[Interstitial implantation of ¹²⁵I seed therapy for recurrent ovarian cancer].

Objective: To explore the feasibility, short-term efficacies and complications of computed tomography (CT)-guided ¹²⁵I interstitial implant therapy for recurrent ovarian cancer.

Methods: From October 2009 to November 2010, a total of 25 lesions for 12 patients were diagnosed as recurrent ovarian cancer by positron emission tomography/computed tomography (PET/CT). Among 25 lesions, 21 underwent ¹²⁵I seed implantation.

Experimental study of destruction to porcine spleen in vivo by microwave ablation.

Aim: To discuss the safety, feasibility and regularity of destruction to porcine spleen in vivo with congestion and tumescence by microwave ablation (MWA).

Methods: Ligation of the splenic vein was used to induce congestion and tumescence in vivo in five porcine spleens, and microwave ablation was performed 2-4 h later. A total of 56 ablation points were ablated and the ablation powers were 30-100 W.

Radioablation settings affecting the size of lesions created ex vivo in porcine livers with monopolar perfusion electrodes.

Rationale And Objectives: To explore the morphological characteristics of ablated lesions and find which combination of duration, temperature, and power was preferable to create largest lesion size with monopolar perfusion electrodes.

Materials And Methods: Using monopolar perfusion electrodes to create 72 lesions in 30 excised porcine livers with radiofrequency radiation at different durations (5, 10, 15, and 20 minutes), temperatures (83 degrees C, 93 degrees C, 103 degrees C, and 113 degrees C), and powers (20, 30, and 40 W). Lesion volumes were calculated from longitudinal diameters and transverse diameters.
