Presented herein are the findings of a comparative experimental study of 64 novel patches made of porous polytctrafluoroethylene (PTFE). The PTFE explants with various number of technological layers were examined both in vitro and in vivo. The authors performed plasty of the canine aorta with explants followed by morphological assessment of the tissues with PTFE at various terms of follow up. Based on the results obtained during intraoperative assessment of the patches' properties and histological examination thereof, we selected better patches for plasty of the aorta and major arteries to be implemented into clinical practice.

KEY WORDS: vascular patch, explant, PTFE, aorta, morphology, experiment.
