Arterial embolism in malignancy: The role of surgery

Abstract

Background: Peripheral arterial embolism from malignant disease is uncommon and a rare cause of limb ischemia. In the acute setting, patients can present with severe ischemia of either the upper or lower limb, and urgent surgical intervention is often required to avoid severe debilitation and limb loss. Patients: Our case series comprised three patients who presented with upper and lower limb ischemia and were found to have concomitant malignancy. All three patients were female, with a median age of 54.3 years, and none of the patients was on active chemotherapy. One presented with stage IIb uterine carcinoma, one with stage IIIb ovarian carcinoma, and the other with stage IIIb cervical carcinoma. These patients were referred for vascular management, with two being acute and the other acute on chronic. Results: Of the three patients, two presented with acute limb ischemia and underwent arterial thrombectomy, one of the upper and the other the lower limb. The third patient, with acute-onchronic upper limb ischemia, was treated conservatively with intravenous heparin followed by oral anticoagulation. All three had limb salvage and survival outcome at 1 year post-treatment. Conclusion: In this small series, surgical intervention in two patients and conservative management in the other patient led to limb salvage with a reasonably good quality of life. Even though the long-term survival for patients with malignant disease is generally poor, surgical intervention can achieve limb salvage with a reasonably good quality of life.
