Interstitial laser photocoagulation of normal lung parenchyma in rats

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...

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...

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...

THERAPEUTIC EFFECTS OF LASER PHOTOCOAGULATION AND VITRECTOMY IN EALES\'DISEASE

Eales' disease is an idiopathic obliterative retinal vasculopathy that is treated with laser photocoagulation, and/or vitrectomy. In order to determine visual outcomes and regression of retinal neovascularization following scattered peripheral retinal photocoagulation, and/or vitrectomy in cases with Eales' disease, we did a retrospective study of the records of these patients treated in La...
