Objective: To compare bursting tension of arteries ≥3mm in diameter sealed with ultrasonic energy (UE) with arteries ligated with suture. Study Design: Experimental, nested factorial design. Sample Population: Vascular segments from canine cadavers. Methods: Arterial segments (12) were collected from each of 16 canine cadavers and equally divided into 2 groups based on vessel diameter (medium, 3.0–<4.5mm; large, 4.5 –≤6.0mm). Arterial specimens (3) from each group were sealed with either UE (Harmonic Scalpel®, HS, power level 3) or suture ligation. The mean bursting pressure and tension were determined and compared. Results: Bursting tension was significantly higher (P<.0001) for sutured arteries than UE-occluded arteries, irrespective of size. Bursting tension was significantly higher (P=.0013) for medium than large UE-occluded arteries, whereas there was no difference associated with size for ligated arteries. UE energy failed to seal 1 medium artery and 7 large arteries. Compared with normal blood pressure, bursting pressures were 3.5 times greater for sutured arteries irrespective of size, 1.8 times greater for medium UE-occluded arteries, and approached normal blood pressure for large UE-occluded arteries. Conclusion: At the power level tested, UE should not be used to seal arteries >4.5mm in diameter. Suture provided an optimal seal for arteries ≤6.0mm in diameter. Clinical Relevance: Use of UE to occlude arteries during laparoscopic surgery is advantageous because only 1 instrument is required to simultaneously cut and coagulate tissue, but care should be exercised where large arteries might be encountered.
