Coronary artery dissection. Follow-up by MDCT.
and a feature consistent with a thrombus, probably located in the false lumen (Figure, D). Based on these findings, a new coronary angiography with possible surgical revascularization was planned, but 12 hours after the MDCT examination, the patient experienced an episode of chest pain with ST-segment elevation from V1 to V5, complicated by electromechanical dissociation, and culminating in death. A post-mortem study was not performed. This case illustrates the usefulness of MDCT for follow-up of coronary stents located in proximal segments, and for identifying specific complications: extension of a dissection and even visualization of a coronary thrombus.
Disección coronaria. Seguimiento con TCMD
(fig. 1B y C), detectandose ademas progresion de la diseccion hasta segmento medio de circunfleja con imagen compatible con trombo, probablemente en su falsa luz (fig. 1D). Ante estos hallazgos, se planeo nueva coronariografia con vistas a una posible revascularizacion quirurgica, pero 12 h despues del examen con TCMD el paciente experimento episodio de dolor toracico con elevacion del ST de V1 a V5, complicado con disociacion electromecanica y muerte. No se realizo necropsia. El caso demuestra la utilidad de la TCMD en el seguimiento de los stents coronarios localizados en segmentos proximales, asi como en la identificacion de complicaciones concretas: extension de la diseccion e incluso v…
