Summary
Transfemoral biopsy offers a new method for diagnosing intravenous tumors. This technique successfully identified tumors in the inferior vena cava and iliac vein, providing a viable alternative to surgery.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Oncology
Background:
- Intravenous tumors, particularly in the inferior vena cava and iliac veins, pose diagnostic challenges.
- Traditional diagnostic methods may involve invasive surgery or less targeted percutaneous approaches.
Observation:
- A novel transfemoral biopsy technique was developed to target intraluminal venous masses.
- The procedure was performed via the femoral vein, accessing the inferior vena cava and iliac veins.
Findings:
- Successful histologic diagnosis was achieved in all four patients who underwent the transfemoral biopsy.
- Three patients had intraluminal masses in the inferior vena cava, and one had a mass in the iliac vein.
Implications:
- Transvenous biopsy provides a minimally invasive and effective method for diagnosing intravenous tumors.
- This technique serves as a valuable alternative to surgical exploration or percutaneous transabdominal needle biopsy.
