EXPERIMENTAL AND MORPHOLOGICAL ASPECTS OF FAILED TENDON AUTO- AND ALLOGRAFTS AFTER ACL RECONSTRUCTION IN EARLY POSTOPERATIVE PERIOD

[Decellularized cadaveric human artery for substitution of connective tissue and smooth muscle defects on the example of tunica albuginea of penis (experimental work)]

AIM

To analyze experimentally the outcomes of xenotransplantation (cadaveric artery, decellularized cadaveric artery) for tunica albuginea defects repair.

MATERIAL AND METHODS

The study included 60 chinchilla rabbits. Rabbits underwent local replacement of tunica albuginea. Animals were divided into 2 groups (group 1 - human cadaveric artery, group 2 - decellularized cadaveric artery). The result was considered after 7, 14 and 30 days postoperatively.

RESULTS

Tendency to stasis, sludge-phenomenon and ultimately development of fibrosis of transplantation area were histologically observed in group 1 after 30 days. In group 2 luminal surface of decellularized artery was smoothed, fibrin and blood elements were absent. In group 1 mean level of C-reactive protein was 3.86±0.43, 1.17±0.2 and 0.73±0.16 mg/L after 7, 14 and 30 days respectively. In group 2 the same values were 0.33±0.03, 0.23±0.03 and 0.11±0.02 mg/L. Differences were significant (t =-46.28, t = -25.95, t = -14.84; p<0.0001).
