Interstitial laser photocoagulation for the treatment of osteoid osteoma.

We report the results of a prospective study of 23 patients in which interstitial laser photocoagulation (ILP) was used to treat an osteoid osteoma. ILP is a technique in which tumour tissue is destroyed by direct heating using low-power laser light energy delivered by thin (400 microm) optical fibres which are introduced percutaneously into the tumour under image guidance. Pain was evaluated b...

Interstitial laser photocoagulation of normal lung parenchyma in rats.

BACKGROUND Management of peripheral lung tumours may be risky in patients with poor lung function or in the elderly. A new possibility is interstitial laser photocoagulation (ILP) in which tumours are gently coagulated using thin laser fibres placed percutaneously under radiological guidance. This could have a useful palliative role in selected patients, but to be safe the effects on normal lun...

The effects of dynamic optical properties during interstitial laser photocoagulation.

A nonlinear mathematical model was developed and experimentally validated to investigate the effects of changes in optical properties during interstitial laser photocoagulation (ILP). The effects of dynamic optical properties were calculated using the Arrhenius damage model, resulting in a nonlinear optothermal response. This response was experimentally validated by measuring the temperature ri...

Interstitial Laser Photocoagulation Using 980 nm Diode Laser in Benign Thyroid Nodule: A Feasibility Study

The aim of this study was to investigate the feasibility of using 980 nm diode laser for interstitial laser photocoagulation (ILP) before clinical application in benign thyroid nodule treatment. The bovine livers were cut into blocks to irradiate with 980 nm laser through the lumen of a 20-gauge spinal needle using a fiber optic guide. Laser irradiation was performed with the output power of 2 ...
