After his victory, Khosrow rewarded his uncles with high positions: Vinduyih became treasurer and first minister and Vistahm received the post of spahbed of the East, encompassing Tabaristan and Khorasan, which according to Sebeos was also the traditional homeland of the Ispahbudhan.
Soon, however, Khosrow changed his intentions: trying to disassociate himself from his father's murder, the shah decided to execute his uncles.
The Sasanian monarchs' traditional mistrust of over-powerful magnates and Khosrow's personal resentment of Vinduyih's patronising manner certainly contributed to this decision.
Vinduyih was soon put to death, according to a Syriac source captured while trying to flee to his brother in the East.

At the news of his brother's murder, Vistahm rose in open revolt.
According to Dinawari, Vistahm sent a letter to Khosrow announcing his claim to the throne through his Parthian (Arsacid) heritage: "You are not worthier to rule than I am.
Indeed, I am more deserving on account of my descent from Darius, son of Darius, who fought Alexander.
You Sasanians deceitfully gained superiority over us [the Arsacids] and usurped our right, and treated us with injustice.
Your ancestor Sasan was no more than a shepherd."
Vistahm's revolt, like Bahrams's shortly before, found support and spread quickly.
Local magnates as well as the remnants of Bahram Chobin's armies flocked to him, especially after he married Bahram's sister Gordiya.
Vistahm repelled several loyalist efforts to subdue him, and he soon held sway in the entire eastern and northern quadrants of the Iranian realm, a domain stretching from the Oxus river to the region of Ardabil in the west.
He even campaigned in the east, where he subdued two Hephthalite princes of Transoxiana, Shaug and Pariowk.
The date of Vistahm's uprising is uncertain.
From his coinage, it is known that his rebellion lasted for seven years.
The commonly accepted dates are ca.
590–596, but some scholars like J.D. Howard–Johnston and P. Pourshariati push its outbreak later, in 594/5, to coincide with the Armenian Vahewuni rebellion.

As Vistahm began to threaten Media, Khosrow sent several armies against his uncle, but failed to achieve a decisive result: Vistahm and his followers retreated to the mountainous region of Gilan, while several Armenian contingents of the royal army rebelled and defected to Vistahm.
Finally, Khosrow called upon the services of the Armenian Smbat Bagratuni, who engaged Vistahm near Qumis.
During the battle, Vistahm was murdered by Pariowk at Khosrow's urging (or, according to an alternative account, by his wife Gordiya).
Nevertheless, Vistahm's troops managed to repel the royal army at Qumis, and it required another expedition by Smbat in the next year to finally end the rebellion.
