Abstract
Background: The Cabrol patch is a bovine pericardial patch that addresses intraoperative aortic root bleeding. The technique has been linked to challenges such as postoperative bleeding, pseudoaneurysm formation, root thrombosis, and fistula formation. To date, there is limited data on perioperative and postoperative outcomes following Cabrol patch utilization. This study sought to evaluate the safety and outcomes following Cabrol patch placement to manage aortic root bleeding. Methods: 112 adult cardiac surgery patients who received a Cabrol patch from August 2018 to December 2025 were identified from the Cardiac Surgery Data Warehouse. Retrospective chart reviews were conducted using Electronic Medical Records Search Engine (EMERSE) and MiChart to verify use of a Cabrol patch or modified Cabrol patch. Postoperative bleeding, transfusion requirements, chest tube output, and postoperative CT results were evaluated, and mortality was analyzed using a Kaplan-Meier curve. Results: 109 of the 112 initially identified patients were confirmed to have undergone management of coagulopathy with a Cabrol patch. Baseline demographic and clinical characteristics (age, sex, previous cardiac surgery, comorbidities, concomitant procedures) were summarized using a descriptive characteristics table. Postoperative outcomes, including chest tube output (xx), intraoperative transfusion requirements (xx%), reoperation for bleeding prior to discharge and within 30 days (xx%), and presence of aortic root abnormality (bleeding, thrombosis, fistula, pseudoaneurysm) on the first postoperative (xx%) and most recent CT scan (xx%) were analyzed. The percentage of patients requiring intraoperative transfusion (XXX) or undergoing reoperation for bleeding within 30 days of procedure or by discharge were calculated (XXX). The Kaplan-Meier curve estimate of freedom from mortality was (XX%). Conclusion: After analyzing outcomes of patients who underwent the Cabrol patch, surgeons may confirm the technique is an efficacious and successful way to manage complex aortic root bleeding. Improved understanding of these outcomes may inform future surgical risk-assessments and support multi-institutional studies that evaluate long-term outcomes.
