Heparin-bonded stent graft placement for treatment of massive epistaxis from ruptured radiation-induced internal carotid artery pseudoaneurysm: A case report.

Rupture of an internal carotid artery (ICA) pseudoaneurysm is a rare but life-threatening complication of irradiation therapy for a nasopharyngeal carcinoma (NPC). A 36-year-old man had a history of NPC treated with radiotherapy 8 years previously. He was admitted to the hospital because of severe repetitive epistaxis with hemodynamically instablility.

Effectiveness of Contrast-enhanced MR Angiography for Visualization of the Prostatic Artery prior to Prostatic Arterial Embolization.

Background A major technical challenge of prostatic arterial embolization (PAE) is the identification and catheterization of the prostatic arteries (PAs). Recently, MR angiography has been shown to help visualize PAs, but the clinical utility of MR angiography for this purpose is not known. Purpose To determine the efficacy of contrast material-enhanced MR angiography in identifying the PA and to evaluate its role in PAE for benign prostatic hyperplasia (BPH).

Comparison of Clinical Outcomes of Prostatic Artery Embolization with 50-μm Plus 100-μm Polyvinyl Alcohol (PVA) Particles versus 100-μm PVA Particles Alone: A Prospective Randomized Trial.

Purpose: To evaluate the safety and efficacy of prostatic artery embolization (PAE) using the combination of 50-μm and 100-μm polyvinyl alcohol (PVA) particles versus 100-μm PVA particles alone in the treatment of patients with symptomatic benign prostatic hyperplasia (BPH).

Materials And Methods: Over a 5-year period, 120 patients treated with PAE for lower urinary tract symptoms (LUTS) secondary to BPH were randomized to undergo embolization with 50-μm plus 100-μm PVA particles (group A) or 100-μm PVA particles alone (group B). Mean follow-up time was 34 months (range, 12-57 mo).

Combined transcatheter arterial chemoembolization and radiofrequency ablation in single-session for solitary hepatocellular carcinoma larger than 7 cm.

Aims: To evaluate technical feasibility and treatment results of combined transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) in single-session for solitary hepatocellular carcinoma (HCC) larger than 7 cm in diameter.

Methods: Institutional review board approved this retrospective study. Written informed consent was obtained from all patients.

Transarterial Embolization for Treatment of Symptomatic Polycystic Liver Disease: More than 2-year Follow-up.

Background: Currently, treatment of symptomatic polycystic liver disease (PLD) is still a challenging problem, especially for these patients who are not feasible for surgery. Minimally invasive options such as laparoscopic fenestration and percutaneous cyst aspiration with sclerotherapy demonstrated disappointing results due to multiple lesions. Because the cysts in PLD are mostly supplied from hepatic arteries but not from portal veins, transcatheter arterial embolization (TAE) of the hepatic artery branches that supply the major hepatic cysts can lead to shrinkage of the cyst and liver size, relieve symptoms, and improve nutritional status.
