Ablation Therapy

Microwave ablation (MWA) by using coaxial antennas is a promising alternative for breast cancer treatment. A double short distance slot coaxial antenna as a newly optimized applicator for minimally invasive treatment of breast cancer is proposed. To validate and to analyze the feasibility of using this method in clinical treatment, a computational model, phantom, and breast swine in vivo experimentation were carried out, by using four microwave powers (50 W, 30 W, 20 W, and 10 W). The finite element method (FEM) was used to develop the computational model. Phantom experimentation was carried out in breast phantom. The in vivo experimentation was carried out in a 90 kg swine sow. Tissue damage was estimated by comparing control and treated micrographs of the porcine mammary gland samples. The coaxial slot antenna was inserted in swine breast glands by using image-guided ultrasound. In all cases, modeling, in vivo and phantom experimentation, and ablation temperatures (above 60°C) were reached. The in vivo experiments suggest that this new MWA applicator could be successfully used to eliminate precise and small areas of tissue (around 20–30 mm2). By modulating the power and time applied, it may be possible to increase/decrease the ablation area.

The Face

Our goal is to describe a case of Harlequin syndrome associated with microwave ablation in the treatment of a symptomatic paraspinal mass in a child, along with a summary of the literature. Our patient is the only known case of persistent Harlequin syndrome associated with microwave ablation treatment of a symptomatic paraspinal mass. Harlequin syndrome is a rare neurological condition characterised by unilateral sweating and flushing of the face, neck and/or upper chest. The specific mechanism is unclear, but the majority of cases are believed to be a result of contralateral lesions along the sympathetic chain. CT-guided microwave ablation therapy is a minimally invasive technique used as an alternative to surgery in this case due to the risk and morbidity associated with excision of the mass. There is limited literature assessing the use and inherent risk of developing complications following microwave ablation to the paraspinal region in the paediatric population.
