title: [Absorbable synthetic clips and pulmonary excision].
abstract: From the beginning of this decade, two new, 2nd generation, resorbable synthetic materials--polydioxanone and lactomer--have been able to be molded into clips which, in contrast to metallic clips, are fitted with an original locking system preventing any slipping, either transversal or longitudinal, on the vessels. An experimental study was conducted to confirm their great reliability and perfect safety on large vessels (up to 8-9 mm) of large laboratory animals--both pulmonary and systemic vessels. Positive results justified their application to pulmonary vessels in humans during surgery, the pulmonary vessel being at a much lower pressure than in the main circulatory system. These new clips possess the advantages of metallic clips and resorbable synthetic threads without their inconveniences: rapidity, simplicity and ease of application, radio-transparency and complete inertia in magnetic fields enabling radiotherapy and modern postoperative investigations (scanner, NMR...) to be carried out.
