Iatrogenic superior vena cava syndrome. A new entity

Area of Science:

• Oncology
• Vascular Surgery
• Internal Medicine

Background:

• Central venous catheters (Broviac or Hickman) are essential for cancer patient management.
• Superior vena cava syndrome (SVCS) is a serious complication often associated with malignancy.
• Understanding non-tumoral causes of SVCS is crucial for timely diagnosis and treatment.

Observation:

• Four cancer patients presented with symptoms of superior vena cava syndrome.
• The syndrome developed after the insertion of a central venous catheter (Broviac or Hickman).
• Mediastinal tumoral involvement was ruled out in all observed cases.

Findings:

• Central venous catheter placement can precipitate SVCS in cancer patients.
• Absence of mediastinal tumor suggests catheter-related thrombosis or compression as the etiology.
• This finding underscores the importance of considering iatrogenic causes for SVCS.

Implications:

• Clinicians should consider catheter-related complications in the differential diagnosis of SVCS in cancer patients.
• Prompt diagnostic workup, including imaging, is necessary to identify the cause of SVCS.
• Appropriate management strategies should be tailored to the underlying cause, whether tumoral or non-tumoral.
