ABSTRACT
BACKGROUND AND AIMS: Epithelioid hemangioendothelioma is a rare malignant vascular tumor with limited literature. AIMS: We reported an innovative endovascular biopsy of the right innominate vein tumor. MATERIALS AND METHODS: Endovascular suction thrombectomy was performed with multipurpose catheter and constant negative pressure under fluoroscopic guidance. RESULTS: Epithelioid hemangioendothelioma was diagnosed preoperatively and a complete margin-free tumor resection with patch repair of the right innominate vein was achieved via sternotomy. DISCUSSION: Preoperatively diagnosis is usually not available due to lesions' location. Identifying malignant vascular tumors becomes valuable to guide the surgical treatment. CONCLUSIONS: In this case report, this innovative endovascular approach led to a rare preoperative diagnosis of EHE and subsequent margin-free resection.
