Aortic thrombosis resolved with enoxaparin in a patient treated with cisplatin-based regimen for small cell lung...

We present a rare case of a thrombus at the aortic arch found 1 month after cisplatin-based chemotherapy in a 50-year-old patient with a diagnosis of small cell lung cancer; there were no symptoms related to the thrombus. This patient did not have any predisposing factors for the development of an aortic thrombus before the chemotherapy was initiated. After immediate treatment with low molecular weight heparin (enoxaparin), the thrombus improved without any additional complications. Thus, we suggest that a hypercoagulable status possibly created by both the malignancy and cisplatin-based chemotherapy may have played a significant role in the development of the aortic thrombus.
