| Popis: | The Possis® polytetrafluoroethylene Permaflow coronary graft incorporates a Venturi resistor within the graft. Insertion is constructed by creating an anastomosis to the superior vena cava with subsequent anastomoses in sequence to coronary arteries requiring grafting. Finally, the graft is sewn to the aorta. The Venturi resistor controls flow through the aortocaval fistula, maintaining systemic pressure proximal, permitting systolic and diastolic flow to the grafted coronary arteries while maintaining constant flow through the graft. Animal studies demonstrated long-term patency. This graft was implanted in a patient with unstable angina pectoris and inadequate native conduit. Catheterization 6 weeks postoperative revealed patency of all anastomoses. (J Card Surg 1993; 8:439–442) |
