A 41-year-old woman with immunoglobulin light chain (AL) systemic amyloidosis with cardiac and gastrointestinal involvement developed multiple arterial and venous thromboembolic complications. Treatment with unfractionated heparin was complicated by life-threatening gastrointestinal bleeding. Work up for hereditary thrombophilia was unrevealing. Treatment with cyclophosphamide, bortezomib and dexamethasone combination regimen led to hematologic response without further thromboembolic complications. While thromboembolic complications have been reported in AL amyloidosis and cardiac involvement, this unique case highlights the complexity of the disease, the various pathogenic mechanisms at play and the difficult management decisions necessary in caring for these complex patients. A literature review of thrombembolic complications in patients with amyloidosis is presented.
