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.
