Rare case of epithelioid hemangioendothelioma in the right innominate vein-An innovative diagnostic approach

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.
