Multicenter Study of Metastatic Lung Tumors Targeted by Interventional Cryoablation Evaluation (SOLSTICE).

Objective: To assess the safety and local recurrence-free survival in patients after cryoablation for treatment of pulmonary metastases.

Methods: This multicenter, prospective, single-arm, phase 2 study included 128 patients with 224 lung metastases treated with percutaneous cryoablation, with 12 and 24 months of follow-up. The patients were enrolled on the basis of the outlined key inclusion criteria, which include one to six metastases from extrapulmonary cancers with a maximal diameter of 3.

Early results from a United States trial of prostatic artery embolization in the treatment of benign prostatic hyperplasia.

Purpose: To report early findings from a prospective United States clinical trial to evaluate the efficacy and safety of prostatic artery embolization (PAE) for benign prostatic hyperplasia (BPH).

Materials And Methods: From January 2012 to March 2013, 72 patients were screened and 20 patients underwent treatment. Patients were evaluated at baseline and selected intervals (1, 3, and 6 mo) for the following efficacy variables: American Urological Association (AUA) symptom score, quality of life (QOL)-related symptoms, International Index of Erectile Function score, peak urine flow rate, and prostate volume (on magnetic resonance imaging at 6 mo).

Utility of cone-beam CT imaging in prostatic artery embolization.

Purpose: To evaluate the utility of cone-beam computed tomography (CT) in patients undergoing prostatic artery (PA) embolization (PAE) for benign prostatic hyperplasia.

Materials And Methods: From January 2012 to January 2013, 15 patients (age range, 59-81 y; mean, 68 y) with moderate- or severe-grade lower urinary tract symptoms, in whom medical management had failed were enrolled in a prospective United States trial to evaluate PAE. During pelvic angiography, 15 cone-beam CT acquisitions were performed in 11 patients, and digital subtraction angiography was performed in all patients.

Percutaneous irreversible electroporation of surgically unresectable pancreatic cancer: a case report.

The present report describes a case of percutaneous irreversible electroporation (IRE) in a 78-year-old man with surgically unresectable stage III (tumor/node/metastasis stages, T4N0M0) pancreatic adenocarcinoma. Two ablations were performed for a 4.1-cm mass encasing the celiac and superior mesenteric artery.

Power injection of microcatheters: an in vitro comparison.

Purpose: To determine the tolerance of 0.021-inch and 0.027-inch microcatheters to power injection in an in vitro flow model.
