[5][6] She managed to collect another bronze in the 57-kg division at the 1999 Pan American Games in Winnipeg, Manitoba, Canada, but missed a chance to campaign for her 2000 Olympic bid due to spinal disc herniation, nearly reaching her early retirement from judo.

[8] Zangrando got off to a firm start with an effortless victory over China's Liu Yuxiang, before falling short in the quarterfinals by an ippon and an uchi mata (inner thigh throw) from Dutch judoka Deborah Gravenstijn.

In the repechage round, Zangrando lost to Italy's Cinzia Cavazzuti on a thirteen-second waza-ari tiebreaker after she received a yuko and conceded with only three shido penalties over her opponent by four, resulting to her elimination from the tournament.

[9][10][11] When her country Brazil hosted the 2007 Pan American Games in Rio de Janeiro, Zangrando overpowered U.S. judoka Valerie Gotay to claim her first and only career gold in the 57-kg division by the enchantment of her home crowd.

[12][13] Although she decided not to pursue her third Olympic bid, Zangrando added a silver to her career hardware in the same category at the 2009 Pan American Judo Championships in Buenos Aires, Argentina, losing the final to Cuba's Yurisleydis Lupetey.
