Summary
Embolization successfully treated a rare internal mammary vein pseudoaneurysm after angioplasty. This case highlights management of this uncommon complication following venous interventions.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Imaging
Background:
- Central venous stenosis and occlusion often require angioplasty.
- Complications such as pseudoaneurysms can arise post-intervention.
- Internal mammary vein pseudoaneurysms are exceptionally rare.
Observation:
- A 62-year-old male presented with worsening right upper extremity edema post-angioplasty.
- Computed tomography identified a pseudoaneurysm of the right internal mammary vein.
- The patient had undergone prior angioplasty of the right cephalic, subclavian, and innominate veins.
Findings:
- Emergency surgical embolization was performed successfully.
- The procedure addressed the pseudoaneurysm of the internal mammary vein.
- This intervention resolved the patient's symptoms.
Implications:
- Central venous pseudoaneurysms are a rare but serious complication of angioplasty.
- The specific anatomy of the internal mammary vein presents unique challenges.
- Effective management strategies for this rare condition require further discussion and consideration.
