PURPOSE: The applicability of absorbable materials as ligatures of pulmonary vessels has not been described. The present study compares tissue reactions around sites of pulmonary arteries ligated with absorbable material (Vicryl) and with nonabsorbable material (silk).
METHODS: Beagle dogs underwent thoracotomy and the pulmonary artery branches were ligated with silk or Vicryl under general anesthesia. The ligated arterial tissues were obtained at 4 and 8 weeks after thoracotomy and processed for pathological analysis.
RESULTS: The arteries ligated using Vicryl or silk were clinically completely sealed at 4 weeks after ligation. More inflammation and granuloma were evident at tissues surrounding ligations made with silk than with Vicryl at 8 weeks. Hyperplasia of the arterial intima continued at 8 weeks after ligation with both Vicryl and silk sutures, although some hyperplasia similar to that in nonligated arterial intima appeared at 4 weeks after ligation.
CONCLUSION: Less inflammation and granuloma are caused at arterial tissues around ligations accomplished with absorbable Vicryl than those done with nonabsorbable silk sutures, although both are equally effective. Absorbable sutures might be suitable for ligating pulmonary arteries.
