Why the study?
Cancer-related stroke occurs in elderly patients with risks varying by cancer type, but immediate recurrent thrombosis in separate large vessels during thrombectomy remains poorly understood.
Demonstrates that recurrent large vessel occlusion during thrombectomy in cancer patients can be caused by direct tumor emboli rather than typical thromboembolism.

Tumor emboli may cause recurrent LVO during EVT in cancer patients; hypothesis-generating for tailored strategies.
Cancer-related stroke is occasionally observed in elderly patients, with varying risks depending on the cancer type. Traditionally, lung and pancreatic cancers exhibit the highest stroke risk by increased venous thromboembolism associated with cancer-induced hypercoagulability. However, we present a novel case of immediate recurrent thrombosis in separate large vessels, including the basilar and internal carotid arteries, during endovascular thrombectomy. Retrieved thrombus was identified as cancer cells in a patient with sarcomatoid carcinoma and multifocal metastases to the spine and iliacus muscle.
