Spontaneous Closure of a Coronary Artery Bypass Graft Pseudoaneurysm Embedded in a Mediastinal Hematoma

Figure 2

Spontaneous closure of pseudoaneurysm. (a) During left heart catheterization approximately four weeks after initial presentation, there was no detectable pseudoaneurysm, consistent with spontaneous closure. (b) On follow-up CT imaging approximately three and a half months after initial presentation, there was again no detectable pseudoaneurysm and the mediastinal hematoma had decreased in size.
