Peripheral embolism in a patient undergoing modified Bentall procedure.

A 30-year-old male patient, who underwent Bentall De-Bono procedure due to type A aortic dissection six months ago presented to our clinic with acute lower extremity pain at rest. The warfarin dose was set to be between 2 and 3 of the international normalized ratio and the patient was discharged uneventfully after Bentall De-Bono operation. Computed tomography angiography revealed a thrombosis in the ascending aortic prosthetic graft, left iliac artery obstruction, and multiple infarcts in the spleen with an international normalized ratio of 2.2. The patient underwent reoperation and the isolated thrombus in the ascending aortic prosthetic graft was removed. Pathological examination of the material was compatible with a chronic thrombus.
