This year the new international guidelines of WIST (The World Federation for Interventional Stroke Treatment) on the physician’s training in the interventional acute stroke treatment were published. WIST multispecialty guidelines outline competency and quality standards for physicians and centers to perform safe and effective endovascular stroke treatment with mechanical thrombectomy. The role of quality control and quality assurance is highlighted. WIST establishes an individualized approach to acquiring clinical knowledge and procedural skills to meet the competency requirements for certification of interventionalists of various disciplines and stroke centers in endovascular treatment. WIST guidelines encourage acquisition of skills using innovative training methods such as structured supervised high-fidelity simulation and procedural performance on human perfused cadaveric models. In Poland in 2018 a pilot program on mechanical thrombectomy was established, however endovascular acute stroke treatment is still underused due to limited patients access to stroke centers and too small number of operators.

This article aims to discuss the notion of environmental damage under the CLC 1992 and FUND 1992 as stated in the new Guidelines for Presenting Claims for Environmental Damage prepared by the International Oil Pollution Compensation Funds. That approach is contrasted with the solution adopted in the United States of America under the OPA. Particular attention is given to the problems of compensation for lost services of the environment, as well as providing alternative environment as a restoration measure. The judgments of French and Spanish courts in the Erika and Prestige cases are discussed, raising questions as to suitability of the CLC 1992/FUND 1992 system.
