Laser ablation treatment strategy

A number of other strategies have been investigated in order to improve the quality (selectivity and fluxes) or the synthesis efficiency of zeolite membranes by pre-treatment of the support. Most of these treatments are listed in [49], and include laser ablation, utilisation of diffusion barriers to limit sol infiltration, oxidation of stainless-steel supports, deposition of iron oxide to favour heterogeneous nucleation on the support and the use of acid attacks to activate the surface. 

Liver resection can therefore be offered only to a small number of patients with a good chance of success. There is a demand for additional treatments to improve the success of resection and to diminish the incidence of recurrence after surgery, particularly in patients for whom surgery is not an option. Alternative methods include oncologic strategies, such as systemic or locoregional chemotherapy, and interventional techniques, including percutaneous alcohol injection, transarterial chemoembolization, microwave ablation, and percutaneous laser treatment (Lin et al. 1997).
