Abstract
BACKGROUND: The CorMatrix (CorMatrix Cardiovascular, Roswell, Ga) biologic extracellular patch derived from porcine small intestinal mucosa provides a biologic scaffold for cellular ingrowth and eventual tissue regeneration. It has been used in a variety of applications, including cardiac and vascular repair procedures. METHODS: CorMatrix was used as a patch arterioplasty for femoral artery repair in conjunction with endarterectomy for seven separate procedures in six patients (one patient underwent staged, bilateral femoral procedures). RESULTS: Patients were a median age of 67 years (interquartile range, 3.6 years). Six of seven procedures (86%) were performed on male patients. There were no operative deaths. Three of seven procedures (43%) resulted in significant early complications. Two procedures (29%) resulted in catastrophic biologic extracellular matrix patch disruption (11 and 19 days after initial procedure), requiring emergency exploration, patch removal, and definitive repair with vein patch arterioplasty. Both patches demonstrated an absence of growth on culture. One procedure (14%) resulted in groin pseudoaneurysm formation. Use of the CorMatrix patch was suspended upon recognition of significant complications. CONCLUSIONS: Use of CorMatrix patch in the femoral artery position demonstrates a high incidence of early postoperative complications, including catastrophic patch disruption and pseudoaneurysm formation.
