Secondary Endovascular Repair of a Reconstructed Superior Vena Cava in a Patient with a Malignant Thymic Epithelial Neoplasm

Introduction

Thymic neoplasms account for approximately 50 % of anterior mediastinal masses. The vast majority of thymomas are cytologically bland neoplasms that exhibit an indolent clinical course [[1]]. Aggressive tumors can cause venous obstruction from extrinsic compression or direct invasion of the superior vena cava (SVC) or the innominate veins (IV s), exhibiting a malignant behavior associated with a poor prognosis. Complete resection of even an extensively invasive tumor remains the cornerstone of therapy and is the most critical factor in determining long-term survival [[2]].

We present a case of a young patient with a malignant thymoma that was treated with tumor resection together with SVC reconstruction. A secondary endovascular procedure was required due to early thrombosis of the reconstructed SVC.
