Recurrent thrombosis in the lower extremities after thrombectomy in a patient with polycythemia vera: A case report.

BACKGROUND

Acute arterial embolism of the extremities is a surgical emergency. Atrial fibrillation is the major etiology of acute arterial embolism of the extremities. Emergency femoral artery thrombectomy can successfully treat this issue. However, polycythemia vera (PV) may sometimes explain this medical emergency. Recurrent thrombosis in the lower extremities after thrombectomy can be found in patients with PV, and reoperation is needed for this condition.

CASE SUMMARY: A 68-year-old man in China suffered from sudden pain in the left lower extremity for 14 h. The examination in the emergency department showed a diagnosis of acute arterial embolism of the extremities combined with PV. The patient's complaint disappeared after repeat emergency thrombectomy.

CONCLUSION

Patients with acute arterial embolism of the extremities should be treated carefully, especially those who have recurrent thrombosis after emergency thrombectomy. Clinicians should be aware of PV, a rare cause of acute arterial embolism of the extremities. The combination of thrombectomy, phlebotomy, and antiplatelet and anticoagulant drugs may be a suitable therapeutic regimen for these patients.
