Protein S deficiency is an inherited thrombophilia associated with an increased risk of venous thromboembolism. However, arterial thrombosis is a relative rare complication of protein S deficiency and the prognosis of these patients was worse than those without protein S deficiency in the literature. Herein we reported a 43-year-old male with protein S deficiency experiencing several times acute peripheral arterial thrombosis of left leg. Surgical thrombectomy was performed initially but later endovascular treatment (EVT) was suggested. Although EVT was successfully performed by catheter-directed thrombolysis (CDT), arterial thrombosis still recurred three months later. CDT was tried again but thrombosis could not be treated by this strategy anymore. Therefore, we used mechanical thrombectomy device (Rotarex system) and successfully regained the straight-line blood flow to the foot after the procedure. Peripheral echo showed patent flow after 6 months follow-up. In conclusion, arterial thrombosis is a relative rare complication of protein S deficiency and prognosis was not well in the literature, our case reminds physicians that Rotarex system is a safe and highly efficient device for acute PAOD even in the patients with hypercoagulable state.
