Simultaneous transarterial chemoembolization and radiofrequency ablation for large hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is a common cancer and a leading cause of tumor-related death. Patients with large HCC (≥ 8 cm) are at an advanced stage and have poor prognosis, and hepatic resection may not be suitable, and the incidence of postoperative recurrence is high.

Aim: To evaluate recurrence and mid-term survival of patients with large HCC treated by transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA).

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).

Seminal vesicle abnormalities following prostatic artery embolization for the treatment of benign prostatic hyperplasia.

Background: Prostatic artery embolization (PAE) has been proved effective in the treatment of lower urinary tracts (LUTS) secondary to benign prostatic hyperplasia (BPH) with low complications, and most of the them are due to non-target embolization of adjacent organs, such as bladder, rectum, seminal vesicles and penis. Aim of this study was to present seminal vesicle (SV) abnormalities following prostatic artery embolization (PAE) for the treatment of symptomatic benign prostatic hyperplasia.

Methods: We reviewed 139 BPH patients who received PAE during the period of February 2009 and January 2015 at a single institution, highlighting seminal vesicle abnormalities and their clinical relevance after PAE.

CT during celiac artery angiography for localization of clinically suspected small insulinomas.

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.
