Figure 1A and 1B: Sagittal and axial CT image after IV contrast showing extensive wall thrombosis of the abdominal aorta (arrows) which cannot be distinguished from the aortic wall. Figure 1C: Axial MRDTI image showing chronic thrombosis (low signal intensity) in the aortic wall (arrows). Figure 1D: Axial MRDTI image showing high signal intensity representing recent thrombus in the aortic wall near the location of the PTA and rescue revascularization (arrows). and treat abdominal angina a bifurcated Dacron bypass was made from the right external iliac to the left renal artery and common hepatic artery. Collateral flow via a well-developed gastroduodenal artery ensured adequate perfusion of the superior mesenteric arterial network. We hesitated initiating anticoagulant treatment because of a high bleeding risk due to the recent major surgery, severe hypertension and renal insufficiency. Therefore, a MRDTI scan was performed
