| Popis: | A sixty three year old woman suffering fromTakayasu’s arteritis with involvement of the aortic arch,subclavia arteries and occlusion of the right pulmonaryartery, developed progressive precordial pain. Exerciseelectrocardiogram disclosed ST segment depression.Coronary arteriograms demonstrated no coronarystenosis, but collateral circulation arising from circumflexcoronary artery to right pulmonary artery. The collateralblood flow was considered to be of great importance, andcausing the coronary steal syndrome, leading to anginapectoris.Mulher de 63 anos com arterite de Takayasu, envol-vendo arco aortico, arterias subclavias e arteria pulmo-nar direita, com dor precordial progressiva. Oeletrocardiograma de esforco revelou depressao do seg-mento ST. A cineangiocoronariografia nao mostrou le-soes estenoticas ostiais e nem epicardicas e, sim, comuni-cacao entre a arteria coronaria circunflexa e o ramo dolobo superior da arteria pulmonar direita. O fluxosanguineo atraves da comunicacao arterial foi conside-rado de grau importante, provocando, provavelmente,sindrome do roubo de fluxo coronario e, consequentemen-te, o quadro de angina de peito com carater progressivo. |
