[A case of impending rupture of acute aortic dissection with thrombosed false lumen in early phase].
A 73-year-old patient with acute aortic dissection in delayed shock state following sudden onset of chest-back pain and left sided hemothorax was successfully operated. Contrast enhanced CT demonstrated a crescent-shaped low density area in the descending aorta. Aortography showed ulcer-like projection (ULP) with minor leakage into left thorax, however, a flow in false lumen was not visualized. These findings suggested that the false lumen of type III aortic dissection was thrombosed in its early phase. The aneurysm was transected on left heart bypass through left thoracotomy. The entry of false lumen was found in proximal portion of descending aorta, in which fresh thrombus was filled. A graft was anastomosed and reinforced with felt strips in end-to-end. The postoperative course was uneventful. The ULP by aortography provides a possible sign of rupture in clinical course of aortic dissection.
