VALUE OF THE SPIRAL ANGIOSCANNER WITH 3-D IMENSIONAL RECONSTRUCTION IN THE OPERATIVE STRATEGY OF UNIFOCALISATIONS (ONE CASE)

One of the difficulties of surgical treatment of pulmonary atresia wit h patent septum by unifocalisation resides in the accurate diagnosis o f the different collateral vessels to the lung in order to optimise th e surgical approach : anterior or posterolateral thoracotomy, and to d etermine the type of operation : one or two stages repair. Conventiona l angiography, even using different views, cannot always give an accur ate representation of the anatomy of the different collateral vessels, especially their relationship to the bronchial structures. The author s report the contribution of spiral angioscanner with three dimensiona l reconstruction in the determination of the operative strategy of a c ase of pulmonary atresia with patent septum.
