Abstract

Objective: Surgeons shy away from using the Cabrol fistula (perigraft space to right atrium [RA] shunt) due to unfamiliarity, concern for persistent left-to-right shunting, and fear of "painting-over" anastomotic defects that will result in later problems. We review nearly 2 decades of experience with application of the Cabrol fistula in a large thoracic aortic practice, with emphasis on precise surgical techniques, early and late outcomes, and detailed radiographic analysis.

Methods: Operative records of all procedures in which the Cabrol fistula was used were retrieved and analyzed, with precise review of the details of construction of each Cabrol fistula and clinical and radiologic (echocardiographic and computed tomographic) patient follow-up.

Results: The Cabrol fistula successfully controlled the bleeding in all cases. There were no late false aneurysms at any anastomotic sites. There was no continued flow through any fistula. Good perioperative and long-term survival was achieved in these complex cases that found themselves at a very dangerous crux before application of the Cabrol fistula.

Conclusions: The Cabrol fistula is an important tool for the thoracic aortic surgeon to have in the toolbox. We found the Cabrol fistula to be extremely effective at controlling bleeding, with no late persistent fistula flow and no late false aneurysm formation. Without the fistula, outcome in these patients would likely have been lethal. We recommend the Cabrol fistula technique strongly for life-saving application in rare cases of bleeding uncontrollable by conventional methods.
