RATIONALE: Cancer and chemotherapy individually confer hypercoagulability and increased risks of thrombosis. Most thromboembolic complication after breast cancer chemotherapy was venous thrombosis after multiagent chemotherapy. Arterial thrombosis is extremely rare in early breast cancer patients receiving adjuvant chemotherapy.PRESENTING CONCERNS: A 55-year-old woman with right breast cancer presented to the emergency department with sudden pain, numbness, and swelling in her left hand. She underwent breast conserving surgery and sentinel lymph node biopsy 2 months before the visit. She received the second cycle of adjuvant Adriamycin-cyclophosphamide chemotherapy 5 days before.INTERVENTIONS: Computed tomography angiography revealed acute arterial thrombosis in the left brachial, radial, and ulnar arteries. Unfractionated heparin was initiated immediately, followed by brachial and radial-ulnar thrombectomy, restoring perfusion to the extremity. The postoperative course was uncomplicated; she was discharged on warfarin at a daily dose of 4 mg.


Chemotherapy was discontinued. Anticoagulation with warfarin was continued. She subsequently received adjuvant endocrine therapy with an aromatase inhibitor and adjuvant radiotherapy.MAIN LESSONS: Despite the low risks of arterial thrombosis in breast cancer, it is a devastating complication with significant morbidity and mortality. Thromboprophylaxis should be considered in those at risk. Immediate anticoagulant therapy and surgical intervention should be considered in affected cases.
