Abstract

An acute abdominal mobile aortic thrombus is a very unusual finding, and this is a potential source of arterial embolism. Mobile aortic thrombus mostly occurs in a diffuse atherosclerotic and aneurysmal aorta. Chemotherapy agents have been documented as a possible rare cause of acute arterial thrombus. We report acute abdominal mobile aortic thrombus post-chemotherapy for pancreatic and stomach cancer.

  Fig. 1 A 55-year-old male with abdominal aortic thrombosis after chemotherapy. A. Abdominal CT shows infrarenal intraluminal abdominal aortic thrombus (arrow). B. Fourteen days before chemotherapy, abdominal CT shows no thrombus (arrow). C. One month after thrombolysis, abdominal CT shows disappeared previous infrarenal thrombus (arrow).

• 

  Fig. 2 A 44-year-old female with abdominal aortic thrombosis after chemotherapy. A. Abdominal CT shows intraluminal aortic thrombus with right renal infarction (arrow). B. Seven days before chemotherapy, abdominal CT shows no thrombus (arrow).

• 

  Fig. 3 A. Angiogram shows occlude balloon in left renal artery (left upper black arrow) and left iliac artery (left lower black arrow). Abdominal aortic thrombus is noted by intraluminal filling defect (right black arrow). B. A wire-directed balloon catheter thrombectomy was performed using a 27 mm Equalizer balloon catheter (arrow). C. After balloon catheter thrombectomy, angiogram shows successful removal of the aortic thrombus (arrow).

• 

  Fig. 4 Seven days after chemotherapy, abdominal CT shows disappeared thrombus and slightly recannalization of right renal artery.
