Downstaging unresectable hepatocellular carcinoma by radioembolization using 90-yttrium resin microspheres: a single center experience.

Background: Only one third of patients with hepatocellular carcinoma can benefit from curative treatments at the time of first diagnosis. Tumor downstaging by radioembolization may enable initially unresectable hepatocellular carcinoma (HCC) to be treated with surgery lengthening survival.

Methods: From June 2011 through June 2014, all patients with a first diagnosis of unresectable HCC with intrahepatic portal vein thrombosis were treated in our center with radioembolization using 90-yttrium resin microspheres.

Disconnection of multilayer stents 2 years after treatment of a hepatic artery aneurysm.

Purpose: To report midterm failure of tandem peripheral multilayer stents used to treat a common hepatic artery aneurysm (HAA) that had a good early result.

Case Report: A 71-year-old man with multiple comorbidities had a 3.4-cm HAA treated with 2 Cardiatis peripheral multilayer stents (8×100 and 9×60 mm) that overlapped by 3 cm.

Symptomatic aneurysm of a perforating peroneal artery after a blunt trauma.

A 48-year-old woman was referred to us for a pulsatile and painful mass on the right leg after a trauma occurred 2 months earlier. The duplex scan revealed the presence of an aneurysm of the perforating peroneal artery. The patient underwent an endovascular coil embolization of the aneurysm.

Endovascular treatment of a symptomatic mycotic aneurysm of the peroneal artery.

A 69-year-old man was referred to our facility owing to the sudden onset of a compression-like pain in the right leg, without limb-threatening acute ischemia. The duplex scan examination, followed by a selective leg angiography, showed the presence of a peroneal artery aneurysm. A diagnosis of mycotic aneurysm was made on the basis of the patient's clinical condition, positive blood cultures, and the unusual location of the lesion.

Safety and efficacy of the percutaneous treatment of bile leaks in hepaticojejunostomy or split-liver transplantation without dilatation of the biliary tree.

Biliary leaks complicating hepaticojejunostomy (HJA) or fistulas from cut surface are severe complications after liver transplantation (LT) and split-liver transplantation (SLT). The aim of the study was to describe our experience about the safety and efficacy of radiological percutaneous treatment without dilatation of intrahepatic biliary ducts. From 1990 to 2006, 1595 LTs in 1463 patients were performed in our center.

Experiences in US-guided percutaneous radiofrequency ablation of 44 renal tumors in 31 patients: analysis of predictors for complications and technical success.

Purpose: Preliminary clinical studies have shown the feasibility, safety, and efficacy of radiofrequency thermal ablation (RFA) of renal tumors, but only a few have analyzed the prognostic factors for technical success and there are no long-term results. Our objective was to statistically evaluate our mid-term results of percutaneous US-guided RFA in order to define predictors for complications and technical success.

Methods: We selected for treatment 44 tumors in 31 patients (24 with renal cell carcinoma, 7 with hereditary tumors, 15 with a solitary kidney), up to 5 cm in diameter.
