Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging

Background:

  • Aneurysm of the left brachiocephalic vein is an exceptionally rare condition, with fewer than 40 documented cases.
  • This report details a unique case of an asymptomatic venous aneurysm.

Purpose of the Study:

  • To present a case of left brachiocephalic vein aneurysm diagnosed via preoperative imaging.
  • To discuss the surgical management of this rare venous anomaly.

Main Methods:

  • A 61-year-old female presented with an incidental anterior mediastinal mass found during CT scan.
  • Dynamic computed tomography with contrast venography confirmed a left brachiocephalic vein aneurysm.
  • Surgical excision was performed using a median sternotomy approach due to aneurysm fragility.

Main Results:

  • Preoperative imaging accurately diagnosed the left brachiocephalic vein aneurysm.
  • Surgical resection via median sternotomy was completed successfully.
  • The venous wall was noted to be thin and fragile, validating the chosen surgical approach.

Conclusions:

  • Diagnosis of left brachiocephalic vein aneurysm was confirmed preoperatively.
  • Median sternotomy provided a safe and appropriate surgical route for resection.
  • The fragile nature of the venous wall necessitates careful surgical planning and execution.
