Background: The bovine pericardium is a good alternative material to the autogenous vein in vascular reconstruction. This study aimed to evaluate the results of angioplasty in venous reconstruction using bovine pericardium and identify the risk factors for significant complications. Material and Methods: A retrospective review was performed of the demographic data, clinical characteristics, and complications of patients who underwent vessel repair using bovine pericardium between February 2012 and December 2020. Univariate analysis was used to compare complication frequencies within several categories. Results: There were 36 cases of patch angioplasty using bovine pericardium. The median age was 65 years; 61% of them were men. Of the 36 venous repairs, 31 (86.1%) were from cancer surgery and five (13.9%) were from iatrogenic injury. Patch shape was used in 27 cases (75.0%), while tube shape was used in nine cases (25.0%). The incidence of occlusion and partial thrombus was five (13.9%) and three (8.3%) cases, respectively. Of the nine tube-shaped angioplasties, four (44.4%) required reoperation due to early thrombosis (three cases) and hematoma (one case). Conclusion: The use of a bovine pericardial patch in the reconstruction of a damaged vein from tumor invasion or iatrogenic injury is feasible. However, the complication rate of vessel patency remains substantial, especially in cases of iatrogenic injury or when a tube-shaped form is used for repair. [ABSTRACT FROM AUTHOR]
