Measures of intraoperative vasospasm by harvesting method

	Harmonic scalpel (n = 15)	Electrocautery (n = 29)	P value
Luminal volume
Baseline (mm³)	1079 ± 112	906 ± 86	.237
After harvesting (mm³)	921 ± 80^*	559 ± 69^†	.003
Percentage change between scans	8.8 ± 7.1	34.5 ± 6.2	.015

Data are expressed as mean values ± standard error.

P = .87 versus baseline.
