Summary
Bovine pericardium is a feasible option for venous reconstruction, particularly after cancer surgery. However, complications like occlusion and thrombosis are significant, especially with tube-shaped grafts or iatrogenic injuries.
Area of Science:
- Vascular Surgery
- Biomaterials Science
- Regenerative Medicine
Background:
- Bovine pericardium offers a viable alternative to autogenous veins for vascular reconstruction.
- Assessing its efficacy and identifying complications in venous repair is crucial.
Purpose of the Study:
- To evaluate the outcomes of angioplasty in venous reconstruction using bovine pericardium.
- To identify risk factors associated with significant complications.
Main Methods:
- Retrospective review of 36 patients undergoing bovine pericardium venous repair (February 2012 - December 2020).
- Analysis of demographic data, clinical characteristics, and complications.
- Univariate analysis to compare complication frequencies across categories.
Main Results:
- 31 repairs (86.1%) were for cancer surgery, 5 (13.9%) for iatrogenic injury.
- Patch angioplasty (75.0%) showed fewer complications than tube angioplasty (25.0%).
- Occlusion (13.9%) and partial thrombus (8.3%) were observed; 44.4% of tube repairs required reoperation.
Conclusions:
- Bovine pericardial patches are feasible for venous reconstruction due to tumor invasion or iatrogenic injury.
- Substantial complication rates, particularly regarding vessel patency, exist.
- Iatrogenic injury and tube-shaped graft use increase complication risks.
