Geometric Optimization of a Mathematical Model of Radiofrequency Ablation in Hepatic Carcinoma

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Hepatic radiofrequency ablation.

HYPOTHESIS Hepatic radiofrequency ablation (RFA) is effective in treating patients with unresectable hepatic malignancies. DESIGN Case series of 123 patients with unresectable hepatic tumors or tumors with histological findings not traditionally treated by means of hepatic resection were considered for hepatic RFA. Median follow-up was 20 months. SETTING Tertiary referral center. PATIENTS...

Correction to: Efficacy of Radiofrequency Ablation in Patients with Metastatic Liver Tumors from Breast Carcinoma

In the article published in Volume 27, issue 158, 2017, the Results section in English Abstract have been published incorrectly. The correct Results is given below:   Results: The most frequent sizes of mass were 2-4 cm (n=33, 54%) and 4-5 cm (n=23, 38%). Among the patients, 35 (67.3%) had one tumor before, in 11.5% renew tumor happened, and 65.4% had one tumor after treatment. Liver tum...

Radiofrequency Ablation of Hepatocellular Carcinoma

Radiofrequency ablation of unresectable hepatic tumors.

PURPOSE To evaluate the efficacy and safety of radiofrequency ablation (RFA) in the treatment of primary and metastatic liver malignancies. MATERIALS AND METHODS Twenty-nine consecutive patients who have primary (n=9) and metastatic (n=20) liver malignancies were treated with RFA. The total number of lesions were 62 at the initiation of treatment and 28 new lesions were diagnosed at the follo...
