Autologous pericardium used for reconstruction of left innominate vein in patient with mediastinal venous aneurysm:a case report

Abstract

Background Mediastinal venous aneurysm is a very rare disease and can be easily misdiagnosed. Patients are often asymptomatic while venous aneurysm of large size with adjacent structures oppressed can lead to discomfort. The surgical treatment for aneurysm of large vessels is often complex and challenging. Case presentation We reported a 52-year-old man with mediastinal mass who received operation on July 2019 in our hospital. Left innominate vein aneurysm was diagnosed during operation with superior vena cava involved. The aneurysm was resected and pericardium was taken to repair part wall of superior vena cava and reconstruct left innominate vein. The patient’s postoperative course was uneventful. Conclusions Venous aneurysm should be considered when mediastinal mass has no clear boundary with large veins or even seems to connect with them. Magnetic resonance imaging, computed tomographic angiography and invasive venography can be performed to further evaluate the mass once diagnosis of venous aneurysm was suspected. Using pericardium to repair large veins is a good choice which is safe and costless.

“…The patient's symptoms were signi cantly improved after the operation. Cheng Fang [10] also reported a case of left brachiocephalic vein tumor with accumulated superior vena cava.…”

Case Report: Surgical Therapy for Left Innominate Vein Aneurysm Under Thoracoscopy

“…Mediastinal venous aneurysms are extremely rare and only a few cases have been reported in the literature, most of which occur in the superior vena cava (1). Mediastinal vein aneurysms are classified into fusiform and saccular types (3).…”

“…Isolated left innominate vein aneurysms may be asymptomatic and are often discovered incidentally during routine chest imaging. However, they are sometimes detected due to the occurrence of complications provoked by the aneurysms (1). If the aneurysm is large and compresses surrounding structures, non-specific symptoms such as palpitation and dyspnea may occur (2).…”
