| Popis: | ObjectiveThe LigaSure device has been demonstrated to be safe for systemic vessels up to 7 mm in diameter, although its use in thoracic surgery remains understudied. We aimed to evaluate the safety of LigaSure for pulmonary artery sealing.MethodsIn 30 cases of open lung lobectomy, 15 small pulmonary arteries (diameter, 3-5 mm) and 15 thick pulmonary arteries (diameter, 6-8 mm) were divided with LigaSure. Before closure of the thoracotomy, the vessel stumps were ligated proximal to the sealing zone, resected, and preserved in formaldehyde for histopathologic examination. In a control group, a similar number and size of pulmonary arteries were suture-ligated. The burst pressure of the pulmonary arteries from the resected lung lobes was measured.ResultsThe mean burst pressure of small pulmonary arteries was 4.3-fold less after sealing than after ligation (315 ± 213.1 mm Hg vs 1345 ± 256 mm Hg; P 5 mm in diameter have a burst pressure that is 50% less than that of smaller arteries (P |
