RESUMO

A patent foramen ovale is almost physiological (15% of the population) but can be associated with some pathological situations in which its closure can be considered. The only medical indication currently accepted is a right-left shunt without elevation of the right pulmonary pressure, whose most famous pattern is the rare platypnea-orthodeoxie syndrome. PFO may be responsible for diving decompression accidents. Before taking the decision of closing a PFO, each situation must be discussed on a case to case basis. In spite of the possible link between some kinds of migraine and PFO, according to current knowledge, there is no evidence of the efficiency of PFO closure in this situation. The secondary prevention of a cryptogenic ischaemic cerebrovascular attack on a young person with a PFO associated to a membranous septum aneurysm, is the most commonly considered indication, but we lack valid data for this indication. The PFO closing procedure is well codified and its success rate is close to 100%, with rare major complications. Residual permeability within the prosthesis ensuring the closure of the PFO decreases gradually to get under 15% after six months. The clinical result is often dramatic when treating right-left shunts. As far as the secondary prevention of cryptogenic ischaemic cerebro vascular attacks in young people is concerned, there might be some clinical benefit, but we are waiting for the results of ongoing randomized and scheduled studies.

RESUMO

El objetivo de este trabajo es presentar el análisis cefalométrico de planos múltiples realizados en dos pacientes, ambos de proporciones armónicas, los cuales fueron radiografiados en plano frontal con incidencia posteroanterior y en plano basal. Sobre cada radiografía se realizaron tres calcos tomando como referencia estructuras en tres planos diferentes. El análisis consistió en la determinación de parámetros discriptivos. Uno de los pacientes no presentó asimetrías mientras que el otro excedió los límites de tolerancia propuestos por Ricketts
