent of interventional radiology resulted in alternative and less invasive treatment of these patients. This article presents minimally invasive (percutaneous) procedures that are currently in use, i.e. vertebroplasty, kyphoplasty, osteoplasty, radiofr...

Early detection of metastatic disease within the liver by advanced diagnostic imaging has driven the rise of image-guided intervention for hepatic metastases. In this talk, we will explore the rationale, indications, technique and post procedure imaging findings of percutaneous treatments of liver metastases. Curative intent ablative therapies, such as radiofrequency ablation, microwave ablatio...

OBJECTIVES/HYPOTHESIS To present our 8-year experience with transarterial embolization for head and neck bleeding, with an emphasis on the need for repeated procedures in patients treated for head and neck cancer. STUDY DESIGN Retrospective case series. METHODS Tertiary university-affiliated medical center. The cohort included 49 patients who underwent transarterial embolization for acute h...
