DeBrincat made it 4-3 at 8:53 with a shot from the right circle.
Pietrangelo tied it 4-4 at 9:40 when his point shot went off the leg of Chicago forward Kirby Dach.
"I don't score if [Mattias Janmark isn't] front of net like that," Pietrangelo said of his teammate creating a screen. "When you get inside there and start creating a little bit of chaos, teams have to think twice about who to cover."
Dominik Kubalik gave Chicago a 1-0 lead at 10:02 of the first period on a one-timer that deflected off Vegas defenseman Shea Theodore. Toews made it 2-0 at 14:52 with a redirected shot, and Dylan Strome extended the lead to 3-0 at 18:16 from the left circle on a rebound of Caleb Jones' shot.
"I thought the first two periods were pretty good," Kubalik said.
