Resecting Lower Segment Inferior Vena Cava Leiomyosarcoma With Middle Segment Extension While Avoiding Renal...

Area of Science:

• Oncology
• Vascular Surgery
• Surgical Pathology

Background:

• Primary leiomyosarcoma of the inferior vena cava (IVC) is a rare, aggressive malignancy.
• Complete tumor resection with clear margins is the only curative treatment.
• IVC leiomyosarcomas often require nephrectomy or renal reimplantation due to anatomical location.

Observation:

• A 65-year-old female presented with a lower segment IVC leiomyosarcoma extending into the middle segment.
• The tumor involved critical vascular structures adjacent to the kidneys.

Findings:

• Successful surgical resection and reconstruction of the IVC leiomyosarcoma were achieved.
• The surgical strategy preserved native kidney function, avoiding nephrectomy or renal reimplantation.

Implications:

• This case demonstrates a viable surgical technique for IVC leiomyosarcoma that minimizes renal morbidity.
• Preserving renal function during IVC tumor resection is achievable, improving patient outcomes.
• Highlights the importance of tailored surgical approaches for rare vascular tumors.
