Thrombosis of tibial arteries in a patient receiving tamoxifen therapy.
BACKGROUND. Tamoxifen has been used extensively as adjuvant therapy in the treatment of pre- and post-menopausal patients with breast cancer. One of its known complications is venous thromboembolism. However, arterial thrombosis has been reported rarely. METHODS. A 49-year-old patient with breast cancer had had a total mastectomy 3 years earlier. She was receiving tamoxifen therapy when she developed a sudden onset of pain and numbness of the left foot and calf. An arteriogram showed thrombosis of her tibial arteries. RESULTS. This thrombosis was lysed successfully with urokinase therapy, and tamoxifen therapy was discontinued. At follow-up 4 months later, the patient had normal circulation to both legs. CONCLUSIONS. Patients receiving tamoxifen should be monitored closely for the development of venous or arterial thromboembolism.[1]References
