Summary
Managing juxtahepatic and intrapericardial inferior vena cava (IVC) tumors requires advanced techniques. Venovenous bypass (VVB) and cardiopulmonary bypass with hypothermic circulatory arrest (CBCA) offer effective surgical solutions for complex IVC pathologies.
Area of Science:
- Vascular Surgery
- Surgical Oncology
- Cardiothoracic Surgery
Background:
- Juxtahepatic and intrapericardial inferior vena cava (IVC) surgeries present significant vascular control challenges.
- Complex pathologies in this region necessitate specialized surgical approaches.
Purpose of the Study:
- To describe surgical strategies for managing juxtahepatic and intrapericardial IVC pathologies.
- To evaluate the efficacy of venovenous bypass (VVB) and cardiopulmonary bypass with hypothermic circulatory arrest (CBCA) in these complex cases.
Main Methods:
- Retrospective review of 10 patients with diverse IVC pathologies.
- Surgical interventions included VVB for cases without atrial involvement.
- CBCA with deep hypothermia was employed for tumors extending into the right atrium.
Main Results:
- Eight out of ten patients had successful outcomes and were discharged within 4 weeks.
- VVB was used in patients without atrial involvement (mean bypass time: 40 minutes).
- CBCA was used for right atrial tumor extension (mean bypass, aortic cross-clamp, and arrest times: 152, 92, and 36 minutes, respectively).
Conclusions:
- VVB and CBCA are viable and effective surgical options for complex IVC pathologies.
- Careful patient selection and tailored surgical techniques are crucial for successful outcomes.
- Despite challenges, a high success rate was achieved in this patient cohort.
