Summary
This study presents a modified radical nephrectomy with vena caval tumor thrombectomy during hypothermic circulatory arrest. This technique minimizes tumor embolization, enhancing procedural safety without increasing morbidity.
Area of Science:
- Urology
- Oncology
- Cardiovascular Surgery
Background:
- Renal carcinoma with vena caval tumor thrombus presents surgical challenges.
- Hypothermic circulatory arrest (HCA) is used for complex surgeries.
- Minimizing risks like tumor embolization is crucial.
Purpose of the Study:
- To present a modified radical nephrectomy and vena caval tumor thrombectomy technique.
- To evaluate the safety and efficacy of this modified procedure under HCA.
- To reduce the risk of tumor fragmentation and embolization.
Main Methods:
- A modified radical nephrectomy and vena caval embolectomy were performed.
- The procedure was conducted during HCA in 16 consecutive patients.
- Data were compared to a previous series using conventional techniques.
Main Results:
- The average HCA time increased by 6 minutes.
- Tumor manipulation before HCA was eliminated, minimizing embolization risk.
- No significant differences in blood loss or complications were observed compared to conventional methods.
Conclusions:
- Radical nephrectomy with vena caval embolectomy during HCA is safe.
- This modified approach increases procedural safety.
- The technique does not lead to significant additional morbidity.
