The development of the video laparoscopic surgery has brought the necessity of standardizing the artery ligation with titanium clips in order to minimize operation time. The aim of this study is to investigate and compare the arterial ligation with cotton thread, and also with one, two or three titanium clips. Consequently, eigthy arteries of twenty mongrel s dogs were utilized. Each of the dog had their right and left axillary arteries, as well as the rigth and left femoral arteries used. Those arteries had been previously distributed in 4 groups, being previously chosen by lot and in turns. After arterial dissection and ligation, the arteries were submitted to 100 mmHg and 300 mmHg of pressure, and a pulsation rate of 70 bumps per minute, that was obtained by an arterial pressure simulation machine. There was a liquid escape from 3 arteries, which belonged to the one-titanio-clip group. This escape, that is statistically significant occurred in less than 15 minutes. Furthermore, the results show that the arterial ligation with one titanio clip has a great probability of escaping, contrary to the ligation done with cotton thread, as well as the ones done with two or three titanium clips. Therefore, there is no difference between the ligation with cotton thread and two or three titânio clips, if they are submited to 300 mmHg of pressure and a pulsation rate of 70 bumps per minutes.
